We work where things break

Every project in our portfolio is a problem that no off-the-shelf tool — or a junior with a tutorial — could solve.

Battle-tested experience, not theory

We know how a payment node fails at 3 AM, how an API behaves under load, and where events get lost in distributed systems — because we have already fixed it.

Accountable for the outcome

We don't hand over code — we hand over a working system. Our audits are signed with the company's name. We take full ownership of mainnet deployments.

Built for complex markets

Crypto infrastructure, cross-border payments, multi-jurisdiction operations — from North America and Europe to regions where mainstream providers like Stripe and Coinbase don't operate. Complexity is our core market, not the exception.

Who we usually work with

We don't do commodity development. Most of the teams and companies that come to us need complex logic, reliable infrastructure, or an architecture built for growth.

Web3, tokenization, crypto infrastructure

DeFi, RWA, custom tokens, smart contracts, audits, blockchain integrations, payment solutions, and backend for Web3 products.

Fintech and payment systems

Billing, transaction processing, provider integrations, crypto payments, balance accounting — systems where precision and stability matter.

SaaS, services, Telegram products

Systems with subscriptions, APIs, user dashboards, events, webhooks, integrations, and load — where no-code builders no longer cut it.

Startups after MVP

The product exists, but the architecture isn't ready to grow. The system needs to be redesigned and prepared for real users or investors.

Projects with a high cost of failure

Finance, payments, user data, automation, infrastructure. Where an outage means losing money, customers, or reputation.

When standard solutions have failed

A CMS, a template, an off-the-shelf service, or a previous team didn't get the job done. It needs to be untangled, rewritten, or brought to a working state.

Not sure if your project is a fit? Describe it — we'll tell you honestly whether we can help and where to start.

Discuss your project

How work usually starts

You don't need a full spec to reach out. Most projects start with a short conversation where we break down the task and tell you honestly whether we can help.

Come without a spec

Just describe the task in your own words. We'll help you shape the requirements and suggest ways to solve it.

Come with an idea

If all you have is a concept or a project plan, we'll figure out the best way to build it and where to start.

Come with a problem

The system is live, but errors, limitations, or instability keep showing up — we find the root cause first, then propose a solution.

Start with an audit

Before development, we can review your architecture, code, or project logic and identify the risks.

Start with a short call

Usually a task description is enough. Then we'll tell you whether we can help, roughly what it costs, and what the options are.

We don't take everything

If a task doesn't fit our profile, we'll say so right away and won't waste your time.

Just describe what you need. We'll tell you whether it fits our profile and where to start.

Discuss your project

Typical project budgets

Cost depends on the complexity of the task, but here are reference points for the projects clients usually bring us. We don't sell fixed-price packages, but we can give you a ballpark upfront.

Discovery session / consultation

$150 – $500per session

A good fit if you need to understand how to structure a system, validate an idea, or make sense of an existing project.

Audit / architecture / system design

$1,500 – $5,000per engagement

Analysis of an existing system, architecture design, and preparation of a technical blueprint before development.

Backend / API / service

$3,000 – $8,000per project

Server-side development, APIs, integrations, business logic, billing, database- and event-driven systems.

Complex project / Web3 / fintech / SaaS

$8,000 – $20,000per project

Projects with high load, payments, smart contracts, subscriptions, balances, or complex business logic.

Long-term development / infrastructure

$20,000+and up

Multi-phase projects with custom architecture, scaling, security, and high load.

Business / asset tokenization / investment models

$10,000 – $25,000per phase

Tokenization of companies, equipment, infrastructure, and business equity. Architecture, smart contracts, backend, investor logic, and Web3 platform integrations.

The exact budget depends on the task. A short conversation is usually enough for us to give you a cost range and options.

Describe your project — we'll give you an honest budget range.

Example projects

A few of the problems clients have brought us. No company names — real outcomes.

Payment system with balances and subscriptions

Backend service with transaction accounting, pricing plans, subscriptions, and an API for external services.

The system runs under load and powers a commercial product.

Telegram service with payments and access control

Bot, backend, database, billing, and a user dashboard with automated access delivery.

The service runs with no manual operations and serves users automatically.

Web3 project with smart contracts

Contracts, backend, blockchain integration, token distribution logic, and event handling.

Case Studies

Real problems —
real solutions

Three projects with a breakdown of architecture, configuration, and code. From smart contracts to infrastructure and SEO.

12 areas of work

Each one is an area where a client had already tried on their own — or with another team — and ran into real complexity.

01
Asset Tokenization and RWA
Real-world assets as digital tokens — done right, technically and legally
Learn more →
SituationYou own a real-world asset — real estate, business equity, receivables, revenue rights — and want to make it available to investors or plug it into DeFi. It's unclear how to do it correctly on the technical side without creating legal problems.

We design and build tokenization smart contracts: token structure, ownership rights logic, payout mechanics, and investor verification integration. Technical documentation your lawyer will understand and be able to formalize correctly.

This is for you if
You want to raise capital through tokens but don't know how to implement it in a technically safe way
You need to split an asset into shares with automated income distribution
You're already working with lawyers on the structure — but have no technical team to turn it into a working contract
ResultA working smart contract with a security audit and documentation you can show to investors and regulators.
02
Smart Contract Development and Audits — Web3 / DeFi / Solidity
Secure, signed code — not a GitHub template
Learn more →
SituationYou need a smart contract for non-standard business logic — or an existing contract has to be verified before deploying to mainnet with real funds. The cost of a mistake here is irreversible loss of funds.

We build smart contracts for specific logic: DeFi protocols, vesting, governance, custom tokens. We run audits — including flash loan attacks, cross-contract interactions, and economic exploits that automated tools miss. Every audit report is signed with the company's name.

This is for you if
You need a contract for logic that no public template covers
You're preparing for a mainnet deployment and want an independent security review
The protocol is live, but after an incident in the industry you need a re-audit
ResultA contract that passed an audit with a signed report — investors and users can see that security was verified, not just claimed.
03
High-Load Systems and Scalable Architecture
Backend built for load, microservices, architecture audits, refactoring
SituationThe system works but can't keep up with growth — or you need a backend designed for serious load from day one. A conventional architecture no longer fits.

We design and build systems for high load: microservices, queues, caching, horizontal scaling. We audit code and architecture — finding bottlenecks before they turn into incidents.

This is for you if
The service slows down under load and nobody knows why
You need an architecture that survives 10–100x growth without a rewrite
You want a code audit before scaling or raising investment
ResultThe system holds the load, the team understands the architecture, and bottlenecks are eliminated before they became a problem.
04
SaaS, CRM, ERP and Document Workflow Systems
Internal tools, record-keeping systems, turnkey document generation
Learn more →
SituationYou need an internal system — record keeping, CRM, document workflow, report generation — that off-the-shelf products don't cover. Or your current SaaS doesn't scale to your actual business process.

We build SaaS products, CRMs, and ERPs around specific business processes, plus record-keeping and document workflow systems. Including automated PDF generation from templates — quotes, contracts, invoices — with the right formatting and your brand style.

This is for you if
Off-the-shelf CRMs and ERPs don't fit your logic, so the team lives in spreadsheets
Managers spend hours producing documents that differ only in the data
You need an internal service that integrates with your existing systems
ResultA system built around your logic — not an adaptation of someone else's template, but a tool that works the way you need.
05
Crypto Payment Integration and Crypto Acquiring
Accept USDT, BTC, TRX — your own node, no middleman
SituationYou want to accept crypto without relying on someone else's widget. Or standard providers in your region are unavailable or unreliable.

Your own nodes, transaction processing, payment reconciliation, integration into your product. Full control over funds. Works even in jurisdictions where Stripe and Coinbase are unavailable.

This is for you if
Standard processors don't work in your country or niche
You want control over funds with no third-party dependency
You need infrastructure isolation for security reasons
ResultAn independent payment system with no middleman fees and no risk of frozen funds.
06
Payment Gateway and Billing Development
Fiat + crypto, cards, fallback providers — one interface
Learn more →
SituationYou depend on a single provider — and when it goes down, the business stops receiving payments. Or you want to accept fiat and crypto without maintaining several separate integrations.

A single payment layer on top of multiple providers — cards, bank transfers (ACH / SEPA), crypto. One API for your product, automatic failover, billing with subscriptions and balances, unified analytics.

This is for you if
One provider is occasionally down and you lose payments
You need billing with subscriptions, plans, and balance accounting
You want to accept crypto without a separate complex integration
ResultPayments don't get lost when a provider fails — customers can always find a convenient way to pay.
07
Web Scraping and Data Collection Systems
Data collection without an official API — with change history
SituationYou need data from a platform that doesn't expose it through an official API. Right now it's collected by hand — or not at all.

A data collection system resilient to changes on the platform side — with deduplication, change history, and an API for accessing the results.

This is for you if
You need to track competitors or publications at scale
Change history matters, not just the current snapshot
Manual collection takes too much of the team's time
ResultA structured stream of up-to-date data — the team spends its time on analysis, not collection.
08
Webhook and API Integration Development
Guaranteed event delivery between systems
SituationSeveral systems need to know about the same event — a payment, a status change, a request. Sometimes something doesn't arrive, and you find out from the customer.

Infrastructure with delivery guarantees: queues, retries on failure, duplicate protection, a full log of every event, and alerts when something doesn't get through.

This is for you if
Payments or statuses sometimes don't arrive and have to be checked by hand
Several systems must react to the same event in sync
A lost event means financial or reputational damage
ResultEvery event reaches every recipient — you're the first to know when something goes wrong, not your customer.
09
Monitoring and Automation Systems
Automatic reaction to events 24/7 — no manual oversight
SituationYou need to know about an event immediately — a transaction, a status change, a user action — and you need the system to react on its own. Right now it's checked manually, or with a delay.

A system that continuously watches events, instantly filters the ones that matter, and triggers an automatic action — a notification, a transaction, a webhook. Runs 24/7.

This is for you if
A missed event means lost money or a critical failure
Someone on the team checks this manually on a regular basis
Event volume is growing and manual checks can't keep up
ResultThe system reacts in seconds, misses nothing, and needs no human in the loop.
10
Telegram Service with Payments and Subscriptions
A full product — not a template bot
SituationYou don't need a bot that answers commands — you need a tool your customers pay through, get access with, and use for work. No-code builders don't give you the flexibility.

A bot with subscription and payment logic, state management, third-party API integrations, and infrastructure that holds the load. A product built around your business logic.

This is for you if
You want to monetize a Telegram audience without an external website
You need integrations with APIs that behave unreliably
You've tried a bot builder — it wasn't flexible enough
ResultA finished product with payments, user history, and room to grow without a rewrite.
11
Refactoring, Architecture Redesign and Migration
Code audits, technical debt, migration with zero downtime
SituationYou need to move a live product or redesign its architecture — without losing data and without stopping the service. Or technical debt has piled up and is holding development back.

Technical audit of code and architecture, refactoring without stopping the project, and step-by-step migration to a new stack or infrastructure with validation at every step.

This is for you if
Development has slowed down because of technical debt and legacy code
You need to change the stack or hosting but can't stop the service
You want a code audit before scaling or a deal
ResultThe system runs faster, the code makes sense to the team, and the migration completes with no data loss and no downtime.
12
API Protection, Anti-Fraud and Abuse Control
Rate limiting, fingerprinting, protection from scraping and bots
SituationYour product is being used in ways it wasn't meant to be — data scraping, metric manipulation, bypassing limits. Simple blocking doesn't help.

Multi-layered protection: behavioral request analysis, fingerprinting, dynamic limits, shadow-ban logic. Blocks abuse without affecting real users.

This is for you if
Competitors scrape your prices or catalog
Bots generate fake activity that pollutes your metrics
Simple rate limits get bypassed within minutes
ResultProtection that works against real attacks — legitimate users never notice it.
