Our services

Web3 & blockchain

Wallets, smart contracts and on-chain data, wired into products people can actually use.

We connect chains to products: wallet and signature flows, smart-contract integration, indexers that turn on-chain events into queryable data, and exchange APIs scoped so that keys and custody stay out of our reach. The chain is an implementation detail — the product still has to feel obvious.

What you get

• —Wallet connection, signature and auth flows
• —Smart-contract integration and typed ABI clients
• —On-chain indexers and event pipelines
• —Exchange and custody API integrations
• —Permission scoping and key-handling review

Stack

• Go
• TypeScript
• Node.js
• PostgreSQL
• Exchange APIs

Startup architecture

The system design that decides whether year two is a rewrite or a release.

Most startup rewrites are paid for by decisions made in week two. We settle those first: where the service boundaries fall, how the data is modelled and migrated, what the infrastructure costs at ten times the traffic — and we write down why, so the next engineer inherits the reasoning and not just the code.

What you get

• —Domain and service boundaries
• —Data model and migration strategy
• —Infrastructure and deployment topology
• —Scaling path and cost envelope
• —Decision records for every hard call

Stack

• Microservices
• Docker
• CI/CD
• PostgreSQL
• Kafka

Real-time systems

WebSockets, Socket.IO, Server-Sent Events, queues and event streams that stay honest under load.

Live prices, live matches, live deliveries: when the number on screen is wrong for three seconds, the product is wrong. We build the transport, the fan-out and the recovery — backpressure, reconnects, replay after an outage — so the state a user sees is the state the system holds.

What you get

• —WebSocket and Socket.IO gateways
• —Server-Sent Events streams
• —Kafka topics, consumers and replay
• —BullMQ job and retry pipelines
• —Backpressure, reconnect and idempotency handling

Stack

• Go
• Node.js
• Socket.IO
• Kafka
• BullMQ
• Redis

Backend engineering

Go, Node.js and PHP services with the boring parts done properly.

APIs, workers and integrations built to be operated: real migrations, real observability, idempotent writes, and a test suite you can deploy on a Friday afternoon. Fifteen years of production has taught us exactly which shortcuts get billed back later, with interest.

What you get

• —REST and GraphQL APIs
• —Microservices and message contracts
• —PostgreSQL, MySQL and MongoDB schemas
• —Auth, billing and third-party integrations
• —Observability, alerting and runbooks

Stack

• Go
• Node.js
• PHP
• PostgreSQL
• MySQL
• MongoDB

Frontend engineering

React and Next.js interfaces on a real design system — typed, fast and accessible.

Interfaces built on tokens and components rather than one-off screens, typed end to end against the API, fast on a mid-range phone and accessible because it was built that way. This is where the small details live: loading states, empty states, focus rings, the wording of an error.

What you get

• —Next.js App Router applications
• —Design systems and component libraries
• —Real-time UI wired to live data
• —Core Web Vitals and performance budgets
• —WCAG 2.1 AA accessibility

Stack

• React
• Next.js
• TypeScript
• Tailwind CSS
• Framer Motion

AI-ready delivery

Every project handed over with the architecture, rules and skills an AI can work from.

We use AI every day and we hand it over. Each project ships with its architecture documented, plus rules and skills written for its exact stack — conventions, task recipes, a seeded local environment. Your team, and the AI they code with, keep shipping the day after we leave, without guessing at our intent.

What you get

• —Architecture and decision records
• —Agent rules and skills tuned to the project stack
• —Conventions, prompts and task recipes
• —Seeded local environment and fixtures
• —A handover walkthrough with your team

• Claude Code
• MCP
• Cursor
