Our expertise

The tools we build and ship with every day.

Software

  • React
  • Next.js
  • Node.js
  • React Native

Web, iOS and Android apps with the backends and cloud setup behind them.

Web3

  • Solidity
  • Foundry
  • Hardhat
  • Any EVM chain

Ethereum, Arbitrum, Base, Optimism, Polygon, BNB Chain and every other EVM-compatible network.

What we build

Two practices. One codebase mindset.

Most products need both a polished app and dependable infrastructure underneath. We cover the whole stack, so the frontend, backend and contracts are designed together.

Software development

01

Custom applications built to be maintained, not just launched. Clean architecture, tests and documentation your team can take over.

  • Web applicationsSaaS products, dashboards and customer portals
  • Mobile appsiOS and Android, native or cross-platform
  • APIs & backendsServices, data models and third-party integrations
  • Cloud & DevOpsCI/CD, infrastructure as code, monitoring

Blockchain & Web3

02

On-chain systems where a bug costs real money. We write contracts defensively and test them as if an attacker is reading every line.

  • Smart contractsSolidity on Ethereum and any EVM chain, upgradeable where it makes sense
  • DeFi protocolsVaults, AMMs, staking and lending logic
  • Testing & audit readinessFuzzing, invariant tests and review-ready documentation
  • dApps & walletsFrontends, wallet connection and on-chain data indexing

Why teams pick us

Fewer hand-offs, fewer surprises.

The whole stack, one team

No juggling an app agency and a separate blockchain shop. The people who write your contracts also build the screens that call them.

Security is the default

Threat modelling up front, tests before features, and code that's ready for an external audit long before one is booked.

Working software every week

You see progress in a live build, not a status report. Priorities can shift without the project going off the rails.

  1. Step 1DiscoverGoals, users, constraints and a scoped plan with a clear first milestone.
  2. Step 2DesignArchitecture, data model, contracts and interface, reviewed together.
  3. Step 3BuildWeekly increments with tests, code review and a live staging environment.
  4. Step 4Launch & supportProduction release, monitoring and ongoing maintenance as you grow.
