Solidity & Web3 development for DeFi and protocol teams

I design and build smart contracts, DeFi protocols, and Web3 tooling for teams that care about security, clarity, and maintainability.

As a freelance Solidity developer, I've worked on staking systems, auction mechanisms, DeFi strategies, liquidity tooling, and automation around Uniswap-like protocols. I help you go from idea and spec to production-ready contracts and dApps.

What I build

I focus on practical Web3 systems that can actually be deployed and maintained, not just proof-of-concept contracts. Typical work includes:

Smart contracts – staking contracts, vesting, auctions, token distributions, governance modules and on-chain accounting.
DeFi tooling & protocols – strategies around AMMs, liquidity management, fee accounting, and protocol integrations.
Trading & liquidity automation – bots and on-chain logic for rebalancing liquidity, managing positions or reacting to on-chain events.
dApp backends – backend services and APIs that talk to contracts, index events and power dashboards or frontends.
Integrations – connecting contracts with oracles, relayers, keepers, or off-chain services that need to react to on-chain state.

When to work with a freelance Solidity developer

Bringing in a Solidity & Web3 engineer makes sense when:

You have a concrete protocol or smart contract idea but no spec.
You need a developer who understands both on-chain logic and the surrounding backend.
You want to prototype quickly, but with production and audits in mind from day one.
You already have contracts and want to extend, refactor or document them properly.

How I work

Requirements & spec – we translate your idea into clear requirements, edge cases and constraints.
Design – contract architecture, roles, storage layout, upgradeability decisions and interaction patterns.
Implementation – clean Solidity code, using proven patterns and libraries where possible.
Testing – unit and integration tests (e.g. Foundry / Hardhat), plus simulations where helpful.
Handover – documentation, deployment scripts and support around audits or launch.

Need help with a smart contract or Web3 project?

Whether it's a new protocol, a staking or rewards system, or automation around existing DeFi infrastructure, I can help you scope, design and implement it.
