Description

Protocol & Web3 Developer: Solidity, React, Next.js, The Graph

Developer with 8 years of experience, specializing in the design of complete onchain applications: smart contracts (Solidity, Foundry), Indexing, SDKs, and React/Next.js/TypeScript frontends. I work across the entire stack, from protocol design to mainnet deployment.

My background combines startups (Theodo, Sismo), freelancing (Peanut Protocol, Superfluid), and entrepreneurship. I have designed and delivered blockchain protocols in production, complete web applications, payment systems, and business dashboards.

Strengths:

• Smart contract architecture: proxies, factories, beacon upgrades, integration with other protocols

• Onchain Full-stack: from smart contract, backend, frontend, including SDK, MCP, etc.

• End-to-end autonomy, from technical scoping to production deployment

• Rigorous about code quality, pragmatic about deadlines

• Clear communication, accustomed to working with non-technical profiles

• Rapid skill acquisition on new environments and stacks

• Team and solo experience, comfortable with remote work

Stack: Solidity, Foundry, The Graph, React, TypeScript, Next.js, Node.js, PostgreSQL, Viem, Wagmi

Based in Toulouse, available remotely or hybrid. I am looking for assignments where I can quickly add value: protocol development, blockchain integration, MVPs, technical redesigns, or team augmentation.

We worked with Nezzar for a long-term agile project using React/TypeScript and Serverless technologies. Nezzar brought his expertise in React and delivered frontend features on time and to the quality standards the team had set. Nezzar also quickly acquired skills in backend and delivery methodologies (Scrum, Git Flow, etc.). Nezzar is focused, attentive, and very humble. We would undoubtedly call on him again for future projects.
