Here are some of my last client :

FANtium (8 mo) - Cut technical debt and modernised the Web3

stack : migrated from web3.js/ethers.js to Viem Wagmi and shipped

audited Solidity contracts. (Stack : React, Next.js, Typescript,

GraphQL, Vitest, Viem, Wagmi, Solidity, Foundry, Docker)

Mobula/Hexa (Riverflow) (7 mo) - Re-architected a monolithic

Express API into NestJS micro-services. Added Redis RabbitMQ for

real-time event handling. (Stack : React, Next.js, NestJS, Typescript,

Prisma, Redis, RabbitMQ, Web3.js, Docker)

BlackPool Finance (1 yr 7 mo in core team) - Led on-chain data

aggregation and developed ERC- 721 contracts. Ongoing app

maintenance and product consulting (Stack : Next.js, Typescript,

Solidity, Foundry)

Majora Finance (ex -Strateg Protocol) (3 mo) - Built a NestJS

blockchain listener that parses events (Stack : NestJS, Typescript).

I worked as a full stack developer on an international team for an insurtech company. The solution was composed of several websites and apps with a microservice architecture. The main stacked used was Angular (<2.0) for the front end and Asp .net core for the back end. Some websites were built using react js and nodeJs.

• Developed casino-platform features with ASP.NET MVC and front end layers in KnockoutJS and AngularJS 1/2 TypeScript.

• Maintained and extended back-end logic exposed through WCF services and REST APIs.

• Wrote and ran unit tests, integration tests, and SpecFlow acceptance tests to keep releases stable.
