Senior Full Stack Developer

I owned the development and delivery of AI-powered features across lemlist, covering product exploration, technical design, and production implementation.

I worked on lemAgent, building agentic workflows and capabilities that interact with product data and internal services. I designed MCP integrations and improved AI-agent security and reliability through automated evaluations and prompt-injection testing. I also built scalable backend systems using TypeScript, Node.js, MongoDB, Elasticsearch, Kafka, and SSE.

I managed a team of four developers and was responsible for software architecture design and implementation.

I introduced processes and tools to strengthen system stability and security, including robust CI/CD pipelines, internal engineering processes, and Kubernetes infrastructure. The stack included NestJS, React, PostgreSQL, InfluxDB, Kafka, GitHub, Docker, and Kubernetes.

I co-founded BetterCents, an automatic debt repayment platform in the UK, as part of a three-person founding team. The company scaled until its acquisition by ClearScore in August 2023.

I built the product technology from the ground up using Node.js and React. I delivered high-performance, highly available systems through strong CI/CD practices and robust AWS infrastructure, using NestJS, PostgreSQL, Redis, Docker, and GitLab.

I co-founded Ekoha to help entrepreneurs launch MVPs and scale their companies through a cash-and-equity partnership model. Over three years, we delivered web and mobile products for entrepreneurs in France and the United States, while also launching internal SaaS products used daily by thousands of users.

I led technology decisions and development across projects built with Sails.js, Vue.js, MongoDB, Elixir/Phoenix, React, PostgreSQL, Redis, React Native, Node.js, Express, NestJS, Ionic, AngularJS, TypeScript, RxJS, and Akita.

I started the frontend development for the new Vulog Platform as its sole frontend developer, building the initial foundations in close collaboration with backend and product teams.

I worked full time for six months and then part time through the end of the contract. I helped grow a frontend team of seven developers and worked with React, Storybook, React Admin, Redux Thunk, Redux Saga, and Material-UI.

I founded Mlappz to help startups and small businesses deliver projects quickly. I developed MVPs from scratch for clients, including the Friool platform and an online real-estate agency for Luxembourg.

The work included Ruby on Rails, MongoDB, jQuery, Stripe Connect, Mailgun, and Heroku. The real-estate platform included online PDF sale-agreement generation and history management, alongside property buying and selling workflows.

I led a web application project for Unilever using ASP.NET MVC and AngularJS. I also led a team of five developers building a cross-platform mobile application, initially with Ionic and AngularJS and later with Xamarin and C#.

I contributed to the design, backend, and mobile development of the application. I also developed a finance-simulation online game for a European Commission project and initiated a Horizon 2020 project using ASP.NET and Unity.

I joined Yieldify as the company's second developer during a period of rapid startup growth. I worked across multiple product areas and helped the team adapt quickly to evolving technical needs.

I developed and maintained a marketing web application in Ruby on Rails, created an HTML5 JavaScript game engine for branded voucher games, and built client dashboards with AngularJS, D3.js, and Highcharts. The resulting application was viewed millions of times daily across e-commerce websites.

Computer Science bachelor's degree completed in Marseille, France.

French secondary-school diploma, equivalent to a BTEC National Diploma in electrical engineering, completed in Gignac-la-Nerthe, France.
