Description

Fullstack JavaScript/TypeScript developer with 20 years of experience, I join product teams to deliver robust, well-tested, and maintainable features in the long term.

At Indy (fintech scale-up), I helped grow the team from 5 to 40 developers while maintaining multiple deployments per day — thanks to the implementation of a monorepo, trunk-based development, and a solid TDD culture. I also designed support solutions saving hundreds of hours per month, and led the migration of the application from Meteor to Fastify.

Beyond code, I place great importance on team skill development: pair programming, code reviews, training in best practices. I leave teams better than I found them.

My main stack is Node.js/TypeScript on the backend, Vue.js and React on the frontend — but I am perfectly comfortable adapting to other technical environments: Python, Ruby, Go, or others.

Main Stack: Node.js · Vue.js · React · TypeScript · PostgreSQL · Docker · GitHub Actions · Kafka · Grafana
