About Bertrand

Hello, I am the developer you are missing. I master NodeJS, Go, Python, PHP and of course Typescript/Javascript.

I bring you my experience and knowledge acquired over my 20 years of career in the web development industry. I have worked on frontend issues for several years but my true area of expertise is backend development.

I will create and build for you a robust, scalable and inexpensive backend. I will support you to make your project a success. I have helped dozens of startups to launch, to create their architecture, to make platforms resilient and capable of handling high loads, but also to completely overhaul some pure player backends.

Creative, ingenious, rigorous, methodical and proactive, I am here to ensure your project runs perfectly. I am used to Agile methods, iteration and tight deadlines. I love challenges and solving problems.

I have supervised multiple developers in my roles as Lead Developer and my experience as CTO has allowed me to acquire the know-how to bring each project to completion.
