Back to original languageAbout Tanguy
Hello 👋 My name is Tanguy Jacotot. Full-stack developer (Master's degree).
I spent three years in work-study programs. In parallel, I founded Promesia. I build useful software solutions: web and mobile applications, APIs, and automations.
We start by understanding the real problem, set simple milestones, and then move forward in visible increments. I enjoy working with teams of all sizes and keeping communication clear.
On the tech side🧑💻, I am versatile and curious, without tool dogma. My toolbox ranges from TypeScript, React, Next.js, and React Native or Vue to PHP with Laravel or Node.js with Nest or Express, including REST, GraphQL, PostgreSQL, MySQL, Docker, and careful CI/CD. If your environment is different, I adapt and document to bring everyone on board.
Curious to learn more? Send me a message.
