Gaëtan Masson

From idea to production product. 22 years of coding, 12 years of web products.

Senior full-stack web developer, I help founders and early-stage teams build solid web products, quickly, without over-engineering.

I am not a mere executor: I understand the product before thinking about the technology. I challenge the scope, I simplify, I prioritize, then I deliver a first version that your users can actually use.

My typical missions:

✔ MVP Development from A to Z: from idea to production: scope definition, development, deployment, iterations.

✔ Audit and takeover of prototypes created with AI: have you built a prototype with Lovable, Bolt, Cursor, or Claude? I audit it on a flat fee basis: honest assessment, identified risks, prioritized action plan. Then, you are free: you execute the plan with me, with another developer, or in stages according to your budget. You keep the speed of vibe coding, you gain the solidity of a real product.

✔ Evolution of existing products: new features, refactoring, technical debt reduction, scaling.

How I work:

→ An initial discussion to understand your project and frankly tell you if it's viable

→ A clear and prioritized scope before writing any line of code

→ Frequent deliveries: you see the product progressing every week

→ Simple communication, without jargon — I talk product with you, not tech

Main stack: Ruby on Rails, JavaScript, TypeScript, React, Next.js, PostgreSQL, Tailwind CSS.

I've been coding for over 20 years, including 12 building and running web applications in production for startups and scale-ups.
