Hire a React developer: work directly with a senior specialist
Not a marketplace, not an agency. You work directly with me, Manuel Coffin. I scope your project, write your code, and ship your product.
Senior React, Next.js and TypeScript · Direct collaboration · Europe, fully remote
What I build with React
React projects end to end, from SaaS front-ends to business dashboards.
Every project is built in TypeScript by default. I integrate REST APIs and the third-party services you already use (Stripe, Auth0, Clerk, Supabase).
Why hire me directly instead of going through an agency
You talk to the person writing the code
No account manager relaying your feedback through a chain of people who weren't on the call.
Senior-level work on every line
No bait-and-switch: agencies pitch a senior, then assign a junior. With me, there's no team to hide behind.
Faster feedback loops
Async-first by default. You get answers in hours, not days filtered through a project manager.
Transparent pricing
No agency markup, no coordination fees. What I quote is what you pay.
Flexible engagement
Sprint-based for ongoing product work, or fixed-price for a defined scope. You pick what fits.
Product sense, not just code
I'm not just a developer, I'm a product engineer. I've launched several SaaS products myself and currently work as CTO of a marketplace. I think in terms of product and business, not only technical decisions.
The result: less overhead, faster iteration, and a codebase you actually understand, because the person who built it can explain every decision directly.
How we work together
Discovery call (30 min, free)
We talk through scope, your current stack, and timeline. No sales pitch, just a technical conversation to see if we're a fit.
Proposal
I send a written proposal within 48 hours: fixed price or day rate, clear deliverables, milestones. No ambiguity.
Build
Weekly demos so you see progress early. Async updates. You own the repository from day one, no lock-in.

Clean, documented code. A walkthrough of the architecture, and optional ongoing support after launch.

What the founders I've worked with say
Before working with Manuel, our main challenge was to quickly build a functional and reliable MVP for Tobalgo. We needed a robust, scalable solution capable of validating our concept on the market without wasting time or budget.
Thanks to his expertise and commitment, we launched a working MVP that met our technical and functional expectations. The product allowed us to effectively test our market, attract our first users, and lay the foundations for future growth.
I especially appreciated his professionalism, his ability to quickly understand our needs, and his responsiveness to unexpected challenges. His clear and regular communication made the collaboration smooth and enjoyable. He managed to combine technical rigor with pragmatism, which was a real asset.
I recommend his services to any project owner or startup looking to develop an MVP quickly, with a reliable, agile, and genuinely human technical partner! His support is particularly suited to entrepreneurs who want to turn their ideas into a concrete product while keeping costs and timelines under control.
Thank you again for this successful first step — we truly can't wait to continue the Tobalgo adventure with you!

Co-founder at Tobalgo
We brought Manuel on for a key project, and it was a real pleasure working with him. He has deep knowledge of Next.js, Supabase, and Stripe, and delivered a clean, reliable, and well-thought-out solution. Professional, responsive, and a great person to work with day-to-day — I recommend him without hesitation.

Chief Engineer at Magic LEMP
Manuel did a very good job in creating our website from start to finish - from discussing the design and content of it, to assist with technical issues when we were launching the site.
We always had good communication throughout the working process where we first met in person to discuss the project, later had meetings online, and used phone or whatsapp for quick solutions which really helped alot.
The website turned out very profesional and we were happy with the design!

Sales and Marketing Manager at MbestCare
We hired Manuel to develop the TAFF! web application: a matchmaking platform with notifications and Stripe integration. As a young startup with no technical skills in-house, this was a key challenge for us.
We had obtained several quotes beforehand, but they were either too expensive or incompatible with our time constraints during the launch phase. Manuel stood out with a clear proposal: an MVP delivered in 14 days for 5,000 euros.
The collaboration was smooth from start to finish. Manuel was able to explain technical topics clearly, and was responsive and available at every step.
The delivered MVP fully meets our expectations: all requested features are operational. Manuel didn't stop at delivery and supported us for an additional month to fine-tune and stabilize the product.
Our first users praised the tool for being clear and easy to use.
We won't hesitate to work with Manuel again for future developments. We recommend Manuel for projects requiring fast execution, clear communication, and cost control — especially for teams without a technical profile.
Marion Basma
Co-founder at TAFF!
Working with Manuel on the TAFF! web app was a pleasure.
The result speaks for itself — a solid web app that matches our vision exactly. I recommend Manuel without hesitation to anyone looking for a reliable, dedicated developer who takes ownership of a project as if it were his own.
Thank you!
