Rémi Blin
Freelance Software Developer
- Available for freelance
- 10+ yrs experience
- Tech-agnostic
- AI-integrated process
Freelance developer with a decade of shipping — from a quick proof of concept to an MVP, all the way to a production-ready platform.
Ten years of building software across Fintech, Edtech, Gaming, Web3 and MedTech, deliberately tech-agnostic: I pick the stack a problem calls for and lean on the fundamentals that outlast it. AI is fully wired into my delivery process — research, prototyping, testing — so ideas become shippable product faster.
Services
What I can take off your plate.
Software, end to end
Proof of concept
An idea to validate before betting a real budget on it
- a clickable product, not slides
- tested against real constraints
- a clear go / no-go signal
A working demo in days, AI-accelerated
MVP
A first version your users can actually adopt
- scope cut to what matters
- production-grade from day one
- live in weeks, not quarters
Scoped, built and shipped end to end
Production
A platform that has to hold real load and keep evolving
- performance and reliability
- a clean, documented codebase
- a team can take over anytime
Hardened, maintainable, ready to scale
Migration
A WordPress or shared-hosting site holding your business back
- content and SEO carried over
- speed you can measure
- no plugins, no lock-in
Rebuilt as a fast custom platform you fully own
Team reinforcement
A senior hand inside your existing product team
- productive from week one
- your stack, your workflow
- code that outlives the mission
Embedded, autonomous, delivery-focused
Capabilities
Tech-agnostic by design — the stack is a choice, not an identity.
AI-augmented delivery
Product
Frontend engineering
Fast, accessible, responsive interfaces for web and mobile.
Product design
Flows, design systems and clickable prototypes — from fuzzy idea to interface.
APIs & Data
APIs & services
Robust backends: clean contracts, integrations, authentication, background jobs.
Data & storage
Modeling, migrations and queries — data that stays consistent under load.
Delivery & Ops
Code & collaboration
Repositories, branching strategies, reviews and CI/CD pipelines a team can rely on.
Production & operations
Deployment, monitoring, performance and incident response — I run what I ship.
AI wired into design, code and review — moving faster without lowering the bar.
Experience
A decade of shipping, most recent first.
