From the first rough idea to the shipped application, I design and engineer the whole thing in TypeScript—web, mobile, backend, and the seams between them.
Selected work / 01—04
Four different problems. One consistent approach: understand the business, make the complex feel clear, and ship something sturdy.
A healthier screen-time loop: movement unlocks play. I helped turn a legacy app into a shippable cross-platform product, from core architecture to payments and publishing.
A field-ready PWA that makes live machine data understandable. The system was rebuilt from Laravel into a modular TypeScript architecture designed for real-time workloads.
A precise launch surface for a developer-focused product: clear hierarchy, confident technical language, and a frontend fast enough to stay out of the message’s way.
A polished showcase that helps a specialist business look established and easy to trust—without burying visitors in features or unnecessary interface patterns.
Ways I can help / 06
SaaS products, operational tools, admin platforms, and business logic built around the way your team actually works.
Distinctive, high-performing websites and landing pages that make the offer clear and the next step obvious.
One product, iOS and Android. Thoughtful mobile UX with the backend, payments, and release process handled.
Untangle fragile code, improve delivery speed, and move old systems toward a maintainable modern architecture.
Reliable APIs, background jobs, integrations, event pipelines, and system boundaries that can grow with the product.
Product-led storefronts and catalogs that balance editorial presentation with fast, frictionless buying.
How the work works
A practical five-part rhythm that keeps decisions visible and momentum honest.
We map the real problem, constraints, users, and what success needs to look like.
You get a clear scope, technical direction, milestones, and honest tradeoffs before build starts.
I work in visible increments, share progress weekly, and keep feedback close to the code.
The final stretch covers edge cases, performance, handoff, deployment, and a calm release.
After launch, I stay available for fixes, iteration, and the next useful version.
A little context
I’m Yousen, a full-stack engineer in Algeria. I started building with Arduino and PHP in high school; today I work primarily in TypeScript across product design, frontend, backend, and mobile.
My favorite projects have real operational weight—the app a team relies on, the modernization that unblocks a business, or the interface that makes a complicated system finally feel simple.
