Full Stack Developer
Most websites go live. Yours should go to work
Frontend and backend: websites, web applications, iOS and Android apps, UI/UX design and technical SEO — designed, built and shipped end to end, on the same stack I run in production every day.
What I can build for you
One developer, full ownership — from the first sketch to a live, indexed, revenue-ready product.
- Business Websites A fast, professional site built to be found on Google and to turn visitors into inquiries.
- Web Applications Marketplaces, dashboards, booking and ordering systems — on the web and as iOS and Android apps.
- UI/UX Design & Mockups Wireframes and clickable prototypes, so you can test the product before it is built.
- Technical SEO Prerendering, structured data, Core Web Vitals and indexing that actually moves rankings.

Your project here
I'm taking on a limited number of new projects. If you need a website or application that has to work — and has to be found on Google — let's talk about it. The quote is free and honest.
Start a project →Want to see the code first?
Fair. Celina's source is public under an MIT licence — the whole production system, not a sample: TypeScript and React at the front, Node and Prisma behind it, Docker around it. Read how I structure something real before you spend anything.
Read the Celina source →A process with no surprises
You always know what happens next, what it costs, and when it ships.
Talk
A short call or WhatsApp chat about your goals. You get a fixed quote and a milestone plan within 48 hours — free, no obligation.
Agreement & design
Scope, price, milestones and timeline go into one document we both sign. Then wireframes and mockups, so you see exactly what will be built and approve it before development starts.
Build
Clean, secure code with weekly progress updates you can actually see — a live staging link, not status reports.
Launch & grow
Deployment, SEO indexing, and analytics on day one. You own the code, the domain, and the data — no lock-in.
The developer behind the work
I'm Shlomi Aflalo, a full stack developer based in Lisbon, Portugal, who ships complete products — frontend, backend, infrastructure and SEO. I've taken two systems from an empty repository to production, including a live consumer marketplace I still operate. When you hire me, you talk directly to the person writing your code.
Transparent packages & pricing
