Maybe you already have a product. It's live, it looks okay, but something is off. Most web products have the same silent problems. Pages Google will never index because they were never properly linked. API calls firing on every keystroke draining your quota and your bill. A user flow that made sense to the developer but confuses every actual user who lands on it. A mobile layout that breaks at 768px and nobody noticed because the developer only tested on their own screen.
You have an idea. Maybe it is quite clear in your head, the product, the users, what problem it solves. What is not clear is how to turn that into something real that works, scales and doesn't need to be rebuilt every time you want to add a feature.
Either way, you're in the right place.
I'm a full-stack developer with a background in data systems and spatial analytics. When your product involves data, comparisons, predictions, maps or dashboards, I don't just display it. I architect it so it stays fast, readable and useful as it grows.
I build full-stack web applications for founders and teams who need more than a developer. They need someone who thinks about the product the way they do, who asks the right questions before writing any code, and who delivers something that real users can actually use on day one.
I have a background in data systems and spatial analytics which means I think in structures. How data flows through a product, how it gets stored, how it gets surfaced to a user at the right moment in the right format. That mindset shapes everything I build.
What I build for clients:
✅ SaaS MVPs built to launch, not just to demo. Clean architecture from day one so you're not rewriting everything six months later
✅ Data dashboards and analytics platforms where the goal is not just to show numbers but to help someone make a decision faster
✅ AI powered web applications with LLM integrations, smart search, recommendation logic and automated workflows built into the product experience
✅ Niche web apps like directories, prediction tools, comparison sites and booking systems
✅ Location aware applications with interactive maps, geographic filtering and spatial data pipelines
My stack:
⚡ Frontend: React, Next.js, TypeScript, Tailwind CSS
⚡ Backend and Database: Supabase, PostgreSQL, PostGIS, REST APIs
⚡ Maps and Spatial: Mapbox GL JS, PostGIS
⚡ AI Integrations: OpenAI API, LLM powered features, intelligent automation
How I work:
🔹 I work in milestones. You always know what is being built, you see it working before we move forward, and you are never left wondering where your money went
🔹 I communicate at every stage. If something needs a decision from you, I bring it to you clearly with context, not with jargon
🔹 I think about your users before I think about your code. A feature that confuses people is a feature that failed
I use AI tools (NOT VIBE CODING) to move fast but I own everything that ships. Check my portfolio to see what I have built.
