Portfolio: ali.champtech.dk/ I've been the technical co-founder behind four startups — Emploai, Clozio, StageHub, and DRIVN. That means I've built the full product each time: architecture, frontend, backend, billing, deployment, and everything in between. Most of my work is SaaS platforms and business tools, but I've shipped everything from mobile apps to enterprise systems with multi-tenant setups. 49+ projects delivered through my company ChampTech, most of them still running in production. I work in Next.js, React Native, TypeScript, Python, FastAPI, and PostgreSQL. I use OpenAI and AI integrations when they actually solve a problem, not just to add a buzzword to a landing page. If you need someone who can take your idea and turn it into a real product that works — not a prototype that falls apart when users show up — that's what I do.

Programming is both my hobby and my job, so I enjoy working on challenging projects. For the past 7 years I've been working as a software developer growing my skills increasingly. I've got plenty of experience in different fields and technologies. My key skills are: - JavaScript (browser based web app, server-side with NodeJS) - Native iOS apps - Browser extensions for Chrome, Firefox, Safari, Internet Explorer and EDGE - Amazon Web Services (EC2, Lambda) Also I have strong knowledges in: C++, network and socket programming (VPN, Proxy), multi-threading, WinAPI.
