Full-Stack Software Developer
Freelance and in-house
I build software from interface to infrastructure.
I build web apps, backend APIs and mobile apps. I also set up the servers they run on and publish them to the App Store and Google Play. One developer, from the first line of code to the live product.

Scroll downGrouped by the parts of a project I handle, not by logos. Each one lists what I deliver and the tools I use for it.
TypeScript / React / Next.js / Tailwind CSS
Websites, web apps and dashboards that work well on any screen size.
Laravel / PHP / MySQL / Redis
The backend behind the app: APIs, logins, databases and integrations.
React Native / Expo / Kotlin / Android Studio
iOS and Android apps with React Native and Expo, plus native Android in Kotlin when needed.
TypeScript / React
Desktop apps for teams that need software outside the browser.
Linux / Ubuntu / Nginx / Docker
The server side of shipping: Linux servers, Docker, Nginx, domains and SSL.
App Store Connect / Google Play Console / EAS / Gradle
Getting the app into the App Store and Google Play, and keeping it there.
Real products, built and shipped from start to finish: the app, the backend, the server and the store listing.
2024 – 2025
E-Commerce / Affiliate Platform
A mobile and web platform where people discover products and earn through affiliate links. I built the mobile apps, the web app, the backend and APIs behind them, and deployed everything to production.
Scope
2024
Data Analytics / Mapping / Government System
A system for managing crime records with analytics, interactive maps, hotspot views, forecasting and reports. Built so analysts can see clearly where and when incidents happen.
Scope
2025
Commerce / Operations
A mobile app that lets merchants run their business from one place: products, orders, inventory, ads and daily operations.

I can handle every step below, so nothing waits on another team. Keep scrolling to move through the pipeline.
The main tools are in large text. The smaller ones are the related skills I use with them. All of these have been used on real projects.
Many developers stop when the code is done. I keep going: I set up the server, build the release, publish to the stores, and fix what breaks after launch.
Not just the screen you see, but also the API behind it, the database, the server it runs on, and the app store it ships to.
I work as a freelance developer and, since July 2026, as a full-stack developer on a team. In both, the goal is the same: understand the whole system, build each part well, and stay until it is live and working.
