Who I am

I am a 20 year old computer science student from Germany, currently living in Munich. Over the past years I have built skills in several fields of development with a focus on web and app development. I have worked on several projects, some of which are displayed below.

Since August 2026 I have been working part-time as a full stack developer at Lively Apps in Munich. Before that, I worked as a full stack developer at upmesh from November 2021 to August 2026, where I mainly worked on a mobile app built with react-native alongside school and university.

Since autumn 2025, I have been studying computer science (B.Sc.) at the Technical University of Munich. In my free time, I keep working on hobby projects like the ones below.

What I have worked on

Here are some projects I have worked on over the past years

MotoMeet

A platform for motorcyclists that allows them to meet other riders and plan rides or meetups together. MotoMeet is built with Expo and Supabase and is my biggest side project so far.

Lolili

An app for your own bookshelf: scan books by barcode, sort them into colour-coded categories and keep track of who has borrowed what. Lolili is built with SwiftUI and SwiftData for iPhone and iPad.

MyGainplan

A social media-based fitness app that helps users manage and update their workout plans. MyGainplan is built with react-native, MySQL, node.js, and express.js.

Movie Match

A web app that helps you and your partner to find a movie you can watch on your next movie night based on your preferences. Movie Match is built with next.js and TypeScript and uses the TMDb API to fetch movie data.

Animated 3D Solar System

An animated 3D solar system created using Three.js that visualises the planets rotating speed around the sun and their own axis. I have built this project during an internship at a web development company.

Playground

This is a page where I showcase this I've tried out and minigames I have built that have faced me with all kinds of new and interesting challenges

What tech stack I use

My current tech stack consists of next.js and react-native for the frontend and node.js with express.js for the backend. I use MySQL for my databases and TypeScript as my preferred programming language. To store and host my projects, I use GitHub and Docker.
