Technologies I work with

React

React is the foundation of most interfaces I build, from real-time dashboards to consumer apps with swipe gestures and chat.

7 projects

Next.js

Next.js is my default for web products that need to be fast and found on search engines. I have used it for e-learning, fintech, AI SaaS and paid content platforms.

4 projects

TypeScript

I write frontends and JavaScript backends in TypeScript so mistakes surface in the editor instead of in production.

3 projects

Django

Django is the backend I have used most, across e-learning, fintech, social and mobile products. Clients on Fiverr have specifically mentioned my Python and Django work.

5 projects

Python & FastAPI

Python is my main backend language. I use Django for full-featured products and FastAPI for lean, typed APIs and AI workloads like theMixtr.

6 projects

Node.js

I use Node.js when a team is JavaScript-first or a service is mostly real-time I/O. On IoCharts I co-developed the data ingestion engine in a Node.js codebase.

1 project

Go

I use Go for backend services where performance and simple deployment matter more than framework convenience.

PostgreSQL

PostgreSQL is the database behind most of my products, from stock market data to subscriptions and social feeds.

5 projects

Flutter

I build cross-platform mobile apps in Flutter, together with the Django backends they talk to.

2 projects

Supabase

Supabase powers myigirlfriend, my AI companion app. It gives a product authentication, a Postgres database and storage without running servers.

1 project

Cloudflare Workers

ChefJRP runs on Cloudflare Workers with a D1 database, so pages and payments respond quickly wherever its users are.

1 project

AWS

I have deployed and managed products on AWS, including the Sprachenzentrum e-learning platform and the Udictio social platform.
