Your backend is the foundation of everything.
And most of the time, it's also the thing
that breaks everything.
Slow endpoints. No auth. No validation.
Data just sitting there with no structure.
I build FastAPI backends that don't do that.
Clean REST APIs with PostgreSQL, JWT auth,
and proper migrations from day one — not
bolted on later when things start breaking.
Built a URL shortener API with GeoIP tracking,
rate limiting, and click analytics. Runs on a
VPS. Still running.
Built a crypto portfolio tracker with live
price feeds, P&L calculations, and full auth.
Also still running.
If you need a backend that actually holds up —
not just works in localhost — that's what I do.
Message me.

Playmaker Xpress – Full-Stack Fitness & Training Platform
I designed and developed Playmaker Xpress, a full-stack website for a personal training and athletic performance business.
I built the frontend using Next.js, React, and TypeScript, with FastAPI powering the backend and PostgreSQL for the database.
The platform provides a responsive, modern experience where clients can explore services including personal training, speed training, movement training, group fitness, and kickboxing fitness.
Tech Stack: Next.js • React • TypeScript • FastAPI • PostgreSQL
This project demonstrates my ability to build both the frontend and backend of a real-world web application, connect APIs to a database, and deploy a production-ready application.
I’m available for full-stack, React, Next.js, Python, and FastAPI development project
good work
Been playing around with 3D on the web and ended up building this.
The scene was made in Blender, characters with Tripo3D, and everything was brought together on the web with Three.js + Astra.
It’s also a live multiplayer experience, people can join the same space, walk around, talk to each other and just hang out together.

Redesigned Linea's home screen. The bit i care about most is the signals panel, the system watches every run and flags anything that looks wrong: "hallucination suspected", "tool error", last seen, how often. you catch it before a user does.
Each execution shows its cost. the support assistant's about a cent a run. Second shot is the canvas where the flows get built.
Is the home page enough at a glance, or would you pull executions higher?
