About
Full-Stack Developer based in Berlin, building reliable APIs, fintech systems, cloud infrastructure, and automation.
IHK Certified IT Specialist with hands-on experience in Scrum teams. I focus on backend architecture — FastAPI services, PostgreSQL schema design, AWS deployments (EC2, S3, RDS), and Docker-based containerization.
My work includes CI/CD pipelines, Linux server administration, and third-party API integrations. I'm comfortable working independently on full-scope projects or alongside product and frontend teams.

What I Build & Deliver
Here's what I actually do, from writing the first API endpoint to keeping the server running at midnight.
Database Architecture
PostgreSQL schema design done right from the start. I handle migrations with Alembic, keep queries fast, and use SQLAlchemy where it makes sense.
PostgreSQLSQLAlchemyAlembic Migrations
Cloud & Infrastructure
AWS setup that's actually documented and reproducible. EC2, S3, RDS, IAM, Docker. No black-box configs that only one person understands.

Workflow Automation
Tired of doing the same thing manually every week? I build n8n workflows that connect your APIs, databases, and tools, and keep running without babysitting.
n8nWebhooksAPI Integration
Full-Stack Web Apps
FastAPI in the back, React/Next.js in the front, wired together cleanly. I can take a project from blank repo to deployed and working.

WordPress & IT Support
When a client's WordPress site gets hacked or goes down, I fix it. Security hardening, performance cleanup, and recovery. Done it for corporate clients.

DevOps & Linux
Linux server admin, Bash scripting, automated deployments. I'm comfortable on the command line and can set up CI/CD pipelines that actually save time.

FinTech & Trading Tools
Real-time dashboards, arbitrage engines, and price monitoring systems built for speed. WebSocket-driven data pipelines, live P&L calculations, and exchange API integrations.

Things I've actually delivered in production
Real outcomes from production environments, not side projects or tutorials:
- Reduced page load time from 5s to <1s by profiling the full request chain and eliminating a backend bottleneck (query optimization, caching layer, and asset-level improvements)
- Recovered a compromised WordPress corporate site the same day and hardened the environment (permission cleanup, patching, WAF rules, login security hardening)
- Automated a manual reporting workflow, reducing ~3+ hours of weekly operational work through scheduled jobs and structured data aggregation
- Designed, built, and deployed a production backend using FastAPI + PostgreSQL on AWS (EC2 + RDS), operating with zero downtime since launch
- Built and deployed production-ready web pages and internal dashboards with a focus on performance, SEO structure, and responsive UI
- Developed automation workflows using n8n, integrating multiple APIs and internal systems to eliminate repetitive manual operations and streamline processes
