What I'm looking for

I’m looking for a team where I can build full-stack products and data/AI systems with clean architecture, strong engineering practices, and real ownership. I want to ship reliable features, mentor others, and grow in high-throughput and GenAI integration.

I’m a Full Stack Software Engineer with 3+ years of experience building production-grade web applications, high-throughput data pipelines, and AI-powered systems. I enjoy clean architecture and clean code—especially when it comes to automation and shipping reliable features that users can trust.

Most recently at Apptec Services GmbH, I’ve delivered enterprise UI/UX improvements, built backend features in PHP and Node.js, modernized legacy PHP/C++ codebases for stability and scalability, and contributed to iOS features using Swift and Objective-C. Earlier, as a Data Engineer at Vitus Commodities, I built 100+ automated ingestion microservices (99.9% availability), led a migration that cut deployment time by 40%, and created logging/monitoring for high-stakes trading data—plus I’ve built multiple AI/RAG projects and real-time ETL systems end-to-end.
