What I'm looking for

I'm open to remote opportunities, international teams, and freelance collaborations, especially in software engineering, cloud computing, financial technology, and applied AI.

At Trustly, I migrated a suite of on-premise microservices to AWS and contributed to moving an online payments platform from a legacy monolith to a microservices architecture.

Earlier at Trustly, I led a team of five engineers implementing Open Banking API integrations across multiple European banks. I also contributed hands-on through development, mentoring, and code reviews.

At Smart Consulting / BNP Paribas, I developed and maintained financial applications and supported critical banking systems. Across my banking work, I also developed and maintained enterprise systems using COBOL.

I'm currently expanding into full-stack development with React and Angular, and AI-powered applications using Python, LLMs, and RAG. I'm open to remote opportunities, international teams, and freelance collaborations.
