About Me
I’m a Senior Fullstack Engineer and Technical Lead based in Berlin, with over 15 years of experience building scalable, high-performance web applications and leading engineering teams.
My expertise lies in React, Next.js, Node.js, and AWS delivering clean, maintainable code and user-centered design systems across industries like fintech, classifieds, and e-commerce.
Currently, I work at a fast-growing fintech startup GoDiligent, An AI-driven platform built to analyze complex customer data and streamline due diligence for banks and fintech firms. I contributed to the integration of AI agents into compliance pipelines, developed interfaces to visualize risk insights, and ensured the system provides full auditability for enterprise-ready deployments.
I believe in mentoring, continuous learning, and building bridges between design, product, and engineering.
When I’m not coding, you’ll find me traveling, behind the lens doing photography, deep into a good book, or enjoying a strategic game of chess.
