I'm a Senior Software Engineer specialized in backend and infrastructure development with C#, Go and Python. I have a track record of building scalable and distributed systems in SaaS and Fintech, but my real passion lies in automation, observability, and making dev-life easier through better processes.
Most recently worked as an emerging products engineer, transforming AI technologies developed by research teams into MVPs and client-ready solutions. Involved in the full product validation cycle, including engineering and integration, client deployment, real-world testing, and feedback collection to assess technical and commercial viability.
