About Me

Building reliable platforms that scale

I’m a senior software engineer focused on designing backend systems and full‑stack products that are stable, secure, and easy to evolve. I partner closely with product and stakeholders to translate complex needs into clear technical direction.

Over the years I’ve led API architecture, performance tuning, and delivery of production services across Python ecosystems. I value pragmatic engineering, clean interfaces, and team alignment. I’m open to senior opportunities in Switzerland where I can help build dependable systems and mentor engineers.
