DevSecOps Engineer & Cloud Architect with a background as a startup founder/manager. I now work as an independent consultant through LiveSystems s.r.o., serving multiple clients across cloud infrastructure and security, while building Sencai - a B2B FinOps SaaS platform for EU-sovereign cloud infrastructure, targeting the SMB and mid-market segment across CEE.

I've spent years building and scaling startups before moving deeper into hands-on DevSecOps and cloud architecture. That founder background shapes how I work now - I combine infrastructure engineering with product and business thinking, which is also why I'm building Sencai: a FinOps platform born out of real pain points from running cloud costs across multiple ventures and clients.
Today I split my time between consulting for external clients on cloud/security infrastructure, and building Sencai from the ground up.

Building Sencai as the FinOps platform I wish existed when running cloud costs across multiple startups and client environments - with a strong focus on European data sovereignty as an alternative to non-EU hyperscalers. Alongside that, I consult on infrastructure and security for a range of clients across the CEE region.
