I have been building for other people's businesses since 2017 — scoping directly with stakeholders across Europe, the USA and the Gulf, then shipping what they turned out to need rather than what the brief said on day one. Alongside that I went the other direction, down into systems fundamentals — the layer under the frameworks, in C and C++.
Sekera Group is how I broke into startups. I joined as its founding engineer intern and left as Founding Engineer / Team Lead, taking the SIEM platform from MVP to production inside fifteen banks and insurers — regulated environments where shipping means meeting the customer's constraints, not just passing your own tests — and growing the team from one engineer to eight.
That combination is the point. The hard part of deploying into someone else's environment is rarely the code: it is the discovery, the constraints nobody wrote down, and being able to drop to the layer where a thing is actually broken while the customer is watching. I prototype fast and make it provable — then work security-first, with code review, TDD and design patterns as defaults, not afterthoughts.
