Philosophy & Background

About Dominik

Senior Software Engineer combining deep backend craftsmanship with startup agility and product thinking.

I am an engineer who thinks like a product builder. Over the last 9+ years, I've worked across fast-paced startup environments and high-standard engineering agencies like Infinum and IN2 Group, owning systems from day-zero whiteboard architecture all the way into production scale.

My core sweet spot is distributed backend engineering — crafting resilient APIs with C#/.NET, designing scalable data models in PostgreSQL and Redis, and architecting event-driven cloud systems on AWS and Azure with modular monoliths and microservices.

Beyond code architecture, what drives me most is user impact. I believe true engineering excellence isn't just about elegant abstractions; it's about solving real problems, delivering value fast, and measuring success by products people rely on every single day — which led me to launch platforms like Kvizalica and collaborate on creator platforms like Subs.
