Bruno Stacheski

Senior Software Engineer | Product Engineering | AI Engineering

Berlin, Germany

I build software that solves real-world problems at scale. With roots in robotics and electrical engineering, I bridge deep technical architecture and seamless user experiences — taking end-to-end ownership of the product lifecycle, from initial design and TDD to infrastructure provisioning. From KYC solutions for over a million users in fintech to e-learning platforms serving millions of learners, I thrive where moving fast must be balanced with building right. This site is where I write about what I learn.
