A software engineer with a spark in the eyes. I like to build the best things in the world.

A hands-on Software Architect and Researcher. Deep knowledge in high-performance Java/Kotlin, distributed Big Data systems architecture, and their reliability. AI system development & integration of AI with external knowledge & tools. I like to find the most effective and simple solutions to complex problems and deliver results as soon as possible. Over 25 years of experience developing popular, high-load projects from scratch. Acted as a Lead Software Engineer, Team Lead, Founder, or sole full-stack developer on most projects. I know how to design and build complex, scalable, and reliable systems — and I've done so consistently.
