Who Am I?

About Me

The success of a system is determined not only by the technology used, but also by an understanding of the business context, accurate planning, and the team's ability to execute solutions consistently and responsibly.

I am a technology professional with extensive experience in systems analysis, application development, and technical team leadership. I possess a strong background in translating business processes into scalable, structured, and maintainable digital solutions.

Experienced in managing end-to-end application lifecycles, from requirements analysis and system design, development coordination, quality assurance, and post-implementation evaluation.

Currently building a distributed crypto analytics platform using Node.js, TypeScript, NATS/JetStream, Redis, ClickHouse, and PostgreSQL, from data ingestion to real-time analytics to ML-powered predictions.
