What I'm looking for

I seek senior engineering roles where I can design scalable cloud-native systems, mentor teams, work with ML/blockchain integrations, and deliver high-quality, testable production software.

I am a senior full-stack engineer with 12+ years in IT, experienced building scalable web applications using React, Node.js, Python (Django, FastAPI), Java, and modern cloud tooling such as AWS, Docker, Kubernetes and Terraform. I have led cross-functional teams, introduced microservices architectures, and integrated advanced capabilities including LLM-based assistants and blockchain features to drive measurable improvements in reliability and user experience.

My work spans backend and frontend development, DevOps, test automation, and embedded/C++ integrations for computer-vision systems; notable achievements include reducing cross-team dependencies by 60%, improving first-response accuracy by 35% through LLM integration, and achieving 95%+ automated test coverage across services. I prioritize clean, maintainable code, scalable architectures, and mentoring engineering teams to deliver high-quality production systems.
