I've built scalable web applications, microservices, and AI-powered products across EPAM, Vividly, and Belzabar Software Design. At EPAM, I architected Safeco's event-driven post-bind form-generation workflow using AWS Step Functions, Lambda, and SQS to support an estimated 200K+ annual transactions.

At Vividly, I designed Node.js services with Redis Pub/Sub and Socket.IO that improved responsiveness by 90%, built a Cloud Run invoice-scraping service that reduced manual retrieval time by 70%, and developed an OpenAI Threads chat application that cut user navigation time by 70%.

I've led full-stack interviews, conducted code reviews, mentored engineers, and managed a team of five. My work spans TypeScript, Node.js, Python, Django, React, AWS, Google Cloud, Docker, Kubernetes, Redis, Celery, and Elasticsearch.

I'm especially interested in practical AI systems: I built a call analysis platform processing 20K+ customer support calls daily and an AI learning assistant using LLaMA-2, OpenAI, RAG, vector embeddings, and semantic search.
