What I'm looking for

I seek senior engineering roles building scalable AI/ML and distributed systems with strong MLOps and cloud practices, emphasizing security, performance, and measurable impact.

I am a Senior Full-Stack Engineer and AI/ML architect with 8+ years building enterprise-scale distributed systems, GPU computing infrastructure, blockchain marketplaces, and geospatial/ML platforms. I design and implement production-grade microservices, MLOps pipelines, vector search/RAG systems, and secure decentralized architectures that support tens of thousands of concurrent users with high uptime.

My work spans end-to-end system architecture, from data ingestion and real-time streaming to model training, serving, and CI/CD automation using modern stacks like TypeScript, Python, Rust, Kubernetes, AWS, LangChain, and DeepSpeed. I deliver measurable outcomes—reducing site selection time by 70%, achieving 95%+ business categorization accuracy, and enabling 50K+ concurrent users with 99.9% SLA—while prioritizing security, scalability, and developer experience.
