What I'm looking for

I seek senior/staff engineering roles where I can shape technical strategy, architect scalable platforms, lead cross-functional teams, and drive ML/real-time system reliability.

I am a Staff Software Engineer with 13+ years building scalable, high-performance web and mobile platforms, marketplace systems, real-time communications, and AI/ML pipelines. I have led complex projects end-to-end, optimized high-traffic GraphQL and microservice architectures, and stabilized ML pipelines under production data drift.

My work has spanned architecting multi-merchant checkout and real-time inventory sync with Kafka/Flink, building PCI-compliant payment systems on Kubernetes, and prototyping GenAI services with vector embeddings and LLM orchestration. I focus on technical strategy, secure data flows, operational observability, and delivering measurable performance and compliance improvements.
