What I'm looking for

I seek senior engineering roles building secure, high-availability fintech or e-commerce systems, leading cross-functional teams, mentoring engineers, and delivering cloud-native, AI-enabled solutions with strong operational and compliance focus.

I am a Staff Software Engineer with over 10 years architecting and delivering large-scale, mission-critical systems for fintech, e-commerce, and SaaS. I have led end-to-end product development that optimized complex workflows and delivered measurable gains in system performance, scalability, and operational efficiency.

I design cloud-native, event-driven architectures using Python, Go, Apache Kafka, React/Next.js, Kubernetes, and AWS, and I’ve integrated LLMs (LangChain, SageMaker) to automate triage and improve accuracy. I mentor engineers, drove cross-functional initiatives that cut resolution times by 30% and infrastructure costs by 15%, and prioritize security and compliance (SOC 2, GDPR, PCI DSS).
