I’m a lead software developer with 12+ years of experience, including 10 years at Amazon, building high-scale distributed systems across identity, KYC, payments, compliance, and retail catalog platforms. I specialize in designing secure, multi-tenant, high-TPS systems with strict latency and availability requirements. My work has involved architecting foundational platforms serving tens of millions of users, scaling ingestion systems 25× under cloud constraints, leading zero-downtime migrations, and driving long-term operational excellence. I have deep hands-on experience with AWS-native architectures, event-driven systems, data pipelines, and ML-enabled catalog enrichment, including RAG-based systems in retail contexts. I operate with strong ownership — from system design through production reliability — and enjoy solving complex problems at the intersection of scale, security, and product impact.…I’m a lead software developer with 12+ years of experience, including 10 years at Amazon, building high-scale distributed systems across identity, KYC, payments, compliance, and retail catalog platforms.
