My expertise lies in crafting fault-tolerant services that are used by millions, optimizing infrastructure for performance and reliability, and bridging backend systems with AI-driven analytics and secure frontend interfaces.

Throughout my career, I have integrated financial APIs and smart contracts, mentored engineers, and tightened compliance workflows. I focus on practical, reliable code that holds up under pressure and scales with confidence. My work has led to significant improvements in operational efficiency, user engagement, and system reliability, making a tangible impact in the organizations I have been a part of.
