What I'm looking for

I seek senior engineering roles at data-driven companies to design scalable, secure cloud-native systems, mentor engineers, and deliver measurable product and cost improvements in fintech, healthcare, or e-commerce.

I am a senior software engineer with over 10 years of full-stack experience building scalable fintech, healthcare, and e-commerce systems. I specialize in architecting high-performance services and real-time analytics that support large transaction volumes and critical user workflows.

I designed fault-tolerant, event-driven payment reconciliation systems handling $2B+ annual transactions and built financial analytics dashboards that process 100M+ monthly transactions with sub‑200ms response times. I've implemented ML-powered engines that cut manual processing by 50% and improved accuracy to 99%, while maintaining strong test coverage and performance optimization practices.

I enjoy mentoring engineers, establishing code review standards, and delivering secure, compliant applications (HIPAA). I'm seeking roles where I can lead technical design, improve system reliability, and drive measurable business impact.
