# Sumana P > Software Engineer | Built & scaled fraud decision systems handling 5M+ daily transactions | Low-latency APIs, distributed systems | Java, Python, React, AWS | Location: United States, United States Profile: https://flows.cv/sumanap I’m a Software Engineer building and operating distributed systems in fintech and payments environments where reliability, performance optimization, and customer impact directly affect real-world decisions at scale. I work on high-performance backend services handling millions of daily transactions, improving application performance and scaling efficiency, including measurable latency reductions and stronger system stability under peak load. I own systems end-to-end, from system design and client-side architecture decisions to backend implementation, testing, deployment, monitoring, and iteration within full SDLC cycles. I focus on solving ambiguous problems, evaluating trade-offs, and delivering solutions that balance engineering rigor with business impact. Beyond core platform work, I’ve contributed to emerging AI-driven automation initiatives, assessing where LLM-enabled workflows can improve operational efficiency without compromising reliability or observability.
