Software Engineering Lead

About Me

I'm Shiva Kumar Pati, a Software Engineering lead with a strong background in designing and delivering secure, scalable solutions for large-scale distributed systems. My specialized expertise is in backend development, particularly within the cybersecurity and financial technology domains.

As a technical leader, I spearheaded the re-architecture of financial applications disbursing billions of dollars annually, guiding cross-functional engineering teams through full delivery. I led the automation of critical workflows across Payments, Treasury, and Accounting, and developed a platform capable of processing petabytes of financial data at scale. My work extended into securing payment applications and driving regulatory compliance across international payment frameworks. I designed and deployed a secure credential management platform for a mission-critical financial application, and most recently architected a new system that automates application security posture assessment — leveraging multiple data sources and LLM-based code analysis to deliver high-fidelity security insights at enterprise scale.

As a Senior Consultant, I leveraged my ERP expertise to guide companies in the finance sector. I was responsible for developing their enterprise software strategy.
