What I'm looking for

I’m looking to build backend systems at scale and ship AI/RAG features in production—where reliability, observability, and fast iteration matter.

At Securonix, I scaled a high-throughput SIEM platform from 1M to 2M+ TPS and re-architected the User Import workflow to cut processing from 6–8 hours to minutes. I also designed AI-powered production support agents to automate log analysis, code inspection, and root-cause identification.

At Mastercard, I shipped multi-region resiliency for a high-availability payments clearing platform and built an end-to-end contactless payment solution for Africa expansion. I improved backend processing throughput by 30% with a reusable event-driven authentication library and reduced test instability by 30% using JUnit-based integration tests.

Before that, I joined TartanHq as a founding software engineer and built the Perks benefits platform from scratch, onboarding paying customers within 3 months. I led a team of 8 engineers, mentored across Agile sprints, and helped cut AWS infrastructure costs by 30% through refactoring and Redis caching.
