What I'm looking for

I'm looking to bring hands-on backend ownership, distributed-systems expertise, and team leadership to a global product company.

At RAKBank, I own solution architecture through production for customer-facing KYC outreach and onboarding services. I lead 4–7 developers while building Java and Spring Boot APIs, distributed pipelines, and operationally reliable backend systems.

I engineered a batch-processing pipeline for 100,000+ customer records that increased completion rates by 30% and reduced manual downstream work by 70%. I also resolved high-load memory bottlenecks for 300K+ records and designed Redis-based distributed locking to prevent concurrency race conditions.

Previously at Oracle, I delivered expense, approval, notification, search, and ERP capabilities used across production products. My work included migrating monolith functionality to microservices, reducing onboarding latency to 3 seconds, improving search performance by 30%, and cutting UI response time by 7–8 seconds through Redis caching and SQL optimization.

I've led teams of up to 25 engineers, mentored developers, and stayed hands-on from architecture and code through testing and production support. I'm looking to bring end-to-end backend ownership and engineering craft to a global product company.
