What I'm looking for

I'm looking to build production-grade, high-concurrency platforms where I can own architecture through deployment, work with microservices and event-driven systems, and contribute to strong engineering standards.

I've built high-concurrency platforms at Ajke Technology and Gaze, spanning quick-commerce, fleet management, fintech, and edtech.

At Ajke, I engineer distributed NestJS and Go backends that process thousands of daily transactional events through PostgreSQL, Redis, and BullMQ. I also designed dynamic pricing and automated dispatch systems that improved logistics efficiency by 20%.

I've scaled Deliveryhobe across 200+ stores, accelerating fulfillment by 30% through real-time inventory synchronization and optimized routing. I also launched GazePay, a face-authentication e-wallet validated by 1,000+ active users.

I enjoy owning architecture through deployment, building event-driven microservices, and helping teams adopt TypeScript-first engineering standards.
