I build high-throughput microservices and web applications that improve API performance and customer experiences.

I've built critical API modules for Yettel serving 200k+ daily requests, including a NestJS caching layer that cut response times by 50% across key microservice endpoints.

I develop full-stack products across PHP, React, Vue.js, and Laravel—from CRM components and employee admin panels to self-service portals and progressive web apps. I also led and mentored a team of three engineers, driving Agile sprint delivery with stakeholders.

At Flyeralarm, I reduced event-store payload size by 50% and increased I/O throughput 3x with Apache Avro, while Golang APIs accelerated data processing 5x. Earlier, I delivered Laravel, Vue.js, Stripe, WordPress, and database optimization work as a software engineer and freelancer.
