What I'm looking for

I’m looking for a backend role where I can build secure microservices and payment systems, optimize performance with clean architecture, and ship reliably using CI/CD, Docker/Kubernetes, and strong collaboration with product and frontend teams.

I’m a Backend Engineer with 6+ years of experience designing, developing, and deploying large-scale, secure, and scalable systems. I specialize in simplifying complex backend challenges into reliable solutions—especially in corporate and high-volume payment domains.

At Bykea, I designed and maintained scalable microservices on AWS EC2, improved uptime, and reduced deployment risks using automated GitLab CI/CD. I optimized API response times by reducing redundant database calls and caching queries, and I built and integrated payment gateway services handling authentication-to-payment workflows for millions of transactions.
