What I'm looking for

I seek backend roles focused on scalable API systems, performance optimization, clear CI/CD practices, collaborative agile teams, mentorship opportunities, and measurable impact on product reliability.

I am a backend developer with about 3 years of hands-on experience building scalable backend solutions using JavaScript and TypeScript. I design and implement robust RESTful APIs, integrate relational and NoSQL databases, and optimize system performance to support growing user demand.

At Konga I resolved critical inter-service communication issues, built an in-house AI-powered recommendation engine that improved accuracy by 35% and reduced costs, and developed core backend features for affiliate administration. Previously, I led a backend team at SeamFlex, engineering real-time ride-matching and dynamic booking/payment systems while maintaining high production uptime.

I prioritize best practices in architecture, automated testing, CI/CD, and observability, and I mentor junior engineers to improve code quality and team productivity. I am motivated to deliver reliable, efficient backend services that drive measurable operational improvements for employers.
