Hello, I am Duy

Duy

Software Engineer

Backend · Full-stack · Aspiring System Design & DevOps Engineer

I am a backend-focused software engineer with experience across the full stack — from designing REST APIs and async processing pipelines to building frontend UIs and browser SDKs.

Over the past 4+ years at Adstart Media, I have worked across multiple services in a polyglot environment — Java, Scala, PHP, TypeScript — integrating payment gateways, designing billing systems, and maintaining high-throughput data pipelines in the telecom and mobile VAS domain.

I care about clean, maintainable code: applying OOP principles, design patterns, and consistent refactoring to keep systems understandable as they grow.

My next goal is to move deeper into system design and DevOps — understanding how services scale, how infrastructure is provisioned and automated, and how to build systems that are reliable not just in code but in deployment.
