    01. About Me

    Profile picture

    I'm a senior backend engineer who doesn't just write code—I build products that ship fast and scale clean.

    With 7+ years of experience in Node.js, NestJS, PostgreSQL, MongoDB, and AWS, I specialize in turning backend chaos into simple, stable, and scalable systems. From building real-time POS platforms to secure transaction flows, I know how to move fast without breaking things.

    More than a developer, I think like a product person—focusing on user experience, reliability, and maintainability from day one. Whether it's designing APIs, setting up infrastructure, or debugging edge cases, I take ownership from idea to deployment.

    🔧 What I bring: Rapid backend development with clean architecture, AWS-powered scalability (Lambda, EventBridge, RDS, EC2), real-world problem solving from production fire-fights, and a mindset built for startups: lean, reliable, fast.

    📬 If you're building something meaningful and need a backend engineer who can own the tech while thinking like a founder—let's connect.

    02. Where I've Worked

    Lead Architecture @ Dirtube Interactive

    2023 - 2025

    Project: Specter

    • ▹Optimized MongoDB performance by reducing the return vs scanned document ratio from 1:1000 to 1:10, significantly improving query efficiency within an achievement system.
    • ▹Built a complex live-ops scheduling system using Redis queues to manage tasks, competitions, and other scheduled events.
    • ▹Developed and deployed APIs and CI/CD pipelines via AWS CodePipeline for automated, multi-environment deployment.
    • ▹Established company-wide technical standards and best practices for backend development, improving code quality and reducing onboarding time.
