Message

I am a Full-Stack & DevOps Engineer specializing in TypeScript, Next.js, Node.js, and PostgreSQL, backed by Docker containerization and Linux VPS orchestration. I focus on building reliable, high-concurrency web systems that stay resilient under live production traffic.

Most recently, as Lead Full-Stack Engineer for our university’s engineering platforms, I architected real-time competition infrastructure (NPLC & C-Think) serving 33 high schools and 128 contestants. I engineered type-safe Next.js and PostgreSQL architectures, WebSocket event pipelines, and sandboxed Judge0 compilation runners that processed 1,635+ round submissions and 833 live code evaluations with zero downtime.

Alongside web platforms, I am an intern at the Apple Developer Academy @ UC (Cohort 2026), where I’ve shipped 4 native releases to TestFlight using Swift, SwiftUI, and SwiftData, emphasizing dependable client-side state management and Apple’s Human Interface Guidelines (HIG).

I have also served 6 times as a Computer Science Teaching Assistant at Ciputra University, mentoring 200+ undergraduate students in relational database schema design (3NF), SQL query plan optimization, and software architecture.

What I work with:

Languages: TypeScript, JavaScript, Swift, PHP, Java, SQL, Python
Web & Backend: Next.js, React, Node.js, Express, Laravel, Tailwind CSS, Prisma, WebSockets
Databases & DevOps: PostgreSQL, MySQL, Redis, Docker, Linux (Ubuntu VPS), Nginx, GitHub Actions (CI/CD), Git
