Focus

Cloud & Backend Development

With a strong interest in AI, building toward Solutions Architect

My Story

I came into Singapore Polytechnic expecting three years of CRUD apps. The internship had other plans.

At Reachfield, I shipped enterprise Java and React Native apps, plus a YOLO crowd-counting task that got me curious about AI. I also learned to think like a user: design test cases, classify severity, write bug reports that actually get fixed (30+ critical bugs caught along the way). It changed how I build.

"The world doesn't need more people who can call an API. It needs people who understand what the API is hiding, and what breaks when it doesn't."

Cloud is where I'm headed next, on my own terms. I'm currently preparing for the AWS Solutions Architect Associate certification, with AI as the thread running alongside it. I want a team building production-grade systems: cloud infrastructure, QA, or backend, where I can keep growing into both.

Experience

Where I've
built things.

Real production work, real users, real consequences when it breaks.

Junior AI Developer

Reachfield IT Solutions · Singapore

Worked across the full stack of SGEMS2 — an enterprise security and estate management platform deployed at facilities across Singapore. Migrated Hibernate 5→6, rewrote DAOs for Jakarta EE compliance, built two production React Native apps (Work Order + Form Management), integrated K10/F2 hardware devices, and developed a real-time computer vision pipeline for emotion detection and crowd density analysis. Both mobile apps shipped to Google Play and TestFlight.

AI / CLOUD ARCHITECTURE

Code-to-Cloud V1

Paste any code, get back the AWS architecture you should use. Recommends services, calculates monthly costs across three traffic tiers, and explains reasoning with Well-Architected Framework alignment. Built end-to-end on AWS: React frontend, API Gateway, Lambda, and Bedrock (Claude Haiku 4.5) doing the analysis. V1 takes 5 to 10 seconds per analysis while the AI reasons through your code.
