Final-year CS at NUS specialising in Software Engineering. I build backend systems and care about where work belongs in a system.
Looking for a 6-month SWE internship starting early 2027.

• Teaching CS3219 Software Engineering Principles and Patterns at NUS as an academic tutor, August to December 2026. One of my favourite modules taken in NUS, and the one that opened my eyes to how broad software engineering gets once distributed systems are involved. It is microservices based, so teams spend the semester making real decisions: where a service boundary goes, which database suits the access pattern, how everything gets deployed and stays up. My job is to help them think those through before they commit
• Building DeepCS, a CS fundamentals question bank where two people solve the same question together in real time. Six independently deployable services on Cloud Run behind a gateway I'm writing rather than buying, a Yjs CRDT holding the shared document across instances, and an append-only event log a scheduled job drains into stats, which is where at-least-once delivery forces idempotency
• Building Recall after that, a search engine in Go, to understand indexing and retrieval by implementing them rather than reading about them

• 1st place, Daytona HackSprint by AI Builders at NUS (July 2026), for Airlock (below)
• Certificate of Distinction, Software Engineering focus area, NUS School of Computing
• Merged open source PRs in Automattic/mongoose and redis/node-redis, gaps I found by reading the source rather than working off issue labels

1st place at the Daytona HackSprint. A safety gate that sits between an AI coding agent and every package it tries to install.

• Each install is detonated in an isolated sandbox before it touches the system, then read statically, matched against known malware, and reputation scored, with an LLM issuing the final verdict
• Enforced as a hook rather than a wrapper, so the agent cannot route around it
• Weekend team build; a teammate and I shaped the concept and system design

Own venture. Sole engineer for a fragrance brand launching Dec 2026: storefront, backend and infrastructure.

• Backend on Supabase (PostgreSQL) and Vercel Functions: authentication, relational schema design, and caching
• React and TypeScript storefront with a Shopify hosted checkout, keeping payments and PCI scope off my stack
• CI/CD through Vercel, Cloudflare DNS and GitHub automation, with analytics supporting early testing across 100+ visitors

Built with:  TypeScript React PostgreSQL Supabase Vercel Cloudflare Shopify

Question Service owned end to end within a distributed 6-service architecture.

• 15 RESTful endpoints with input validation and standardized error handling (400/404/409/500)
• Moved randomized question selection into MongoDB aggregation pipelines ($match, $sample) instead of the application layer
• 35 unit and integration tests with Jest and Supertest covering CRUD workflows and the pipelines

Built with:  Node.js Express TypeScript MongoDB Mongoose Jest Supertest

NUS Orbital, Apollo 11 Advanced. Full-stack MERN app for creating and discovering study groups, matched on live NUSMods course data.

• REST APIs with session-based auth (express-session, bcrypt) and MVC structure, with MongoDB schemas for users, groups and memberships
• Parsed nested timetable data (20 to 50+ entries per module) into structured formats with multi-criteria sorting and search

Built with:  MongoDB Express React Node.js
