I am Arthur Teng, a Computer Science undergraduate at the National University of Singapore. I build end-to-end applications that combine clean frontend experiences, reliable backend systems, and practical security thinking.
Hi, I'm Arthur — a Computer Science undergraduate at NUS (GPA 4.15/5.0) with hands-on experience shipping full-stack products across the whole development lifecycle. I've built and deployed applications using React, Vue 3, TypeScript, Node.js, Go, and Java, integrating cloud services like AWS S3 and DynamoDB, and I care about writing code that is secure, maintainable, and purposefully structured.
I completed a Software Engineering internship at PatSnap, where I built AI-driven web interfaces with Vue.js and TypeScript against production REST APIs. Outside of coursework and internships, I independently design and ship my own projects — from an equity research platform with cloud-backed authentication, to a full-stack discussion forum with RBAC and security-hardened endpoints. I'm drawn to backend systems and security, and I actively sharpen those skills through self-study in PostgreSQL, and hands-on testing with tools like Burp Suite and Caido.
Comfortable taking a feature from schema design and API layer through to a polished frontend and deployment.
I think about RBAC, least-privilege, and input validation from the start, not as an afterthought.
Built and deployed multiple full-stack applications independently, including cloud-integrated systems with real auth flows.
Developed through RSAF pilot training — I debrief methodically, iterate quickly, and don't cut corners under stress.
Current GPA: 4.15 / 5.0. Coursework spans software engineering, data structures, algorithms, and systems programming.
Built AI-driven web interfaces in Vue.js and TypeScript, consuming production REST APIs for interactive data and agent-based systems.
Developed sharp situational awareness and a structured debrief culture — habits that carry directly into how I approach engineering problems.
Led a fundraising initiative and launched a YouTube channel to raise awareness for wildlife habitat conservation.

A full-stack equity research platform using React/Vite and Node.js/Express with dynamic JSON-based report loading, schema validation, audit tooling, and a modular frontend for rendering structured stock research reports. Integrated AWS S3 for scalable report storage and DynamoDB-backed API key authentication to secure all research endpoints.
A Java desktop application using MVC architecture to manage students, assignments, and milestone tracking via a command-line interface. Implemented core backend logic including command parsing, data modelling, and filtering with a focus on clean, maintainable code.
A full-stack discussion platform built with Vue 3, TypeScript, Go, and SQLite, designed for company-centric structured insights alongside equity research. Applied security-focused development practices including RBAC, least-privilege principles, and testing with Burp Suite and Caido.
