I'm Alvin Ben Abraham - a software engineer at TikTok working on Shop Homepage. I care about bettering user interfaces and building an internet that puts people first. Coding, cycling, and cinema-ing on the side.
Technical owner of Popup Infrastructure serving 2B+ MAU across SEA e-commerce surfaces. Architected a no-code Golang BFF engine that enables new popup releases without any FE code changes. Improved render latency and API prefetching by 30–50% on low-end devices.

Built a NodeJS/MongoDB REST API to group 200+ users by location for a live dynamic map. Drove mobile users from 20% to 74% by shipping full mobile responsiveness for the social networking app.
Telegram bot (@fridgetbot) that tracks fridge inventory and sends expiry reminders to cut food waste. Python-backed, SQL-persisted, Heroku-hosted. Built solo end-to-end in under 5 weeks.
Self-initiated, nationwide inter-university ideathon with 200+ participants, sponsored by James Dyson Foundation, Silicon Laboratories, and nSearch Global. Secured a $6,000 prize pool from scratch. Handled marketing, operations, and event execution.
Led the computer vision team: deployed YOLOv5 on PyTorch and YOLOv4 on TensorRT with ROS 2 for real-time target detection at <20ms latency. Integrated CSI camera on a Jetson Xavier NX and resolved pre-existing robot hardware issues.
I'm passionate about bettering the quality of user interfaces - creating an internet that is user-first. If you want to engage your users and create more value for them, let's talk.
I'm a software engineer at TikTok, shipping features for the Shop Homepage that move GMV 5-10% per feature, and maintaining the BFF framework that the wider frontend org builds on.
Before TikTok full-time I interned at Unit21 in San Francisco on SOC2-compliant financial compliance tools, and earlier at TikTok in Singapore where I helped ship e-commerce features across 5+ countries. Before that I was sole frontend at Interseed Co., a TA at NUS, and software VP at NUS RoboMasters working on computer vision for ROS 2.
Outside work: coding, cycling, cinema-ing.
