Work

Products, systems and the decisions behind them.

Open a project to see what broke and what I changed.

AI study infrastructure

LearnLoop

An AI study layer inside SUTD's learning platform. It answers from approved course material and keeps the exact source slide beside every response.

  • S$2,000university build funding
  • S$7K test waivedafter redesigning the trust boundary

Passed SUTD EduTech's first cybersecurity review by moving students behind LTI 1.3 and EASE SSO, removing public signup and reducing Blackboard access to least privilege.

SEO research system

Rankr

An AI SEO agent for Singapore SMEs that finds demand and competitor gaps, drafts from real audience questions and helps businesses show up on Google.

  • US$10,000OpenAI credits awarded at UCWS

Our checker gave Lullaflex scores between 93 and 100. Google still ignored it. That failure changed what Rankr measures.

Launch video pipeline

Proof

Proof reads a GitHub repo, finds a story worth telling and turns it into a script you can record from a teleprompter. It then cuts the take, adds captions and motion graphics, and exports a vertical video.

  • Invite-only betarunning at tryproof.org
  • 20% faster rendersafter load-testing the safe concurrency limit

Proof checks three frames from every generated scene. If text clips, copy breaks or a graphic covers the speaker, it patches that scene and renders it again.

A local-first Chrome extension that pulls SUTD deadlines into one sortable list and exports them to a calendar.

50+ studentsweekly users
