Tools built around real questions.


Forge commercial intelligence dashboard

Forge

I wanted to understand what it takes to turn frontier research into commercial traction — so I built the operating system for it. Forge sits on a research knowledge graph of real capabilities, benchmarks, and partner results, and turns them into prospect scoring, deal architecture, prediction tracking, and a weekly brief that can be read in 60 seconds. Nine interfaces, ~80 components, every number traced back to a published paper.

Pulse dashboard

Pulse

Generic news tools weren't built for the people who need to know the moment a specific narrative starts moving — the comms lead tracking how their company gets talked about, the DevRel trying to stay ahead of every mention of their product, the PMM watching a competitor launch unfold in real time. When I was a DevRel, I spent hours every morning manually piecing this together across Discord, Twitter, and a dozen newsletters. Pulse is the tool I wished existed: tell it what you care about, and it monitors sentiment, tracks narrative drift, generates tailored briefs, and fires Slack alerts when something breaks. The demo is configured for Anthropic's communications team, but the engine works for any company or topic.

RosterAI smart shift allocation dashboard

RosterAI

When I went back to Singapore, my friends who had become doctors kept bringing up the same problem. Every month, one of them loses an evening to creating the on-call roster. A shared spreadsheet, dozens of names, leave requests, swaps, call preferences, variations of minimum staffing per team on every shift. It takes hours, on top of a day of work in the hospital.

I asked four of them to sit down and walk me through it properly. I built RosterAI over 3 weekends. Doctors enter their preferences, a roster comes back in seconds, and anyone can check who's on call from their phone.

Buddy app

Buddy

A place-saving and guide-sharing app I built solo from zero. AI-generated city guides, semantic search, a taste graph that learns what you love, and trip journaling with time-travel. The kind of app I wanted to exist, so I made it. 27 days from first commit to full product.

Beacon campus intelligence dashboard

Beacon

Beacon is a campus intelligence operating system. It runs the ambassador pipeline, faculty outreach, and student discount program from one dashboard. Three layers: Strategic Intelligence (professor enrichment from arXiv, faculty outreach with Claude-drafted emails grounded in real papers, Monday workqueue), Ambassador Ops (four-dimension scoring, health tracking, enablement resources), and Community Ops (SheerID verification queue catching silent failures, event tracking with attribution codes). Every number traces to a source. Every decision logs an observation.

EchoAid NFC accessibility app

EchoAid

Two medication bottles that look identical except for their labels. One wrong choice could be dangerous. At Black Wings Hackathon 2024, we built EchoAid — an NFC app that lets visually impaired users attach voice-tagged stickers to everyday objects and identify them with a tap. We didn't start with the technology. We started with user stories. Winner, Most Innovative Hack — 1 of 78 teams.

Mental Health Collective featured in The Straits Times

Mental Health Collective

At 18, I co-founded Singapore's first nationwide youth mental health initiative. No template, no institutional backing. We built government partnerships from cold outreach, designed a conference system that scaled to 3,000+ attendees, and created infrastructure that outlasted us. This is the project that taught me what building for people actually means.
