About

Profile

I like building tech that creates real positive impact on society.

I have created tools that are used by thousands of students and frontliners, including an IGCSE exam paper generator with 1,500+ users and YearnOut, a firefighter alert app.

Currently, I'm deeply interested in agentic AI and multi-agent systems, and I have built several AI tools for real-world use.

My Work

Featured — 2026

YearnOut

Turnout alerts that cannot be missed.

A dispatch-alert system for firefighters. When the station turns out, every crew member's phone rings like an incoming call — full-screen, over silent mode — instead of a mutable notification. In use by 150+ firefighters across two fire stations, and cleared a security review by HTX (Home Team Science & Technology Agency) ahead of wider deployment.

On the App Store ↗ How it's built ↗

3D Incident-Scene Reconstruction

Walk through a building with an iPhone and, minutes later, orbit a photorealistic 3D Gaussian-splat model of it on the city map — built for an SCDF hackathon.

SwiftARKitnerfstudiothree.jsRunPod

Source & pipeline ↗

The capture app writes ARKit poses and LiDAR depth straight into nerfstudio's format — the whole COLMAP step is skipped
dn-splatter training with LiDAR depth and normal supervision on a cloud RTX 5090; a live trainer updates the splat while you're still walking
The three.js viewer overlays the splat on Google Photorealistic 3D Tiles, aligned in real-world metres, so commanders can brief from the actual scene
Motion-blur rejection and a coverage overlay show the operator which parts of the room still need scanning

RMSProp convergence charts from the extended essay

LSTM Optimisation Research

IB Extended Essay (Grade A) on how SGD, Adam and RMSProp affect a bidirectional LSTM trained on 1.6M+ tweets.

PythonTensorFlowColab A100

GitHub ↗

Six models varying only the optimiser and learning rate, on a binary and a three-class tweet dataset
RMSProp at lr 0.01 won both datasets — 0.988 weighted F1, converging in 18 epochs to SGD's 43
At lr 0.1 the adaptive optimisers never converged; the full essay is in the repo

IGCSE Exam Paper Generator

Assembles real Cambridge past-paper questions into custom IGCSE Maths papers — 1,500+ students, 14,000+ papers generated.

PythonAWS LambdaJavaScript

papergeneratorapp.com ↗ GitHub ↗

Pick topics and an exact mark total; a two-phase subset-sum dynamic programme picks real questions that sum to it — a different paper every time
Thousands of past-paper questions in SQLite, composed onto A4 pages with source stamps
Serverless: Lambda, S3 and DynamoDB behind API Gateway — usage tripling year on year

AI Friends Simulator

LoRA fine-tuning of BlenderBot-1B on my Instagram message history so it replies in a specific friend's voice.

PyTorchPEFT / LoRATransformers

GitHub ↗ Read the article ↗

Conversations segmented by embedding-similarity drops between neighbouring messages, not timestamps
Speaker-prefixed turns are the persona conditioning — the model learns how each person writes
Rank-8 adapters on the attention projections train under 1% of the parameters, fitting a free Colab GPU — one adapter per friend
Write-up published by AI Mind on Medium

Firefighter Leave Planner

A Telegram LLM agent that plans leave for a fire-station rota — 41 firefighters, 400+ requests, zero double-bookings.

n8nOpenAIGoogle SheetsVBA

GitHub ↗

The agent proposes structured changes; deterministic code validates and writes — the model never touches the sheet directly
Imports the official WhatsApp calendar, resolves nicknames against the personnel sheet, and diffs before writing
Evening alerts flag who will struggle to clear leave before their service ends
Rebuilt a second time as a pure spreadsheet engine in VBA and Apps Script, for stations that just want a file

Receipt Claim Generator

Photograph receipts, get back a completed Word claim form — saving ~6 hrs/wk per officer.

AWS TextractBedrockOpenAINode.js

GitHub ↗

Textract reads each receipt with per-field confidence; the model is never the source of truth for numbers — low-confidence fields stay blank for the officer to fill
Claude on Bedrock breaks ties between candidate totals; OpenAI writes readable item names and purposes
docxtemplater fills the organisation's own claim template — merged cells, tick boxes and signature included, plus a ready-to-send email

CookMate

An iPhone app that keeps you honest while you cook, and tells you exactly what to do when something catches fire — Swift Student Challenge 2026.

Swift 6SwiftUICore MotionCore Haptics

Walk-away detection with the pedometer — no location permission needed
A risk value climbs while you're away from the pan; haptics, then audio, escalate with it

Other Interests

Guitar

Been playing for 13 years, both acoustic and electric, and I post occasional covers on YouTube. My favourites are John Mayer, Kenny Rogers, and Arijit Singh.

Watch on YouTube ↗

Bansuri

The Indian bamboo flute — I taught myself four years ago, and I like playing Sufi songs on it.

Football

I play at Singapore Football Club, competing against professional men's and youth teams across Singapore. I captained my school team to our first championship title in five years.

Hiking

I've summited Mount Agung at sunrise and trekked to Tiger's Nest on its Bhutanese cliffside. I like the quiet up there — a few hours on a trail resets me better than anything else.

Coin Collecting

I collect coins that tell stories — 19th-century British silver my granduncle found in our village in Maharashtra, Mughal copper, North Korean won, Tibetan exile currency.

Firefighting

I spent two years as a firefighter with the SCDF, responding to fire, rescue, and medical calls across Singapore. Easily some of the most meaningful work I've done.
