Experience

Robotics Software Intern — KABAM Robotics | ROS 2, MQTT, Docker, Jetson Orin AGX, SAM3, Nav2, C++/Python May 2026 — Dec 2026

Matrix-4 autonomous delivery robot · Antler / Sequoia Surge backed

Building the Matrix-4 three-host stack across mission control, Nav2 navigation, Jetson vision, MQTT / ROS 2 coordination, and CAN bus chassis control.
Integrating SAM3 open-vocabulary detections into asynchronous re-planning; containerising services for Jenkins / Spinnaker / AWS Kubernetes and Kriya WebRTC remote intervention.

Teaching Assistant, CS2113 (Software Engineering & OOP) — NUS | Java, GitHub, CI/CD Jan 2026 — Present

Mentoring undergraduates on OOP design, JUnit, Agile GitHub workflows, and code review.

Aiko — Personal OS Agent (Solo R&D) | TypeScript, Node.js, SQLite, React Native, Tailscale, Ollama / OpenRouter / Kimi Apr 2026 — Present

Persistent agent across Linux daemon · phone · Telegram · VRM desktop stage

Built one persistent identity across four bodies with a 5-tier memory model, 6-dimension limbic state, structured event delivery, and encrypted Tailscale phone control.
Expanded to 88 manifest-backed skills and hot-swappable local Ollama, OpenRouter / MiniMax, Moonshot / Kimi, and CLI-agent providers.

PLAN.AI — Deep-Research Architect Co-Pilot | React, Vite, TypeScript, OpenAI / OpenRouter, Vercel Edge, Mermaid C4 Apr 2026

AI-Engineer Hackathon — citation-grounded technical blueprints

Built a STORM-lite co-pilot that researches 9 sources and produces inline-cited 22-section technical blueprints with Mermaid C4 diagrams, streamed through Vercel and compiled into implementation tasks.

Mera — Digital Health Companion (Team Lead) | Python, Next.js, FastAPI, SEA-LION, MERaLiON, MediaPipe WASM, Docker Feb 2026 — Mar 2026

Synapxe × IMDA AI Innovation Challenge — repo

Architected an agentic Telegram health companion orchestrating a fully Dockerised "Open Claw" stack (SEA-LION v3.5-8B-R + MERaLiON ASR/SER v1) for local inference without external cloud calls.
Engineered 3 WASM clinical mini-apps (Smile Checker, Mobility FSM, rPPG Heart Rate) running entirely on-device — 100% Smile precision, 92–98% Mobility FSM accuracy, 3.70 MAE rPPG vs clinical oximeter.
Implemented a trend-aware SQLite analytics pipeline injecting rolling N=20 baselines (mean/median/σ) into SEA-LION prompts so the LLM distinguishes temporary fatigue from progressive decline.

Shoppo — TinyFish Telegram Shopping Agent | Python, FastAPI, SQLite, Telegram Bot API, SSE, TinyFish Mar 2026

TinyFish-SG-Hackathon 2026 — repo

Built a Telegram-native shopping agent that converts vague text, photos, and budget constraints into structured sourcing briefs before dispatching grounded marketplace searches through TinyFish.
Implemented a FastAPI + SQLite run coordinator and SSE live-report flow preserving per-marketplace status, search URLs, screenshot paths, and streaming telemetry; ranks shortlists across Carousell, Lazada, Amazon SG, and Alibaba.

Wingman — Local AI Desktop Assistant | React, Electron, SQLite, Python, Ollama May 2025 — Present

NUS Orbital Apollo — repo

Engineered a fully offline desktop productivity app orchestrating IPC between a React frontend and a Python FastAPI backend; offline-first SQLite persistence keeps user data local.
Integrated local LLMs via Ollama with asynchronous background streaming natively in the user's host environment.
