Side projects
Built on weekends, on my own hardware, where breaking things costs nobody anything.
AI & automation
Automated trading bot
A rule-based signal engine places risk-sized orders with stops attached. An AI review layer reads the bot's own track record and proposes tuning, and anything that would raise risk waits for my approval.
Control room for AI coding agents
A self-hosted dashboard that watches AI coding agents across all my projects, with a ticket board, in-browser approvals for their actions, and a chat assistant I can reach from my phone.
AI coding-agent workflows
Custom skills, hooks, sub-agents and tool integrations that automate the parts of the development loop that repeat.
Multi-account cloud AI assistant
An MVP with one orchestrator dispatching to workers, each scoped to its own cloud account, so several accounts can be reasoned about without cross-contamination.
Conversational search assistant
A hackathon build that remembers preferences across turns, runs semantic search over Singapore's open government datasets, and surfaces shopping and travel links on request.
Subtitle reading and translation pipeline
Reads subtitles burned into video frames with GPU text recognition, then translates them with an AI model into a clean subtitle file.
Infrastructure
Self-hosted zero-trust homelab
Docker, tunnelled zero-trust ingress, a mesh VPN and WireGuard for remote access.
Games
Browser multiplayer RPG
A shared town and instanced zones in real 3D. The game server owns every value and a Postgres backend keeps the world, so a client can never cheat its way to loot.
Tower-defence game on Roblox
Server-authoritative and data-driven: towers, enemies and waves are config tables, and the maps are built procedurally at runtime.
Small builds
Fireworks line-of-sight checker
Enter a postal code and floor, and a real sightline calculation against the surrounding buildings says whether you can see the National Day fireworks from home.
AI to apparel, end to end
A print-on-demand experiment testing whether one operator can close the whole loop: image generation, mockup, storefront, organic discovery and direct fulfilment.
Website for a home café
A hand-written, no-build site for a neighbourhood home café: the menu, pickup details and one-tap ordering over chat.
