The Point

Since ChatGPT went public, I have been working at least 12 hours a day — not because I have to, but because I finally have tools that match the speed of my own thinking. The bottleneck is no longer typing. It is deciding what to build next.

I can sit at a desk for a whole week without leaving. Not out of discipline. Because building is the most interesting thing in my life.

I am always obsessed with how the brain works, and what life is for. Everything I build feeds back into that question.


What I've Built

Cereblab

Built my own AI-assisted development harness from scratch. Not a wrapper — a full system with memory, RAG search, browser bridge, computer use, and blue/green deployment. The tool that runs this workspace.

Used it to discover and document the Grok Build CLI privacy vulnerability: it uploaded entire private repositories — full git history and secrets — to the cloud regardless of opt-out settings. Proven via wire-level mitmproxy analysis and a public reproduction harness. Covered by Inc., The Register, The Hacker News, Cybernews, TechTimes and 20+ outlets. Prompted a public response from Elon Musk.

QuizStop

Founded and built QuizStop, an AI-driven education platform for web, iOS and Android. Sole developer implementing speech-to-text, text-to-speech (50+ languages), answer evaluation, multilingual translation, and real-time interaction via WebSockets. 90% of the codebase produced through AI-assisted development; 10% through system design, debugging, and infrastructure.

Designed and operated the full architecture: Cloudflare Worker API, Azure deployments, database, storage, SES mail service, and CI/CD pipelines. Delivered an interactive learning platform for children and automated assessment tools for teachers.

JomeInvoice

Technical lead for JomeInvoice.my, an e-invoicing platform for Malaysia's MyInvois / LHDN compliance. Heavy applied AI across managing infrastructure, development work, testing, and verification. Leading V1 and V2 stack — integrations, AWS infrastructure, and LHDN validation.

Platform One

Led backend and frontend development of the Insight platform used by Toyota, Hyundai, Genesis and major Australian automotive clients. Built and maintained large-scale systems using Laravel, Angular, PHP, TypeScript, and Elasticsearch. Designed and operated AWS infrastructure (EC2, RDS, SES, Route 53, ECR, CloudFormation, IAM, Auto Scaling). Mentored developers and acted as the technical safeguard during outages.


The Edge

People with the same access to the same resources as me — I am always number 1 in the room. Not because of IQ. Because of speed of learning, depth of focus, and willingness to sit with a problem until it breaks.

I love science and technology. I read papers, build harnesses, and verify things at the wire level. I do not trust claims — I trust traces.
