About
Engineer at heart. Not the kind of CTO who stops coding — the kind who opens Google Colab on weekends to experiment with MoE architectures, vibe-codes with DeepSeek, and builds multi-agent AI systems hands-on. 150+ technical articles. 9K StackOverflow reputation reaching 1.5M developers. 20+ years turning complex, regulated organisations into high-performing technology engines. Whether it's the 2nd employee of a startup building to multi-million dollar acquisition, or a CDTO leading an AI-first SDLC transformation — I build, ship, and scale. Fewer Developers, More Builders.

Builder DNA
Not a PowerPoint CTO — a builder who ships. Whether it's a startup from zero or a post-merger enterprise, I build with my hands and lead from the front.
Startup Builder
2nd employee of a tech startup — built APAC engineering from zero to acquisition (millions in revenue). Secured government R&D funding, built iBeacon SDK, designed rich media ad solutions across mobile and smart TV. Entrepreneurial DNA: when there's nothing, build it.
Enterprise Transformer
Consolidated 30+ legacy systems into 4 core platforms, migrated 90% to cloud, scaled to 100+ engineers across 4 countries. Led post-merger integration lifting delivery success from 20% to 100%, cut IT OPEX by 40%. Stabilise first, then scale.
Hands-on AI Builder
Codes on weekends in Google Colab. Built multi-agent career coaches with AutoGen (iterated for weeks), kid-safe AI agents with Singapore-specific PII detection, shipped with Google ADK days after release. Fine-tunes models in Node.js, vibe-codes with DeepSeek, automates UI testing with GPT-4+Playwright. 28+ technical articles — all built, not theorised.
AI-first Team Leader
Led the team's first AI-first projects — from Brown Bag sessions on GenAI to enterprise AI transformation across sales, finance, and SDLC. Built a culture where engineers experiment with LLMs, ship AI agents, and treat AI as a core engineering capability, not a buzzword.
Impact
Numbers that matter — results delivered across enterprise transformation, AI adoption, and engineering scale.
