SHEET 02 · SIGNATURE WORK
Enterprise GenAI, in production.
What it looks like to run enterprise GenAI as a program, not a project.
GenAI Service Layer
When every team needs LLMs, you need infrastructure that turns chaos into reliability. Multi-cloud, multi-vendor, model-agnostic, with built-in routing, caching, observability, cost governance, and policy enforcement across 100+ production use cases.
Agent Service Layer
Agents aren't a feature you ship once. They're a class of system that has to be built, evaluated, validated, and operated. The framework standardises every step. Cuts the full pipeline (development, evals, human validation, load testing, deployment) from 16 weeks to 2 weeks or less.
Multi-agent customer chatbot
Customer-facing production AI handling 85K+ queries per week. CSAT lifted from ~50% to 80%+. A flagship example of what the Agent Service Layer can produce.
- Multi-agent orchestration with specialised sub-agents
- Parallel tool use and agentic delegation
- Human-in-the-loop escalation for high-stakes flows
- Persistent interaction + knowledge memory across turns
- Multi-step transactional workflows
Industry partnerships
Active engagement with industry-leading AI organizations: co-shaping enterprise GenAI roadmaps, evaluating frontier capabilities pre-release, and translating research into production.
Internal engagements
Building enterprise-wide AI fluency through training, upskilling, coaching, and mentoring across peers, engineering teams, business users, and senior leadership including C-suite stakeholders.
AI-powered travel-planning experience
Travel planning combines GenAI search with smart flight recommendations, built on the GenAI Service Layer. The experience connects shared AI infrastructure to measurable improvements in customer satisfaction and engagement.
- AI search: GenAI-powered search doubled customer satisfaction on the search experience.
- Flight recommendations: the recommendation surface averages 2,000 queries a day, with click-through rising from 23.8% to 34.4% in three months.
- Design recognition: the experience received Gold at the Asian Design Awards 2024.
SHEET 03 · WRITING
Latest essays.
MCP 2.0? What Changed, What Remained, and How it Impacts Practitioners
Working notes on the 2026-07-28 revision of the Model Context Protocol, from someone responsible for running it in a large, regulated enterprise. Written for peers carrying the same responsibility.
Your Agent Has Too Many Tools, and No Way to Take Any Back
Claude Opus 5 shipped with two beta features listed at the bottom of the announcement. One of them changes where an agent’s authority is allowed to live.
Open Weights Are Good Enough. The Hard Part Is Everything After.
They now match commercial models on most enterprise work at a fraction of the cost. The differentiating skill is no longer picking a model. It is drawing the open-versus-commercial line well, and running the open side with discipline.
SHEET 04 · HOW I THINK
How I think
Run GenAI as a program, not a project.
A one-off prompt is a feature.
Agents aren't a feature you ship once.
They're a class of system.
Prompts are technical debt.
Every prompt you write is a contract with a model version.
SHEET 05 · NOW
Currently working on.
The initiatives shaping the next chapter of enterprise GenAI at scale.
Agentic systems at scale
Pushing the Agent Service Layer into more departments. New eval harness, new tool primitives, faster idea-to-prod cycles.
Voice AI for internal ops
Native end-to-end streaming voice replacing legacy STT-text-TTS for internal staff workflows. Real-time, low-latency, prosody-aware.
Frontier model partnerships
Pre-release evaluations and roadmap co-shaping with OpenAI, Anthropic, Google, and AWS.
DocIQ + Tacit
DocIQ: hosted app deployed. Page-grounded document Q&A: lexical search, agent-directed exploration and visual inspection in a reusable retrieval engine. Tacit: local application. Scattered source material becomes useful organizational knowledge when people can trace, review and maintain it.
SHEET 06 · INPUTS
Reading & thinking.
A short list of what's shaping how I think this season.
Co-Intelligence
Ethan Mollick on living and working with AI. The clearest framing of human + agent collaboration I've read.
Anthropic's “Building Effective Agents”
The architecture patterns that hold up in production. Routine reading for anyone shipping agents.
Claude Code & Codex
The current state of AI coding agents. Reshaping how software gets written, not just how it's typed.
