I build AI platforms
from scratch.
I embed with teams to ship production AI systems — agents, pipelines, and the full-stack infrastructure behind them.

Client Work
AI Agents Built for Clients
Production agents deployed for real businesses — handling orders, locating showrooms, and automating workflows over WhatsApp.
Order Processing Agent
Reads parts lists from images, resolves stock conflicts, builds a cart, and generates a purchase order — end to end.
Showroom Locator Agent
Finds the nearest dealership from a shared location via WhatsApp and books a test drive in one conversation.
Internal Tools
AI Infrastructure Built for Companies
Production-grade internal platforms that let teams build, deploy, and maintain AI agents — without touching the underlying models.
Agent Builder
< 1 hrto deploy
A no-code wizard that lets any team build a fully configured production AI agent — from personality upload to live deployment.
Agent Debugger & Fixer
85%issues auto-resolved
Drop a failing trace into Slack. The system pulls logs, reads the agent's tools, diagnoses the root cause, and opens a fix PR — automatically.
About
From Dota to production AI
I got obsessed with AI in 2017 after watching OpenAI beat Dota 2 pros. Since then the path has run through a self-taught gap year, a Top 1% Kaggle finish in computer vision, 3x hackathon wins in Singapore, production work at Covena building sales AI agents, and now enterprise AI at EY. I also share parts of that journey by making AI reels on Instagram.
Now I'm a Senior AI Engineer at EY, building evaluations from scratch on EY's agent platform and AI solutions for enterprise customers across APAC. Before that, at Covena, a Silicon Valley VC-backed AI startup, I built the agents, tooling, and infrastructure that helped forward deployed engineers ship client AI agents faster. That work cut AI agent build time by 97%, resolved 85% of AI bugs autonomously, supported 5K+ daily AI conversations, reduced cloud costs by 90%, and made retrieval 10x faster.
Agents and orchestration
I build end-to-end agent systems, from prompt and tool design to internal platforms that help teams create, test, and improve them faster.
Self-improving systems
I ship an MVP fast, learn from real usage, and build the eval and feedback loops that make the AI better over time.
Full-stack delivery
I ship the surrounding product too: Next.js and Express apps, APIs, CRM features, dashboards, WhatsApp integrations, Docker-based deployment, and observability.

Contact
If you're building with AI, let's talk.
Whether you're looking for a technical engineer who can actually ship, or you just want a second opinion on AI agents, evals, or architecture, I'd be happy to chat.
Email is the easiest way to reach me. If you want to browse a bit first, the rest of my socials are here too, along with my resume.
If you already have a rough use case, I can usually tell pretty quickly whether you need an agent, better tooling, or a simpler automation path.
Get In Touch
Best for hiring conversations, collaborations, or AI agent questions. Email is still the fastest route.
