Building software that thinks, scales and ships.

AI Systems · Product Engineering · Architecture · Infrastructure

Hello.

This is my professional GitHub profile — the place where I build, experiment and ship production software.

My work sits mostly at the intersection of:

Artificial Intelligence
Distributed systems
Product architecture
Backend engineering
Cloud infrastructure
Automation
Developer tooling

I care about turning complex systems into products that feel simple.

Currently building

◉ AI Agents

Conversational systems that actually interact with real business infrastructure.

◈ Platforms

Multi-tenant products, APIs and internal platforms designed to scale.

⬡ Infrastructure

Edge computing, queues, databases, workers and distributed workloads.

◇ Experiments

Rust, protocols, automation, AI tooling and ideas that probably started at 2 AM.

Engineering philosophy

01  Simple interfaces.
02  Strong boundaries.
03  Observable systems.
04  Automate boring things.
05  Measure before optimizing.
06  Architecture should serve the product.
07  AI is a component — not the architecture.

Architecture > hype

I like AI, but I'm even more interested in the systems around it.
