What I'm building

What I'm working on right now, and the decade of side quests that got me here. Every card links to the real thing.

My work

Where I spend my days

The company I lead engineering at, and the product I founded.

CTO2020 – now

Metafic

Hiring and managing an engineering team is a full-time job most companies don't want. Metafic runs AI-accelerated engineering pods that ship production software on fixed monthly pricing. I lead engineering as CTO.

Leadnics

Trade-show leads die in business-card piles and spreadsheets. Leadnics is a CRM for people who meet prospects in person: scan a badge or card, AI enriches and scores the contact, and follow-ups fire before you leave the booth.

Open source

What I build when nobody is paying me to

Developer tools I write and maintain in the open. Each one has engineering notes on why it exists and how it works.

MCP Gateway

Connecting N agents to M MCP servers turns into an N×M mess of auth, limits and failures. One secure, observable endpoint in front of all of them: auth, RBAC, rate limiting, caching, OpenTelemetry and circuit breakers.

promptslay

Prompts are code, so why don't we test them like code? Unit tests for prompts: deterministic and LLM-as-judge graders, snapshot baselines, cost tracking, and a CI gate that fails the build on drift.

Built before

Before I knew what I was doing

Before I was building products, I was modifying Android kernels on a Redmi 2. The long road that got me here.

Neural Network from Scratch

A neural network built with nothing but NumPy. Backpropagation and gradient descent written by hand, because using a framework you can't explain is just vibes.
