Independent software & AI engineering

Software and AI that survive production.

Two decades building systems where downtime was never an option — for teams that move money, messages, and machines. Now you can put that same engineering to work on yours.

01 · What I build

Systems that hold up when it matters.

Most of the work is the unglamorous part that decides whether software actually survives contact with the real world.

Build 01

Production systems

Backends and services designed for real load — with the testing, observability, and operational care that keep them running long after launch.

Apply 02

AI, put to work

Language and ML models integrated into real products: verifiable, human-in-the-loop, traceable to a source — not a demo that never ships.

Design 03

Architecture & cloud

Event-driven, distributed, cloud-native design across the major clouds — shaped to scale and, just as important, to be operated.

Fix 04

Rescue & scale

Stepping into complex, mission-critical systems to find the bottlenecks, harden the weak points, and make them fast and dependable.

02 · How I work

A few rules that don't bend.

Twenty years around mission-critical software leaves you with strong opinions about what actually ships and stays shipped.

01

Ship, don't shelf.

Working software in production beats a perfect plan on a slide. The goal is always something real, running.

02

Human in the loop.

AI proposes; people decide anything with consequences. Automation earns trust one verified step at a time.

03

No black boxes.

Every result traces back to a source you can check. If you can't explain it, you can't rely on it.

04

Built to be operated.

Tested, observable, documented. Software is judged on the quiet months after launch, not the demo.

03 · Background

Two decades in engineering-led teams building systems that couldn't afford to fail — across financial services, telecommunications, and large enterprise.
