Software craft, architected to endure.

I'm a software developer and technical architect with nearly three decades of building systems that scale, ship, and outlast their hype cycles.

01 — About

A builder first,
an architect always.

For almost 30 years I've worked across the full arc of software — from a single curious line of code to enterprise platforms serving millions. My focus is the same as it was on day one: solve real problems with systems that are elegant, resilient, and a pleasure to maintain.

As a technical architect I bridge business intent and engineering reality — translating ambiguous goals into clear technical strategy, mentoring teams, and making the unglamorous decisions that keep products alive for the long haul.

That journey includes seven years at IBM and about twenty years at HPE, where I advanced through developer, technical lead, and technical architect roles across large enterprise programs.

When I'm not architecting for clients, I build small games and utilities for the joy of it. A few of them are below.

02 — Expertise

What I bring to the table.

Three decades distilled into the disciplines I lean on every day.

Systems Architecture

Designing distributed, event-driven and cloud-native systems that stay coherent as they grow — and degrade gracefully when they don't.

MicroservicesEvent-drivenCloud-nativeDDD

Full-Stack Engineering

Hands-on from database to interface. I still write the code, review the PRs, and care about the milliseconds.

Technical Leadership

Growing teams, setting standards, and turning architecture into something people can actually build and own.
