/ 01 — What I do

Good systems are a team sport.

I'm a hands-on software architect, fullstack developer, and former CTO with a product mindset. I've spent the last decade modernizing monoliths, scaling real-time data platforms, strengthening observability, and helping distributed teams ship with confidence. Today, I partner with founders and leadership teams as a fractional CTO when they need senior technical direction without the overhead of a full-time executive.

01

Fractional CTO

Executive-level technical leadership for teams that need clarity, prioritization, and a pragmatic path from strategy to shipped product.

02

SRE & DevOps

I make production predictable with observability, resilient architecture, safe deployments, and the right signals for fast decisions.

03

AI workflows

I design and build practical AI workflows that automate operations, augment teams, and create leverage without adding needless complexity.

04

Product engineering

I connect technical decisions to customer outcomes, shipping fullstack products without creating tomorrow’s emergency.
