Digital systems, human pace

Strategic engineering, AI enablement, and product leadership — without the chaos.

I help thoughtful teams, engineers, and ICs design, ship, and stabilize software systems — from AI-powered tools to core product platforms. Clear architecture, maintainable code, and a steady delivery rhythm.

Services

What we build, fix, or clarify together.

Engagements are scoped to your current season: early product validation, scaling systems, untangling complexity, or engineers seeking mentorship.

AI enablement for real teams

Design and integrate AI workflows aimed at reducing cognitive load rather than adding noise — from internal tools to customer-facing products. AI-assisted UI generation and deterministic prototype workflows when they fit.

Strategy · Rapid prototyping · Guardrails · Team onboarding

Systems & product architecture

Clarify your system boundaries, data flows, and product surface — including microservices and API design — so future changes are easier to reason about.

Microservices · APIs · Roadmaps · Migration planning

Hands-on engineering & reviews

Ship key features or refactors with a partner who writes clear code, documentation, and tests — and transitions knowledge so your team can maintain the work. Pair with engineers and ICs who want to grow.

Product & leadership advisory

Support for founders, PMs, engineering leads, and engineers or ICs seeking mentorship — navigating growth, focus, and team dynamics. Help reinforce product-thinking and extend impact.
