// 00_the_thesis
Software got cheaper to build. That changes who wins.
For most of my career, shipping was the bottleneck. That bottleneck is mostly gone — and speed is only leverage if you can aim it.
Eight years across a 25,000-user platform, enterprise systems and my own SaaS taught me where returns actually compound — in the unglamorous parts. Auth that doesn't break. Pipelines that deploy themselves. Data models that hold under load.
AI didn't replace the engineering judgment. It made judgment the whole game. I build the foundations well, then use AI to move fast on top of them — that's how efficiency turns into returns, not just more output.

Corporate-venturing software, idea to live workspace.

VentureKit
A toolkit for running corporate-venturing programs end to end — from defining an innovation challenge to a validated pilot: scoping the problem, scouting and matching startups, guiding the engagement, and producing the business case a board needs to decide on scaling. The structure, milestones and audit trail enterprises expect, in one workspace.

Innovation Ambassadors
One workspace for internal corporate innovation. Employees submit ideas, ambassadors score them, and the innovation team decides — audit-ready from intake to funded initiative. It replaces the usual sprawl of email threads, spreadsheets and sticky notes with a single accountable pipeline.

// 04_how_i_work
From a vague idea to something live.
01
scope
Start with the why
Before a line of code, I dig into the goal, the users and the actual problem — including the edge cases nobody mentioned. Better questions early kill the weak ideas cheaply and sharpen the one worth building.
02
design
Move fast, but with intent
From wireframes to working UI, fast. The point isn't pixels — it's the experience and the flow. You see something real early, not a deck.
03
build
Ship it clean
Frontend, backend, AI integrations, native apps — whatever it takes, shipped clean and scalable. You get regular demos and stay in the loop the whole way, no black box.
04
run & iterate
Launch is a checkpoint, not the end
I build service-as-software: the workflow runs itself, but the human touchpoints stay. After launch I keep working with you to refine, grow and earn the next result — not hand over a repo and disappear.
// run
