WORK
I take products from zero to production - product decisions, working code, and delivery in one person. Fifteen years of product management across ad tech, e-commerce, and SaaS, now with AI leverage: I ship the things I used to write specs for. FastAPI, Rails, React, Cloudflare Workers.
Available for
0-to-1 builds
You have a product idea and no team. I run fixed-scope discovery, then ship weekly increments to production - handover or ongoing. Product, code, and delivery in one contract.
Personal AI consulting
One-on-one, not a corporate workshop. I'm further down the Claude Code and agents road than most people in tech - I'll set up your environment, show you what's actually possible, and automate the things you still do by hand.
Show me the thing you'd say "I bet AI can't do that" about - and I'll prove you wrong.
Wallet pass advertising and loyalty through Apple and Google Wallet. Three founders, no outside funding. I own product and write production code: the FastAPI backend alongside the lead engineer (~27% of commits) and the merchant frontend end-to-end - magic-link auth, observability, CI. First paying pilot live with a retail chain in Poland; accepted into WPP's startup accelerator, which puts Satori in front of three major agency networks.
Ad tech consulting
Forecasting tool for a European ad tech platform: an 11-week fixed-scope pilot where I managed delivery of four ML prediction models into the production forecasting API, ZIP-level geo filtering, and an embeddings-based audience segment recommender. 13 production releases, every deliverable accepted.
DSP rescue for an APAC client: took over an at-risk build with broken client communication, restored trust with a structured cadence - daily async updates, weekly reports - and managed delivery of 12+ features: exchange integrations, pacing, dynamic CPM, multi-region infrastructure. Closed it with a retrospective across 681 tracked issues that gave leadership the real cost picture.
A film director friend was tracking funding deadlines in spreadsheets and missing them. We built Open Call together - she's user-zero, I'm the team. 108 manually verified film and art programs, saved-filter email subscriptions, two-stage deadline reminders. Self-hosted with Docker and a Cloudflare Tunnel. From idea to a live product, a few evenings at a time.
build
The PM operating system I run my own work on: Claude Code plus structured markdown - briefs, status files, decision logs, skills that generate stakeholder updates. Dogfooded across founder work and client consulting at the same time, then extracted into a public framework. If you hire me, this is how your project gets run.
Coach site + AI assistant
Current freelance engagement: rebuilding a solo coach's website and adding an AI assistant. Discovery and competitor research done, stack decided, build underway.
The chat bubble on this page is a real product, not an embed: a Cloudflare Worker with SSE streaming, D1 for conversations, KV rate limiting, and Turnstile against abuse. Ask it about my work - it knows.
