Product Leader Turned Developer

I build products people actually use

After 15 years as a product executive — leading teams at Crunchyroll, Fandom, and eBay — I now build full-stack apps end-to-end using AI-assisted development. Stanford MBA meets modern engineering.

What I Do

Product strategy and hands-on development from a single person. I bring 15 years of leadership to every line of code.

Product Strategy

15 years as CPO/CTO at companies from startup to $1B+ scale. I help define what to build, not just how to build it — roadmaps, prioritization, and go-to-market.

Mobile Apps

Native-quality iOS and Android apps with Flutter. Live streaming, camera integrations, real-time data, social features, App Store deployment.

Web Platforms

Responsive web apps with Next.js and React. SaaS dashboards, admin panels, marketing sites, payment integrations.

Backend & Cloud

FastAPI backends on Google Cloud — REST APIs, Firestore, BigQuery, Cloud Run, Cloud Tasks, CDN, scheduled jobs, AI integrations.

AI Integration

Claude and GPT-powered features — content generation, classification, autonomous agents, chat interfaces, hybrid scoring engines.

Team & Process

Experimentation frameworks, A/B testing, agile workflows, user research. I've scaled product orgs from 5 to 150+ people.

Products I've Built

Two production platforms built end-to-end — from system design to app store submission.

Onda

About Me

For over a decade I was a Chief Product Officer — leading product organizations at companies like Crunchyroll (through its $1B acquisition by AT&T), Fandom (350M+ users), HODINKEE, and TRX. Before that I managed products at eBay, launched GarageBand at Apple, and earned my MBA from Stanford.

In 2023 I made a bet: that the best way to build great products is to build them yourself. Using AI-assisted development tools, I started shipping production software — Python, Flutter, React, cloud infrastructure. Not prototypes. Real products with real users.

The result is a rare combination: 15+ years of product strategy and leadership paired with hands-on engineering. I don't just build features — I understand the business context behind them, the user problems they solve, and how to prioritize what matters.
