The PM
who actually
ships.

7+ years leading mobile and SaaS engineering teams at scale — and a solo portfolio of live AI applications built without a team. I can run your org or ship your MVP. Most PMs can't say both.

Background

Day job
résumé.

Led cross-functional teams of mobile and SaaS engineers — iOS, Android, web, BI — at companies with millions of users. Ran sprints, owned roadmaps, managed stakeholders, and drove real business outcomes.

Then built a portfolio of production apps solo. Not prototypes — live products with real users, real infra, and real monetization. That combination is rare.

Tools I actually
use in production.

I've led engineering teams that use this stack at scale — and I build solo with the same tools. I can implement RAG pipelines, wire LLM agents, design multi-tenant schemas, and ship to production. Everything below has live code behind it.
