  Seeking: Senior Product Engineer with product design ownership (permanent preferred; open to substantial contract work)

I turn unclear product problems into useful, well-designed software. I talk to customers, turn what I learn into product and technical specs, design the workflows and interface, build the system, then help launch, market, and support it. That breadth is my strongest skill: it keeps the customer problem in view throughout.
At Flowstate, I took a workforce-planning SaaS from blank repo to paid pilot in 10 weeks as sole engineer-designer. I've since owned product design, backend, mobile apps, Stripe Connect payments, AI-assisted listing tools, and infrastructure for a US trading-card marketplace.
I use and evaluate new AI models and coding workflows to make product development faster, while preserving quality through type safety, tests, CI, review, and product judgement.
I'm looking for a team that uses AI coding tools seriously, values strong product design, and keeps product builders close to customers.
