A developer who wants the whole picture.

I started on internal ERP and CRM tooling. Over the past four years I have shipped government visa platforms, LMS and coaching apps, expert marketplaces, and multi-tenant SaaS builders.

The work I like most is the part where a vague requirement turns into a schema, a boundary, and a decision someone can argue with.

Looking for a full-stack engineer who ships.

Open to remote and hybrid roles. If you have a system to build, I would like to hear about it.
