I build secure multi-tenant SaaS and browser-based computer vision products.

What I'm looking for

I'm looking to build and run production software where I can own architecture, security, data, cloud infrastructure, and measurable outcomes.

I've founded and led engineering for PlanWise, a live multi-tenant SaaS platform that runs architecture firms' enquiries, projects, site operations, approvals, finances, and client portals. As sole engineer, I've built 11 modules, 101 API services, and 102 PostgreSQL migrations with tenant isolation enforced through row-level security and capability-based authorization.

I also built PD Meter, a browser-only pupillary-distance measurement tool using Astro, MediaPipe, OpenCV.js, and Cloudflare Workers. I focus on production architecture, security, cost-aware infrastructure, and measurable engineering decisions.
