NJBSoft Compliance Software Management (secure compliance platform for inspections, permits, documents, and public-sector workflows) NJBSoft is a compliance management platform used to unify inspection data, permit records, operational workflows, and documentation in one secure system. I helped build the core web application and backend workflows around document access, inspection records, reporting, and role-based permissions. The important overlap here is tenant-safe compliance data: every API request needed clear organization/project context, so one client’s records could not leak into another client’s workspace.

Cover image for Timewell is a consumer platform
Timewell is a consumer platform where customers build hardbound photo books, record voice stories attached to individual photos, and then scan unique QR codes printed inside the book to listen back - reliably, years later. I architected and built the full stack: the QR generation and resolution system that maps each code to a specific page and user, the media upload pipeline for audio and images, the admin dashboard for order and content management, and the public-facing mobile experience optimized for a cold-open scan (no app install, instant load).
