Josh Zimmerman
I build complete technology products across software and hardware. I develop user interfaces, backend services, databases, and production infrastructure, taking projects from initial concept through testing, deployment, and ongoing operation.
For hardware, I translate product needs into technical requirements, select and specify components, design system configurations, and test for performance, reliability, and compatibility.
I use practical, right-sized solutions—from lightweight Python services to multi-tenant Next.js and PostgreSQL platforms and integrated hardware-software systems. My work supports real users, real data, and real-world operation, and I take responsibility for understanding, validating, and maintaining what I build.
Projects
Production software I've built and operate. Click any project for details.
Midgarda
View project →Multi-tenant field service management platform — dispatching, inventory, customer management, and billing in one system, with web, desktop, and mobile clients.
HiveBuzziness
View project →Apiary operations platform built for a commercial beekeeping operation — roughly 5,000 hives across 100+ yards. Field crews log work with photos and GPS; a scheduling engine computes which yards are due for what.
BFhub
View project →Internal operations hub combining a project tracker with a live BlueFolder work-order dashboard — written in pure Python standard library, no framework, no external dependencies.
SnapBar
View project →Native desktop screenshot app for macOS and Windows with an annotation editor built for physical-security site surveys — 40+ hand-drawn device stamps for cameras, access control, fire, and network equipment, with project files that open on either platform.
Card Games
View collection →A growing collection of card games playable right in the browser — each one a single hand-crafted HTML file with zero dependencies. First at the table: Texas Hold'em against AI opponents, with a learning mode that shows live win odds while you play.
