Systems Architecture
Relational data models, state machines, and audit trails — built so data integrity holds under real-world load.
Bradley Baumann
I specialize in calibration and internal management systems, where data integrity and user experience both have to be right. I also take on custom web applications and freelance work.

I write the code across the stack — database schema, application logic, and the interface on top. Stitching features together from separate tools gets you there faster, but it's what makes systems hard to maintain later.
Reliable architecture needs solid schemas and clear interfaces. I design data models that protect integrity, then use UX to keep complex data entry simple for the people actually doing it.
Years working inside a NATA-accredited calibration lab under ISO 17025 — I understand measurement uncertainty, audit trails, and the data rigor those workflows demand.
Past client and freelance web projects. My current focus — a calibration management system I'm building now — will land here as a full case study soon.
Alongside my calibration systems work, I take on freelance web development — from full builds to fixing what's already there.
Relational data models, state machines, and audit trails — built so data integrity holds under real-world load.
TypeScript, React, and Supabase/PostgreSQL — from schema to interface, shipped end-to-end.
Operator-first interfaces that make dense, complex workflows fast and error-resistant.
Moving legacy, manual systems to modern cloud infrastructure — zero data loss, from an active migration to a ground-up rebuild.
Architecture reviews, performance tuning, and workflow automation for growing businesses.
