Rockstar🎓
Top SchoolTimo Von Holtz is a software engineer with 13 years’ experience building reliable, measurable systems where uptime, latency, and auditability matter. He has driven platform and product work across healthcare and developer-facing startups, from scaling hospital deployments and HL7/DICOM integrations to building APIs and usage-based billing systems. Comfortable across backend, auth, and systems work, he’s implemented authzed-based permission models, Lago/Stripe billing, and internal Haskell tooling including an OAuth2 server. Timo blends pragmatic engineering with a focus on observability and correctness, favoring solutions that can’t be “faked.” Based in Houston, he pairs a Master’s in Computer Science with hands-on experience converting legacy stacks to scalable, auditable platforms. An early adopter of formalized version control and build automation, he brings both operational rigor and a taste for elegant, verifiable systems.
