# Karl Hill

> 25+ years shipping mission-critical software — NASA Earth science, flood mapping, and aerospace platforms at Jacobs.

I architect systems, lead teams, and ship software that matters — from disaster-response platforms at NASA to mission-critical aerospace systems at Jacobs/BlackLynx.

## Case studies

- [NASA Earth Observatory](https://karlhill.com/work/nasa-earth-observatory): A flagship NASA science communication platform serving 1.5M+ monthly visitors — rebuilt for editorial velocity, performance, and long-term maintainability.
- [Flood Mapping System](https://karlhill.com/work/flood-mapping-system): Near real-time flood inundation mapping from satellite data — built for disaster response when latency is measured in hours, not sprints.
- [Direct Readout Laboratory](https://karlhill.com/work/direct-readout-laboratory): A scientific data hub ingesting multi-instrument satellite streams and distributing geophysical products to a global network of ground stations.
- [ESSCOR](https://karlhill.com/work/esscor): A discovery portal unifying archival and near real-time remote sensing holdings into a searchable, standards-compliant catalog.
- [InformedDNA Platform](https://karlhill.com/work/informeddna-platform): A clinical genomics workflow platform that unified case management, counseling routing, and billing across distributed care teams.
- [Finium](https://karlhill.com/work/finium): An enterprise managed security services platform that scaled client operations across a national carrier network.

## Writing

- [What 20 Years Taught Me About Release Governance](https://karlhill.com/blog/release-governance): Release governance is not bureaucracy. Done well, it is how engineering protects trust — how teams make sure what they build can actually be deployed, supported, reproduced, explained, secured, and operated.
- [The Unglamorous Work of Leading Engineering Teams](https://karlhill.com/blog/leading-teams): High-performing teams are rarely the result of a single brilliant hire. They are the product of consistent standards, honest feedback, and the quiet operational work that makes delivery predictable.
- [Why Automation Matters More When the Data Is Mission-Critical](https://karlhill.com/blog/science-data-automation): In Earth science and disaster-response systems, manual workflows do not just waste time — they delay decisions. Automation is how you turn raw sensor streams into something operational teams can actually use.
