Jacobs is current. Public NASA systems: Flood map Find Data

Jacobs · 2025–present

Engineering mission software at scale

Hands-on engineering and technical delivery on a simulation program: roughly 20 repositories, three environments, and partner teams. Delivery gates, portable messaging, and stronger tests are in use; coaching is part of the work.

Flood Mapping System

Python and Docker software for processing and distributing satellite-derived flood maps on AWS. Built to support near-real-time Earth observation products. The live map is public; a GeoHorizons paper describes the system.

NASA LAADS Find Data — product, time, location, files, and review-and-order wizard for MODIS and VIIRS granules.

NASA · 2017–2025

LAADS DAAC

Find Data search, ordering, and near-real-time access to NASA MODIS and VIIRS satellite data. Web systems shipped through GitLab CI/CD and Kubernetes alongside existing Perl services.

How software gets delivered

Software other people depend on, then the checks, integration, and release around it. Select a stage.

Build Code Verify Integrate Release Quality Testing Security Environment Readiness

Build

Packaging so the same change rebuilds elsewhere.

uv Docker packaging

Code

Services, libraries, and interfaces other people depend on.

Python TypeScript Java

Verify

Quality, tests, and security checks on the change.

Ruff mypy pytest coverage security scanning

Integrate

Contracts between services: APIs, messages, and schemas.

APIs messaging schemas distributed services

Release

Promotion through environments until the change is operable.
