Reliability & Backups

• Led a GIS map application to 10x revenue growth

  Led the software development of a GIS map application, driving revenue growth by 10x and positioning the product as a primary data asset.

• Led 30+ GIS projects from build to support

  Led the development, deployment, and support of over 30 GIS projects, demonstrating expertise in PostgreSQL, Bash, Python, JavaScript, GDAL, ArcGIS, PostGIS, and Mapbox technologies.

• Streamlined CI/CD processes, saving 4,000 hours

  Streamlined CI/CD processes, saving 4,000 hours by introducing automation in software development pipelines.

• Built a test suite across Go, SQL and browser

  Built a layered automated test suite — 981 Go tests, 543 frontend and browser specs, 494 SQL behavioural tests — with mutation testing, property‑based tests and an accessibility gate.

• Ran a continuous security scanning programme

  Established a continuous security programme — code scanning, DAST, dependency and vulnerability checks, SBOM generation, secret scanning and SHA‑pinned actions — alongside 21 written security audits.

• Held the generator to 981 tests and 92% coverage

  Held the generator to 981 test cases at a 92% branch‑coverage floor with warnings treated as failures, and asserted idempotence by running the whole build pipeline twice from an empty file and requiring the second pass to change nothing.

• Adopted Swift 6 strict concurrency over C

  Adopted Swift 6 complete strict concurrency with no actors, bridging a blocking C event loop to the main actor through one producer, one consumer and one ordering — after establishing that a task per event loses the ordering the interface depends on.

• Made six collectors state what they skipped

  Made six reporting collectors state the part of their input they never read — files that stayed shut, probes not installed, journal lines unrecognised — and fitted thresholds to 116 measured samples, after establishing that a blind collection and a healthy host render the same page.

This work is part of what we offer as Technical Leadership & Consulting, Backend & API Development, DevOps & CI/CD Automation, Full‑Stack Product Development, GIS & Geospatial Solutions, Platform & Solution Architecture, Technical Documentation and Custom AI Agent Development.
