Reliability & Backups

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

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, Data Pipeline Development (ETL/ELT) and Product Strategy & Requirements.
