Reliability & Backups

• Built the company's first observability dashboard

  Developed and launched the company's first observability dashboard, providing real‑time system performance insights and data visualization on the large office TV.

• Ran 100 PostgreSQL, MS SQL, BigQuery warehouses

  Architected, created, and managed 100 PostgreSQL, MS SQL, and Google BigQuery data warehouse databases with primarily GIS and time‑series data, optimizing performance and scalability.

• Ran 10 PostgreSQL and MS SQL servers on Ubuntu

  Designed, deployed, and maintained 10 PostgreSQL and MS SQL servers on Ubuntu Linux VPS, ensuring optimal server performance and reliability.

• Automated GIS SaaS deployment with GitHub Actions

  Automated GIS SaaS application deployment, data processing, and reporting system using GitHub Actions CI/CD, Python, Bash, and SQL.

• Automated delivery of 20 GIS data pipelines

  Automated delivery of 20 GIS data pipelines and app data ETL processes, streamlining infrastructure automation and reporting.

• Automated 100 critical data backups using Barman

  Automated 100 critical data backups using Barman, Google Cloud, Bash, and Python, ensuring data integrity across databases.

• 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.

• A mapping product, carried end to end

  Architected, developed, implemented, supported infrastructure, data processing, and the map application for 2 years non‑stop without any weekends, holidays, or vacations, 10–14 hours a day.

• Implemented backups and disaster recovery as code

  Configured database backup retention as infrastructure‑as‑code, then audited the recovery position and documented the restore procedure — naming the remaining gaps rather than leaving them to be found during an incident.

• Moved slow work onto a River job queue

  Moved slow work off the request path onto a River job queue — 15 worker modules, 8 scheduled tasks and 20 pg_cron jobs — so a request returns while the work behind it carries on.

• 1,022 migrations behind a schema drift gate

  Kept the schema honest across 1,022 migrations with a CI gate that builds the database both ways — a fresh install, and an install plus every migration — and fails when the two disagree.

This work is part of what we offer as Database Administration (DBA), GIS & Geospatial Solutions, Data Pipeline Development (ETL/ELT), DevOps & CI/CD Automation, Site Reliability & Monitoring, Backend & API Development, Backup & Disaster Recovery and Database Design & Modeling.
