Looking after the database

Selected work demonstrating this service.

• 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.

• Wrote 1,000 RBAC rules to secure Linux servers

  Enhanced data security by implementing 1,000 RBAC rules for developers, application instances, PostgreSQL, MS SQL, and other Linux servers, preventing unauthorized access; documented with Ansible automation.

• Accelerated PostgreSQL performance by 10x

  Accelerated PostgreSQL performance by 10x via strategic indexing, partitioning, and query optimization, enhancing database efficiency for user, tenant, geospatial, and time‑series electrical data.

• Automated 100 critical data backups using Barman

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

• Automated data processing in Python and PL/pgSQL

  Automated data processing tasks using Shell scripting, PL/pgSQL, Python, and Transact‑SQL, increasing productivity and efficiency.

• Engineered 600 PL/pgSQL ETL/ELT pipelines

  Engineered 600 PL/pgSQL‑based ETL/ELT pipelines to streamline complex data processing workflows across multiple PostgreSQL development and production environments.

• 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.

• 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.
