About Bobby Whitehead

I’m a data driven backend engineer who turns high volume market streams into clean, query ready datasets and dependable APIs. Across a twenty year journey from on prem DBA and server admin to cloud architect I have built Python ELT pipelines, tuned SQL Server at scale, and delivered event driven services that keep business critical data moving around the clock. https://github.com/Phrendo https://bobbys.site/ Core Highlights • Cloud and Data Architecture: Built a real time options analytics platform with a Parquet and JSON lake plus a SQL Server warehouse, fed by Python asyncio and Polars pipelines that ingest gigabytes of Schwab, TDA, DataBento and TastyWorks ticks each day. • WebSocket ELT Pipeline: Captured live market ticks via WebSocket, stored them in Parquet for historical analysis, and mirrored them to Redis for instant trading decisions. • Database Engineering: Applied index tuning, partitioning and query rewrites that cut compute costs and doubled report speed for finance and operations teams. • DevOps and Observability: Deployed systemd services, exported metrics to Prometheus and Grafana, and centralized structured logs with journalctl for rapid root cause analysis. • Leadership: Directed cross functional teams, mentored engineers, and guided the migration from on prem clusters to Azure hybrid environments without downtime. I thrive where data volume, performance and reliability meet. Whether rescuing an overworked SQL cluster, wiring an event bus, or steering a team through schema evolution, I can architect the system, write the code, and speak the language of the business.
