Highlight Project

Python · psycopg2 · PostgreSQL · Docker · WSL2 · SQL

  • Data-Automation-Pipeline-V1 — End-to-end data pipeline that uses Python connection drivers (psycopg2) to reach through the network layers of a local, Docker-hosted PostgreSQL instance and fully automate the database lifecycle.
  • Containerized database host — PostgreSQL runs inside a Docker container with mapped ports and persistent volumes, so the whole environment can be torn down and rebuilt identically on any machine.
  • Network-layer connection — Python connects across the container's network boundary through psycopg2, handling host/port mapping, credentials, and transactional cursors from WSL into the container.
  • Automated drops & structural migrations — Scripts drop stale objects and apply schema migrations in order, creating tables, keys, and constraints so the relational model is rebuilt idempotently on every run.
  • Batch uploads — Source records are loaded in batches inside transactions, so a failed batch rolls back cleanly instead of leaving partial data behind.
  • Analytic SQL cost calculations — Aggregation queries calculate cost metrics directly in the database and return reporting-ready results to Python.

Roles

2 data-focused roles

  • Data & Automation Engineer (Independent) · 2025 - Present — Built Data-Automation-Pipeline-V1: containerized PostgreSQL with Python-driven migrations, batch loads, and analytic SQL.
  • Engineering Technician, Hydro Precision Tubing (Rockledge, FL) · 2021 - 2026 — Integrated measuring equipment with analog/digital I/O for temperature, flow, and pressure data, then used those readings to drive process and quality fixes.
