Four systems, and what they taught me.

One shipped to production during an internship, one storage engine written from the disk up, one controlled study, and one retrieval service. Each page covers the problem, the decisions, and the measured result.

  1. 01

    Built and shipped a FastAPI credit-claim service replacing a manual credit-grant workflow for a 500+ developer portal, collaborating with product and operations stakeholders.

  2. 02

    Designed REST APIs and PostgreSQL data flows for credit claims, validation, and reconciliation, improving reliability and reducing manual intervention in a production workflow.

  3. 03

    Root-caused duplicate credit grants by tracing state across services, then built Python reconciliation scripts to validate records end to end and eliminate a recurring manual audit step.

  4. 04

    Profiled PostgreSQL queries and applied indexing and query restructuring, reducing average query latency by 30% across production REST endpoints.

  5. 05

    Used Git-based development, code reviews, CI/CD, debugging, and incremental delivery to ship backend changes and resolve production issues.

Curious how any of it was built?
