Migrations & Modernization

• Improved geographical map application performance by 10x through strategic database transition from MSSQL to PostgreSQL, optimizing processing and data security.
• Optimized budget costs 10 times with zero loss in productivity for the Saudi Arabia company by reimagining the overall infrastructure, eliminating unnecessary services, and relocating from the AWS cloud.
• Migrated the HTTP API from Fiber to Huma v2 — 649 paths and 760 operations — reaching and holding 100% parity between the routes the server registers and the OpenAPI description it publishes.
• Implemented a catalogue‑driven deep‑merge for stored JSON preferences, preventing missing‑key crashes as the schema evolves.
• 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.
• Moved every user‑facing string out of Python into a content tree of 874 files across three languages, after finding dead translations nobody could see were dead and a check silently grading a third of the achievements.

This work is part of what we offer as Backend & API Development, Database Migration & Modernization, Data Governance & Quality, DevOps & CI/CD Automation, Platform & Solution Architecture, Cloud Infrastructure & Migration, Database Administration (DBA) and Database Design & Modeling.
