Zia Ur Rehman

I’m a Full Stack Ruby on Rails Engineer with 4+ years building and scaling production Rails 5/7/8 and React systems for global remote teams. I modernize legacy Rails monoliths, then ship user-focused features end-to-end with TDD (RSpec), CI/CD, and performance optimization.

Across my work, I’ve architected real production platforms—like a tri-party software escrow platform shipped from scratch to production on Rails 8 with Hotwire, PostgreSQL, Solid Queue, and RBAC, plus bilingual Arabic/English UI with full RTL support. I also design service-oriented REST and GraphQL APIs, including release-approval pipelines with audit-ready state machines and compliance-minded logging.

I thrive in distributed Agile teams across US and UAE timezones, and I’m comfortable integrating complex external systems—from CRMs to payment, messaging, and healthcare APIs. Today, I’m focused on building reliable multi-tenant products (including my Pakistan-based agency work and live SaaS), where clean domain boundaries, secure integrations, and measurable impact matter.
