Iโm a pragmatic full-stack developer with 5+ years of experience specializing in Python (Django, Flask), React, and production REST APIs. I ship reliable, scalable web apps and backend systems with clean PostgreSQL designs and repeatable deployment processes.
Iโve led releases, implemented CI/CD workflows, and designed optimized PostgreSQL schemas for high-read systems. Recent contract work involved debugging large Django codebases, building APIs for dashboards, and delivering frontends for Elixir/Phoenix projects.
I prioritize clean architecture, automated tests, and clear communication so you get reliable code and predictable delivery. My approach is API-first, testable, and focused on user experiences and robust functionality.
My Full Tech Stack (high level)
Frontend: React (hooks, component libraries), JavaScript (ES6+), HTML5, CSS3, Tailwind CSS, Bootstrap, SASS, responsive design.
Backend: Python (Django, Flask, FastAPI) Elixir / Phoenix; RESTful API design, JWT/OAuth auth, WebSockets. Node.js, Express.js, PHP, Laravel. GraphQL, microservices, authentication systems
Data & infra: PostgreSQL (schema design, indexing, migrations), MySQL, SQL performance tuning, ETL & data extraction scripts, Docker, CI/CD. AWS, Vercel, Render, Heroku
RESULTS I DELIVERED
As a Django expert, I supported a large production platform (Founders Network) for ~948 hours, resolving critical bugs, shipping system upgrades, and maintaining a 5.0 client rating.
As an API & Backend expert, I built and shipped core APIs and backend workflows for apprent.com, taskeen.sa, and dietcity.sa, delivering secure subscription and booking flows, reliable background jobs, and maintainable, well-documented endpoints.
As an Elixir / Phoenix & Frontend expert, I delivered UI work ahead of schedule for a Phoenix project. Clients praised my responsiveness and clarity in communication.
