About
How I build.
I'm Abdel-Rahman Mohamed Saied (عبدالرحمن محمد سعيد) — a Technical Lead and Staff-level Backend Engineer whose path started with desktop apps, moved into backend platforms, and grew into owning production systems, distributed data flows, engineering teams, and AI-powered products.
Summary
Professional Overview
I began by shipping desktop software end to end, where reliability was visible in every user workflow. That foundation shaped how I later approached backend systems: start with clear domain boundaries, keep operations observable, and design for the people who will maintain the system after launch.
Over the last 6+ years, that scope expanded into production-grade platforms across social intelligence, transportation, hospitality, AI, cybersecurity, and talent marketplaces. My primary stack is Python and Django, used for systems processing 5M+ records daily, geospatial trip management, multi-tenant hotel operations, and high-throughput async workflows. I also engineer in Go, including Fendix, an open-source DAST + SAST scanner built around correlated findings and zero telemetry.
Today my strongest work is at the intersection of backend architecture, product ownership, and hands-on technical leadership: leading 13 engineers, improving throughput by 3x, reducing latency by 25%, cutting deployment cycles by 40%, and turning AI capabilities into production features with measurable business value.

FAQ
Common Questions
Who is Abdel-Rahman Saied?
Abdel-Rahman Mohamed Saied (عبدالرحمن محمد سعيد), also written Abdelrahman Saied or Abdelrahman Saeed, is a Technical Lead and Staff-level Backend Engineer based in Riyadh, Saudi Arabia. He specializes in distributed backend systems, AI infrastructure, and hands-on engineering leadership, and is the creator of Twiscope, Fendix, and MURI.
What is Twiscope?
Twiscope is an Arabic OSINT social intelligence platform built by Abdel-Rahman Saied. It processes more than 5 million data points daily across Twitter/X, Instagram, TikTok, Google, and news sources, with ML-driven sentiment analysis, trend detection, and real-time alerting. It is live at twiscope.net.
What is Fendix?
Fendix is an open-source API security scanner written in Go, created by Abdel-Rahman Saied. It runs DAST and SAST engines together and only raises a build-failing alert when both independently flag the same vulnerability — cutting false positives by roughly 70%. It ships as a single signed binary and is available at fendix.dev.
What is MURI?
MURI is a student transportation platform engineered by Abdel-Rahman Saied, with dedicated apps for clients, drivers, and admins, a modular Django API, PostGIS geospatial routing, and real-time WebSocket trip tracking. It is live at muri.sa.
What are Abdel-Rahman Saied's key engineering achievements?
He has led 13 engineers as a Technical Lead and Staff-level Backend Engineer; engineered Twiscope, which ingests 5M+ data points per day across five social networks; improved production backend throughput by 3x; reduced system latency by 25% through Redis caching and async task optimization; cut deployment cycle time by 40% through CI/CD restructuring; and maintains 99.9% uptime across the production systems he owns.
