Muhammad El Sayed 👋

Backend Software Engineer building production APIs, data-intensive systems, and open-source developer tools.

I build systems that remain fast and correct under load—from multi-tenant SaaS platforms on AWS to ingestion pipelines where throughput is the product. I also create tools that make AI-assisted engineering more rigorous.


Featured open source

A Claude Code plugin that turns Claude into a guide, not an autocomplete.

Claude guides, verifies, and remembers. You write every solution-bearing line.

Learning Mode helps engineers learn unfamiliar technologies by making them attempt, reason, implement, and test for themselves. It provides progressive hints, verifies technical claims against primary sources, and preserves progress in resumable learning journals.

Includes a read-only documentation-verifier agent. Free, open source, and MIT-licensed.

High-throughput log-ingestion platform.

Scaled ingestion from 6,071 to 17,255 requests/second—2.8× higher throughput—using Node.js cluster mode, worker threads, and Redis Streams.

Rewriting the consumer in C++ delivered another 2.7× improvement while reducing peak CPU usage by 75% and memory consumption by 80%.

Built with Node.js, C++, Redis Streams, ClickHouse, gRPC, OpenTelemetry, and Docker.


Production systems

Publishing SaaS

Live, multi-tenant, Arabic-first publishing platform built with Django, Django REST Framework, and PostgreSQL.

  • Stripe subscription billing with webhook-driven state synchronization
  • Presigned uploads to Cloudflare R2
  • AWS ECS/Fargate deployment on ARM64
  • RDS, Valkey, Application Load Balancer, and SES

Sindion Technology

Production property-management platform.

  • Reduced API response times by 65%
  • Eliminated 93% of redundant database queries
  • Optimized Django ORM access patterns and PostgreSQL composite indexes
  • Built PostGIS-to-GeoJSON APIs for real-time boundary visualization
