Work Experience

Software DeveloperThmanyah | ثمانية• Freelance

Nov 2025 - Present • Remote, Riyadh, Saudi Arabia

  • Optimized database queries and diagnosed connection pool saturation, reducing critical feed endpoint latency from ~3.9s to ~120ms (~20× improvement)
  • Established performance optimization framework (Measure → Improve → Measure) with documentation and tracking templates
  • Implemented Redis locking to resolve race conditions in critical endpoints, ensuring data integrity
  • Enhanced database tracing and observability using Datadog to improve query execution visibility
  • Designed and rolled out RESTful API endpoints for activity notifications and engagement flows
  • Participated in architectural discussions for cron job migration and backend refactoring strategies
  • Led backend validation alignment to standardize request validation across endpoints
  • Deployed authentication security updates with post-deployment validation
Tech: PostgreSQL / Redis / Datadog / TypeScript / RESTful APIs / Backend Architecture

Selected Projects

Erebus (August 2025) github.com/erebus-sh/erebus
Built a real-time infrastructure platform that lets developers easily connect, publish, and subscribe to live data streams over Cloudflare’s global edge network. Designed a distributed architecture using Durable Objects, WebSockets, and Convex as the real-time data layer. Delivered region-based ULID ordering, edge-queued scaling, cross-region delivery, ephemeral message history retrieval, and a TypeScript SDK for seamless real-time integration..
Tech: TypeScript / Cloudflare Durable Objects / RESTful APIs / WebSockets / Convex / Redis / Queues / Next.js
WasmChannel (June 2025) github.com/v0id-user/wasmchannel
Built an experimental distributed messaging system with Rust WebAssembly, TypeScript, and Cloudflare Workers. Developed a real-time chat application using WebSockets and designed a custom binary protocol as a JSON alternative for high-throughput systems. Benchmarks demonstrated Rust WASM achieving 95.3% faster throughput (34k vs 17k ops/sec). Implemented asynchronous batched writes through edge-based queues for efficient message persistence and scalability, and a RESTFul API for data fetching using pagination.
