Systems that keep running.
From architecture to production.
I'm Zayd, a backend and infrastructure engineer based in Damascus. I design, build and run the backend systems products depend on, for startups, SMEs and international teams. I work in three ways: building a system end to end, acting as a technical partner for founders, or leading backend and infrastructure part-time for small teams.

// Working together
Three ways to work with me
Build
When you need it
A defined system: an API, a platform, a migration
What I own
Delivery from proposal to production
Technical partner
When you need it
A founder with an idea and no technical lead
What I own
Architecture, build decisions, the first version
Part-time backend lead
When you need it
A small team without a senior backend or infra person
What I own
Direction, reviews, infrastructure, hiring input
// Selected work
A selection of systems I built and run
These are selected projects, not everything I have worked on. Each has a case study: the problem, what I built, and what changed.

Promotion and leadership
Joined as a Backend Engineer in April 2025 and was promoted to Backend & Infrastructure Lead in early 2026. Lead a team of 2–3 engineers and run sprint delivery.
Architecture ownership
Own Syncrow's system architecture and make technical and infrastructure decisions across the platform. Run the design review meetings where designs are approved before implementation.
Consolidating on AWS with Terraform
Moved the dev and staging environments from Azure to AWS and closed every Azure resource, so dev, staging and production now run on AWS, 100% defined as infrastructure-as-code in Terraform, with the IaC repository under CI.
Platform simplification
Replaced the Firebase real-time database with Redis for storage and WebSockets for real-time communication, cutting monthly infrastructure costs by 61.5% and reducing third-party dependencies. Firebase Cloud Messaging (FCM) is still used for push notifications.
White-label, multi-tenant platform
Designed and built the foundation that lets one codebase power multiple brands, with a tenant-aware backend and automations engine and build-time branded mobile apps. It was built for a customer who asked for their own branded application, which is about to launch. New brands can be onboarded without forking the codebase.
Telemetry and PostgreSQL at scale
Moved device telemetry to TimescaleDB on top of PostgreSQL after one large log table made analytical queries slow, choosing a fix that needed minimal migration and cutting query time by about 50%. Run PostgreSQL at the 100GB+ scale and keep it under control.
AI integration
Lead backend integration of AI-driven automation proposals and the consolidation of the platform's authentication into a single system.

// About
Systems from architecture to production
I'm a backend and infrastructure engineer based in Damascus. I lead backend and infrastructure for an IoT platform, where my team builds the system that connects devices to the apps people use every day. Long before that, I was running my own self-hosted infrastructure, and I co-founded Moushref, a platform that lets schools go cashless with NFC bracelets while giving parents a clear view of their children's spending.
I work with startups, SMEs and international teams in three ways: building a system end to end, acting as a technical partner for founders, or leading backend and infrastructure part-time for small teams. Every engagement starts with a written proposal, in English or Arabic, so you know what will be built, when, and for how much.
I hold a B.Sc. in Software Engineering from Damascus University.
