Backend Engineer | DevOps & Infrastructure

Remote - KSA

Architected and deployed message-queue-based microservices (Kafka/RabbitMQ) to decouple service dependencies, boosting system resilience and enabling independent scaling of high-load components. Built high-performance RESTful APIs using NestJS and TypeScript — secured with JWT/OAuth 2.0 authentication, designed for horizontal scalability, and integrated with CI/CD pipelines for zero-downtime releases. Configured Prometheus and Grafana monitoring dashboards for production microservices — established alerting rules for API latency thresholds and container anomalies, reducing mean time to detect (MTTD) incidents.

Backend Engineer

Remote - KSA

Redesigned backend microservices with NestJS and PostgreSQL, cutting API response time by 30% through query optimization, selective indexing, and restructured service boundaries. Conducted systematic backend performance profiling and resolved critical bottlenecks — reduced peak-load error rate by up to 60% and achieved consistent API throughput under production traffic spikes.

Backend Engineer

Dubai

Refactored backend microservices from a monolithic pattern to a modular architecture using AdonisJS and PostgreSQL, cutting release cycle time by 25% and reducing inter-service coupling. Eliminated N+1 query anti-patterns and redesigned critical API endpoints for load-balanced environments — reduced average query execution time by up to 40% across the most database-intensive service operations.

Backend Engineer

Homs, Syria

Built real-time backend features (live chat, notifications, live data sync) using Socket.IO, increasing active user engagement by 25% within 60 days of launch. Optimized PostgreSQL queries and introduced a Redis caching layer — reduced backend response latency by up to 35% and improved API throughput under concurrent user load. Implemented Elasticsearch-powered full-text product search for a production e-commerce platform — configured custom analyzers and optimized query DSL, achieving sub-100ms search response times across large product datasets.

Freelance Backend Engineer — 8+ Clients across Oman, Turkey, KSA, UAE, and Syria

Remote

Delivered 8+ custom backend projects across 5 countries — reduced average server response times by up to 40% through Redis caching, index optimization, and query tuning tailored to each client stack. Designed and optimized multi-tenant PostgreSQL schemas with proper data isolation boundaries, improving retrieval efficiency and eliminating cross-tenant data leakage risks.
