Biography

Developer Profile & Background

I'm a Senior Backend Engineer & Technical Lead with more than 2 years leading production Laravel systems for a Kuwait-based startup, plus contract work with a Y Combinator-backed AI company.

#What I do best:

Architect multi-tenant SaaS platforms with financial-grade data integrity — atomic transactions, pessimistic locking, and idempotency for payment systems


Integrate complex third-party APIs, including reverse-engineering an undocumented Shopify GraphQL endpoint to save a client 300 KWD in fees


Optimize legacy systems for scale — cut MySQL query latency by 93% (1s → 70ms) through N+1 diagnosis, eager loading, and Redis caching


Build multi-gateway payment integrations (Hesabe, MyFatoorah) using clean, testable design patterns


DevOps & legacy maintenance:

Own full CI/CD pipelines end-to-end, from Git workflow through deployment on Ploi


Migrated legacy deployment workflows to containerized environments (Docker/Podman), setting up webhook-driven auto-deployment to cut manual release overhead


Refactored a monolithic legacy codebase into a Service-Oriented Architecture with proper Dependency Injection and DTOs, improving long-term maintainability without service disruption


Run production monitoring via Laravel Telescope and Nightwatch to catch performance regressions and bugs before they hit users


Recent work:
Led backend architecture for Fooderz, a multi-tenant B2B SaaS ERP for food/kitchen operations — RBAC via Spatie, subscription billing, and pessimistic locking for financial consistency. Also built a WebRTC signaling layer for a real-time calling feature, and shipped production FastAPI work for a YC-backed AI startup within days of onboarding.

I write tests for the logic that actually matters (PHPUnit/Pest on financial and mathematical code), and I'm comfortable being the only backend engineer on a project — from database design through deployment and ongoing maintenance.
