Wahaj User
@wahajuser
Full-stack software engineer specializing in Laravel, microservices, and high-throughput systems.
What I'm looking for
I am a software engineer with 5+ years building full-stack web applications and scalable backend systems. I work across PHP MVC frameworks (notably Laravel), JavaScript, and SQL/NoSQL databases to deliver production-ready features.
I have delivered 30+ client-facing web apps, integrated Elasticsearch to cut P95 load times, and implemented RabbitMQ notifications, WebSocket streaming, AWS Lambda transcription, and Stripe payments to accelerate delivery cycles.
I built REST APIs and geofencing microservices, and developed a high-throughput GPS tracking service in Go that handled 1,000+ concurrent streams while reducing query latency significantly. I design event-driven services with retry and dead-letter handling to ensure reliability at scale.
I focus on query optimization, caching (Redis), and proper indexing to improve API response times and handle high load. I’m results-driven, pragmatic, and committed to shipping robust, maintainable systems that improve user engagement and operational performance.
