Kamran Momayez

Architected and contributed to a large-scale microservice platform spanning project management, workflow automation, sales, and accounting modules using Laravel (PHP 8.4), enabling independent service evolution and horizontal scalability across engineering teams. Engineered high-performance RESTful APIs and internal microservice communication using gRPC and Protocol Buffers, along side Redis caching strategies. Optimized relational database design across MySQL and PostgreSQL, reducing API response times from 15 seconds to under 1 second. Ensured production stability through centralized logging (MongoDB), Grafana dashboards, and 90%+ unit and feature test coverage.

Engineered high-performance RESTful APIs and internal microservice communication using gRPC and Protocol Buffers; implemented Redis caching strategies and optimized relational database design across MySQL and PostgreSQL, reducing API response times from 15 seconds to under 1 second. Achieved 95% test coverage with PHPUnit (unit, functional, integration) and Behat; enforced coding standards via PHPStan and GrumPHP. Configured and maintained CI/CD pipelines (Bitbucket Pipelines) for automated testing and zero-downtime deployments.

Designed and built REST API with microservice architecture using Laravel (PHP 8.4), MySQL, Redis, Docker, Nginx, and related tooling. Led full-stack refactoring and migration of a legacy Laravel 5.3 application to Laravel 9; applied SOLID principles, OOP design patterns, and Docker containerization. Grew automated test coverage to over 90%, eliminated 90% of post-release defects; managed GitLab CI/CD pipelines for automated builds, testing, and zero-downtime deployments. Led code reviews and architecture sessions, mentoring backend engineers on design patterns, OOP, and clean code.
