IndiaWhat I'm looking for
At Pearlsoft Technologies, I designed, built, and maintained PHP/Laravel REST APIs for AGL Energy’s telecom CRM platform, supporting customer, billing, inventory, and order-management workflows. I improved billing API response times by approximately 35% through MySQL indexing, execution-plan analysis, and query optimization.
I developed RabbitMQ-based asynchronous processing with retry and reconciliation logic, integrated third-party billing, payment, and telecom APIs, and investigated production incidents. I also introduced structured logging with Monolog and wrote PHPUnit tests for releases delivered through GitLab CI/CD pipelines.
As a freelance PHP Developer / Consultant, I delivered custom applications, REST APIs, and WooCommerce stores for international clients. My work included WordPress websites, payment-gateway integrations, and vtiger CRM customizations. I’m AWS Certified Solutions Architect – Associate and am open to on-site, hybrid, or remote roles.
