At DotWhite, I design and maintain PHP, Laravel, and Lumen microservices and web applications. I work on complex backend workflows, including Guzzle-based service integrations and S3 file handling for large PDF documents.

I use ChatGPT and Claude to support implementation, debugging, and refactoring, and I'm exploring agentic development workflows. I also maintain legacy Ext JS components and contribute OpenAPI documentation and PHPUnit tests.

At P4B, I designed, built, and optimized high-throughput microservices, and refactored legacy PHP applications to improve query performance, database indexing, and maintainability. I also standardized API documentation with Swagger and OpenAPI.

At Russmedia Tech, I led a team of five developers building job portals with Symfony, while serving as Technical Team Lead and Scrum Master. I worked on search optimization using composite indexes and EXPLAIN, and integrated Actonomy and Solr to improve job-matching relevance and search performance.
