Who Am I?

About Me

A passionate backend developer with a deep interest in programming, database design, and building effective software architectures. With years of hands-on experience, I have worked extensively on ERP solutions, financial systems, SaaS applications, eCommerce platforms, and custom plugins—delivering scalable and efficient software tailored to client needs.

My technical expertise spans across PHP (Laravel, CodeIgniter, Zend Framework), WordPress development (including custom plugins), and database management with MySQL, PostgreSQL, MS SQL Server, and MongoDB. I specialize in building and integrating RESTful APIs, caching with Redis, and ensuring high-quality software through PHPUnit testing. My proficiency in Agile methodologies, Git, and Jira allows me to collaborate effectively in fast-paced development environments.

Beyond development, I have contributed to diverse projects, including self-assessment platforms, government initiatives, and core banking integrations, ensuring smooth connectivity with financial systems. Additionally, I bring strong expertise in Linux Server Administration (RedHat 8 Certified) and cloud platforms like AWS and DigitalOcean, optimizing deployments and server performance.

I thrive on solving complex challenges and take pride in creating robust, scalable, and maintainable systems. When I’m not coding, I enjoy exploring new technologies, optimizing workflows, and contributing to projects that push the boundaries of innovation.
