I am a Senior Software Developer with extensive experience in PHP, MySQL, Laravel, CodeIgniter, Codeception, Elasticsearch, Kafka, Redis, HTML, CSS, JavaScript, jQuery, and various other JavaScript libraries. I specialize in building robust, scalable web applications while maintaining clean, efficient code.

Throughout my freelance career, I contributed to numerous projects, taking on backend, frontend, and architectural optimization responsibilities. I worked on e-commerce platforms, corporate websites, CRM systems, and various other applications. My role involved designing scalable architectures, optimizing system performance, and developing full-stack solutions tailored to client needs. I leveraged a wide range of technologies to build efficient, high-quality software solutions.

My role involved improving system efficiency, ensuring seamless integrations, and maintaining high-quality, well-tested code.

At Beyn Technology, I played a key role in both backend and frontend development, focusing on API development and optimization, backend panel enhancements, and performance tuning for large-scale data processing. I developed and optimized cron jobs and supervisor-managed scripts to efficiently process terabytes of data.

When MySQL reached its limits, I integrated Elasticsearch into projects and designed the data architecture to ensure high-performance querying and reporting. I also enabled the generation of optimized reports from massive datasets.

On the frontend side, I contributed to algorithmic development for complex mathematical computations, ensuring accurate and efficient calculations for various use cases.

During my 6-month tenure at Allesgo, I developed and delivered over 30 e-commerce and corporate websites, handling both backend and frontend development.
