I'm 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 and scalable web applications while using clean and efficient code.

Throughout my freelance career, I've contributed to numerous projects and assumed responsibility for back-end, front-end, and architectural optimization. I've worked on e-commerce platforms, corporate websites, CRM systems, and a variety of other applications. My role included designing scalable architectures, optimizing system performance, and developing full-stack solutions tailored to client needs. I've leveraged a wide range of technologies to create efficient, high-quality software solutions.

During my six-month tenure at Magellan, I worked with technologies such as PHP, Laravel, MySQL, Redis, JavaScript, HTML, CSS, and React. I played an active role in both back-end and front-end development, focusing on performance and scalability. I gained valuable experience in database optimization, API integrations, and developing modern web applications.

During my one-year tenure at Jotform, I worked on the Enterprise team, focusing on API development, backend services, and API testing. I contributed to SQL and code optimizations to improve performance and scalability. My role included improving system efficiency, ensuring seamless integrations, and developing high-quality, well-tested code.

At Beyn Technology, I played a key role in both back-end and front-end development, focusing on API development and optimization, back-end dashboard improvements, and performance tuning for large-scale data processing. I developed and optimized cron jobs and administrator-managed scripts to efficiently process terabytes of data.

When MySQL reached its limits, I integrated Elasticsearch into projects and designed the data architecture to provide high-performance querying and reporting, as well as generating optimized reports from large datasets.

On the front-end side, I contributed to algorithmic development for complex mathematical calculations, ensuring accurate and efficient calculations for a variety of use cases.

During my six-month tenure at Allesgo, I developed and delivered over 30 e-commerce and corporate websites, managing both back-end and front-end development. I implemented scalable and efficient solutions to ensure high performance and a seamless user experience. My responsibilities included database design, API development, UI/UX improvements, and optimizing website performance for better loading times and responsiveness.

I worked as a senior back-end PHP developer at Brilliant Bridge. We developed e-commerce and admin panels for their websites. We used technologies like PHP, Codeigniter, MySQL, and JavaScript.
