Currently, I am working as a Backend Developer on the commerce side of a project for Muse Group. My primary focus is helping the company achieve its revenue goals by driving improvements in ARPU (Average Revenue Per User) and ARPPU (Average Revenue Per Paying User) metrics with every change I implement. Every feature and update I contribute to is driven by a data-driven approach, ensuring we consistently optimize for growth and profitability.

I actively participate in all internal processes, collaborating with cross-functional teams to drive development forward. I also contribute to fostering a strong corporate development culture by promoting a learning environment where teammates can grow efficiently. This includes performing thorough code reviews, refactoring outdated components and subsystems, and helping shape the long-term architecture vision for the project.

In addition, I assist the support team by streamlining decision-making processes through the development of automation systems that help manage and monitor paid products, ensuring smoother operations and reducing manual effort.

As a Team Lead, I took on a leadership role, overseeing a team of developers working on the Customer Support project. I was responsible for guiding the team’s development efforts, ensuring that tasks were aligned with the project’s objectives, and facilitating collaboration between different teams. I helped set priorities, track progress, and provided technical mentorship to junior and mid-level developers.

I also played a key role in architectural decisions, ensuring the systems we built were scalable, maintainable, and well-integrated with other parts of the company. I focused on fostering a positive team culture by encouraging best practices in code quality, performing regular code reviews, and ensuring the adoption of efficient workflows. Additionally, I worked closely with other departments to ensure that our solutions addressed both business and technical needs effectively.

At Skyeng, I worked as a Full-Stack Developer, developing the internal Customer Support project. The goal of the project was to create a system that enhanced the efficiency of various teams when interacting with users. I worked with Symfony 3-6 (upgrading as needed) and Angular 7-11 to build and maintain scalable solutions. I played a key role in integrating multiple systems across the company, ensuring smooth data flow and improving workflows. The result was a system that helped teams save valuable time and improve user support quality.

At AdSolution, a CPA marketing company, I worked on a side project developing an ad board platform similar to Facebook Marketplace using Yii2. This platform operated across multiple countries, requiring localization, multi-currency support, and region-specific features. I implemented advanced search and filtering, automated content moderation, and optimized database performance to handle high traffic and ensure scalability. Additionally, I integrated third-party advertising networks and automated reporting systems to enhance the platform’s efficiency. 

I also mentored several colleagues, teaching them programming and software architecture, and helping them develop their technical skills.

At SMMbro, I developed and optimized sales funnel automation for both B2B and B2C businesses. I worked on backend systems using PHP (Yii 2) and frontend development with jQuery. I improved API performance by implementing caching strategies and enhancing project architecture. I automated deployments with Docker and GitLab CI, reducing deployment times. I also integrated third-party marketing tools like Facebook Ads API and Google Analytics to enhance tracking and automation. Additionally, I improved testing processes to ensure system stability.
