Worked as part of an outsourcing team developing platforms for clients.

- Designed and implemented a modular architecture using PHP 8.5 and Laravel, reducing estimated

development effort for new products by 10-15%, including a reduction from 400 to 350-370 hours for

one project.

- Built a targeting module using Laravel and PostgreSQL that creates user profiles from user data and

uses them to select personalized promotions and banners, increasing CTR from 0.4% to 1.3%.

- Implemented a player-to-court allocation mechanism based on the Berger algorithm using Laravel

for the Americano Classic mode in a padel app. Approximately 23% of the app's monthly active users

used this mode.

- Resolved performance issues across client platforms by analyzing bottlenecks and optimizing

application performance. Improved the homepage LCP to 1.7 seconds in one product.

- Integrated and optimized data exchange with third-party services, including CRM systems, 1C, and

notification services.

- Automated application testing, builds, and deployments using GitLab CI.

- Delivered major features for client projects, coordinating with teams responsible for related services.
