At Beventi, I developed and launched the core seller financial system for its creator and event-commerce platform, including onboarding, order management, refunds, and multi-currency payouts using Stripe Connect and PayPal.
I also built a Nuxt 3 analytics dashboard for seller revenue and customer engagement, and engineered a print-quote file workflow with direct S3 uploads.
At ServMask, I owned the backend of a Laravel 8 e-commerce platform and implemented payment processing across Stripe, PayPal, and Braintree. I cut API response times by 60% with query optimization and Redis caching, and modernized 15,000+ lines of legacy code while increasing PHPUnit test coverage from 25% to 65%.
Earlier, I developed CRM and integrations at Foundry, and worked on marketplace APIs, OAuth 2.0 authentication, and quote comparison at Cherehapa. I also developed e-commerce and checkout features at E96.ru and delivered 15+ client websites through Clever Projects.
