At Avito, I worked on Avito Delivery and E-commerce, including cart, checkout, pickup-point integration, returns, and tracking. I built a multi-seller purchase flow with independent delivery configuration and separate parcel tracking, and helped streamline checkout to reduce drop-off during payment and abandoned carts.
I also developed a test-state generator that cut manual regression preparation from several hours to a few minutes. I unified tracking across courier services and added cart pre-validation to block unavailable items before payment.
At Alfa-Bank (Russia), I worked on Alfa-Business, implementing real-time validation for international-payment forms and a bulk payment-signing interface. I set up UI test network mocking with MSW and React Testing Library, bringing key business-logic coverage to 80%.
