I’m a frontend developer with 3 years of experience building and maintaining production web applications. I’ve worked on customer-facing features in both banking and CRM contexts, focusing on reliability, usability, and measurable performance improvements.

At GIZMO Studio, I developed and maintained the “Inbank” banking application using React and TypeScript. I migrated the application from SDK 34 to SDK 35 to meet Play Market requirements, implemented a trusted devices feature to speed up secure logins, and moved form validation logic to the backend using react-hook-form to improve reliability and reduce duplication. I also refactored key forms and UX flows with react-query and react-hook-form, and built a loyalty program module using a REST API and React Context API for personalized offers.

Previously, at Productlab, I supported a CRM system with React and Ant Design. I built a “Counterparties” module that reduced data processing time by 15% and improved information accuracy, optimized load performance with React.lazy and dynamic imports (10–12% faster), and maintained AmoCRM widgets by fixing critical integration issues and improving the UI for more intuitive navigation.
