сhallenge_Slow and unstable booking experience

"High re-render rates and heavy layout shift on the complex, dynamic hotel booking page"solution

"Redesigned the room selection funnel with optimal API data structures, custom memoization, and atomic state updates to handle heavy price calculations and interactive tariff options seamlessly"result

70% unnecessary re-renders
50% layout shifts during room selection
40% faster room selection flow
Conversion rate by 12%

I optimized a high-load booking funnel by redesigning component architecture, implementing advanced state management patterns, and improving API data handling. These changes reduced unnecessary rendering, stabilized dynamic UI updates, and delivered a faster and more reliable room selection experience.

problem_API architecture migration without service disruption

"Migrating core high-traffic flows from GraphQL back to REST API without breaking existing client runtime"solution

"Refactored data-fetching architectures, re-engineered TypeScript interfaces, and implemented robust mapping layers to transition legacy components to a streamlined REST response model"result

0% downtime during API migration
35% API response complexity
40% frontend maintenance effort
30% development velocity

I participated in the transition from GraphQL to REST by refactoring data-fetching logic, redesigning TypeScript contracts, and implementing reliable mapping layers between API responses and frontend components. These improvements reduced architectural complexity, increased maintainability, and helped the team deliver new features faster.

problem_Search performance bottlenecks on interactive maps

"Poor UI responsiveness and search bottlenecks when filtering massive hotel datasets on an interactive map"solution

"Optimized the search engine frontend using efficient debouncing,spatial filtering logic, and custom map rendering, significantly lowering input lag during heavy filter actions"result

80% input lag during search interactions
60% map rendering time
45% faster search experience
15% search-to-booking conversion
