Key Achievements at Traya. Improved Dashboard Performance: Reduced KPI dashboard load time by 10x times, using optimized BFS traversal approach for rm lookup performance with application level optimizations and Redis caching ( 1hr TTL). Automated Attendance: Automated attendance for employees by designing a proxy request handler using Axios for KEKA CRM integration, incorporating retry mechanisms like Exponential Backoff with jitter—saving 2+ hours weekly. Microservice Optimization: Reduced load on a single microservice by 20% by architecting the entire Traya Quality Ops microservice, integrating ESLint, Prettier, MongoDB, PostgreSQL, Grafana ( Prometheus, Loki ), and Redis, RabbitMQ. Error Reduction: Automated multilingual coach assignments using cron jobs, decreasing manual errors by 25% and improving operational efficiency. Performance Optimization: Reduced production build bundle size by 250MB by replacing Bootstrap with Tailwind CSS and implementing purging techniques, enhancing cross-device performance. Data Rendering Dashboard: Built a multi-filter data rendering dashboard (SSOT) using Antd tables and Zustand for state management with pagination, improving data handling and reducing redundant API calls. Attendance Accuracy: Developed UI/UX for Auto Clock In/Clock Out feature, reducing manual attendance errors by 30% by comparing client local time with UTC time zones for timely notifications. Revamp: Led the migration of Traya’s codebase from a Node.js/Express/JavaScript stack to Next.js and TypeScript, improving code maintainability and scalability.Key Tech StackBackend: Node.js, Express.js, Nest.js, PostgreSQL, MongoDB, Redis, Axios, KafkaFrontend: React, React Query, Next.js, Tailwind CSSTools: Grafana, Bookshelf ORM, ESLint, Prettier, Loki, Cron Jobs
