About

As a Software Engineer at Walmart, I am a results-driven Software Engineer with a proven track record in designing and implementing scalable, high-performance systems. With expertise in Java, Python, Spring Boot, Kafka, RabbitMQ, Docker, and Redis, I excel in building modular architectures and optimizing backend operations for efficiency and reliability. My professional experience includes implementing RBAC-based access control systems, leveraging multithreading for parallelized database operations, and integrating advanced monitoring solutions with DataDog. I have successfully reduced response times by 50%, optimized computation time by 10%, and streamlined database operations through batching and pagination, ensuring seamless system performance. I have engineered impactful solutions like a real-time news aggregator using Kafka, a Redis-backed rate limiter, and an advanced search interface with autocomplete functionality. These projects showcase my ability to handle complex data processing, real-time updates, and frontend-backend integration. With a strong foundation in algorithms and problem-solving, recognized by top rankings in LeetCode contests, I am committed to pushing technical boundaries and delivering innovative solutions. I thrive on solving complex challenges, improving system performance, and leveraging cutting-edge technologies to drive impactful results.

Implemented an RBAC-based access control system, enforcing role-specific restrictions to ensure 100% of new users have appropriate roles for accessing critical RESTful APIs improving security compliance by 100%.
Developed an AOP-based interceptor for automated database row count threshold monitoring, integrated with Data-dog using Gauge Metrics. Leveraged Radar for automated alerts on threshold breaches, reducing manual monitoring by 90% and improving response times by 50%.
Implemented optimized batch-based database pagination to streamline user audit history access, reducing load times by 40%. Addressed database connection timeouts caused by long-running SQL queries.
Developed a Python script to fetch database records every 15 days via API and store them in AWS S3, optimizing SQL database memory usage.
Optimized computation time by approximately 10% for search, insert, and update operations in PostgreSQL using CompletableFuture, leveraging multithreading to parallelize database calls.
Developed a search interface with autocomplete, constructing tries from database-fetched data on application startup. Enabled real-time suggestions for queries over 3 characters, boosting user engagement by 50%.
Implemented a mechanism to publish new database inserts/updates to AWS SQS, enabling the reader service to consume messages via RESTful APIs and update its cache for real-time data synchronization.
Implemented an audit tracking system to capture historical entity values and user changes, ensuring data accuracy and traceability over six months via seamless frontend and backend integration.
