Mar 2022 – Dec 2022
Frontend Engineer • Bangalore, India
  • Optimized e-commerce job search interfaces for scale-out platforms (Meesho, Gojek), leveraging selective bundle compilation and component memoization to yield an 8% uplift in runtime page performance.
  • Integrated real-time virtual conferencing infrastructure utilizing the Zoom Core SDK for Vidhyawin, boosting aggregate digital user engagement by 16%.
  • Refactored electronic health record (EHR) entry modules for hospital operations, introducing client-side schema validation rules that improved production database record accuracy by 12%.

Featured Engineering Projects

High-concurrency systems and low-level architectural implementations.

Distributed Systems

E-Commerce Product Microservices Engine

Architected a microservices-based e-commerce platform separating architectural responsibilities across Product Catalog, Payment Gateways (Razorpay), Order Processing, and asynchronous notification workers via Apache Kafka. Reduced API response times from ~500ms down to ~50ms through Redis read-through caching and optimized data-access patterns.

Spring Boot Spring Cloud Apache Kafka Redis Elasticsearch MySQL
Low-Level System Design

Concurrent Console TicTacToe Engine

Designed an extensible, low-level object-oriented board engine using clean SOLID guidelines, applying structural and behavioral patterns (Strategy, Observer, Singleton) to yield full decoupling. Structured thread-safe concurrency models utilizing atomic states and synchronized primitives to handle multi-user input loops without race conditions.

Java Multithreading SOLID Design Design Patterns

Education & Problem Solving Foundations

Extensive focus on deep algorithmic problem-solving skills, data structures (Graphs, Trees, HashMaps, Dynamic Programming), and System Design.
