Chirag Sinha — Software Engineer

Passionate Software Engineer with expertise in backend development, distributed systems, and high-performance architecture. I specialize in scalability, microservices, event-driven architectures, and optimizing large-scale systems to deliver low-latency, high-throughput applications. At Zomato, I engineered a cross-platform Single Sign-On (SSO), enhancing security while reducing unauthorized access by 80%. I built the express ordering model, cutting delivery time to under 30 minutes, and optimized a high-traffic historical API, slashing latency by 98% using Kafka-driven DynamoDB pre-calculation and Redis caching. Additionally, I replaced a high-resource cron job with an event-driven hybrid model, reducing execution time from 2-3 minutes to just 300ms. Previously at Zeotap, I designed a high-efficiency polling service, reducing system load by 30%, and optimized microservices, cutting CPU & memory usage by 15%. At Scaler, I developed Admin Dashboard features, improving page load speed from 65% to 92%. Tech Stack: C++, Go, JavaScript, Node.js, Kafka, RabbitMQ, Redis, DynamoDB, PostgreSQL, MySQL, AWS, Microservices, System Design, Event-Driven Architectures, Caching Strategies, Real-Time Data Processing.

SDE-1

Jul 2023 – Jul 2025 · 2 yrs · Gurugram, Haryana, India

Implemented cross-platform SSO, enhancing security and reducing unauthorized access by 80%, improving login efficiency and reducing authentication failures.
Built the express ordering model, reducing delivery time to under 30 minutes by centralizing order management and syncing only relevant data via an event-driven approach, increasing orders by 15%.
Developed an automated ticketing system to eliminate item discrepancies in inter-warehouse deliveries, improving order fulfillment accuracy and boosting product reorders by 15%.
Optimized a high-traffic historical API, reducing latency by 98% by pre-calculating data in DynamoDB via Kafka-driven events and implementing Redis caching.
Accelerated API performance, reducing response times from 200-300ms to 10-20ms and long-running API calls from 1-2 seconds to 200ms via caching and query optimizations.
Replaced a high-resource cron job with a hybrid push-based model, reducing execution time from 2-3 mins to 300ms and eliminating redundant S3 calls by validating file headers before event-driven PDF merging.
