Project history
Led a 5-member team to build a SaaS product using MERN stack, reducing latency by 40% through code optimization and caching. Optimized data validation workflows, refactored MongoDB aggregation pipelines, migrated from Angular to React, implemented CI/CD pipelines, designed OAuth 2.0/JWT auth flow, and integrated Stripe API for payment processing.
Developed a real-time chat application using Socket.io and Node.js. Redesigned navigation menu using React + Framer Motion, redesigned sorting algorithm for financial analytics, created reusable React component library, architected cloud-native migration to AWS, deployed scalable cloud infrastructure, and built Node.js chatbot with NLP.
