Hi, I’m Rohit Gupta, a backend engineer with 9+ years of experience building, optimizing, and migrating production-grade server infrastructure for startups and enterprises. I specialize in developing websites (especially shopify and ecommerce) and scalable systems from scratch using Node.js, NestJS, TypeScript, PostgreSQL, Redis, BullMQ, AWS SQS, Kafka, and Cron scheduling. I’ve delivered custom websites (including Nuxt.js frontends), Shopify theme development, and full-text search integrations. I’m comfortable across the full DevOps stack - AWS (EC2, RDS, S3, SQS, Lambda), Railway.com, and self-hosted Linux environments. I have shipped multi-service backends with Docker, Nginx, and CI/CD pipelines, and I enjoy mentoring junior developers and leading end-to-end product engineering for client projects.…Hi, I’m Rohit Gupta, a backend engineer with 9+ years of experience building, optimizing, and migrating production-grade server infrastructure for startups and enterprises.
