I build the web systems that businesses actually run on. An ERP that replaced a manufacturing company's spreadsheets. A Teams-style app used by 50+ concurrent users in real time. A high-conversion D2C e-commerce platform with instant checkout.
I build the web systems that businesses actually run on across the whole MERN stack — replacing spreadsheets with an all-in-one ERP, scaling real-time team collaboration for 50+ concurrent users, and tuning database queries down to 400ms.
invoice creation time in the ERP (was 15 min)
API response time after query optimization
database calls per request after removing N+1 queries
concurrent users active in real-time
Core technologies and production capabilities across client, server, and data.
React, Next.js, Redux Toolkit, Ant Design, Tailwind, dashboards and workflow screens. Built manufacturing ERP interfaces and the work platform used by 50+ concurrent users.
REST APIs, JWT auth, role-based access with 12 permission levels, around 90 protected routes in the ERP, and API response time cut from 2.3s to 400ms.
MongoDB schema design, aggregation pipelines, N+1 query fixes (15 to 2 database calls per request), and query tuning. Learning PostgreSQL.
Socket.IO with Redis, presence, delivery receipts, push notifications, and BullMQ event queues that replaced client polling, cutting server polling overhead by 90%.
AWS EC2 and S3, Nginx reverse proxy, SSL, PM2 process management, scheduled jobs, and GitHub Actions CI pipelines.
GST-compliant invoice and PO PDFs, email and WhatsApp automation, file uploads to S3.
Unit tests and automated test scenarios covering key user flows.
Production TypeScript, modern JavaScript (ES6+), and Java Spring Boot services.
Semantic HTML, structured data, Google Search Console indexing, and keyboard accessibility.
Sales, purchasing, stock, billing and HR in one system, replacing spreadsheets. Invoice creation dropped from 15 min to 2 min.
Built real-time chat, meetings, tasks and attendance. Socket.IO + Redis pub/sub delivers messages under 100ms, while BullMQ event queues cut server polling overhead by 90%.
D2C e-commerce platform built with Next.js, React 19, TypeScript, and Tailwind CSS. Features an interactive 10-flavor product showcase, pan-India pincode delivery estimation, dynamic cart, and instant UPI checkout.
Open for full-time engineering roles, production web applications, and contract development.
