Hi, I'm
Saurabh Dantani
Freelance Full Stack, Backend & Automation developer. Building production-grade web applications, backend microservices, real-time WebSocket platforms, and scrapers using React, Next.js, Node.js, NestJS, .NET Core, Python & AWS.
Saurabh Dantani is a freelance full-stack developer, backend engineer, and automation specialist based in Ahmedabad, India. He builds React, Next.js, Node.js, and NestJS products, plus .NET Core microservices, production scrapers (Playwright, Python), and real-time WebSocket platforms. He works remotely with teams across India, USA, UK, UAE, and worldwide.
A builder from Ahmedabad who ships for the world.
I'm Saurabh — 4+ Years of engineering at Ambit Global Solutions & Future Stack Solutions, collaborating with teams who need more than just a landing page.
I design the product architecture, write robust backend microservices, and build high-throughput data scrapers when the source is complex. That's how real-time IPO tracking systems, lead generation CRM platforms, and medical RCM engines got shipped to production.
Remote-first. India and worldwide. If it has to stay up, I treat it like production from day one.
Product & web
Next.js and React apps that feel finished — dashboards, SaaS platforms, and admin portals clients actually use every day.
Backend & APIs
NestJS, Node.js, and .NET Core microservices. Built with clean architecture, connection pooling, and resilient API contracts.
Web scraping
Playwright, Puppeteer & Python scrapers with proxy rotation, anti-detect handling, retries, and automated cron pipelines.
AI that ships
LLM integrations, automated data processors, and real-time WebSocket pipelines built to handle high throughput in production.
End-to-end engineering from concept to scale.
Clean architecture, real-time features, automated scraping pipelines, and production-grade performance.
Full Stack Web Development
I build fast, scalable, SEO-friendly web applications with React.js, Next.js, TypeScript, and Node.js. From enterprise dashboards to multi-tenant SaaS platforms — clean architecture and production-grade performance.
- ▸Next.js & React.js web apps
- ▸TypeScript strict type architecture
- ▸Modern UI with Tailwind CSS & Framer Motion
Backend Microservices & APIs
I engineer scalable RESTful APIs, high-throughput microservices, and secure databases using NestJS, Node.js, Express, and .NET Core with C#.
- ▸NestJS, Node.js & Express microservices
- ▸.NET Core & C# backend architecture
- ▸PostgreSQL, MongoDB, and MSSQL schemas
Web Scraping & Automation
I build Python backends, production web scrapers, and RPA bots — Playwright, Puppeteer, and Python data pipelines with proxy rotation, anti-detect configs, and retry-safe jobs.
- ▸Playwright, Puppeteer & Python scrapers
- ▸Lead extraction & market data pipelines
- ▸Automated scheduled cron workflows
Real-Time Systems & WebSockets
I develop low-latency live platforms such as real-time IPO tracking systems, live market feeds, and bi-directional notification engines powered by Socket.IO and WebSockets.
- ▸Low-latency WebSocket & Socket.IO streams
- ▸Real-time financial & market data processing
- ▸Live notification & trigger systems
CRM & Admin Dashboards
I create specialized CRM platforms, lead generation portals, and admin dashboards for business development and operations teams, complete with RBAC permission matrices.
- ▸Custom CRM & BD lead management
- ▸Role-based access control (RBAC)
- ▸High-performance analytics dashboards
Cloud Infrastructure & DevOps
I configure and maintain reliable cloud infrastructure on AWS — EC2 instances, RDS databases, S3 storage, Docker containerization, Nginx reverse proxies, and PM2 process management.
- ▸AWS (EC2, RDS, S3) architecture
- ▸Docker containerization & deployment
- ▸Nginx reverse proxy & SSL automation
Roles that compound — from scalable microservices to automation in production.
