Freelance in Guwahati & Assam

Freelance software developer in Guwahati

I'm Jishnu Mahanta, a freelance software developer in Guwahati. I build web apps in Next.js, Android and iOS apps, custom software and internal tools, and AI assistants that answer customers and book work. You deal with the person writing the code, we can meet in person around Guwahati or talk by video, and the code is yours.

Problems this solves

  • You need a website, app or internal tool built, and an agency's account manager, designer and developer chain is more than the job needs.
  • Your business runs on WhatsApp messages, spreadsheets and phone calls, and you want one system that keeps the orders, leads or bookings in order.
  • You have a website that looks fine but loads slowly, does not show up on Google, or cannot take a booking or an enquiry.
  • You tried a freelancer before and ended up with code you could not run, change or hand to someone else.

What I build

  • Websites and web apps in Next.js and TypeScript, fast on mobile and set up so Google can read them
  • Android apps in Kotlin and Jetpack Compose, and iOS apps in Swift and SwiftUI, that keep working with a patchy connection
  • Custom software and internal tools: dashboards, admin panels, order and inventory trackers, reports that used to take an afternoon
  • AI assistants for your site or WhatsApp-style enquiries: answering common questions, collecting details and passing real leads to you
  • Booking, enquiry and lead forms that land in a spreadsheet or CRM you already use
  • Hosting, domains, analytics and the handover, so the finished work does not depend on me

How it works

  1. 1Talk it through

    We meet in Guwahati or on a video call. You tell me what the business does and what is slowing it down, and I write down what we will build and what can wait.

  2. 2Agree the scope

    You get a written scope and a quote for that scope, with the price fixed before work starts, so you know what you are paying for.

  3. 3Build in the open

    The work lives in a GitHub repository in your name, with a staging link you can open on your own phone as it takes shape.

  4. 4Hand over

    I hand over the source, the accounts and a short runbook, and walk you or your team through them on a call.

Try it live

Try the lead-to-CRM demoA fictional agency's enquiry form that writes a clean lead row, scores it and drafts the reply, with each step shown.

Working with clients abroad

I work remotely with clients worldwide from Assam, India, and in person across Assam and Guwahati. Quotes are in USD and paid by Wise or international bank transfer. Code lives in your GitHub from day one, and you get a staging link to try at every step.

Questions

Yes. I live in Guwahati, so we can meet around the city for the first conversation and for reviews, and I also work by video call if that suits you better.
You talk to the person who builds the work, with no account manager in between, and small jobs are not stretched to fit an agency's process. For a very large team build, an agency may suit you better, and I will say so.
You do. The repository, the domain, the hosting and any developer accounts are in your name, and I hand over the full source when the work is done.
It depends on the scope, so I quote after a first conversation, with the price fixed for that scope before work starts. Bring what you already have, even rough notes, and I will tell you what it takes.
You can keep me on for fixes and changes, or hand the project to someone else, because the code is documented and in your name.

Tell me what you have in mind, and I'll tell you how I'd build it.
