Demo First. Pay After. Zero Risk.
The MERN stack — MongoDB, Express, React, and Node.js — is the most popular way to build modern web products: one language (JavaScript) across the entire application, huge talent ecosystems, and rapid iteration. MynTech Software builds MERN applications for startups and businesses across the US, Europe, and India.
We put our engineering where our mouth is: your MERN application's working demo is deployed to a live URL for you to test before we send any invoice. Fast stack, fair terms.
Our promise is simple: we build your working demo first (for smaller projects, often the complete application). You test it, your team tests it, and only when you are satisfied do we talk about payment. No deposits. No risk. Just working software.

React single-page applications and admin dashboards with real-time data and clean UX.
Scalable Node.js and Express backends with documented APIs your mobile apps can share.
Chat, notifications, collaborative tools, and live feeds using WebSockets and Socket.io.
Server-side rendering with Next.js when your product needs to rank on Google, not just run in a browser.
MongoDB indexing, query optimization, caching, and load handling for growing user bases.
We understand your goals, users, and must-have features. NDA signed first if you prefer.
A clear scope, timeline, and fixed price — no hourly meters, no surprise invoices.
Your working application demo, built at our cost and delivered for you to test on a live URL or your own device.
Only when the demo meets the agreed spec does the first payment happen. You risk nothing.
We complete, polish, and launch the product — then support it with monitoring, fixes, and new features.
Almost any modern web product: SaaS platforms, marketplaces, social apps, dashboards, booking systems, and internal tools. If your product needs strong Google rankings, we add Next.js server-side rendering on top of the same stack.
MVPs typically run $3,000–$8,000; full products $10,000–$40,000. Dedicated MERN developers are available from about $2,200/month. Fixed quotes always, payment only after the working demo.
You get a coordinated team — developer, designer, QA, and project manager — with 15+ years of enterprise experience and production apps running 24/7, at rates comparable to a single Western freelancer. And unlike freelance platforms, you pay nothing before seeing your demo.
Yes. Monthly maintenance plans cover monitoring, bug fixes, security updates, and feature development, with response-time SLAs that respect your US or European business hours.
Tell us what you want to build. We will reply within 24 hours with a plan and a fixed quote — and then build your free demo. You pay only when you love what you see.
