What I do

Services that take your idea from concept to launch

Mobile App Development

Complete apps for iPhone & Android — login, payments, notifications, offline support and more.

Websites & E-Commerce

Business websites and online stores with carts, Razorpay/UPI payments and order tracking — ready to sell from day one.

AI Chatbots & Assistants

ChatGPT/Claude-powered assistants trained on your business — answering customers, taking bookings and capturing leads 24×7 on your site or WhatsApp.

MVP for Startups

Have an idea? I'll build a launch-ready first version fast, so you can validate it with real users and investors.

Backend, APIs & Integrations

Secure REST APIs, databases and admin panels — plus integrations like Razorpay, Google Maps, Firebase and WhatsApp.

App Rescue & Upgrades

Existing app or site that's slow, buggy or outdated? I fix, modernise and add new features to projects built by others.

How we'll work

A simple, transparent process

1

Discover

Free call to understand your idea, goals and budget. You get a clear plan & fixed quote.

2

Design

Screens and flows agreed before any code — so there are no surprises later.

3

Build

Weekly progress updates with working demos. You see the app grow, not just promises.

4

Launch

I handle Play Store & App Store publishing, and stay available for support after launch.

For agencies & studios

Your white-label development partner

Run a digital marketing, branding or design agency? I build the apps and web platforms your clients ask for — delivered under your brand, so you keep the client relationship and expand your service catalog without hiring developers.

100% White-Label & NDA-Friendly

Your brand on everything. I stay invisible to your client, sign an NDA upfront, and never contact your clients directly.

Figma to Flutter, Pixel-Perfect

Hand me your designer's Figma files and get back a working iOS + Android app or web app that matches them exactly.

Fixed Milestones, Fixed Price

Written quote before we start, milestone-based billing, weekly demo updates you can forward straight to your client.

About me

Hi, I'm Pavan 👋

I'm a senior software engineer from Pune, India, currently building the ProfitBooks mobile app used by businesses every day. Alongside my job I take on select freelance projects — which means your app is built with the same production-grade standards as a funded product, not hobby code.

I hold a BE in Computer Engineering (9.04 GPA) and build both the app your customers see and the backend that powers it — so I can deliver your entire product end-to-end, not just one piece of it.

My commitments to you

Five promises on every project

Fixed Written Quote First

You get the full price in writing before any work starts. The number I quote is the number you pay — no hourly meters, no surprise add-ons.

Pay Per Milestone

Never pay everything upfront. The project is split into milestones — you pay for each one only after you've seen it working.

Weekly Demo Updates

Every week you get a working demo of progress — you watch your app grow instead of waiting in the dark for a "big reveal".

You Own Everything

Source code, app store accounts, domain, database — all registered in your name from day one. Fire me anytime and lose nothing.

30-Day Bug-Fix Window

Anything broken within 30 days of launch, I fix free. After that, affordable maintenance plans keep your app healthy.

Same-Day Replies

WhatsApp me and hear back the same day, in English, Hindi or Marathi. No account managers, no ticket queues — you talk to the person building your product.

Questions

Frequently asked questions

How much does an app cost?

It depends on the features you need — after a free discovery call you get a fixed written quote, and that number is what you pay. No hourly surprises, and no agency overhead inflating the price.

How long does it take to build an app?

A focused MVP typically takes 4–8 weeks. Larger apps take longer — you'll get a realistic timeline upfront and weekly demo updates throughout.

Will my app work on both iPhone and Android?

Yes — I build one app that runs on both iPhone and Android, which roughly halves the cost and time compared to building two separate apps.

Do you build websites too, or only mobile apps?

Both. I build business websites, landing pages and full web apps — and if you need an app + website combo, the same app can even cover mobile and web together.

Can you add AI to my app or website?

Yes — I build AI chatbots and assistants powered by ChatGPT/Claude, trained on your business data: answering customer questions, taking bookings and capturing leads 24×7 on your website or WhatsApp. Try the NeoBot demo above to see one in action.

Can you add payments like Razorpay or UPI to my app?

Yes — payment integration is one of my core services. Try the ShopEase demo above to see a full Razorpay checkout flow in action.

Do you also build the backend / admin panel?

Yes — I build the full stack: the app, the server APIs, the database and an admin panel to manage your data.

Who owns the code and accounts?

You do — completely. Source code, Play Store & App Store accounts, domain and database are all set up in your name from day one. If we ever part ways, everything stays with you.

How do payments work?

Milestone-based: the project is split into stages with a price for each, and you pay for a stage only after seeing it working. You never pay 100% upfront.

Do you work with agencies on a white-label basis?

Yes — a big part of my work is white-label development for digital marketing, branding and design agencies. Everything ships under your brand, I sign an NDA, and I never contact your clients. See the For Agencies section above.

What happens after launch?

I offer post-launch support and maintenance plans, so bug fixes, OS updates and new features are covered.
