For founders & product teams who need an app built — and launched

Ramandeep KaurFlutter, iOS & Android Developer for Startups

You bring the idea. I build the app — and get it live on the App Store and Play Store.

For 7+ years I have helped startups and businesses ship real mobile products — iPhone and Android apps people actually use. I build the features clients ask for most: payments, subscriptions, in-app chat, push notifications, maps & live tracking, and AI — then take your app all the way to the stores.

Let’s build your next app.

Let’s discuss your goals, technical requirements, and the best path to launch.

7+ years · 40+ live apps · Clients in USA, UK, Qatar, Brazil & more

You should not have to wonder if you hired the right person.

Clients come to me when the app matters too much for guesswork — when they want a lead who designs the architecture, writes the code, and owns the store launch. The result is calm delivery: clear updates, clean builds, and a product you are proud to put your name on.

  • Startups & founders

    MVP to v1 launch — clean scope, fast iteration, store-ready delivery.

  • Businesses going digital

    Customer apps, marketplaces, logistics, booking, and ops tools that must work every day.

  • Teams that need a lead

    Architecture, native bridges, AI features, and release management when your project gets serious.

Trusted across borders and industries.

You should not have to guess whether a developer can work with your market, your users, or your compliance needs. Here is the ground I have already covered.

Remote delivery with stakeholders in the USA, United Kingdom, Brazil, Qatar, France (Paris), Russia, India, and South Africa — different time zones, expectations, and product cultures, same standard of execution.

What I can build for you.

Not a résumé of tools — the capabilities that decide whether your app ships, scales, and feels premium.

  1. 01

    iOS + Android from one codebase

    Flutter apps that look native, move fast, and reach both stores without paying twice for the same product. Ideal when you need to launch with momentum.

  2. 02

    Native iOS when quality matters

    Swift & SwiftUI for the moments Flutter alone is not enough — polish, performance, and App Store confidence that investors and users notice.

  3. 03

    Maps, tracking & device hardware

    Live location, routing, BLE, and iBeacons for ride-hailing, logistics, field ops, and connected products — the hard features most freelancers avoid.

  4. 04

    AI inside your product

    OpenAI & Gemini features users actually feel — notes, summaries, voice, assistants — integrated cleanly into your app, not bolted on as a demo.

The features clients ask for most — already in my toolkit.

These are the premium building blocks behind almost every successful modern app. One development partner for Flutter, native iOS, Android, and AI-powered features.

  • Payment gateways

    Secure checkout with Stripe, Razorpay, Cashfree, and similar gateways — cards, wallets, and local payment methods your market expects.

  • Subscriptions & in-app purchases

    Recurring plans, trials, upgrades, and App Store / Play Store billing that pass review — so revenue starts when users tap Subscribe.

  • In-app chat & messaging

    Real-time chat for marketplaces, support, drivers, and teams — media sharing, read states, and conversation flows that feel instant.

  • Push notifications

    Orders, alerts, reminders, and re-engagement via FCM and APNs — timed and targeted so users come back without spam.

  • Maps, live tracking & routing

    Google Maps and Apple Maps for ride booking, delivery, logistics, and field apps — ETA, routes, and live location that stay accurate.

  • Auth, admin & AI features

    Login, roles, dashboards, and OpenAI / Gemini features — the backbone that turns a prototype into a product you can run and scale.

Apps I have already put in people’s hands.

Proof you are not hiring for theory. These products are live on the App Store and Play Store — the same finish line your project needs.

Construction marketplace

Ubuild

A multi-sided construction platform where homeowners, contractors, and vendors discover services, procure materials, and stay aligned — the kind of complex product that needs clear roles, messaging, and rock-solid releases.

What went into it

  • Flutter architecture for multi-role user journeys
  • Firebase auth, data, and push for daily engagement
  • Vendor / contractor messaging and media workflows
  • End-to-end App Store & Play Store publishing

Real estate marketplace

Flippbidd

A property marketplace where buyers and sellers list, negotiate, and talk in real time — built for trust, speed, and the messy reality of deal-making on mobile.

What went into it

  • Listing, offer, and deal flows that feel simple
  • Real-time chat and notification systems
  • Map-aware discovery for property search
  • Secure accounts for marketplace transactions

AI productivity app

Summarizex

An AI note-taker that turns voice and text into clear summaries — proof I can take cutting-edge AI APIs and ship them as a product people open every day.

What went into it

  • Flutter client with reliable local note storage
  • OpenAI / Gemini for smart summaries
  • Voice transcription wired into a clean UX
  • Store compliance for AI-generated content

Questions clients ask before we start.

Straight answers — so you know what working together actually looks like.

Will my app actually make it onto the App Store and Play Store?

Yes — store launch is part of how I work, not an afterthought. I handle privacy manifests, permission rationales, data safety forms, in-app purchases, and rejection fixes. Across 40+ shipped apps I plan compliance early (location, BLE, AI disclosures) so your release is not blocked in the final week.

Can you build advanced features Flutter alone cannot handle?

Yes. When your product needs hardware or OS-level power, I bridge Flutter to native Swift/Kotlin with Method Channels — BLE/iBeacons, Apple Maps routing, secure Keychain storage, background location — so you get one codebase without hitting a technical dead end.

Can you work with my team if we are in the US, UK, or Middle East?

Yes. I am based in Mohali, India (IST) and regularly overlap with US mornings, UK afternoons, and Middle East business hours. You get clear async updates in your tools plus discovery and sprint calls in your preferred window — so remote delivery feels predictable, not chaotic.

Work with someone who already knows the way.

Forty‑plus apps later, the process is steady: honest scope, careful craft, and releases that hold up in the real world. Clear communication, thoughtful engineering, and reliable delivery from kickoff to launch.

  • Decision settles fast

    You will know on the first call if we are the right fit. No pressure. No fog.

  • Delivery you can trust

    Clear milestones, store‑ready code, and communication that makes remote work feel simple.

  • Clients come back

    When people are happy with the product, they return for the next version — that is the real review.
