Chirag Gujarati iOS and React Native developer

Three apps, three hard problems

Real work that shipped to the App Store - a fitness platform that talks to gym hardware, a screen-time app that actually enforces focus, and a streaming catalogue rebuilt for speed.

Hardware that needed an app

Skandika - German fitness platform

Native iOS app that pairs over Bluetooth with ergometers, rowing machines and bikes - live metrics in, guided training programs out. Shipped in six languages with HealthKit sync.

Screen time, actually enforced

Lookupp

Built on Apple's ScreenTime API to lock distracting apps and pay users back in points for staying focused. Getting that framework to behave reliably was most of the work.

Redesign and rescue

Silver Stream

A 1,500-title catalogue of classic film and television. I redesigned the interface and fixed the performance problems that made a library that size stutter.

Services

Everything an app needs across its life - building it, proving it works, shipping it, and keeping it healthy afterwards.

App development

Native iOS in Swift and SwiftUI, or React Native when you need both platforms from one codebase.

  • New apps from first screen to App Store listing
  • Native iOS in Swift, SwiftUI and UIKit
  • React Native for iOS and Android together
  • Device features: Bluetooth, HealthKit, ScreenTime, notifications

QA and testing

Finding what breaks before your users do - on the devices and OS versions they actually own.

  • Manual test passes across real devices and iOS versions
  • Unit and UI test coverage where it earns its keep
  • TestFlight beta rounds with your own testers
  • Pre-submission checks against App Store review rules

Bug fixing and maintenance

Keeping a shipped app healthy - crashes triaged, regressions caught, dependencies current.

  • Crash triage from Crashlytics and Xcode Organizer
  • Fixes for the major iOS release every September
  • SDK and dependency upgrades before they break you
  • Small feature changes on an ongoing basis

Release and CI/CD

Automating the tedious half of shipping, so a release stops being an event you dread.

  • Xcode Cloud and CI pipelines set up end to end
  • Signing, certificates and provisioning handled
  • Automated builds to TestFlight on every merge
  • App Store submission, review and phased release

Performance and redesign

For apps that already work but feel slow, dated, or awkward to move around in.

  • Profiling with Instruments to find the real bottleneck
  • Smooth scrolling for large lists and media catalogues
  • Interface redesign and migration to SwiftUI
  • Objective-C to Swift migration without downtime

Backend and AI

The part behind the app - data, accounts, and AI features where they genuinely help.

  • Firebase and Supabase: auth, database and storage
  • Custom APIs in Python, deployed on AWS
  • Realtime sync and offline-first data
  • AI features and agent workflows inside the app

How I work

Four steps from first call to a live App Store listing - you always know what happens next.

01

Discovery call

Thirty minutes to understand the app you want and who opens it. I'll say honestly whether I'm the right fit.

02

Scope and estimate

A written plan: what ships in version one, what waits for later, how long it takes and what it costs.

03

Build in the open

TestFlight builds early and often, so you are using the real app on a real device long before launch day.

04

Ship and stay on

I handle submission, review and release - then stick around for crash reports and the next version.

Client projects

Apps built and shipped for clients - every one of these is live on a store today.

Highly Skilled iOS Developer! I had the pleasure of working with Chirag G on an iOS app project, and I couldn't be more satisfied with the results. From the beginning, he showcased exceptional expertise in Swift and iOS development, ensuring a smooth and efficient workflow. Chirag is not only technically skilled but also highly professional and proactive. He communicates clearly, meets deadlines, and goes the extra mile to improve the project with his valuable insights. His problem-solving skills and attention to detail truly set him apart. If you're looking for a top-notch iOS developer, I highly recommend Chirag G. I would love to collaborate with him again in the future!

Chirag has been fantastic to work with! He's extremely responsive, communicates clearly, works incredibly fast, and consistently delivers high-quality work at a very reasonable price. We've worked with him extensively on a major overhaul of our app's backend logic, numerous new features, UI refinements, bug fixes, and much more. What really sets Chirag apart is how much he goes above and beyond. He genuinely cares about the product, proactively identifies things we can improve, suggests new features, and even shares ideas for how we can grow and scale the app. He's extremely flexible, dependable, and always willing to help. On top of all that, he's just a genuinely great guy and a pleasure to work with. I couldn't recommend Chirag more highly!

About Me

An iOS and React Native developer from Ahmedabad, building for domestic and international clients since 2021.

I build mobile apps end to end - architecture, interface, device integrations and the App Store release itself. Five years in, across three product companies, most of that time has gone into native iOS with React Native alongside it when a client needs both platforms from one codebase.

The work I enjoy most is the part that's hard to fake: pairing with Bluetooth hardware, keeping data intact with no connection, bending Apple's ScreenTime and HealthKit frameworks into shape, and making apps fast again after they've grown heavy. Lately I've been folding AI agents into that mix.

How I work

  • Ship to the App Store, not to a demo - review, entitlements and release included.
  • Native where it matters, cross-platform where it pays. The choice follows the product.
  • Design for the offline case first. Connectivity is a feature, not an assumption.
  • Stay on after launch for the crash reports and the follow-up releases.
