Himanshu Choudhary / Flutter developer
Hey, I’m Himanshu, a Flutter developer based in Panchkula, India, turning everyday ideas into thoughtfully built Android & iOS apps. Welcome to my little corner of the internet.
Chapter 01 / The quest log
Different problems. Different people.
The same care for how it all works.
For the working day
Business travel, with the moving parts in one place. A B2B app for corporate cab operations and booking workflows.
My contributionDeveloped corporate mobility interfaces, booking workflows, maps, and service integrations in Flutter and Dart, using Riverpod for state management.
Read the Fomo engineering story
For the way there
From finding a ride to making a booking. A consumer cab app built around a clear, straightforward rider journey.
My contributionDeveloped consumer cab-booking interfaces and map-based rider workflows in Flutter and Dart, using Provider for state management.
Read the Fomo engineering storyField notes / Fomo Corp & Fomo Cabs
Two mobility products, with different booking journeys and the same need for dependable location and app state.
The engineering challenge
A booking screen, an animated car, background location updates, and cached data are parts of one experience. My work covered these moving parts alongside crash fixes and service integrations.
Architecture in context
Fomo Corp uses Riverpod; Fomo Cabs uses Provider. Both use Flutter and Dart for their cross-platform interfaces, with maps and booking workflows connected to application services.
Implemented car animation on the map as part of the ride experience.
Worked on background tracking so the location experience extended beyond the active app screen.
Handled offline caching and data-loss issues, alongside debugging work to reduce crashes.
What shipped
Two released mobility apps, with work spanning booking, map animation, background tracking, offline data handling, and crash reduction.
Engineering takeaway
For a mobility app, the work extends beyond the visible screen: location continuity, local data, and stability all shape the ride experience.
Food, health, commerce, and a few things in between.
Intercity food delivery with ordering, map, and payment workflows. Built with Flutter, GetX, Razorpay, and Google Maps.
A shopping platform for architects and interior designers, built with Flutter and Provider, with Razorpay payments and Google Maps integration.
Health Monitor Application connecting IoT devices through Bluetooth, built with Flutter and Riverpod.
Fresh fish, chicken, and mutton delivery across Kolkata and Howrah. Built with Flutter and Provider, with Razorpay payments and Google Maps integration.
An agricultural information app supporting cucumber farming practices, built with Flutter, GetX, and localization for accessible regional content.
A Flutter news and publishing app using WebView to present insights and guidance for small and medium businesses.
Chapter 02 / Character profile
I like making complex things feel simple on a small screen.
Over the past 3+ years, I’ve worked on mobility, food delivery, commerce, and health apps. My work covers the interface and everything it depends on: state management, APIs, maps, payments, and the journey to the app stores.
I care about code that the next developer can understand, and apps that people can use without thinking about the code at all.
Tools of the trade
My skill tree
The parts of app development I work on, from the first screen to a store release.
Flutter and Dart, with MVVM and state management suited to the app. Riverpod, Provider, and GetX are all part of my toolkit.
Architecture / State managementBooking flows, maps, payments, and APIs. I work with Firebase, Supabase, and local caching to connect the interface to the data behind it.
Integrations / Offline storageResponsive interfaces across Android and iOS, maintenance of existing codebases, and publishing to Google Play and the App Store.
Cross-platform / App publishingBehind the build / AI in my workflow
Codex Claude
I use Codex and Claude throughout my projects, from the first implementation plan to debugging and code review. I bring the context, constraints, and engineering judgment.
Plan features, compare architecture choices, and explore UI directions before turning an idea into focused implementation steps.
Give the tools project context, work in focused changes, and refine generated code to fit the app’s architecture and conventions.
Investigate bugs, review diffs, and challenge edge cases. Check suggestions against the actual code, then test the behavior.
My approach: AI assists. I make the decisions, review the code, and verify the result.
Chapter 03 / The origin story
