## Hey 👋, I'm [Subrata!]() 

### React Native Architect • Open Source Maintainer • Platform Engineer

![Subrata Das](https://github.com/subraatakumar/subraatakumar/blob/main/images/Subrata%20Das.png)

I design and build **scalable mobile platforms**, not just apps.

My work spans **React Native architecture**, **native Android/iOS integration**, **JSI & C++**, and **developer tooling**.

📍 Bengaluru, India 🇮🇳

🎓 Engineer by profession, **teacher by heart** ❤️

🧠 Passionate about **clean architecture, memory safety, and long-term maintainability**

## 🧠 What I Do (At an Architectural Level)

* Design **production-grade React Native architectures**

* Build **reusable platforms, CLIs, and design systems**

* Bridge **Java/Kotlin ↔ React Native ↔ JSI/C++**

* Solve **native performance & memory safety issues**

* Mentor engineers and students into **industry-ready developers**

## 🔥 Open Source Impact

### 🧩 React Native Skia (Shopify)

**Core Contributor**

* Fixed a **native C++ dangling pointer bug** in the Skia JSI layer

* Root cause: temporary UTF-8 string lifetime misuse triggering

  `-Wdangling-assignment-gsl` and breaking Android builds

* Solution: preserved backing string storage before `c_str()` usage

* Result: **Android native builds stabilized**, no API or behavior change

* PR reviewed and approved by core maintainer **@wcandillon**

### 🎨 @tcbs/react-native-mazic-ui

**Design System & UI Foundation**

* Reusable, theme-driven UI components for React Native

* Built with **scalability, consistency, and performance** in mind

* Used as a base UI layer for multiple apps and products

## 🎯 Real-World Engineering Challenges I’ve Solved

1. **Reverse-engineering an outdated Android SDK**

   Adapted an unmaintained POS Android SDK for React Native by

   studying native documentation and extending the NPM package.

2. **Reliable emulator detection without third-party libraries**

   Implemented a custom Android native solution (Java) and bridged it

   into React Native for startup-grade security requirements.

3. **Subscription-free reverse geocoding**

   Combined iOS free APIs with Android native `android.location.Geocoder`

   via React Native bridges to achieve accuracy without recurring costs.

## 🧑‍🏫 Beyond Code

* Mentor aspiring developers (free & open learning)

* Write blogs and teach **React Native from fundamentals to architecture**

* Believe in **giving back through open source**

When I’m not building platforms, I’m watching sci-fi movies 🚀 or writing.
