Here are some of my highlighted open-source contributions:

1. talent_form
   User profile/skills collection form with client-side validation, dynamic fields, and seamless API submission.

2. network_service
   Robust, reusable network layer for Flutter apps — handles API calls, error management, retries, and interceptors.

3. design_system
   Lightweight Flutter package providing consistent themes (light/dark mode), reusable widgets, and design tokens.

4. Card-Input-Field---Flutter
   Modular and customizable credit/debit card input field with formatting, validation, and secure UI.

(Pro tip: Pinning a BLE-related project next would perfectly showcase your full skill set for IoT/remote roles!)

I'm excited to work on challenging mobile projects — especially cross-platform development, BLE connectivity, secure/offline apps, or remote freelance gigs.
