Flutter Developer with 1.5+ years of experience building Android business applications using Flutter and Dart. Hands-on experience translating workflows into responsive screens, integrating REST APIs, handling loading/success/error states, implementing navigation and validation, managing local data, debugging defects, and preparing release APKs. Comfortable owning features while following an established architecture and collaborating with backend and product stakeholders.

Mobile App Developer at TeckZy Research Analytics IT Solutions Pvt. Ltd. (2025-03 – Present)

• Owned Flutter development of an internal field-inspection application, delivering 10-15 screens/modules across login, dashboard, inspection queues, dynamic forms, client information, notifications, attendance, and activity reporting.
• Converted backend-defined inspection formats into reusable Flutter screens that dynamically rendered input fields and checkpoints, including remarks and Tick/Fail/NA states.
• Integrated REST APIs and JSON models for inspection retrieval, status updates, submission, resubmission, and client information, with loading, success, empty, timeout, and failure-state handling.
• Implemented named navigation, required-field validation, per-checkpoint state isolation, disabled-submit controls, and request locking to prevent incomplete or duplicate submissions.
• Managed on-device values with GetStorage and built REST-polling notification and assignment badges that remembered previously seen counts for each authenticated inspector.
• Diagnosed stale status defects through console logging and endpoint analysis; refreshed the list API and GetX observable state after successful updates so changes appeared without manual page refresh.
• Worked with an existing backend and product workflow, maintained reusable GetX controllers/widgets, and prepared release APKs for device-level testing and private company evaluation.
• Took over the Flutter-side Razorpay integration in a healthcare app, connecting backend-created test orders and implementing checkout success, failure, and cancellation handling.

Mobile Application Development Intern at Tech Genzi (2024-08 – 2024-12)

• Contributed to a React Native application using TypeScript across UI, navigation, API integration, debugging, and testing; independently completed an assigned Google AI API integration for an automated chat-reply module.
