Chi sono
Hi, I'm Muhammad Zahid — a Sr. React Native Developer with 5+ years of experience building production mobile apps across healthcare, business, and logistics. I specialize in cross-platform apps (iOS & Android), REST API & Firebase integration, Stripe payments, NFC, Apple HealthKit, and AI-powered health tracking (Passio SDK, CGM/FreeStyle Libre integration). I've also built Progressive Web Apps (PWAs) for clients needing fast, installable web experiences. I turn your idea into a polished, scalable product — and stick around for support after delivery....

Esperienza lavorativa

HawkLogix_Pakistan

Sr React Native developer

HawkLogix Pakistan • Full time

Oct 2022 - Present • 4 yrs

Built the foundation of Hawk Logix's mobile products using React Native as the primary framework for cross-platform iOS and Android development, with Expo used on select projects to speed up build tooling, over-the-air updates, and simplified native module management. Structured app-wide state management using Redux, handling complex data flows across features like real-time health data tracking, chat/chatbot state, and multi-screen patient data — keeping the codebase predictable and easier to debug as feature complexity grew. Wrote application logic in TypeScript rather than plain JavaScript, catching type-related bugs before runtime and making the codebase safer to extend as multiple developers contributed to the same healthcare apps over time — a meaningful advantage on projects where data accuracy (like health readings) genuinely matters. Also contributed to React JS work for companion web dashboards where products needed a web-based counterpart to the mobile app, reusing logic patterns between the mobile and web codebases where practical. Implemented Flexbox-based responsive UI across all screens, ensuring layouts adapted correctly across different device sizes — from smaller Android phones to larger iOS devices — without breaking spacing or alignment, which was especially important for health-data-dense screens (dashboards, charts, integration lists) that needed to stay readable on any screen size.

GtechSources

Sr React Native Developer

GtechSources • Full time

May 2022 - Sep 2022 • 4 mos

Built and shipped multiple cross-platform mobile apps for veterinary app and business app clients — including DVM Central (VetAndTech), Vet and Tech, and GerVetUSA — covering educational resource platforms, medical supply/e-commerce integration for veterinarians, and CE course/webinar access for veterinary professionals. Handled third-party API integration to connect apps with external medical supply and resource databases, along with authentication integration and push notification setup using Firebase integration. Implemented social media login integration to simplify onboarding for end users across multiple client apps. Specialized in translating Figma to React Native and XD to React Native designs into pixel-perfect UI, working closely with design teams to match every spacing, color, and typography detail precisely. Delivered responsive mobile app design that worked seamlessly across both iOS app development and Android app development, testing thoroughly on real devices to catch platform-specific inconsistencies before release. Worked within compliance-conscious contexts — GerVetUSA in particular required close attention to FDA guideline adherence and ISO 13485 certified process documentation, giving me early exposure to building apps

Ignite

React Native Developer

Ignite • Full time

Jan 2022 - May 2022 • 4 mos

Worked as part of a dedicated development team building production React Native apps for FullStack's client base, including POS (Point of Sale) app development — building features for business owners to manage sales, accept payments, and run day-to-day operations from a mobile app. Implemented hardware integration for real-world retail environments, including receipt printer integration, cash drawer integration, and barcode scanner integration — connecting the app to physical POS hardware so businesses could run a complete point-of-sale system from a single device, across both single-location and multi-register/multi-location setups. Focused heavily on pixel-perfect UI implementation — translating approved design files into fully functional, responsive screens for iOS and Android, with careful attention to spacing, typography, and visual consistency. Prioritized clean, maintainable code architecture, writing reusable components so the codebase stayed scalable as new features were added. Collaborated closely with other developers in a fast-paced, deadline-driven environment, coordinating on shared codebases and ensuring features integrated smoothly. Applied strong analytical and problem-solving skills to debug hardware-integration issues quickly and keep delivery timelines on track. Gained hands-on experience with business management app development and retail/commerce app development — including customer profile management and multi-location business tools — which broadened my range beyond typical CRUD apps into real hardware-connected, commerce-focused solutions.

    Great experience. Muhammad understood the spec quickly, asked smart clarifying questions before building rather than assuming, and pointed out dependencies I hadn’t considered. He was flexible on payment timing and never pushed. Delivered working features for coaching and stayed available for feedback...

    Muhammad delivered exactly what was scoped and communicated the whole way through. He built out the Trends and analytics screens plus the inference API, and when he found the work connected to other parts of the spec, he flagged it upfront instead of quietly going over. He also explained clearly how...
