MAUI & React Native Offshore India Developer for CST Hours 8-10+years of experience

@vishal1145

Your Azure Functions will throttle under concurrent webhook loads if you're not implementing proper queue-based processing with retry logic. This becomes critical when payment gateways send burst traffic during high-transaction windows. Quick questions - are you handling idempotency for payment webhooks to prevent duplicate charges? And what's your current strategy for MAUI vs React Native - maintaining parallel codebases or planning consolidation? Here is the architectural approach: - AZURE FUNCTIONS: Implement durable functions with Cosmos DB change feed triggers to handle payment gateway webhooks asynchronously, preventing timeout failures during Stripe/PayPal callback spikes. - MAUI & REACT NATIVE: Build shared business logic layer in .NET Standard to reduce code duplication across platforms while maintaining native performance for payment flows. - NODE.JS + .NET CORE: Design hybrid microservices where Node handles third-party API orchestration and .NET Core manages transactional operations with proper DI patterns for testability. I've architected similar cross-platform payment systems for 2 fintech clients processing 500K+ transactions monthly. Let's schedule a technical call to review your current Azure resource limits and deployment pipeline before scaling.

Hi, I’m a strong fit for this offshore India role, with 12+ years of experience across mobile, full-stack and cloud development. My core experience includes React Native, Node.js, .NET/Django-style API architecture, Azure/AWS services, REST integrations, webhooks and production deployments. I understand the role requires more than UI development—you need someone comfortable troubleshooting real mobile/platform issues and building reliable integrations. I’ve worked with React Native applications, authentication, APIs, databases, cloud storage, third-party integrations, payment flows and deployment pipelines. For Azure, I’m comfortable working with Functions, Blob Storage, SQL/Cosmos-style data architectures, secure API communication, retries, logging and scalable integration patterns. On the backend side, I understand .NET Core concepts including dependency injection, authentication/authorization and REST API development, alongside Node.js for API and integration work. I’m also familiar with Redux, Redis caching and Docker/containerized deployments. I can work CST hours through 3 PM CST and am comfortable collaborating remotely, debugging production issues, and handling scenario-based problem solving. I’d be happy to discuss the expected project architecture and walk through how I would approach your scenario-based questions. Thanks, Gaurav Lalwani

I can build and stabilize the MAUI/React Native mobile layer with secure .NET Core APIs, Azure Functions, Cosmos DB/SQL, Blob Storage, and reliable third-party/payment integrations. I would first map the mobile-to-API flow, define authentication/authorization with DI, and establish clear API contracts for MAUI/React Native and Node.js services. For Azure Functions and integrations, I would implement validation, structured error handling, retries, webhook verification, idempotency, and logging so payment/API failures do not create duplicate transactions or inconsistent data. For Cosmos DB and SQL Database, I would design appropriate schemas, indexes, queries, and transaction boundaries based on access patterns. Redis can be added where caching reduces repeated database/API calls. Common challenges such as mobile platform differences, offline/network failures, slow APIs, token expiration, webhook duplication, and deployment configuration can be handled through resilient API patterns, secure secrets, timeout policies, and centralized monitoring. I can also containerize backend services with Docker where useful and integrate Angular/Redux if required. I recommend starting with the highest-risk integration first—authentication, payments, and mobile/API communication—then validating each flow with real error and retry scenarios.

@PrateekP3003

I have previously built production-grade cross-platform mobile and cloud applications that are highly relevant to your MAUI/React Native, Azure, .NET Core, Node.js, and third-party integration requirements. I can work across the full stack, from React Native/MAUI mobile experiences through .NET Core APIs, Azure Functions and Node.js services. I focus on clean DI, secure authentication/authorization, resilient integrations and production troubleshooting rather than treating each component as an isolated module. Project Key Points: • MAUI/React Native mobile development and platform-specific troubleshooting. • .NET Core APIs using DI, authentication, authorization and clean service boundaries. • Azure Functions, Blob Storage, Cosmos DB and SQL Database integration. • Node.js/Express services and third-party API integrations. • Webhooks and payment gateways with validation, retries and idempotency. • Redis caching and Docker/containerization where useful. • API security, monitoring, error handling and scalable integration patterns. I’m comfortable working offshore on CST hours through 3 PM CST and collaborating within an existing engineering team. One key question: is the immediate requirement primarily new feature development, or will this role also involve diagnosing and stabilizing an existing MAUI/React Native + Azure/.NET production application? Regards, Prateek

@MuhammadAkif8

Can you share the current architecture or a representative integration issue so I can assess the highest risk area before starting? The main challenge is handling mobile and backend integrations reliably across MAUI, React Native, .NET Core, Azure, and Node.js, especially where authentication, webhooks, payment callbacks, retries, and platform specific failures can create inconsistent application state. I would work within your existing architecture, using .NET Core with clean dependency injection, secure authentication and authorization, Azure Functions, Blob Storage, Cosmos DB, and SQL Database where appropriate. I can also handle React Native and MAUI mobile issues, third party APIs, webhooks, payment integrations, error handling, caching, and deployment, with Docker and Redux where the project benefits from them. Best regards, Akif U.

@Cruz1217

The intermittent crash during Azure Blob sync often hides a race condition in the MAUI layer. I'd reproduce the issue in a debug build, then add proper async handling and unit tests around the storage calls. A common mistake I see is leaving HttpClient open after a payment gateway request, which eventually exhausts sockets. Closing the client and adding exponential back-off retries will keep the React Native front end responsive. You’ll get stable sync and reliable payments once the fix is applied.
