What stands out to me here is that this isn’t just a Salesforce customization role—it’s really about keeping Salesforce, .NET services, and Azure integrations working as one reliable system over the long term. The tricky part is usually not building individual components, but making sure data flows remain stable, secure, and easy to maintain as requirements evolve. If I were starting today, I’d first review the current Salesforce architecture, integration points, governor-limit risks, deployment process, and how Azure services are interacting with the platform. From there, I’d focus on tightening the integration layer, building or refining APEX and LWC components where needed, and making sure CI/CD in Azure DevOps supports predictable releases with proper testing and rollback paths. I’ve worked on enterprise systems where backend services and cloud integrations had to remain resilient under changing business requirements, and the biggest wins often came from simplifying integration logic and improving observability before production issues appeared. One thing I’d want to understand early is whether the primary workload is new feature development or stabilizing an existing Salesforce ecosystem with active integrations. Either way, I’m ready to jump in and contribute from day one.

Hello, This role is more than writing Apex—it is about building integrations that stay reliable as the platform grows. I would focus on clean Apex, LWC, .NET services, Azure DevOps pipelines, and secure REST integrations while keeping governor limits and performance in mind. One question: are the current integrations synchronous, or are you planning to use Platform Events or Change Data Capture for async processing? That choice affects scalability and system design. Good architecture should make deployments boring, production stable, and emergency calls almost disappear... everyone deserves at least one peaceful weekend! Best regards, Dev S.

Hi there, I understand you're architecting a hybrid system. Salesforce acts as the primary user-facing platform, while mission-critical logic, heavy processing, or complex integrations are offloaded to C/.NET backend services running on Azure. The entire development and release lifecycle for both platforms is automated and unified through Azure DevOps CI/CD pipelines. Technical approach: We'll use a decoupled architecture. Salesforce for UI (LWC) and orchestration (APEX). C/.NET Core Web APIs on Azure App Service for integration logic. Secure communication via REST/SOAP using Named Credentials. Azure Pipelines will manage SFDX source deployments and .NET builds from a central Git repository. Core modules: Custom Salesforce logic (APEX Classes/Triggers), a .NET Integration Layer (REST endpoints for external systems), Frontend Components (LWC for specific user workflows), and a unified Azure DevOps Pipeline for automated testing and deployment of both Salesforce and C codebases. Relevant systems: We architected Bison360, a full ERP that required deep, two-way integration with a client's Salesforce CRM instance using REST APIs for data synchronization. This mirrors your need for a hybrid system where Salesforce is a core, connected component. I have a few questions to clarify the scope. Regards, Rohit

Hi, This is a great fit for my background. I have built enterprise Salesforce solutions using Apex, LWC, REST APIs, Azure Services, Azure DevOps and C# .NET, including secure integrations with external platforms and CI CD automation. I focus on scalable architecture, clean code and long term maintainability, not quick fixes. For this scope, I recommend a budget of $4,000 to $6,000 over 8 to 12 weeks. The posted budget is quite low for a senior full stack Salesforce and Azure specialist. Happy to discuss your architecture and get started. Sahanaj

Your Salesforce-Azure integration will fail under load if you're not using Platform Events or CDC for real-time sync — polling APIs will hit governor limits and create data lag during high-volume transactions. Quick questions - are you planning to use Named Credentials with OAuth for secure external callouts? And what's your current Azure service bus architecture for handling async operations between .NET services and Salesforce? Here is the architectural approach: - SALESFORCE APEX + LWC: Build trigger frameworks with proper bulkification patterns and reusable LWC components that respect governor limits at 10K+ record volumes. - C# .NET + AZURE: Design middleware services using Azure Functions and Service Bus to handle bidirectional sync without hitting API rate limits. - CI/CD PIPELINES: Implement Azure DevOps pipelines with SFDX for automated deployments, including pre-deployment validation and rollback strategies. I've architected similar Salesforce-Azure integrations for 2 enterprise clients processing 500K+ transactions daily without governor limit failures. Let's schedule a technical call to review your data model and integration patterns before implementation.
