Role Objective:

Build and evolve a distributed system that spans: 

• On-premises Windows Services (Agent layer) 

• Cloud-hosted APIs and gRPC services 

• Real-time communication infrastructure (SignalR) 

• Multi-tenant database architecture 

• Web-based monitoring and administration dashboards 

 Key Responsibilities:

• Design and implement features across both Agent (on-prem) and Cloud tiers. 

• Contribute to architectural decisions including versioning, modularity, backward compatibility, and deployment strategies. 

• Develop real-time communication using SignalR (WebSockets) and gRPC (bidirectional streaming). 

• Implement resilient connectivity patterns (retry policies, reconnection strategies, durable messaging). 

• Manage multi-tenant data access using SQL Server and Entity Framework Core. 

• Own the Windows Service lifecycle and contribute to WPF-based desktop management tools. 

• Build secure, production-grade APIs using JWT, RBAC, and mutual TLS (mTLS). 

• Implement observability and reliability practices (OpenTelemetry, structured logging, Sentry, health checks). 

• Contribute to frontend development using Next.js for real-time dashboards and configuration portals. 

• Integrate with third-party platforms such as Salla, Shopify, and other e-commerce systems. 

• Design and implement event-driven patterns, CQRS, webhook processing, idempotent handlers, and rate limiting strategies. 

• Optimize performance using memory-efficient techniques (e.g., Span<T>, pooling, efficient serialization). 

• Work with Azure services (Azure SQL, Azure Identity, Azure DevOps) where applicable. 

• Apply ERP domain knowledge (invoicing, inventory, orders) when building business modules. 

• Follow Clean Architecture and SOLID principles with strong testing practices.
