A. Backend Development & Microservices
· Design, develop, maintain, and optimize backend services and REST APIs using C# and ASP.NET Core / .NET Core.
· Design services using microservice architecture, clear service boundaries, maintainable domain/application layers, and clean architecture principles.
· Implement authentication, authorization, role/permission management, API validation, error handling, background processing, and secure service-to-service communication.
· Work with SQL Server and relational data access using Entity Framework Core; design efficient schemas, migrations, indexes, transactions, and queries.
· Implement distributed caching and cache invalidation strategies using Redis or equivalent technologies.
· Use RabbitMQ for asynchronous messaging, event-driven workflows, queues, retries, and reliable communication between services; implement real-time application features using appropriate technologies such as SignalR/WebSockets where required.
· Integrate MOAM systems with ERP (including Sage), CRM, payment gateways, SMS/notification services, Firebase, customs systems, and other internal or third-party platforms.
B. Frontend Development
· Develop and maintain responsive, secure, production-ready web applications using Next.js, React, TypeScript, HTML, and CSS.
· Integrate frontend applications with backend APIs, authentication flows, real-time features, and server-side/client-side data fetching as appropriate.
· Build reusable UI components, handle application state effectively, and ensure performance, accessibility, maintainability, and cross-browser compatibility.
C. Mobile Application Development
· Develop, maintain, and troubleshoot cross-platform mobile applications using Flutter and Dart.
· Integrate Flutter applications with .NET APIs and Firebase services such as Cloud Messaging/push notifications, authentication, analytics, or other required Firebase capabilities.
· Manage mobile application state, API communication, error handling, local persistence, release builds, and application performance.
D. DevOps, Server & Deployment Management
· Containerize applications and supporting services using Docker and Docker Compose; maintain reliable environment configuration across development, staging, and production.
· Administer and troubleshoot application servers, preferably Linux-based environments, including services, networking, ports, SSL/TLS certificates, reverse proxies such as Nginx, storage, permissions, and resource usage.
· Support CI/CD pipelines, source control workflows, environment variables/secrets, deployment automation, backups, rollback procedures, and production releases.
· Monitor application and infrastructure health and diagnose production issues across services, containers, databases, logs, queues, caches, and network dependencies.
E. Logging, Monitoring & Reliability
· Implement structured application logging using Serilog and centralized log monitoring/analysis using Seq.
· Design meaningful logs, correlation identifiers, health checks, metrics, alerts, and diagnostics to support distributed systems and production troubleshooting.
· Improve application performance, scalability, resilience, fault handling, and availability through profiling, testing, and operational monitoring.
F. Quality, Security & Engineering Practices
· Write unit and integration tests and perform API, frontend, and mobile validation before release.
· Apply secure coding practices for authentication, authorization, secrets, data protection, input validation, dependency management, and API security.
· Participate in technical design, sprint planning, backlog refinement, code reviews, Git workflows, troubleshooting, and documentation.
· Produce clear technical documentation for architecture, APIs, deployments, integrations, and operational procedures.
