? Design and build RESTful and GraphQL APIs that integrate seamlessly with internal platforms and external partners.
? Champion API-first development, driving consistency, reusability, scalability, and adherence to industry best practices.
? Define and enforce API standards (naming conventions, versioning, authentication/authorization) to ensure long-term maintainability and security.
? Collaborate with cross-functional teams to design semantic layers and canonical data models supporting eCommerce, ERP, and mobile systems.
? Develop efficient, secure, and scalable applications that perform reliably in high transaction environments.
? Leverage AI-powered development tools (e.g., GitHub Copilot, Cursor, Azure AI) to accelerate code generation, improve quality, and reduce rework.
? Use modern DevOps practices and tools (Azure DevOps, Git) to enable automated testing, CI/CD pipelines, and rapid feedback cycles.
? Apply best practices for application architecture, including layered design, modular coding, asynchronous programming, and clean architecture patterns.
? Identify and resolve performance, data, and integration issues using tools such as Postman, Azure Application Insights, and SQL Server Management Studio.
? Communicate technical designs and solutions clearly in verbal and written formats for technical and business stakeholders.
? Contribute to an Agile-SCRUM team environment, collaborating to solve challenges and deliver high-quality outcomes.

Required Qualifications:
? 7+ years of experience designing, developing, and supporting applications in cloud and/or on-premises environments.

? Proven expertise in API design principles (REST, GraphQL, OpenAPI/Swagger) with hands-on experience building and scaling APIs in Microsoft Azure.
? Proficiency in ASP.NET, C#, SQL, stored procedures, and data-access methods across various databases.
? Experience with Azure services such as Functions, App Services, and API Management (APIM) for governance, monitoring, and security.
? Strong understanding of DevOps principles, including automated testing, continuous integration, continuous deployment, and observability practices.
? Experience with API observability and troubleshooting tools (Application Insights, Postman Collections, automated contract testing).
? Experience with cloud-based messaging services (e.g., Azure Service Bus, RabbitMQ, Kafka) and designing event-driven architectures to support scalable, real-time integrations.
? Knowledge of software engineering fundamentals including SOLID principles, dependency injection, unit testing, and mocking frameworks.
? Practical experience with AI-assisted development tools (GitHub Copilot, Cursor, Tabnine, IntelliCode) for code generation, refactoring, and documentation.
? Knowledge of AI-driven testing frameworks for unit, integration, and regression testing automation.
? Expertise with web security, authentication/authorization, and OWASP principles.
