We are seeking an experienced Full Stack Developer with minimum 10 years of experience to design and develop modern cloud-native applications using React, Next.js, Node.js/.NET, and Azure services. The successful candidate will be responsible for building scalable web applications, developing secure APIs, integrating enterprise systems, and deploying solutions on Azure.

• Integrate frontend applications with backend APIs and Azure services.
• Optimize applications for performance, scalability, and usability.
Back-End Development
• Design and develop RESTful APIs and backend services.
• Implement business logic, data access, and integration services.
• Build scalable microservices and API-driven solutions.
• Develop secure authentication and authorization mechanisms.
Cloud & Azure Development
• Design and deploy applications using Azure App Services and other Azure-native services.
• Integrate applications with Azure Storage, Key Vault, Application Insights, and API Management.
• Support Infrastructure as Code and cloud deployment automation.
• Implement monitoring, logging, and operational support capabilities.
Integration Development
• Develop integrations with enterprise applications and third-party services.
• Design API contracts and service interfaces.
• Support event-driven and API-first architectures.
• Troubleshoot and resolve integration and performance issues.
DevOps & Engineering Practices
• Work with GitHub, GitHub Actions, and CI/CD pipelines.
• Participate in code reviews and technical design discussions.
• Follow secure coding and software engineering best practices.
• Collaborate with architects, product owners, and business stakeholders.
AI & Innovation (Nice to Have)
• Exposure to Azure AI Foundry, Azure OpenAI, or Copilot technologies.
• Experience integrating AI capabilities into business applications.
• Familiarity with AI APIs, chatbots, or AI-assisted user experiences.
