We are seeking a Senior Full Stack .NET Developer with strong hands‑on experience across front‑end, back‑end, and cloud technologies. This role requires deep technical expertise in .NET Core, C#, REST APIs, Angular, and microservices, along with experience building scalable applications on Azure (client explicitly mentions Azure & AWS, but Azure is mandatory and primary).

• Deploy and maintain applications using Azure services, including CI/CD pipelines through Azure DevOps.
• Contribute across the full software development lifecycle, from design to production deployment.
• Troubleshoot performance issues, optimize code, and ensure secure, high‑quality software delivery.
• Collaborate with cross‑functional teams while working independently as a senior‑level individual contributor.
• Provide detailed technical inputs and documentation for all implemented features and enhancements.

Required Qualifications

• 5+ years of experience with .NET Core, C#, REST APIs, microservices, and backend development.
• Cloud experience: Azure is mandatory; AWS exposure is a plus.
• 5+ years of experience with SQL, Cosmos DB, and NoSQL databases.
• Strong understanding of CI/CD pipelines, especially Azure Pipelines.
• Ability to work independently and provide specific, detailed contributions from past projects.
• Excellent problem‑solving, debugging, and communication skills.
