I'm a Full Stack Developer with 5+ years of enterprise experience building web applications with .NET Core, React/TypeScript, and Azure — from designing REST APIs to deploying and running them in production. Most recently, I built SnapReceipt, a receipt-processing app using Azure AI Document Intelligence for OCR, Microsoft Entra External ID for authentication (MSAL, JWT), and per-user data isolation — deployed on Azure Static Web Apps. It reflects how I work: secure by design, cleanly structured, and shipped end to end. What I can help you with: REST API development and third-party integrations (ASP.NET Core, C#, Entity Framework) React/TypeScript frontends — responsive, maintainable component architecture Azure cloud work: Functions, Blob Storage, Cosmos DB, Key Vault, App Service, Static Web Apps, CI/CD Authentication and security: OAuth 2.0, MSAL, JWT, Microsoft Entra ID Database design and optimization with SQL Server and MySQL Document processing and OCR pipelines My career began in enterprise backend development in India (including IBM and Flextronics), and I now work in Swedish tech teams where I take full ownership of features from concept to production. I'm comfortable in agile setups, communicate proactively, and adapt quickly to existing codebases — I'd rather ask a clarifying question early than deliver the wrong thing late. If you need a developer who writes clean, well-tested code and keeps you informed at every step, let's talk about your project.
