Microsoft certified Azure and .NET engineer: Top Rated, 100% Job Success, 1,075 hours on this profile. I build and run production backends on Azure: .NET Core APIs, Azure Functions, Cosmos DB, Service Bus, and AI features built into the Microsoft stack. One engineer who owns the backend end to end: architecture, code, data, deployment, and the monthly Azure bill. Startups get senior output without an agency wrapper; enterprises get someone who has already worked inside their kind of stack, including a study engagement for an Upwork Enterprise client on Microsoft Fabric. WHAT I BUILD Azure cloud backends. .NET Core and ASP.NET Core APIs and microservices deployed on Azure App Service and Azure Functions, with SQL Server, PostgreSQL or Cosmos DB behind them, Service Bus queues between them, and Blob and Table storage where it belongs. Zero downtime deployments through Azure DevOps CI/CD pipelines. Data and integration pipelines. High-volume ingestion with Azure Functions and Azure Data Factory: telemetry, documents, third-party APIs, webhooks in both directions, OAuth-secured integrations, and monitoring so failures page someone instead of hiding. AI on the Microsoft stack. OpenAI and Azure AI features wired into real products: document drafting and review flows, retrieval over your own data, Power Automate cloud flows that chain PDF intake, AI drafting, approval and email. Certified in prompt engineering and generative AI (PMI, 2025). AI that ships inside the systems your team already uses. Azure cost optimization. Right-sizing App Service plans, consumption vs premium Functions, storage tiering and query tuning. A prior client hired me exactly for Azure resource cost management; most bills have 20 to 40 percent of waste hiding in plain sight. Frontends when the project needs the full stack. Angular and React UIs against those APIs, responsive and fast, including front-end refresh work a client rated 5.0 and described as "absolutely delighted". Modernization and migration. Legacy .NET to .NET 8, monolith to microservices where it pays, lift-and-shift to Azure done with functional parity tests so nothing silently breaks. I migrated a live energy monitoring platform to .NET 8 with an Azure Functions and ADF pipeline syncing SQL Server and Cosmos DB without losing a datapoint. Regulated and compliance-minded domains. Healthcare, insurance and fintech platforms built with the controls those industries expect: role-based access, full audit logging, encrypted data at rest and in transit, and workflow approval chains that leave a trail. My insurance management and bank statement processing builds run exactly these patterns in production. Node.js where the stack calls for it. Some products mix .NET services with Node APIs or need a lightweight Node backend beside the main platform. Comfortable in both worlds, same engineering standards in each, so you are not forced into a single-runtime decision the project does not need. RECENT PROOF 564 hours and a 5.0 on a single backend engagement (Zoocom EVO). A lead backend role (C#, .NET Core, MS SQL, TypeScript, Docker) closed at 5.0 with the review "Great developer. Exactly what we needed". A real-time digital cabin platform for flights: .NET 8 microservices, RabbitMQ, Azure Functions and CRON orchestration, audit-grade SQL Server design. Microsoft certifications on file: Azure Developer Associate (2021), ASP.NET MVC (Exam 486), MCSA Web Applications, plus PMI certifications in prompt engineering and generative AI (December 2025). HOW I WORK Clear scope before code: a short written plan with milestones and what each one proves. Daily updates in your channel, response inside 4 hours across US and EU working hours from IST. Thorough testing before anything reaches production, unit tests and CI gates included, and documentation your next hire can onboard from. Security by default: least-privilege access, secrets in Key Vault, OAuth done properly. Working inside an existing codebase is normal here: read first, map what is working, change only what the goal needs. And expect me to suggest simplifications: if a smaller architecture serves you better, that is what I will recommend, even when it means less work to bill. WHY THIS PROFILE OVER A BIGGER NUMBER Every hour on this profile was delivered by me, not subcontracted. 100 percent Job Success across 14 contracts, endorsed repeatedly for clear communication and reliability, available now and open to contract-to-hire. If you need a backend that runs on Azure, an API layer that will not fall over, an AI feature that actually reaches production, or an Azure bill that stops growing, send 2 lines about the project. You will get a concrete plan back the same day: architecture, milestones, timeline.
