Are you looking for a reliable, Senior-Level .NET Backend Engineer to build scalable SaaS platforms, optimize complex high-load databases, and deliver clean, enterprise-grade APIs? With approximately 3.5 years of hands-on, professional experience, I specialize in architecting secure, high-performance backend systems for demanding sectors like Healthcare, iGaming, and FinTech. I don't just write code; I apply modern System Design and Clean Architecture principles to construct robust solutions that solve critical business challenges and drive operational growth. 🔥 HOW I BRING IMMEDIATE VALUE TO YOUR BUSINESS: • Enterprise-Grade Backend Architecture: I engineer highly scalable application modules utilizing C#, .NET 8/9, and ASP.NET Core. I have extensive experience designing robust authorization logic for complex systems (managing 50+ distinct user roles) and implementing SignalR for sub-second, real-time data synchronization. • Advanced Database & Query Optimization: Performance under heavy load is critical. I have a proven track record of refactoring complex database logic for high-load transactional systems. By refining MS SQL Server stored procedures and table-valued functions, I resolve locking issues and have reduced query execution times by up to 35%, ensuring zero-latency financial calculations. • Seamless API & Third-Party Integrations: I lead the end-to-end integration of vital APIs. This includes payment gateways, game providers, and seamless wallets, consistently translating complex client requirements into stable technical realities. • Distributed Systems & Background Processing: I decouple resource-intensive tasks from core logic using Hangfire and Azure Functions, significantly improving overall system stability. Furthermore, I implement distributed caching layers with Redis, increasing data retrieval speeds by 40% and ensuring seamless system extensibility. • Cloud Infrastructure & DevOps Mastery: I guarantee high availability and 99.9% uptime by orchestrating microservices and deploying them across Azure and Kubernetes environments. I establish robust CI/CD pipelines via GitHub Actions to automate testing workflows and achieve a 99% deployment success rate. 🏆 FEATURED CASE STUDY: ENTERPRISE HEALTHCARE PLATFORM • Domain: Medical & Healthcare Systems • Tech Stack: .NET 9, C#, Angular, TypeScript, Azure Functions • My Role & Impact: I served as the core Full Stack Developer for a highly complex, secure, and large-scale medical application. I leveraged the bleeding-edge capabilities of .NET 9 to engineer a robust backend tailored for processing sensitive healthcare data. To optimize performance and ensure high availability, I architected and implemented critical background jobs using Azure Functions. On the frontend, I delivered a seamless, responsive, and intuitive user interface using Angular and TypeScript, bridging complex backend logic with an exceptional user experience. 💻 MY CORE TECHNOLOGY STACK & EXPERTISE: • Languages & Frameworks: C#, .NET 8 & 9, ASP.NET Core, Entity Framework (EF) Core, Angular, TypeScript, LINQ, REST API, GraphQL, SignalR. • Architecture & Design Patterns: Clean Architecture, Microservices, CQRS, SOLID principles, MediatR, FluentValidation. • Databases & Caching Solutions: MS SQL Server, PostgreSQL, Redis, SQLite. • Cloud, DevOps & Workflows: Azure (Functions, Blob Storage), Docker, Kubernetes, DigitalOcean, GitHub Actions, CI/CD. 🤝 WHAT TO EXPECT WHEN WORKING WITH ME: I operate with a product-owner mindset.
