I build and maintain the backend systems that businesses depend on long after the initial build, API integrations, data layer architecture, and third-party connections that need to keep working reliably for years, not just pass a demo. One client has kept me on a single ongoing engagement for over three years, supporting and extending a data layer generation system. Another has had me as their long-term backend developer for more than a year. That kind of retention isn't an accident and it's what happens when the integration work underneath a system is solid enough that nobody needs to replace it. What this looks like in practice: — Long-term data layer architecture and code generation support (3.5+ years, ongoing) — JIRA API integration for real-time data sync between systems — Stripe and PayPal subscription billing logic built into .NET applications — WebSocket integration for live, real-time data feeds — MariaDB and SQL Server database development and query optimization — Entity Framework Core extensions for complex query requirements — Secure proxy API layers for service-to-service communication Tech stack: C# · .NET Core · ASP.NET Core · REST APIs · Entity Framework · SQL Server · MariaDB · WebSockets · Azure · Git If you need backend or integration work that has to hold up over time, not just ship once, that's what I do. I communicate clearly, scope honestly, and the clients I've worked longest with are the ones who'll tell you that.

With 23 years of software development experience, I have completed 80+ projects on Upwork with a Top Rated track record. My core stack is C# and .NET — from ASP.NET Core down to legacy .NET Framework 4.8 and ASP.NET Web Forms — paired with Angular and React on the frontend, and SQL Server on the backend. I also work with PostgreSQL and MySQL, using Entity Framework (both EF6 and EF Core) and Dapper depending on the project. Recent focus areas include: Azure & AI integration — Azure OpenAI features embedded into web and desktop applications, plus configuring Microsoft Copilot Studio for multi-agent orchestration and connecting AI agents to business data via Snowflake and MCP connectors. Performance & caching — Redis (including Azure Cache for Redis), T-SQL query plan and index tuning, for applications that need to stay fast under load. Payments & real-time communication — Stripe and PayPal integration, WebRTC for video features, and Twilio for SMS/voice. Healthcare software — I built and run a live medical e-directory platform (Angular/.NET), and spent 3 years at Prime Care Technologies, a U.S. healthcare technology company, so I'm comfortable working in HIPAA-regulated environments and handling protected health information. Desktop & on-prem deployment — WinForms/WPF applications, Windows services, and installers (WiX and Advanced Installer) for self-managed customer deployments. On the frontend I also work with Tailwind CSS, SASS/LESS, and modern build tooling (Webpack/NPM). I use Azure DevOps for source control, so changes are always revertible and progress is measurable. I follow consistent coding standards and document my work clearly so any developer who picks up the project after me can understand it. I work exclusively on hourly, pay-per-time engagements — happy to discuss your project in detail before we start, no obligation. Best regards, Srdjan Mladenovic
