When a business wastes 10+ hours a week on manual processes that software should handle — that's the problem I fix. I build .NET-powered web applications that automate workflows, surface real-time data, and scale without breaking — for SaaS startups and operations-heavy businesses that need reliable backend engineering, not just "working" code. What that looks like in practice: → A logistics company needed real-time inventory updates across 12 warehouses. I built a Blazor + SignalR dashboard that eliminated their 4-hour manual reporting cycle entirely. → A document-heavy team was manually reviewing 200+ files per week. I integrated GPT-4 with ASP.NET Core to automate 70% of that review — deployed on Azure in under 3 weeks. → A growing SaaS product needed multi-tenant architecture before scaling to enterprise clients. I designed the role-based access system and Azure deployment pipeline that made that possible. My core stack: .NET Core / ASP.NET Core · Blazor Server & WASM · Angular 17 · Entity Framework Core · SQL Server · Azure (App Services, DevOps, OpenAI) · SignalR · Docker · Clean Architecture What makes the difference: I work with 3–5 clients at a time — never juggling 20 projects. You get my full attention, daily updates, and production-ready code with documentation. I ask the uncomfortable questions upfront so we don't hit surprises at sprint 3. If you're building a SaaS product, internal operations tool, or need AI added to an existing .NET app — send me a message with what you're working on. I respond within a few hours.

🚀 What I Help Businesses Do: ✔ Automate operations using AI (Claude, MCP, AI workflows, integrations) ✔ Build SaaS platforms from idea to production ✔ Replace manual processes with smart systems ✔ Improve performance, scalability, and cost efficiency ✔ Integrate APIs, third-party systems, and automation tools Technical decisions are business decisions.
