With 𝟭𝟰+ 𝘆𝗲𝗮𝗿𝘀 architecting in the .NET ecosystem, I design C# .NET and cloud-native architectures that are built for the 𝟮𝟬𝟮𝟲 reality: scalable across AWS and Azure, secure by default, and wired for AI from day one. Whether you're a founder launching your first SaaS or a CTO staring down a legacy monolith that nobody wants to touch, I bring the technical leadership to turn that vision into something fast and maintainable. What I Actually Bring to the Table: - Legacy Modernization: I've untangled enough "spaghetti" .NET Framework (3.5/4.8) codebases to know that rewriting isn't always the answer.. but when it is, I migrate into clean, modular .NET 8/9 microservices that your team can actually work with. - AI & Automation: From Azure OpenAI to AWS Bedrock, I implement agentic workflows and RAG pipelines that automate the boring stuff and let your team focus on what matters. - Performance Engineering: SQL Server query plans, indexing strategies, cloud cost optimization, I've cut latency and slashed AWS/Azure bills by 30%+ more times than I can count. - Security-First Architecture: Zero-Trust, OAuth2, SOC2-compliant designs for fintech, healthcare, and anyone who can't afford a breach headline. The 𝟮𝟬𝟮𝟲 Stack I Work In: Backend: C#, ASP.NET Core 8/9, MVC, Web API, gRPC, SignalR, Blazor (Server/WASM) Frontend: Angular 19, React (Next.js), TypeScript, Tailwind CSS Cloud & DevOps: Azure (Functions, Logic Apps, Service Bus, OpenAI) · AWS (Lambda, S3, Bedrock) · Docker · Terraform · GitHub Actions · CI/CD · Microservices Architecture · Domain-Driven Design · CQRS · OAuth2 · JWT Data: SQL Server (optimization specialist), PostgreSQL, MongoDB, Vector Databases for AI/RAG pipelines Why 𝟭𝗖𝟰+ Years Matters: I've led teams, rescued failing projects, and shipped for startups and Fortune 500s alike. I speak ROI and Go-To-Market as fluently as I speak CI/CD. You'll not be hiring someone who just writes code, you'll get a technical partner who makes sure your technology accelerates your business instead of holding it back. Available for architectural audits, project rescues, or long-term development. Click 'Message' let's talk about where your project needs to go.
