I'm a Senior Solution Architect and Technical Lead with 14+ years of experience designing, architecting, and delivering enterprise-grade SaaS, cloud-native, and AI-powered applications using the Microsoft technology stack. I specialize in building scalable, high-performance software solutions from architecture to deployment. Whether you're building a new SaaS platform, modernizing a legacy application, integrating AI capabilities, or scaling an enterprise system, I can help turn your vision into a production-ready solution. Unlike larger agencies, you work directly with the architect who designs, develops, and delivers your solution. This means faster communication, technical clarity, high-quality engineering, and complete ownership throughout the project lifecycle. I focus on delivering software that is scalable, maintainable, secure, and built for long-term growth. ━━━━━━━━━━━━━━━━━━ 🚀 Core Expertise ━━━━━━━━━━━━━━━━━━ ✔ Solution Architecture & Technical Consulting ✔ Enterprise SaaS Platform Development ✔ Multi-Tenant SaaS Architecture ✔ ASP.NET Core, .NET & C# ✔ Azure Cloud & Cloud-Native Applications ✔ REST APIs & Microservices ✔ AI Integration (Azure OpenAI, RAG, AI Agents) ✔ Angular Full-Stack Development ✔ .NET MAUI Cross-Platform Applications ✔ Legacy Application Modernization ✔ Performance Optimization & Architecture Reviews ━━━━━━━━━━━━━━━━━━ 🤖 AI & Modern Development ━━━━━━━━━━━━━━━━━━ I help organizations integrate modern AI capabilities into their applications using: ✔ Azure OpenAI ✔ AI Agents ✔ Retrieval-Augmented Generation (RAG) ✔ Model Context Protocol (MCP) ✔ Semantic Search ✔ Intelligent Chatbots ✔ Knowledge Base & Enterprise Search ✔ AI Workflow Automation ━━━━━━━━━━━━━━━━━━ ☁ Technology Stack ━━━━━━━━━━━━━━━━━━ **Backend** C#, .NET, ASP.NET Core, Web API, SignalR, Entity Framework Core, MediatR **Frontend** Angular, TypeScript, JavaScript, HTML5, CSS3, Bootstrap **Cloud** Microsoft Azure, Azure App Services, Azure Functions, Azure Storage, Azure Service Bus, Azure DevOps, Docker **Databases** PostgreSQL, SQL Server, MongoDB, Redis **Architecture** Microservices, Clean Architecture, Domain-Driven Design (DDD), Event-Driven Architecture, CQRS, API Gateway, Multi-Tenant SaaS ━━━━━━━━━━━━━━━━━━ 🎯 Ideal Projects ━━━━━━━━━━━━━━━━━━ ✔ SaaS Product Development ✔ Enterprise Web Applications ✔ Solution Architecture ✔ AI-Powered Business Applications ✔ Azure Cloud Migration & Modernization ✔ Microservices & API Development ✔ Long-Term Product Engineering ✔ Technical Leadership & Architecture Reviews If you're looking for a Solution Architect who can design scalable systems, build enterprise-grade applications, integrate modern AI capabilities, and lead projects from concept to production, I'd be happy to discuss your requirements.
