Hello! 👋 I’m a CTO, Senior .NET Core Developer, and AI Engineer with 20+ years of experience in C#, Microsoft Azure, cloud architecture, enterprise software, and Artificial Intelligence solutions. I help companies build scalable SaaS platforms, enterprise systems, internal tools, AI assistants, AI copilots, and production-ready AI products. As an AI Developer, I combine backend engineering with AI Development, Automation, API integration, and .NET Core architecture to create reliable Operational systems that solve real business problems. 📘 About Me I’m a technical leader with deep experience in software architecture, C# development, and .NET Core systems. Over the years, I’ve designed cloud-native platforms, distributed applications, Web API services, microservices, and enterprise backend systems for complex environments. My current focus is on Artificial Intelligence, AI Development, AI Agent Development, and practical Automation for business workflows. As an AI Developer, I build systems that connect LLMs, RAG, Azure AI Services, APIs, and business logic into stable products. The goal is not just to add AI features, but to create Operational value: fewer manual tasks, better decisions, faster delivery, and cleaner internal processes. As an AI Developer, I work across the full product lifecycle: discovery, architecture, backend logic, API integration, cloud setup, testing, deployment, and long-term support. I use .NET Core, Microsoft Azure, Orleans, RESTful architecture, and CI/CD to make sure every solution is secure, maintainable, and ready for real users. A strong part of my work is AI Development for SaaS products and enterprise platforms. I design Artificial Intelligence features, AI agents, AI assistants, copilots, workflow Automation, and API-connected systems that support real Operational needs. My background in .NET Core and distributed architecture helps me build high-concurrency applications that stay stable as usage grows. I also help teams modernize existing systems. As an AI Developer, I can review architecture, improve backend performance, connect AI services, build custom Automation, and turn fragmented workflows into one clear Operational process. 🛠️ Technical Skills C# & .NET Core Microsoft Azure & Cloud Architecture Orleans Distributed Virtual Actor Framework RESTful Architecture & Web API SaaS Development & Microservices Software Architecture & Design Patterns Artificial Intelligence solution design Artificial Intelligence architecture AI Development lifecycle .NET Core architecture AI Development for enterprise systems AI Developer implementation AI Agent Development & AI assistants Retrieval Augmented Generation LLM Prompt Design Azure AI Services API Design and Integration Automation workflows Operational system architecture MAUI & Blazor Angular DevOps, Kubernetes & CI/CD Aspire 🌿 Strategic Skills Enterprise Software Architecture Planning Artificial Intelligence strategy AI Development roadmap AI Developer technical leadership Automation planning Operational workflow optimization Cloud Migration & Optimization Performance Optimization Security & GDPR Compliance Cost Optimization Agile & Scrum Team Leadership Stakeholder Communication Technical Discovery & Roadmapping TOGAF Methodology Problem Solving 🏆 Certifications Microsoft Certified: Azure AI Associate Microsoft Certified: Azure Developer Associate Microsoft Certified: Azure DevOps Expert Microsoft Certified: Azure AI Fundamentals Xamarin Certified Mobile Developer Agentic AI developer, C# ai, ai integration, ai api integration,ai integration specialist, ai agent saas, ai saas developer, ai architect, ai solution architect, ai chat bot, ai chatbot saas, open ai chatbot, full stack developer, multi-agent, ai agent automation, ai automation agency, chatbot automation,, c# developer, c# .net, .net ai, .net developer, .net fullstack, ai agent builder, ai agent n8n, ai agent crypto, ai agent automation, rag, agentic rag, agentic rag, ai engineer rag, agentic rag, full stack app developer, full stack developer ai, artificial intelligence, artificial intelligence consultant, ai llm, llm agent, ai llm developer, llm chatbot, langchain agent, ai developer langchain, llm langchain, ai agent, ai voice agent, customer service agent, web developer, azure ai, azure ai studio, azure devops, azure architect, ai engineer, prompt engineer, product engineer, ai workflow, ai workflow automation, workflow automation, orchestration, ai prompt engineer, claude prompt, ai prompt engineering, ai prompt,prompt engineer claude, open ai developer, open ai chatbot, ai models, ai integration, ai integration specialist, ai integrator, ai api integrator, ai powered, claude certified.

Most startup founders burn 3-6 months and half their runway building an MVP the market never asked for. I help pre-seed and early-stage founders go from idea to a live, revenue-ready SaaS product in 4-6 weeks, using an AI-assisted development system that compresses build time without cutting corners on architecture. I have worked directly with SaaS founders and built a team along the way Exonix, where we engineer for what actually matters. In 4+ years, we've shipped 30+ SaaS products and 15+ AI-powered apps to real, paying users — not demos. What makes us stand out is our Clarity-first approach. This helps us differentiate ourselves from a savvy who does not understand what to build and what not to. We build SaaS platforms, AI-native products, and mobile apps (iOS/Android, on App Store and Play Store) using React, Next.js, Node.js, PostgreSQL, and AWS, plus GPT-4o, LangChain, Claude and vector databases (Pinecone) when the product calls for AI. Stack decisions are made based on your growth stage, not to pad a resume: pre-seed MVP and a product scaling to 50k users need different foundations, and I'll tell you which one you actually need. What I bring that a senior freelance developer typically can't: I've built this team from the ground up, and I've watched founders lose their runway to one specific mistake — choosing a stack or scope that looks impressive on day one but creates 6+ months of technical debt by year two. My job is to prevent that. I scope for validation first, polish for user-readiness second, and only then architect for scale — in that order, never reversed. If you're non-technical, I'm your technical co-pilot: making the architecture, team, and build-vs-buy decisions, not just writing the code. < MY ACHIEVEMENTS > - Launched 30+ SaaS products and 15+ AI/Generative AI applications over the last 4 years, from concept to paying customers - Grew Exonix from a solo freelance practice into a 50+ person team — now holding Upwork's Expert-Vetted badge, both individually and as an agency -Directly worked on or managed 200+ projects for founders and enterprises across the US, UK, Australia, UAE, Saudi Arabia, and Germany -AWS Certified Cloud Specialist, deploying infrastructure that scales without inflating your burn rate I work best with founders who have a real problem to solve and want technical direction, not just a coder taking orders. If you can tell me your stage, your idea, and what's actually blocking you, I'll tell you honestly whether we're a fit — and if a 4-6 week AI-assisted build is realistic for what you're trying to launch.
