I build production-ready web apps and mobile solutions that clients can actually ship — not prototypes. With hands-on experience in C#, ASP.NET Core, Flutter, and SQL Server, I deliver clean architecture and enterprise-grade code that scales. My current focus: integrating AI into real-world applications. I help businesses add LLM-powered features (OpenAI, Claude API, LangChain) into existing .NET systems — from intelligent document processing and chatbots to automated workflows. If you need AI that fits into your stack, not just a demo, I'm the right person. What I work with: → Backend: C#, ASP.NET Core MVC, VB.NET, REST & Web APIs → Frontend/UI: DevExpress, UI3, Razor Views → Mobile: Flutter (cross-platform iOS/Android), Kotlin (native Android) → Databases: SQL Server, MySQL — query optimization, schema design, EF Core → AI/ML: OpenAI API, Anthropic Claude API, prompt engineering, RAG pipelines I've worked with agency clients across business software, ERP Solutions, inventory systems, field service apps, and internal tooling. I understand deadlines, legacy code, and the difference between a clean proof-of-concept and software ready to hand off to a client. If your project needs a developer who won't need hand-holding on architecture, DM me with your brief.

Most SaaS companies are bleeding $5k–$50k/month on OpenAI/Claude APIs - and their legacy .NET code is blocking real AI adoption. I fix both. I architect hybrid LLM routers - where Claude Opus orchestrates high-level strategy, while local Qwen models (Ollama) handle 80% of inference execution. Result: 40–70% reduction in AI/cloud costs - proven in production at HiveGPT and Social27 (Fortune 500 event platforms). This isn't theory. It's deployed. It's saving real money. And I can do it for you - without rebuilding your entire stack. Most AI projects fail not because the technology doesn't work - but because the costs spiral before ROI kicks in. I have built and deployed production AI systems for Fortune-class clients (Social27, HiveGPT). The difference between a money-pit AI project and a profitable one is intelligent architecture - not just better prompts. What I do: I architect hybrid LLM systems where 80% of inference runs on local models (Ollama + Qwen) and only complex reasoning hits cloud APIs (Claude/OpenAI). The result? 40-70% reduction in AI spend - without sacrificing output quality. Why This Matters to You ----- If you are a SaaS founder: Your OpenAI bill is growing 20% month-over-month. My hybrid router cuts costs immediately. If you are a CTO: Your team is spending 60% of time on AI plumbing. I handle the infrastructure - you focus on product. If you are an agency: You are referring AI projects out and losing margin. I become your invisible AI delivery arm. What I Deliver ----- Hybrid LLM Architecture: Claude Opus as orchestrator + Qwen local sub-agents. Prompt caching reduces input costs by ~90%. Production-ready. .NET Core + Next.js Enterprise Systems: 18+ years building scalable SaaS platforms. Not just code - architecture that lasts. RAG Pipelines & Vector Search: pgVector, Azure AI Search, custom document ingestion - built for real-world enterprise data. Legacy Modernization: Take your ASP.NET monolith to .NET Core + AI-native in months, not years. Fractional CTO: Technical leadership for SaaS teams who need strategic direction without full-time cost. Proof - Not Promises ----- Social27 (Seattle, USA) Built an AI Online Event and Seminar - ChatGPT-powered live event intelligence for Fortune 500. Zero-downtime deployment at global scale with 50K+ concurrent users. HiveGPT (USA) Delivered a multi-agent B2B marketing automation platform. Achieved ~90% input cost reduction via prompt caching with fully autonomous campaign generation. Clearly Inventory (USA) Architected a multi-tenant SaaS inventory platform serving 100+ business accounts. 8+ years of continuous delivery with a fully remote team. Hospital OS Developed a HIPAA-compliant EMR/EHR with AI intelligence. Production healthcare system - built to meet strict compliance standards. My Technology Stack ----- AI / LLM: Claude API, OpenAI, Gemini, Ollama (Qwen 2.5/3/3.5), Mistral, Microsoft Semantic Kernel, RAG Pipelines, pgVector, Multi-Agent Orchestration, Prompt Engineering, Azure OpenAI. Backend: .NET Core 8/10, ASP.NET MVC, C#, Blazor, SignalR, Entity Framework, REST/GraphQL APIs, Microservices, Event-Driven Architecture. Frontend: Next.js 15, Angular 2-20, React, TypeScript, Vue.js, React Native, MAUI, Blazor. Cloud / DevOps: Azure (AKS, Functions, App Service, SQL, Synapse, DevOps, Blob), AWS EC2, Docker, Kubernetes, Terraform, CI/CD. Data: SQL Server, PostgreSQL, MongoDB, Redis, ElasticSearch, Azure Synapse, Power BI. Who I Work With ----- SaaS companies adding AI to existing products without rebuilding from scratch. Enterprises modernizing legacy .NET systems for the AI era. Agencies needing a white-label development partner for complex .NET/AI projects. Startups needing Fractional CTO leadership to guide technical strategy. The Bottom Line ----- I have been building enterprise systems for US clients remotely for 18+ years. I have seen the hype cycles. I know what works and what does not. AI is not magic. It is infrastructure. And infrastructure needs to be cost-effective, scalable, and maintainable. If you are spending more than $5,000/month on LLM APIs, I can show you how to cut that in half — without losing capability. Let's Talk Message me with: ----- Your current tech stack What you are trying to build or modernize Your rough LLM or cloud monthly spend I will reply with a high-level architecture assessment - free, with no obligation. Thanks
