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

Most AI projects fail because the infrastructure around them wasn't built to last. I'm an AI developer and Python developer who fixes that. I build RAG pipelines, AI Agent systems, and the backend architecture they need to actually run in production. When a project demands it, I bring in a trusted Python developer I've worked with long-term. Having a second Python developer and a second AI developer on call means you get the output of a full team without the overhead of managing one. 1. AI Systems That Go Beyond the Prototype As an AI developer, I design and implement custom RAG (Retrieval-Augmented Generation) pipelines that ground your LLMs in proprietary data: eliminating hallucinations and making responses genuinely useful. I build autonomous AI Agent frameworks that execute multi-step workflows without human input. Whether that means PyTorch for a custom machine learning model, TensorFlow for a deployment-optimized pipeline, or combining PyTorch and TensorFlow across different stages of the same system or computer vision for document parsing and image classification — I choose the right tool, not the trendiest one. My data scientist background means I treat model evaluation as seriously as model building. Nothing ships until the benchmarks prove it works. Every web development project I deliver goes through the same data scientist discipline: measure, validate, ship. 2. The Backend That Holds It Together A great AI developer still needs solid engineering underneath. As a Python developer, I build the infrastructure that makes AI systems reliable at scale: FastAPI and Django REST APIs, Flask microservices for lightweight integrations, Flask-based task queues for async jobs, PostgreSQL and MySQL schemas built for real data volumes, SQL queries optimized for performance, Docker-containerized services deployed through CI/CD pipelines with Git-managed version control. Data Scraping and web scraping are core to how I keep models current. I build Scrapy pipelines that continuously pull structured data from the web and load it into PostgreSQL or MySQL. That means your AI developer's models are always working with fresh information. I also use Scrapy for competitive research and e-commerce intelligence. Airtable provides non-technical stakeholders visibility into those Data Scraping pipelines, and Airtable webhooks trigger FastAPI or Django endpoints when records change. 3. Full Stack, Front to Back I'm a full stack developer and web developer, which means I own the entire delivery. React dashboards, Node.js middleware, JavaScript-heavy interfaces. I build the frontend that makes AI outputs accessible to real users. As a software engineer with web development experience across the full stack, I keep React components, Node.js services, and JavaScript logic clean and maintainable alongside the Python backend. I also have PHP developer experience. Many clients have existing PHP developer codebases, legacy CMS platforms, older systems that need to connect to modern Python APIs rather than be replaced. I know how to work with what's already there. 4. What Working With Me Looks Like You get a Python developer and AI developer in one person, backed by a trusted Python developer when the scope demands it. You get production-ready code - documented, tested, Git-managed, containerized with Docker, deployed through CI/CD. You get a data scientist mindset applied to every decision, a software engineer's standards applied to every line, a full stack developer's awareness of the full delivery chain, and a web developer's understanding that the end user is always the point. If you need an AI developer and Python developer who can take a project from first conversation to live deployment, I'd like to hear about it.
