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

Senior backend engineer (Java, Spring Boot, Python) with AI built in. 4,100+ hours, $100K+ earned, 100% Job Success, and enterprise delivery for Apple, Fortune 50 food and beverage mncs, Vodafone, and Walmart. 👋 𝐇𝐢, 𝐈'𝐦 𝐆𝐨𝐩𝐚𝐥 𝐒𝐚𝐛𝐡𝐚𝐝𝐢𝐲𝐚. I've spent 13+ years in software engineering, and I've become the engineer teams trust when the backend simply cannot fail. I'm Expert-Vetted on Upwork (top 1%), Top 3% on Toptal, and a former Specialist Programmer at Infosys (their top 1%), where I built for Apple, British Petroleum, Vodafone UK, and Walmart. Right now I'm Tech Lead on a 500,000-user platform at US Pharmacopeia and a sustaining engineer on Fortune 50 food and beverage mnc's GenAI ordering system through Toptal. What that means for you: you're not handing your product to someone learning on your budget. You're getting an engineer who has already shipped the hard version of what you're trying to build. ⚙️ 𝗪𝗛𝗔𝗧 𝗜 𝗕𝗨𝗜𝗟𝗗 🔹 AI-integrated backends. RAG, LLM and agent workflows, vector search, wired into real Java or Python systems with Spring AI, LangChain, and the OpenAI and Anthropic APIs. Production, not demos. 🔹 Microservices that scale. Java 17/21 and Spring Boot, brittle monoliths broken into services that hold up under load. (Recently: a Java 8 to 25 migration with zero downtime.) 🔹 SaaS and FinTech platforms. Multi-tenant, zero-trust auth, payment and ledger logic that reconciles to the cent, audit trails, and the test pipelines that keep regressions out. 🔹 Full-stack when you need it. FastAPI, Flask, React and Next.js on top, so one engineer owns the whole arc from schema to screen. 📊 𝗪𝗛𝗔𝗧 𝗜'𝗩𝗘 𝗦𝗛𝗜𝗣𝗣𝗘𝗗 (𝗔𝗡𝗗 𝗪𝗛𝗔𝗧 𝗜𝗧 𝗥𝗘𝗧𝗨𝗥𝗡𝗘𝗗) ✓ $50M a year moves through a FinTech ledger I built. 99.99% accuracy, reconciles to the cent. ✓ 500,000 users sign in through a zero-trust auth platform I architected at US Pharmacopeia. ✓ 2,500+ venues run on Bar.Stream, where a human-in-the-loop RAG engine I built replaced manual product classification, and 200+ automations replaced manual data entry. ✓ 100% invoice-parsing accuracy from an AI agent I built for MPI, manual reconciliation gone. ✓ 60% faster APIs and zero-downtime modernization for 50,000+ educators on KigaPortal. ✓ 75% more API throughput on Apple's repair backend. Few engineers can put Apple, Fortune 50 food and beverage mncs, a $50M ledger, and production AI on one page. I can, and I can walk you through the architecture and the numbers behind every one. 🛠️ 𝗦𝗧𝗔𝗖𝗞 Java · Spring Boot / Cloud / Security / AI · Python · FastAPI · Node.js · RAG · LangChain · LLM + vector databases · OpenAI + Anthropic · PostgreSQL · MySQL · MongoDB · Elasticsearch · AWS · GCP · Docker · Kubernetes · CI/CD · microservices · event-driven 🌟 𝗛𝗢𝗪 𝗜 𝗪𝗢𝗥𝗞 You work directly with me. Not an agency, not a rotating team, and not a junior building it while a senior name sits on the invoice. I take your idea from a rough brief to a written spec, then I build it: architecture, code, the hard parts, and the reviews. I've carried year-long builds end to end on my own, so nothing gets lost in a handoff. I keep it efficient. You get working software and a clear weekly update, not a week full of standups. I'm on a call when it actually matters, and when something is at risk you hear it from me early, before it breaks. You set direction, I run the build. 📩 𝗟𝗘𝗧'𝗦 𝗕𝗨𝗜𝗟𝗗 𝗜𝗧 Send me a short note: what you're building and where it's stuck. Within a day you'll get a straight read back, how I'd approach it, the first risk I'd kill, and the one question I'd want answered before we start. If I'm not the right engineer for it, I'll tell you that too.
