Most AI integrations look great in demos and fall apart three weeks into production. The context windows bloat, the agents loop, the RAG pipeline hallucinates, and no one knows why. I build the architecture that prevents that; proper chunking strategies, grounded retrieval, fallback handling, and deployment that holds under real usage. If your LLM is hallucinating outside its knowledge base, your RAG retrieval is returning wrong chunks, or your AI workflow is breaking between n8n nodes and your backend, that's the kind of problem I'm called in to fix. And build the right way from scratch when there's time to do it properly. ✦ What I build: » RAG systems & LLM integrations: OpenAI, Claude, Gemini APIs; LangChain, LlamaIndex, vector search with Pinecone, FAISS, Weaviate. » AI agents & multi-agent workflows: tool-calling, memory, orchestration, real task execution. » Workflow automation: n8n, Make, Zapier, Pipedream; event-triggered pipelines that run without supervision. » Full-stack web apps: Laravel, React, Next.js, Node.js, Python; from MVP to multi-tenant SaaS. » AI-powered internal tools: knowledge bases, ops assistants, document processors, compliance systems. ✦ Recent work I've shipped: » Built a multi-agent AI platform (React + Laravel + Python) with OpenAI, Gemini, and Claude integration, RAG pipeline, and role-based agent orchestration. The system handles real business workflows, not just chat demos. » Implemented AI fraud detection, automated product description generation, meta-ad analysis, and image creation pipelines using OpenAI, Gemini, and Claude for a large US-based e-commerce platform. » Built an AI ops assistant for a 30-year-old insurance consultancy, RAG-based chat grounded in approved SOPs, auto-generated agency-specific compliance guidelines from survey data, versioned document management. Audit handling time dropped by 45%, training ramp-up cut by roughly half. » Built an automated email management workflow using n8n, incoming emails classified by type, routed to AI reply generators with tone-specific prompts, logged to Airtable, and Slack-notified. Resulting in zero manual triage. » Built patient intake and therapy adherence systems for (NASDAQ: AHCO), HIPAA-compliant, Brightree-integrated, handling millions of patients across 40+ US states. Intake processing time reduced by 70%. » Built a hybrid care outpatient treatment platform for a NASDAQ-listed healthcare clinic, virtual + in-person care, symptom tracking, AI chatbot, HIPAA/HITRUST/SOC2/CURES compliant. ✦ Stack: » AI/ML: OpenAI, Claude, Gemini, LangChain, LlamaIndex, RAG, embeddings, fine-tuning, prompt engineering, n8n, Make. » Backend: Laravel, Node.js, Python, RESTful + GraphQL APIs, background jobs, multi-auth. » Frontend: React, Next.js, Vue, component-driven UI, real-time dashboards. » Databases: PostgreSQL, MySQL, MongoDB, Supabase, Vector DBs (Pinecone, Weaviate, FAISS). » Cloud & DevOps: AWS, GCP, Azure, Docker, Kubernetes, GitHub Actions CI/CD. » Healthcare: HIPAA, Brightree, Redox, Auth0, Twilio, HITRUST. I work best on projects that have real moving parts, systems that need to be reliable, not just impressive in a demo. If you're building something production-grade and need someone who handles both the AI and the engineering behind it, let's talk.

I build custom C# / .NET software for businesses that need reliable desktop applications, internal tools, and practical workflow solutions. My main experience is in Windows desktop development and business software. I work with C#, WPF, MAUI, ASP.NET Core, Razor, MVC, MVVM, SQL, Entity Framework, and Web API, and I’m also interested in Blazor-based internal applications. I’m a good fit for projects involving internal tools, workflow systems, document generation, printing features, integrations, and software that supports day-to-day operations. I work well on MVPs, prototypes, and milestone-based projects where the goal is to turn a business need into a practical working solution. I can take ownership of a project, communicate clearly, and make practical decisions to keep development moving. I can also help refine requirements as the project evolves. In many business applications, the best solution becomes clearer during implementation, and I’m comfortable helping shape that process while keeping the work structured and aligned with the client’s goals. I’m especially interested in .NET applications for internal platforms, admin tools, business automation, and AI-assisted workflow solutions where the technology supports a real business need. I usually prefer fixed-price or milestone-based projects when the scope is clearly defined, because it keeps the process transparent and predictable for both sides. If you need help building, improving, or supporting a .NET desktop application, internal business tool, or custom software solution, I’d be glad to discuss your project.
