Adam N.

Full-Stack Engineer | .NET, Java, React , AWS, AI/RAG/LLM & Healthcare

I build AI-powered applications that ship to production and survive contact with real users. 𝟏𝟔 𝐲𝐞𝐚𝐫𝐬 of full-stack engineering, now focused on AI agents, RAG, and LLM integrations. I work on a .NET, Java, React, and Angular foundation, which means I can also handle the parts that aren't glamorous: auth, deployment, databases, and a UI that doesn't make users cry. WHAT I BUILD ▸ AI Agents. Multi-step, tool-using agents that actually finish what you start them on. ▸ RAG Applications. Chat-with-your-docs, internal knowledge assistants, semantic search over private data. ▸ LLM Integrations. Adding GPT, Claude, Gemini, or open models into existing apps without breaking the rest of the codebase. ▸ Full-stack web apps. Angular or React on the front, .NET or Java on the back, cloud-native on Azure or AWS. ▸ Legacy modernization. Moving 15-to-20-year-old codebases into the present. I've done this three times, including a beloved baseball simulator with millions of simulated games. STACK I WORK IN Backend: .NET 8, C#, ASP.NET Core, Entity Framework, Python, Go, Java Frontend: React, Angular, TypeScript, RxJS, Storybook, design systems AI: OpenAI, Anthropic Claude, Google Gemini, LangChain, vector databases, RAG pipelines, agent frameworks Data: SQL Server, Redis, MongoDB Cloud: Azure (Web Apps, Functions, SQL, Storage), AWS (Lambda, EKS), Terraform, Kubernetes Auth: JWT, OAuth, Auth0, ASP.NET Core Identity RECENT RESULTS ✓ Built and shipped a Google Gemini-powered AI system for automated outbound patient communications inside a physical therapy EMR platform, deployed across a network of rehabilitation hospitals and university health systems. ✓ Rebuilt a 20-year-old baseball simulation app (millions of simulated games, loyal user base) from classic ASP to .NET 8 and Angular on Azure. Improved 90-day user retention by over 10% and unlocked a new design system for the product team. ✓ Architected and shipped a multi-tenant SaaS platform for the event registration industry, migrating from on-prem data centers to Azure PaaS. Grew revenue 10% through direct client work and cut IT infrastructure spend by 40%. ✓ Led cloud architecture for a national crop insurance carrier across AWS and Azure. Set up Terraform-managed infrastructure, mentored a team of dev leads, and shipped a Figma-to-production design system bridging design, product, and engineering. WHAT A RECENT CLIENT SAID "I hired Adam specifically because of his wide variety of experience and his profound level of skill. Over 18 months he proved himself to be an active and helpful member of the team. His versatility and engagement was crucial to our growth. I would enthusiastically recommend him." — Jason, BaseHit HOW I WORK I show up, I listen, I write code that holds up under load. I'm comfortable being the senior voice in the room or the quiet pair of hands, whichever the project actually needs. I won't pretend to know something I don't, and I won't talk you into AI when a SQL query would do the job. If you're building something AI-powered and want someone who can also handle the unglamorous parts (the auth, the deployment, the schema, the UI that doesn't make users cry), let's talk.
