Hire the Best Microsoft HoloLens Developers
in the United States

I build AI-native systems, agent orchestration, and automation — the kind of work that usually takes a dev team months, delivered lean. Equally comfortable shipping a custom MCP server, a Tauri desktop agent cockpit, or a Power Apps frontend over a custom Python API. Core stack: Python (FastAPI, package development, automation), TypeScript/React (Tauri, Cloudflare Workers, Vercel), AI/LLM integrations and MCP server development, plus the Microsoft data stack (Dataverse, Azure SQL, Fabric, Power Platform) for enterprise engagements. Recent work: • A developer OS wrapping Claude Code with DAG-based YAML workflows, hook systems, and agent personas • A Tauri 2 + React desktop app serving as an AI agent cockpit — theming, persistence, multi-screen orchestration • An MCP server for content scraping and analysis pipelines • FastAPI proxy APIs for secure, role-scoped access to internal systems • Migrating 100+ legacy Perl scripts to a modular Python package — 50% maintenance reduction, 20% runtime improvement • A Microsoft Fabric + Dataverse + Azure SQL hybrid for enterprise BI I work best with clients who have real complexity — building something new in the AI/agent space, integrating with existing systems, or operating across both custom code and low-code.

I am an Entrepreneur, MIT grad and XR specialist having working on AR and VR for over 5 years. I have a background in both Software and Hardware, with two degrees from the Massachusetts Institute of Technology.

With over 35 years of professional experience developing Windows C++/C# desktop and web apps, I enjoy system programming, interfacing with hardware, and being thrown in the deep end. I am familiar with many technologies, including ASP.NET, SQL, Angular, WinForms, COM, Active Directory, Javascript, Typescript, OCR, and Git.

I build the 3D and the web app. Most browser-3D projects need two people - someone who can model it and someone who can code it. Both halves live here, which removes the handoff that eats your budget and your timeline. Top Rated Plus | 100% Job Success | 100 jobs | 1,000+ hours on Upwork | Kennesaw, GA - US-based, US time zone. === WHAT I BUILD === 3D PRODUCT CONFIGURATORS & CUSTOMIZERS - Blender source through optimized GLB, Shopify / headless commerce, AR viewer INTERACTIVE TRAINING & SIMULATION - Procedural trainers with real failure states, knowledge checks, analytics - Recent builds: a 7-stage turbofan engine trainer, and a Gram stain lab where taking the steps out of order actually ruins the slide REAL-TIME MULTIPLAYER 3D - Networked state, physics, dynamic lighting and line of sight (Three.js + WebSocket) SCIENTIFIC & STRUCTURAL VISUALIZATION - Real data, not artist impressions. Live PDB molecular rendering at 179,000 triangles in the browser RESCUE & OPTIMIZATION - Inherited, half-finished, or AI-generated Three.js that needs to ship and hold 60fps on a phone === STACK === Three.js | React Three Fiber | WebGL / GLSL | WebGPU | React | TypeScript | Next.js | Node | WebSocket | Postgres / Supabase | Blender (10+ yrs) | GLB/GLTF, Draco, KTX2, texture budgets === TRACK RECORD === - 10+ years in Blender, now applied to browser delivery rather than render farms - 63 completed Upwork contracts at 100% Job Success, 37 more in progress - Subcontracted 3D and animation work I have delivered has shipped to DoD, Medtronic and Meta programs - Built interactive 3D work for the David J.

I read and understand everything that ships, and if something is outside my depth I will tell you before you spend money, not after. I do not sugarcoat scope or timelines. You get a live staging link from week one, milestones with fixed scope, and replies inside 4 hours during US business hours. === START HERE === Send me your product page, your Blender files, or your broken Three.js repo. In a free 20-minute call I will tell you whether it is a two-week build or a two-month one, and what it will actually cost, before you commit to anything.

Lead developer for a VR arcade, a degree in computer science and frequent hack-a-thon attendee. I have worked with Unity3D for over 10 years on games and applications including virtual reality for Quest 3, Vive, Oculus, Windows MR, and HoloLens. I like to experiment with new tech and tools which gives me a lot of choices on how to design systems and solve problems.
