112 projects, 100% success rate. I don't take on work I'm not confident I can deliver.
I help founders and teams turn an idea (or a half-working prototype) into a production SaaS or EdTech platform that actually ships and gets used — not just demoed. Most of what I build sits at the intersection of full-stack web development and AI: RAG systems, AI agents, chatbots, voice apps. But the AI is only there when it earns its place — if a plain database query is the right answer, that's what you get.
Projects I'm proud of:
💡 An adaptive SAT/ACT preparationplatform built with React, Node.js, and Python, powered by the OpenAI API and developed with input from Stanford PhDs — it turns raw practice scores into a learning path that adjusts after every session.
💡A RAG-powered document search tool, built with Python and LangChain and connected straight into SharePoint and Dynamics 365, that indexed 300,000+ internal files and cut research time by 75%.
💡A HIPAA-compliant AI note-taking tool, built with Node.js and Whisper on a secure cloud backend, that turns a psychiatrist's spoken session straight into a structured clinical note — saving hours of their paperwork time daily.
💡A voice-controlled drive-thru ordering system, built with React Native and Node.js, now running in real locations and cutting order processing time by 30%.
💡A GDPR-first Zendesk AI copilot, built with Node.js and the OpenAI API with a custom data-scrubbing pipeline, that drafts agent replies from ticket history while stripping sensitive customer data before it ever touches the AI model.
How I work with clients
I'm direct and to the point — you'll get plain answers on scope, cost, and timeline, and if something in your plan won't work, I'll say so early, not after the invoice. I think about your project with a business mindset first: what needs to ship, what it needs to earn or save you, and what can wait — not just what's technically fun to build. No jargon dumps, no vague "it's in progress" updates.
Full Stack Development Across Every Stack
As a Full Stack Developer Python and Python Full Stack Developer, I build AI backends with Django, FastAPI, and Flask alongside React frontends. As a Full Stack Developer React and Full Stack Developer React Node, my default stack for new SaaS builds is React/Next.js + Node.js and TypeScript. As a Full Stack Developer AI, I fold LLM and RAG features directly into that same codebase instead of bolting them on as a separate service — working with OpenAI, Anthropic Claude, Gemini, Mistral, and Llama models, orchestrated through LangChain, with vector databases like Pinecone and Elastic Search grounding responses in real data instead of guesses. Where a project needs voice, I bring in Whisper, ElevenLabs, and VAPI for speech-to-text and real-time voice AI, and I build autonomous AI agents and multi-step workflows using tools like Hugging Face and PyTorch when custom model work is called for.
For projects on a different foundation, I work as a Full Stack developer PHP and Full Stack Developer Laravel on legacy systems or client-mandated stacks, and as a WordPress Full Stack developer when a CMS site needs custom functionality beyond themes and plugins. I've also worked as a Webflow developer for fast, no-CMS-overhead marketing sites and landing pages.
Whether you need a Full Stack Web Developer for a browser-first product or a Full Stack app developer for something React Native-based on mobile (with Swift and Kotlin where a fully native module is needed), I own the project front-to-back — design, build, ship, and support. On the data and infrastructure side, I work with PostgreSQL, MongoDB, MySQL, and Supabase, deploy on AWS, Microsoft Azure, and Google Cloud Platform, and build with compliance in mind from day one — HIPAA, GDPR, SOC 2, and PCI-DSS — for HealthTech, EdTech, and enterprise SaaS clients who can't afford to get that part wrong.
If your project needs someone who'll own it end to end, send over what you've got — idea, spec, or prototype — and let's see if we're a fit.
