Want an AI feature that lives inside your product and actually does things for users: creating records, running workflows, pulling live data? That's what I build. I'm an AI integration engineer. I add conversational AI and LLM agents to products that already exist: a chat interface backed by a tool/function-calling loop that does real work in your app. I build to your spec and ship into your real codebase, and I'm careful not to break what's already running. Recent work: • Built the first in-app AI agent on Core Factors, a live B2B assessment platform: chat plus a multi-tool function-calling loop that performs real actions in the product, with human approval on sensitive steps. Shipped to written spec with no downtime. • Designed and shipped a full AI product solo as founding engineer: Hearth, an AI-powered dating app now live on the App Store. A SwiftUI iOS app, a Python backend on Google Cloud, an embeddings-plus-LLM matching engine, and a real-time voice agent over WebSockets. • Built patient-feedback tooling on the same platform: CSV contact intake, NPS surveys, AI sentiment and theme analysis on the free-text comments, and a dashboard that shows promoters, detractors, and the themes behind the scores, with HIPAA-aware PII handling. • Built Hearth Dating's public marketing site: a live React/TypeScript build with an embedded Claude-powered chat assistant, SEO prerendering, and CCPA/GPC consent engineering. On retrieval: I've built the pieces of RAG in production (embeddings, vector retrieval, LLM synthesis), and I've done structured extraction on scientific and clinical-adjacent data. I also use Claude at the deep end daily (Claude Code, Skills, MCP), and I've built onboarding that got a completely non-technical user doing real client work with it. Background: I'm a co-author on a machine-learning research preprint, applying deep learning to mass-spectrometry data. I've trained and evaluated models myself, and that shows up in how I design integrations around them. How I work: I use AI to write code, and I read and test every line before it ships. I'm direct about scope and quick to reply. Bring a written spec or a rough idea; either works. Stack: OpenAI · Anthropic Claude · Google Gemini · Python/Flask · PHP/Laravel · SwiftUI/iOS · React/TypeScript · REST · WebSockets · Google Cloud · Firestore. If you've got a product and want AI inside it, send me what you're trying to do and I'll tell you honestly how I'd approach it.

🚫 Avoid Costly Miscommunication and Poor Results On Upwork, many so-called “freelancers” are really project managers handling too many projects at once. They don’t do the work themselves, and worse, they often don’t even understand the work they’re managing. That means the “specialists” behind the scenes are often not true specialists at all—because if the manager doesn’t know the craft, they can’t ensure quality. The result? Confusion, delays, and outcomes that miss the mark—while you end up paying more. I’m different. I went through years of hands-on work, personally delivering 50+ successful projects and earning over $200k on Upwork alone—plus more outside the platform. Because I’ve done so much work by myself, I understand both the technical execution and the business goals—ensuring nothing gets lost in translation. Today, I still stay hands-on in my projects, but not alone—my clients and projects have grown too big for a one-person operation. I now collaborate with a trusted team and work with extremely high efficiency, so clients benefit from both clarity and speed without the typical overhead of project-manager setups.
