Need a senior architect who can build it, scale it, and make it beautiful, with AI woven through the whole thing instead of bolted on the side? That's what I do. I'm a principal full-stack architect and polyglot engineer, 15+ years taking products from idea to production across fintech, health-tech, cybersecurity, blockchain, defense, and AI. 💡 Work clients know me for: - A $500M real-time fintech trading platform (web + mobile) - A $100M real estate CRM built from scratch; the firm was acquired by Cushman & Wakefield - Solana indexing infrastructure handling $1–3T in daily transaction volume - A live algorithmic quant trading platform running real money on a tier-1 broker - Federated-learning threat detection for an AI cybersecurity platform - Solo-replaced a 10-developer offshore team on a national assistive-communication app 🤖 AI / LLM, where much of my recent work lives: - Production LLM systems with structured outputs, guardrails, and audit logging in regulated fintech - Multi-model pipelines (Claude, Whisper, Gemini, OpenAI, ElevenLabs) chosen deliberately for cost, latency, and accuracy - MCP and agentic tooling, with official Anthropic certifications behind it - A production AI agent and grounded voice-and-chat assistant on frontier models (Gemini, Claude, GPT), with real tool-calling into live equipment data, RAG over the actual manuals, a scorer, and an adversarial grounding eval harness that gates every deploy so it cannot hallucinate to users - Architecting specialized-model training on proprietary field data: fine-tuning small open models (Llama/Qwen) for domain tasks like fault diagnosis and failure prediction, with labeled eval sets and an eval-gated deploy pipeline - The discipline that keeps AI output reliable and affordable in production, not just impressive in a demo 🛠 Stack: - Full-stack: TypeScript/React/Next.js, Node/Deno, Python, Go, Rust, Ruby/Rails, PHP/Laravel - Mobile: Flutter, React Native, Swift, Kotlin - APIs & data: GraphQL, REST, PostgreSQL, MySQL, MongoDB, Redis - Cloud & infra: AWS, GCP, Supabase, Docker/K8s, CI/CD - AI: Claude, Gemini, GPT, MCP, multi-model orchestration - Security: PCI DSS remediation, federated learning, RLS/RBAC, signed webhooks 🎯 Clients hire me when: - They're launching something ambitious and want it architected right the first time - Their legacy codebase is a mess and they need someone who can inherit it and stabilize it fast - They want AI built into the product correctly, by someone who's shipped it in production - They want someone who thinks like an engineer, a strategist, and a founder I also direct and design large-scale sculptures and immersive environments. Fluent in product vision, UX/UI, and creative direction, with experience in Rhino3D, Unity, CAD, TouchDesigner, and Adobe.
