I build AI integrations, full-stack apps and agentic systems that save businesses real money — $75K a year for one client, 3 days of manual work cut to 30 minutes for another. 🔸 Top 1% Expert-Vetted 🔸 100% Job Success 🔸 $400K+ earned 🔸 4,000+ hours. Bonus: I also train clients on AI
AI integration live in 2–3 weeks. Full SaaS MVP in 8–12 weeks. Production systems, not prototypes.
17 years in software — CTO of a healthcare startup, engineering leader on Fortune 500 accounts, and for the last 8 years running my own AI and development practice. You get architecture decisions and business judgment, not just code.
🏗️ WHAT I BUILD
➡️ AI Integration & Agentic Systems — Claude and OpenAI built into the tools you already run. Document processing, research, outreach, support, operations (Claude Agents SDK, OpenAI Agents SDK)
➡️ Full-Stack & Mobile Apps — AI native full stack developer with Claude Code Max Pro plan and built multi-tenant SaaS, marketplaces, internal platforms, iOS and Android (React, Next.js, Node.js, Python/FastAPI, React Native, Flutter)
➡️ AI-Powered SaaS & Chatbots — knowledge-base assistants, AI personas, and LLM features inside real products
➡️ Voice & SMS AI Agents — phone agents for calls, bookings, intake, and support, including full call-center automation (Retell, VAPI, Twilio, ElevenLabs)
➡️ Data Pipelines & BI Dashboards — the data layer your AI actually needs (Power BI, Microsoft Fabric, Azure Data Factory)
➡️ Workflow Automation — n8n, Make, Zapier
📊 SELECTED WORK — BUILT TO PRODUCTION
🔹 Document Extraction Agent — multi-format PDF to CRM pipeline for a US cost analyst firm. Saving $75,000 annually.
🔹 Multi-Tenant B2B SaaS — wholesale buying platform for Australian fashion retail. MVP in 8 weeks, 200+ stores onboarded, running live for over 2 years. Stripe billing, role-based access, inventory and order management.
🔹 AI Content Platform — agentic SEO system for an Icelandic travel company, replacing two full-time content creators.
🔹 HIPAA-Compliant Health SaaS — clinical workflow platform plus iOS and Android apps, both live on the stores, with EHR sync and Twilio voice/SMS.
🔹 Voice AI Call Center — financial services client in the Netherlands. Retell + VAPI + Python FastAPI, Twilio SIP trunking, automated follow-up, post-call transcription and CRM sync.
🔹 Data Platform & BI — end-to-end ETL, warehouse and reporting for an insurance company. Data prep went from 3 days to 30 minutes.
⚙️ HOW I WORK
🔹 Free discovery session — I map your process, pressure-test the idea, and tell you honestly whether AI is the right answer. Some clients leave this call knowing they don't need me yet.
🔹 Architecture and scope — clear technical plan, timeline, and success criteria before any code.
🔹 Build in sprints — working software you can see and use every week, deployed automatically.
🔹Launch and handover — documentation, training, and support so you're not dependent on me forever.
