I don't just write code.
I build things that run.

Every project I take on is designed to create real, measurable impact — automated processes, faster response times, and systems that work without anyone watching.

🤖

Voice AI Agents

I build AI receptionists that handle real phone calls — booking appointments, answering questions, and managing cancellations via natural conversation. Powered by Vapi + GPT-4o.

⚙️

Workflow Automation

End-to-end n8n pipelines that eliminate repetitive tasks — automatic reminders, daily reports, follow-up emails, and data logging. Set it once, runs forever.

🔗

API & System Integration

I connect your tools together — Google Calendar, Gmail, Sheets, OpenAI, and more. If it has an API, I can make it talk to everything else in your stack.

Professional Experience

From hardware failure analysis to full-stack AI systems — a track record of building reliable solutions under real constraints.

AI Automation Developer
Freelance / Self-Employed
2025 – Present

Designed and deployed two production AI voice agents from scratch — Aria for a dental clinic and Ace for a sports & events venue. Both handle real calls 24/7: booking appointments, answering FAQs, capturing leads, sending confirmation emails, and logging everything to Google Sheets. Built the full stack: Vapi voice layer, GPT-4o reasoning, n8n webhook backend on Railway, and 7+ automated supporting workflows including daily summaries, event reminders, and call transcript logging.

Performed systematic failure analysis on electronic units — isolating root causes, producing detailed technical reports, and implementing corrective actions. Debugged new product models and trained operators on test machines. This engineering mindset of breaking down complex failures methodically directly shaped how I approach debugging AI systems and automation pipelines today.
