Full‑stack developer – AI images & payments
Built an MVP using Lovable.dev (http://Lovable.dev), Supabase, and Stripe that turns 4 uploaded photos into cinematic black-and-white portraits via the OpenAI Images API. Users upload exactly four images, which are validated and processed through an AI pipeline. Unpaid users get watermarked previews; full-resolution downloads unlock via Stripe. Includes a dark, cinematic UI and a “generate another” flow.

Protect your business and customer data when using AI Voice Agent
A dental clinic needed a HIPAA-compliant AI voice agent to
automate calls and protect patient data. I built a local voice system with
on-premise STT, ensuring no audio left the clinic. Each booking synced to the
CRM and doctors’ Google Calendars via secure OAuth, with all data encrypted
(AES-256). I added anonymization, 30-day auto-deletion, and audit logs to meet HIPAA. The clinic reached 100% compliance, cut booking errors, reduced staff workload by 70%, and ensured full data privacy and security.

Client was a Managed Services company that provided IT
Infrastructure to mid-sized clients. This was a series of automations that acted as Level 1 support. The first n8n workflow monitored their support email inbox for incomming service requests. If the request did not have all the required information it triggered an outbound call from our AI assistant that would interview the customer to gather all the requirements before
completing the service request. Password resets, create and manage O365 Distribution Groups and shared mailboxes, etc...
