Most businesses don’t lose customers because their product is bad, they lose them because nobody answered the phone, a lead got a reply too late, or booking was a hassle. I build AI assistants and automations that quietly fix that. 𝐖𝐡𝐚𝐭 𝐈 𝐛𝐮𝐢𝐥𝐝: • AI patient & customer assistants — answer FAQs and book/reschedule appointments 24/7 (website, WhatsApp, voice), even after hours. • Business automation — appointment reminders & no-show reduction, lead response, inbox triage, and dashboards that run themselves. • Custom AI builds & fractional CTO — for founders turning an AI idea into a reliable product. 𝐌𝐨𝐬𝐭 𝐑𝐞𝐜𝐞𝐧𝐭 𝐰𝐨𝐫𝐤: • AI dental assistant — booking, rescheduling & OTP confirmations, all done in natural language. • Automated patient follow-up voice agent • CTO-level AI engines for an EdTech platform (Spain) and an AI conversion SaaS (Australia) Also available for: broader AI agents, GenAI chatbots, Python backends, and data/ML work. 𝐖𝐡𝐲 𝐦𝐞:I don’t just “connect an API”. I build dependable systems you can trust with real customers and real revenue. Clear communication, fast delivery, and plain English (no tech-dictionary required). If you’re losing time or customers to manual work, message me and I’ll point out exactly where — no pitch, just the gaps.
