MY PROCESS
1. Discovery — We begin by understanding your business goals, target audience, and the specific problems you want to solve. This shapes every decision that follows.
2. Design — We map out conversation flows, voice scripts, and integration touchpoints before writing a single line of logic, ensuring the experience feels natural for your users.
3. Build — Using the agreed platform (Botpress, Voiceflow, VAPI, or a combination), we build your chatbot or voice agent, connect your knowledge base, and wire up your chosen integrations.
4. Test — Every flow is tested for accuracy, edge cases, and real-world scenarios. We refine responses, tone, and fallback handling until the bot performs consistently.
5. Handover — You receive a fully working deployment, setup guidance, and support through the order chat so you can maintain and update your bot with confidence.

Frequently Asked Questions
The AI Chatbot can be integrated with websites, mobile apps, and social media channels including WhatsApp, Telegram, and Facebook Messenger, as well as customer support ticketing systems and CRM platforms.
VAPI is an AI-powered voice calling platform. The AI Voice Receptionist answers inbound calls (or makes outbound calls) on behalf of your business, handles common enquiries, qualifies leads, books appointments, and routes complex queries — all without human intervention. It is available 24/7 and speaks in a natural, conversational tone. Voice Receptionist functionality is included in the Enterprise package and can be added to lower tiers via the order chat.

To kick off your project we need: your chosen deployment platform or channel (website, WhatsApp, etc.), the primary use case (support, lead gen, voice receptionist, etc.), any languages required, your CRM or database details if integration is needed, and any existing FAQs, scripts, or brand guidelines you'd like us to follow.
Yes. From the Advanced package upwards, source code is included in the delivery. For Starter and Professional packages, the bot is fully configured in your own Botpress or Voiceflow account, meaning you remain in control of it.

See what our customers say about this Zinn
Rock solid freelancer. Reliable and gets the done job according to specification and timeline. Very happy. Will work with again.
On-time delivery, and even easier to work with him now as he's beginning to understand what we're trying to accomplish. I'll work with him again in the future; he sticks to the timelines, asks for clarification, and gets the work done and done right.
Great Service I would come back and recommended
Great service, helped build a great, efficient chatbot and taught me something new.
Another great experience. He's fast, asks for clarification if the requirements aren't clear, and has been able to push our initiatives forward quickly. We will continue to work with him on our next enhancements as well – he's great!
