AI chatbot built for a roofing business to handle site visitors 24/7. Homeowner engages instantly, books an inspection straight into Calendly without leaving the chat, and gets an automatic email confirmation with the calendar link while the lead's details route to the owner in real time. No missed forms, no delayed callbacks, no lost leads to competitors who answer faster.

Cover image for When someone visits your gym’s

When someone visits your gym’s website, they are at peak motivation. But if they fill out a form or interact with a chatbot, and no one follows up for hours (or days), that motivation cools down. They open another tab and look at the gym down the street. In the competitive fitness industry, speed-to-lead is your ultimate retention and growth strategy. ⚡️ Here is exactly how this seamless, dual-action AI workflow locks in memberships on autopilot: Phase 1: The Smart Homepage Chatbot 🤖 | A prospective member lands on your site and asks about pricing, classes, or amenities. The AI instantly handles their questions, captures their contact info, and segments them by fitness goals. Phase 2: The Instant AI Voice Agent 📞 | The second they drop their number, the system triggers a conversational AI voice agent. Within seconds, their phone rings. The AI agent connects with them dynamically, overcomes objections, and instantly schedules their first club tour or personal training assessment. The Result for Club Owners? No missed leads when your front desk staff is busy checking in members or running classes. Your website turns into a 24/7 lead-capture machine, and your calendar fills up with hot, confirmed appointments completely hands-free. Stop letting your website traffic walk away. Scale your member acquisition without adding to your team's administrative burden. 🚀 Want to deploy this exact speed-to-lead chatbot and voice ecosystem in your fitness facility? Drop a "GYM" in the comments below, and let’s connect! 👇

Full Stack Developer - for fast, scalable Websites & Web App

Cover image for I rebuilt my developer portfolio

I rebuilt my developer portfolio to attract better clients… not just show projects. I’ve been working on improving my portfolio with one goal: Make it clear for business owners what I can actually solve — not just what I’ve built. So I focused on: Clear service positioning (not just “I do everything”) Showing real use-cases (dashboards, SaaS, business websites) Simple user flow (so clients don’t get confused) Still, I know there’s always room to improve. I’d really appreciate honest feedback — especially from founders, agencies, or anyone who hires developers. What would you change? What feels confusing? What’s missing? Here’s the link: https://rittiksadhukhan.com/
