Cover image for Most people think Claude Code

Most people think Claude Code just writes code. It doesn't. It builds systems and skills are how you make it build yours. Here's what a Claude Code skill actually is: A skill is a set of instructions Claude Code reads before it builds anything. → Instead of guessing how your tools work, it reads the exact rules you gave it then builds correctly the first time. → Think of it like onboarding a contractor. You don't want them guessing. You give them the manual. It knows your stack, not just generic code. → Without a skill, Claude Code builds something that looks right but breaks in your environment. → With a skill, it knows your exact tools, your exact setup, and your exact rules before it writes a single line. It saves you from fixing AI mistakes. → Vibe-coded builds break because the AI was guessing. Skills stop the guessing. → You get working output the first time not three rounds of debugging something that should have been right. It scales your business without scaling your headcount. → You write the skill once. Every future build inherits it. → One set of rules. Infinite consistent builds. Here's one I'd build right now: Retell AI skill. → Every voice AI project runs through Retell agents, phone numbers, functions, post-call analysis, all of it. → A skill for it means Claude Code knows exactly how to configure agents, wire up webhooks, and connect the stack without guessing the setup every single time. Build the skill once. Never explain your stack again. Follow Krittiya Clark (https://www.linkedin.com/company/109508261/admin/page-posts/published/?share=true#) - I document every build.

Cover image for Most plumbing companies don't have

Most plumbing companies don't have a lead problem. They have a phone problem. Owners think they answer nearly every call. The real number is closer to two-thirds. The average plumbing job is worth $300–$800. Most people who hit voicemail don't leave one. They just call the next plumber on the list. So every missed call is a job walking straight to your competitor. It was never a marketing problem. You already paid to make that phone ring. You just couldn't pick it up fast enough. → So I built an AI receptionist that answers every call, day or night. (With Retell AI) → It doesn't just take a message. It checks your actual Google Calendar on the spot, gives the caller real open times, and books the job. → The second the booking is confirmed, the customer gets a text with all the details automatically. → No double bookings. No phone tag. No jobs falling through because nobody got back to them. One recovered job pays for the entire thing. If your phone goes unanswered more than you'd like, this is the fix.🔥

Cover image for Most people think AI receptionists

Most people think AI receptionists are just chatbots on the phone. They're not. Here's the actual stack behind a real AI voice agent: → LLM APIs — the brain. GPT, Claude, Gemini — this is where the actual thinking happens. → Retell AI — handles the live phone call. Listens, responds, books. No human needed. → n8n — connects everything. If Retell is the person talking, n8n is the one actually doing the work behind the scenes. → Google Calendar — appointments land here automatically. Zero manual entry. → Google Sheets — lightweight CRM for call logs, lead data, client records. Five tools. One system. Infinite calls. This is the stack I'm learning to build real AI agents on.

Cover image for Every n8n workflow has the

Every n8n workflow has the same shape. Three parts. Every single time. Trigger → Processing → Action That's it. Let me break it down in plain English: Trigger → This is what starts the whole thing — a phone call ends, a form gets submitted, an email lands in your inbox. → Nothing runs until the trigger fires. It's the domino that tips everything else. Processing → This is the middle — where the workflow reads the data, makes decisions, and branches based on conditions. → "If the caller wants to book, go this way. If they want to cancel, go that way." Logic. Rules. No guessing. Action → This is the outcome — log the CRM, send the confirmation email, book the calendar slot, send a confirmation SMS. → This is the part the business actually sees. Everything before it exists just to make this happen correctly. Here's a real one from my own work: AI receptionist takes a call → n8n reads what the caller needed, checks which service they asked about, confirms the appointment details → books the slot in Google Calendar and sends the client a confirmation SMS. No human touching it. No appointment falling through the cracks. That's what n8n does. It takes the conversation and turns it into a business outcome. The AI talks. n8n does the work.

⚡ I fix broken systems and make workflows unstoppable

Cover image for Boost Your Revenue with Our $499 Instant Call Automation System

I just sold a $499 automation system to a scraping company. Not because AI is trendy. Not because automation sounds cool. Because speed protects revenue. They were generating inbound calls… but response delays were quietly killing conversions. And in business, momentum is money. So we built a system that: • Answers every call instantly • Eliminates missed calls completely • Qualifies and routes automatically • Requires zero manual handling No latency. No bottlenecks. No human dependency. Let me ask you something: But if a high-intent lead cools off before first contact, nothing downstream matters. Most teams obsess over funnels and ads. Speed isn’t operational. It’s strategic. Fix the response time. Everything else compounds.

The AI Trick That Closed $10K While I Slept

Cover image for Transformative Insights: AI Voice Agents in Real Estate Sales

The call that changed how I think about AI voice agents. I was reviewing a call recording for a client a real estate business running our Vapi AI agent on inbound leads. A prospect called asking about a property. Standard stuff. The agent handled it clean. Then the prospect said: "Actually, I'm not sure I'm ready to buy. My wife and I are still deciding." The agent didn't push. Didn't read from a script. It said something like: "That makes sense it's a big decision. Can I ask what's holding you back most right now?" The prospect opened up. Gave 4 minutes of real objection data. The agent acknowledged each one, offered relevant information, and suggested a low-pressure follow-up call. That prospect booked an appointment three days later. No human was on that call. No human wrote that response. The agent was doing what a great salesperson does — listening, adapting, and creating space. That's when I stopped thinking of AI voice as a cost-saving tool. It's a revenue tool. → I build these for service businesses. DM me if you want to see one live.

Cover image for Website Chatbot — The Magic

Website Chatbot — The Magic Dry Cleaners A website visitor shouldn't have to hunt for information or wait for a response. This chatbot handles them the moment they land. Built a conversational chatbot flow for The Magic Dry Cleaners that greets visitors, identifies their intent, and guides them down the right path. Visitors choosing dry cleaning get walked through item categories clothes, furniture, or other then introduced to the business and prompted to book. Those just browsing get a friendly hold message. Anyone asking who the business is gets a quick company intro with a call-to-action. Lead capture kicks in the moment someone shows buying intent, collecting their name before moving them forward. Friendly, on-brand, and built to convert browsers into bookings. Stack: Chatbot Builder · Conversational Flow · Lead Capture

Cover image for I had the incredible opportunity

I had the incredible opportunity to work on a cutting-edge project that involved building a real-time video avatar designed to answer all education-related questions. The client’s vision was clear: they wanted the avatar to be as realistic as possible, providing an interactive and dynamic user experience that feels natural, engaging, and truly human. After extensive planning and development, we successfully created an avatar that not only delivers accurate, real-time responses but also engages in meaningful, fluid conversations. The technology behind it integrates advanced AI models, computer vision, and real-time processing to deliver seamless interactions that feel like speaking to a real person.

Cover image for AI Cold Calling System for

AI Cold Calling System for Insurance Agencies | AI Voice Agent, Vapi AI, n8n Automation & OpenAI Integration An insurance agency needed a scalable AI cold calling system to automate outbound lead generation, reduce manual calling time, and improve appointment booking efficiency. The client wanted an AI voice agent capable of making outbound calls, qualifying insurance prospects in real time, and transferring high-intent leads directly to live insurance representatives. To solve this, I developed a custom AI automation workflow using Vapi AI, OpenAI, Twilio, and n8n workflow automation. The AI calling agent was trained to handle natural conversations, answer common insurance questions, qualify prospects based on predefined criteria, and route hot leads to human agents instantly. The system included conversational AI logic, AI voice automation, webhook integrations, and automated workflow triggers for seamless lead management. Using OpenAI API and conversational AI capabilities, the voice assistant delivered human-like interactions that improved customer engagement and increased response rates. I also implemented Twilio call handling and n8n automation workflows to manage outbound calls, lead tracking, follow-up automation, and CRM-ready data synchronization. The workflow reduced manual workload for the insurance sales team while improving operational efficiency and lead conversion performance. Key features included: AI cold calling automation AI voice calling agent Outbound call automation Real-time lead qualification Conversational AI workflows AI appointment booking support Twilio phone system integration OpenAI API integration n8n workflow automation AI customer support handling AI sales agent functionality CRM workflow automation AI receptionist capabilities Automated lead routing to live agents This project helped the client modernize their insurance sales process using AI automation, voice AI, and workflow automation technology while creating a scalable outbound lead generation system optimized for business growth.

Cover image for Problem: Enterprise demos are expensive,

Problem: Enterprise demos are expensive, slow, and often forgettable - so prospects never see the product's real value. Here's a repeatable, hands-on way ElevenLabs turned demos into a growth engine using Lovable (and you can copy it): 1) Define the demo outcome (2-3 minutes) • Pick one persona (GTM lead, engineer, marketing) and one measurable win you want to unlock (pilot sign-up, buy-in, cross-sell). 2) Choose a concrete scenario (3-5 minutes) • Make it visual and story-driven: e.g., a movie promo with interactive characters or a CPG brand with a voice-first support persona. 3) Assemble assets (5-10 minutes) • One short script/flow that shows product value in <90s. • 2-3 audio samples or prompts for voice/mood. • A single mock UI/frame (Figma or a screenshot) to embed. 4) Build the demo in Lovable (5-15 minutes) • Create the flow, wire the audio outputs to ElevenLabs voice + music models, drop in your mock UI, and set simple interaction triggers. • Test once. Iterate twice. Ship. 5) Use the demo as a sales asset • Hand it to your champion to run internally, embed in a prospect call, or include in a pilot proposal. Practical notes & impact • Timeframe: teams at ElevenLabs cut demo build time ~50% - 3-4 demos in the time it used to take to make one. • Outcome: faster sales cycles, more pilots, and direct cross-sell because prospects see multiple products working together. • Edge case: you can build a credible, working demo in the back of a cab - keep it focused and forgivable. Tools to use • Lovable - prototype + host the interactive experience • ElevenLabs API - voices & music for high-fidelity audio • Figma/screenshots - simple visuals • Optional: Make.com/Zapier for lightweight integrations Challenge: Pick one high-value prospect this week - 15 minutes, one persona, one demo. Build it. Share the link or the result here and I’ll give feedback. #demos #productdemos #salesenablement #productledgrowth #SaaS #gotomarket #ElevenLabs #Lovable #UX #productmanagement #sales #revenueops

This project involved

AI Virtual Tutor This project involved building a personalized educational experience using an n8n ai agent architecture. By analyzing the interaction flow, I set up a system where student queries are processed through a retrieval-augmented generation (RAG) pipeline. I used n8n automation to connect a frontend chat interface with a vector database in Notion, allowing the AI to pull from specific course materials. As an n8n workflow specialist, I ensured the api integration handled conversational memory, making this ai chatbot far more capable than a standard LLM. It’s a prime example of high-level ai automation designed for the future of EdTech.

I

AI Survey & Feedback Collector I engineered this AI automation to transform passive feedback into real-time business intelligence. The workflow starts when a user submits a response via Typeform or Google Forms, which triggers a make.com (http://make.com) scenario via a webhook. I integrated OpenAI to perform sentiment analysis and categorization on the text, then used an API integration to route high-priority "negative" sentiment alerts to Slack while archiving all data in Airtable. This make.com (http://make.com) automation (formerly Integromat) ensures no customer concern goes unnoticed, showcasing my expertise as a make.com (http://make.com) expert in sentiment-driven workflow automation.
