Hi, I'm Redel Santos — I build scalable no-code and AI-powered systems using n8n, Make, and Zapier. From RAG pipelines and Voice AI agents to full custom web apps, I eliminate manual work and automate entire operations.
I build AI systems that work around the clock — Voice agents, RAG pipelines, and n8n workflows that replace entire manual processes. Intelligent. Scalable. Always on.
Start a Project →From no-code pipelines to full AI-powered applications — end-to-end, top to bottom.
n8n, Make, and Zapier pipelines that connect your tools and eliminate every repetitive task across CRM, comms, and data.
Retrieval-Augmented Generation pipelines for intelligent document retrieval and knowledge management. Your data, made searchable by AI.
Develop and deploy Voice AI Agents for automated client communication — 24/7 inbound handling, lead qualification, and follow-ups.
Bots and autonomous agents for business operations — Facebook page chatbots, inventory agents, spec calculators, and compliance tools.
Apify-powered web scraping at scale for lead capture, enrichment, and nurturing — fed directly into your CRM automatically.
Full web applications built with Claude AI and VS Code — multi-branch dashboards, POS systems, KDS, and full marketing automation platforms.
Built across industries — lending, manufacturing, food, contracting, and construction.
Problem: Wooden house manufacturers quote each client by hand — measuring AutoCAD floor plans manually, retyping numbers into Excel, pricing walls, windows, and roofing separately, then writing the offer letter in Word. A single quote takes 3–5 days, often losing the deal to a faster competitor.
Solution: MaderaPro is a full AI-powered quoting web app. Upload a DWG/DXF floor plan, the client's email, and handwritten site notes — Claude AI and OpenAI extract every dimension and requirement, compute a full price breakdown, and generate a ready-to-send XLSX pricing sheet and DOCX offer letter. No signup, no API key needed to try it.
Problem: Roofing companies still spend hours manually measuring roofs, calculating dimensions, preparing estimates, and creating reports for clients and insurance companies. Traditional roof inspection workflows are slow, labor-intensive, and prone to human error — especially when measurements are done manually on-site. Preparing professional documentation for insurance claims also takes significant administrative work, delaying project approvals and customer response times.
Solution: AHJIN Roofing System automates the entire roofing estimation and reporting workflow using satellite imagery, AI-assisted roof measurements, and automated PDF generation. The platform allows roofing teams to measure roofs remotely through satellite view, calculate roof dimensions and pitch data automatically, and generate professional estimation reports ready to send directly to clients or insurance companies — centralizing measurements, proposals, reports, invoices, work orders, and project workflows into one connected business platform.
Most POS systems stop at the receipt. Sale recorded. Receipt printed. That's it — nobody knows what ingredients were used, nobody knows how much stock is left, and nobody gets alerted when something runs low until it's already gone. Restaurant owners only find out they're out of stock when a customer is already waiting. That's too late.
I built NEXPOS so it never gets to that point. Every sale automatically deducts the exact ingredients used — sell a latte, the milk and espresso are deducted; sell a breakfast meal, the eggs, rice, and protein are deducted. Stock levels stay accurate after every single transaction with zero manual counting. When any ingredient drops below threshold, the system immediately notifies the supervisor, the boss, and the supplier — no one has to check, no one has to make the call.
Optional self-order kiosk lets customers place orders on a touchscreen, flowing automatically to the cashier and kitchen display. Same system. Zero extra manual work. Built for restaurants, bars, cafeterias, and coffee shops.
Problem: Important business calls can be missed or forgotten when call recordings are not reviewed manually. For managers or CEOs, this creates delays in follow-up, lost context, and no clear record of what happened during client conversations.
Solution: Phone Calls Capturer automatically checks GoTo call records every 30 minutes, filters the CEO extension line, and prevents duplicate processing. It then captures, transcribes, and summarizes the call using AI — sending the summary to Slack, logging the record in Google Sheets, and emailing the CEO with the full transcription and key points.
Street View-integrated pitch tool — drag to roof peak, select slope line, instantly calculates and outputs the roof pitch.
Problem: New leads fill a form but wait hours for a reply — sales team manually routes and follows up. Solution: Form submission instantly routes leads by type, OpenAI writes a personalized response, and the team gets notified on Gmail + Slack — zero manual work.
Problem: Closing a deal means manually creating a customer in Stripe, generating invoices, and notifying the team — taking 30+ minutes per deal. Solution: New Pipedrive deal auto-creates Stripe customer + invoice, AI drafts a payment summary, and routes alerts to Gmail + Slack instantly.
Problem: Researching leads and writing personalized cold emails manually takes an entire day per batch. Solution: Apify scrapes targeted leads from Apollo, OpenAI writes a unique cold email per prospect, and all data logs to Google Sheets — an entire SDR workflow on autopilot.
Problem: Every new account signup requires manual data entry into Airtable, writing a thank-you email, and pinging the team — repeated dozens of times a week. Solution: Form submission auto-creates the Airtable record, OpenAI writes a warm personalized email, Gmail sends it, and Slack gets the internal alert — fully hands-free.
Full RAG pipeline — Google Drive files are loaded, chunked, embedded via OpenAI, and stored in Supabase Vector Store. Webhook-triggered AI Agent retrieves relevant docs and responds via Voice AI for 24/7 intelligent client communication.
Problem: Missed calls from potential clients go cold — no one follows up fast enough and the lead is lost. Solution: Every missed call triggers an automatic SMS reply within minutes and logs the contact as an opportunity in the CRM — follow-up happens every time, zero manual work.
Problem: After a client signs a contract, reps manually generate and send invoices — causing delays and forgotten billing steps. Solution: The moment a contract is signed in GHL, an invoice is automatically created and sent to the client. Contract closed, payment on the way — instantly.
Problem: New form leads sit untagged in an inbox until someone manually creates an opportunity and sends a thank you — often hours later. Solution: Form submission instantly adds a tag, creates/updates the CRM opportunity, sends a thank you email, fires an internal notification, and sends an SMS — all in seconds.
Problem: After a form submission, follow-up is inconsistent — some leads get called, others get nothing, and hot prospects go cold. Solution: After a wait, GHL checks if the lead replied — if yes: tags them, notifies the team internally, and schedules a call; if no: sends a re-engagement SMS and loops back. No lead left behind.
Problem: Deals that go quiet for days fall through the cracks — nobody notices until it's too late and the prospect is gone. Solution: GHL automatically detects stale opportunities and runs a 2-stage re-entry pipeline — moving each deal back into an active stage so no opportunity is ever forgotten.
Problem: Customer chat replies go untracked — agents miss follow-up windows and warm leads lose interest waiting for a response. Solution: Every customer chat reply triggers an internal notification, updates the CRM opportunity automatically, and sends an SMS follow-up — zero missed conversations.
Problem: Support tickets flood in unfiltered — agents manually read, categorize, and route each one, burning hours every day. Solution: Webhook captures every ticket, OpenAI Agent Classifier reads and categorizes it, Switch routes to Draft Jira Ticket, Clarification, Human Review, or PM Escalation — then Slack notifies the right person instantly.
Problem: Appointment reschedules and cancellations require a human agent to answer calls, check calendars, and confirm changes manually. Solution: Retell AI handles the voice call — n8n backend processes reschedules, confirms cancellations with the caller, and auto-generates a call summary for every interaction. Zero human needed.
Problem: Store owners manually pull Shopify data every day, copy it to sheets, and write their own performance notes — taking 45+ minutes each morning. Solution: n8n auto-pulls daily Shopify orders, logs to Google Sheets, runs it through OpenAI for a written analysis report, then delivers the full summary to Gmail and Slack — every morning on schedule.
Problem: Dental clinics, gyms, salons, and coaching businesses each need phone-based booking support — impossible to scale with human staff. Solution: VAPI Voice AI handles all inbound calls — n8n backend routes Patient, Reschedule, Set Appointment, and Book Appointment flows with full Google Calendar and Sheets integration across four industries.
Problem: Teams receive dozens of emails daily with mixed attachments — invoices, PDFs, reports — and manually sorting them into Google Drive wastes hours each week. Solution: n8n monitors Gmail, marks emails as read, runs AI analysis on the content, splits and classifies every attachment, then auto-routes invoices, PDFs, and docs into the correct Google Drive folders — fully automated.
Problem: When someone books a Calendly call, reps manually add them to ActiveCampaign and create a Trello card — wasting time and causing missed onboarding steps. Solution: New Calendly booking instantly creates the contact in ActiveCampaign and adds them to the Trello onboarding board — zero manual CRM entry.
Problem: New leads from GHL don't reach the sales team in real time — they check manually and often miss hot leads at the peak of interest. Solution: GHL fires a webhook the moment a lead comes in → Zapier catches it and instantly posts the lead's details to a Slack channel — team sees it the second it happens.
Problem: Google Form responses need to be manually copied to spreadsheets and shared with the team — a repetitive task done multiple times a day. Solution: New form response auto-logs to Google Sheets across multiple spreadsheets and fires an instant Slack notification to the team — fully hands-free data collection.
