Hi, I'm Rafael, 24, based in Pampanga, Philippines.
I combine code, AI and data analytics to automate repetitive work, uncover actionable insights and streamline workflows. Clients reduce manual effort by 60–80%, save thousands of hours, and make smarter, data-driven decisions.

Voice agents, automations and full-stack apps that answer, qualify and book leads, so the business runs without copy-paste.
Inbound receptionists and outbound callers on VAPI and Retell, connected to Twilio, n8n and your calendar. They pick up every call, qualify the lead and put the appointment in the diary.
Chat and email agents that answer from your own knowledge base (Supabase, RAG), draft replies for your team and hand off to a person when it matters.
n8n, Make.com and Zapier workflows that carry leads and data between your apps, from form fill to follow-up SMS, with no copy-pasting in between.
GoHighLevel, HubSpot, Zoho and Pipedrive set up to work for you: pipelines, lead routing, follow-up sequences and API integrations.
Full-stack apps built with Claude Code: command-center dashboards, custom CRMs and landing pages on React, Next.js and Supabase.
Scrapers, pipelines and dashboards in Python, SQL, Power BI and Looker Studio that turn raw data into numbers you can act on.
Client builds, demos and data projects. Filter by the kind of work you need.
Three options, depending on whether you need a plan, a long-term partner or a finished system.
Find the bottlenecks first
I map how leads, calls and data move through your business today, find where automation pays off first, and give you a ranked plan you can build from.
Part of your team, month to month
I work inside your team on an ongoing basis: building new automations, looking after the live ones, and fixing problems before your customers notice them.
From scope to launch
You know what you need. I design it, build it, test it against real scenarios and hand it over working, with documentation your team can follow.

"Rafael's AI Voice Receptionist has been a major upgrade for Luxe Roofing. It handles inbound roofing inquiries, schedules inspections, and even does outbound cold calls to our local neighborhoods. We're getting a steady flow of warm and hot leads without adding headcount, and the conversations still feel natural and professional."
"At King Caller, our entire model depends on consistent, high-quality calling. Rafael came in and built an AI Voice Receptionist that now takes care of inbound calls and outbound cold outreach to our target markets. The system identifies interest level, separates warm and hot leads, and sends structured data back into our workflows so our team can focus on closing instead of chasing."
"Rafael set up an AI Voice Receptionist that ran our $40 September tune-up promo to local neighbors, and the results were outstanding. The AI handled the outbound calls, explained the offer clearly, and booked appointments directly into our schedule. We saw a surge of new customers taking advantage of the heater tune-up promo without overloading our office staff."
"Rafael set up an AI Voice Receptionist that takes care of both inbound calls and outbound cold calling to our local areas. It qualifies roofing leads, collects the right information, and sends us only serious prospects. Our pipeline is fuller, our team is less overwhelmed, and we're closing more high-quality jobs."
"Rafael's AI automation solutions transformed our business operations. We reduced manual work by 70% and our team can now focus on strategic initiatives. Highly recommended!"
"The AI voice assistant Rafael built for our roofing clients has been a game-changer. We never miss a lead and our response time improved dramatically."
"Rafael's data visualization dashboards gave us insights we never had before. His expertise in Looker Studio and Python is exceptional."
"Working with Rafael was seamless. He understood our needs quickly and delivered a solution that exceeded our expectations. Professional and reliable."
