Hey, I'm Joshua.
I'm Joshua Mendoza — a GoHighLevel Expert, AI Automation Specialist, and Web Developer based in Antipolo City, Philippines. I co-founded NexSale Digital Marketing alongside my brother Jonathan and two close friends from our missions.
My technical foundation comes from studying full-stack web development, covering both front-end and back-end engineering. I've also completed GoHighLevel certification and Meta Ads certification — keeping my skills sharp and verified.
Over 3+ years, I've built systems for HVAC companies, business coaches, roofing contractors, e-commerce stores, and digital marketing agencies. In 2026 I joined Rayanova Agency and Regas Media, handling client onboarding, loading GHL snapshots, connecting AI chatbots via Appointwise, and setting up Zapier and Slack integrations. I also run Google and Meta Ads campaigns, creating video and image ad creatives using AI-powered tools and API integrations.
Most recently, I built a fully autonomous Social Media AI Agent using Claude Code in VS Code — a system that researches trending topics via Genspark and Gemini, generates visuals with Fal.ai and Nanobanana, then publishes AI-crafted posts across every major platform in a single click using Blotato and Postiz.
Let's work togetherPowered by the tools I use every day:
Returned Missionary
I served a 2-year full-time mission for The Church of Jesus Christ of Latter-Day Saints. That experience shaped everything — executive support, leadership coordination, scheduling, communication, and genuinely serving people. When you work with me, you get someone who truly cares about your success, not just the paycheck.
Core Values
Service-First Mindset
Two years serving God and His children trained me to put people first — every client gets my full commitment and genuine care.
Always Learning
I constantly explore new AI tools and platforms — from Appointwise and Claude Code to complex webhook architectures and AI-driven ad creatives. I stay ahead.
Systems Thinker
I don't just build features — I architect complete systems. From form to funnel to pipeline to paid ads and AI agents, every piece is designed to work together.
Clear Communication
Executive support experience from my mission means I communicate clearly, report consistently, and coordinate effectively.
