Harrie Kevin Gallo
Harrie Kevin Gallofull stack developer and AI developer

I'm a full stack developer and AI developer based in Cebu, Philippines, working with clients across Europe, Asia, New Zealand, and the United States. When you partner with me you get one dedicated point of contact who takes your project from first idea to launch day, then sticks around to help you grow.

My career has been spent where websites meet real customers: shipping features and critical fixes for one of Asia's largest online learning platforms, keeping online stores selling for French jewellery brands, and delivering agency-standard work for New Zealand businesses at Plato Creative.

I'm equally at home in legacy and modern codebases, from PHP, jQuery, and WordPress through to React, Next.js, and Astro. Plenty of businesses run on a mix of both, and I enjoy meeting a codebase where it is: maintaining it, improving it, or migrating it when the time comes.

I work AI-native. Agentic AI is part of my daily stack: I orchestrate Claude Code, Cursor, and GitHub Copilot across real client work, and at Plato I build the AI solutions behind the web team, from Claude Code agent skills that automate maintenance and site builds to Model Context Protocol (MCP) integrations that connect AI agents to Craft CMS, Storyblok, and Statamic. Every AI-assisted change still gets human review, so projects move faster without cutting corners.

How I can help

Build, automate, and care for websites, online stores, and AI-powered workflows that earn their keep. Every service is scoped around a business outcome.

AI-native development
Agentic coding that ships faster, with review on every change. AI-native, agentic development with Claude Code and Cursor that takes websites and web apps from brief to launch in days.
Agentic AI & MCP integrations
AI agents that work inside the tools your team already uses. Model Context Protocol (MCP) integrations and agent skills that connect AI agents like Claude to your CMS and workflows, with guardrails.
AI-powered workflows & automation
Hours of busywork, handled while you sleep. AI-powered workflows, agents, and internal tools that save your team hours every week.
Page speed optimization
Faster pages, happier visitors, more sales. I find what slows your website down and fix it, so visitors stay instead of leaving.
Website maintenance & care
Your site stays healthy while you run the business. Updates, backups, monitoring, and fixes handled for you every month.

Jan 2026 - Present

Current role

Full Stack Developer (AI Tooling & Automation) · New Zealand

I build and ship client websites for a New Zealand creative agency, working AI-native in Claude Code and Cursor. I built the web team's library of Claude Code agent skills, which automate Craft CMS and SilverStripe maintenance passes, DDEV setup, and conversions of HTML prototypes into Astro and Storyblok components, and I connect AI agents to client CMS platforms through the Model Context Protocol (MCP), with human-in-the-loop guardrails on every workflow. Day to day I ship front-end and e-commerce features across Craft CMS, SilverStripe, WordPress, Statamic, and Storyblok, run maintenance and security updates on SiteHost, train clients on their CMS, and work with client services, marketing, SEO, and design teams.

Software Developer · Japanese e-learning platform

New features and critical fixes for NativeCamp, one of Asia's largest online English learning platforms, built with PHP (CakePHP), SQL, Angular, and Vue.js. As part of the dedicated bug team, I identified and resolved critical issues across the whole system, used AI coding assistants (GitHub Copilot, ChatGPT, and Gemini) daily to debug, generate code, and work through a large production codebase, and coordinated with Japanese senior engineers through daily stand-ups and progress reports.

Freelance Full-Stack Developer · US small businesses

More than 50 websites for US small businesses, mostly home-service companies, built on WordPress, Elementor, Bricks Builder, and Duda and hosted on WP Engine and Kinsta behind Cloudflare. I also rebuilt the Chitchat Confessions community platform on Next.js, React, TypeScript, and Tailwind CSS and migrated it with no downtime. AI-assisted development with GitHub Copilot, ChatGPT, and Gemini kept turnarounds short across a high volume of client sites.
