Support inbox triage

A controlled support workflow that turns Gmail requests into HubSpot tickets, unsent reply drafts and urgent Slack alerts, with a person in control of sending.

Connected tests verified tickets, unsent drafts and an urgent alert. Follow-up reused its ticket and preserved a reviewer-edited reply.

A decade in the making.

2016 to today

From WordPress and PHP to ecommerce, AI products, and marketing systems.

  1. 2016

    WordPress and PHP foundation

    Started professional web development in agency environments, building the PHP and WordPress foundation that still supports my work today.

    • Custom WordPress themes and client websites
    • PHP, CSS, jQuery, Git, and production CMS work
    • Collaboration with designers, marketers, and business owners
  2. 2017 to 2018

    Interface design and frontend craft

    This is where I began honing my eye for design. Working with Photoshop, Sketch, and Figma, I studied UI/UX fundamentals and became more intentional about how an interface looks, communicates, and feels to use.

    • Advanced Custom Fields and structured WordPress content
    • UI/UX design, color theory, typography, and visual hierarchy
    • Responsive layouts, spacing, feedback, and interaction details
    • Modern JavaScript, Sass, reusable components, and page systems
  3. 2019

    ViViFi agency work

    Founded a boutique agency and shipped client websites while learning how to scope work, communicate clearly, and deliver under real business constraints.

    • WordPress builds for small businesses and creatives
    • Client communication, revisions, launch work, and support
    • Reusable starter patterns for faster delivery
  4. 2020

    Chrome extension product work

    Moved beyond websites into product workflows by building browser tooling for ecommerce operations with my brother.

    • Chrome extension development
    • Browser automation workflows tied to business operations
    • Early product thinking around subscriptions, onboarding, and support
  5. 2021

    Light Code Labs and NFT systems

    Worked through faster moving product surfaces, including NFT launch systems, while continuing to sharpen WordPress, PHP, and modern frontend skills.

    • Technical systems for high traffic launch moments
    • Light Code Labs as the ongoing studio identity
    • React, TypeScript, and product architecture exploration
  6. 2022

    Burnout, travel, and reset

    After an intense run, I burned out and traveled. That chapter matters because it changed how I think about pace, focus, and the kind of work I want to build long term.

    • Travel through Peru, Thailand, Cambodia, Laos, and India
    • A reset around health, discipline, and direction
    • A clearer preference for useful product work over hype cycles
    • Began experimenting with generative AI in late 2022
  7. 2023 to 2024

    Applied AI and product exploration

    Started exploring an answer engine startup, experimenting with local models and the OpenAI API. Learned to connect models, retrieval, data, and automation into working products while continuing WordPress, Shopify, React, and TypeScript work.

    • Retrieval augmented generation (RAG), vector embeddings, and vector databases
    • Voice agent prototypes and visual automation workflows with n8n
    • Connecting APIs, retrieval, and business data into useful product workflows
    • Continued ecommerce, WordPress performance, and local SEO work
    • By late 2024, increasingly used ChatGPT and terminal workflows to turn ideas into working software
  8. 2025 to now

    Laravel platforms and AI product systems

    Brought that AI and automation experience into Light Code Labs Dashboard, my clearest portfolio example of AI connected to a working product. Built with Laravel, Inertia, React, TypeScript, PostgreSQL, and Docker, it connects captured business leads with enrichment, RAG and vector embeddings, and dynamically generated websites and content.

    • Laravel dashboard, queues, jobs, policies, and product workflows
    • Chrome extension lead capture feeding the Laravel application
    • Docker, staging, production, Hetzner hosting, and operational tooling
    • ChatGPT, terminal based coding tools, and specification driven implementation
    • Local tools and prototypes alongside ongoing agent and integration experiments
  9. Today

    Email and marketing automation

    Applying that engineering and AI foundation to email development, marketing automation, and the systems that connect a business with its customers. AI remains part of my daily workflow for exploring ideas, building software, and connecting tools.

    • Responsive HTML email development
    • Agent workflows, specification driven development, and review of the resulting code
    • Inspectable work and clear technical decisions
    • A continued focus on useful, maintainable systems

My experience, in one place.
