About me

WordPress & Laravel Developer with 8+ years of experience building custom themes, plugins, and web applications for clients across healthcare, hospitality, retail, and real estate.

I specialize in translating complex requirements into clean, maintainable code — from custom post types and ACF Pro integrations to REST API development, WooCommerce customization, and third-party API connections (Google Maps, Salesforce, CallRail, and more).

On the Laravel side, I've worked on Backpack CRUD systems, Sanctum authentication, Salesforce integrations, and multilingual email workflows.

03 — ToastBar – Stylized 3D Toast Factory

A playful low-poly toast factory brought from Blender to the browser. Slices of bread ride a conveyor belt through a toasting machine, pass under a glowing light beam, and come out golden while smoke drifts from the chimney, all running in real time with Three.js. The scene was first modeled and animated in Blender, then rebuilt for the web: the procedural Geometry Nodes animation was baked into a looping GLB, and Blender’s materials were recreated with custom GLSL shaders, including a toast shader that transitions from raw bread to toasted and a translucent smoke shader driven by animated 3D noise. A reusable particle system handles the smoke and sparks, while bloom post-processing, a volumetric-style light beam with real shadows, and camera constraints that keep the view inside the scene complete the experience. The project showcases a full Blender-to-web pipeline: turning a cinematic 3D scene into an interactive, performant browser experience.

04 — Interactive 3D Earth Globe

A cinematic, scroll-driven hero section built with Three.js. A realistic 3D Earth, complete with atmosphere, cloud layers, and a starfield, reacts to the user’s scroll: the camera zooms in on Colombia and animated arcs connect it to countries around the world, including the United States, Canada, Mexico, Spain, and Germany. The project explores how 3D storytelling can replace static hero banners, turning a simple scroll into a guided visual narrative. It’s well suited for agencies, travel and logistics brands, or any company that wants to show its global reach in a memorable way.

AI Tools & Generative Technologies

I am proficient in AI video generation using tools such as Seance and ComfyUI, where I design and execute generation workflows to produce high-quality AI-generated video content. Through ComfyUI's node-based pipeline system, I am able to fine-tune generation parameters, chain custom workflows, and integrate image-to-video and text-to-video models to produce content tailored to specific creative and commercial needs.

On the image generation side, I work with leading AI image models to create production-ready visual assets, concept art, and marketing materials, applying prompt engineering techniques and model-specific optimizations to achieve consistent and high-quality outputs.

I am also experienced with Claude Code, Anthropic's agentic coding tool, which I use to accelerate development workflows, automate repetitive coding tasks, and assist in building and debugging complex features across both WordPress and Laravel projects. Claude Code has become a core part of my development stack, enabling me to work faster and more efficiently while maintaining high code quality standards.

Beyond individual tools, I have hands-on experience designing and building AI agents — autonomous systems capable of performing multi-step tasks, interacting with external APIs, and making decisions based on context. This includes building agent-powered workflows for content automation, data retrieval, and task orchestration, combining large language models with custom logic to deliver intelligent, scalable solutions.

This combination of traditional development expertise and modern AI capabilities allows me to bridge the gap between conventional web development and the rapidly evolving world of AI-powered applications.
