Expertise

System Layers Select a Layer
  1. Fast, responsive websites and landing pages built end to end, like a bilingual format gallery and a searchable creative showcase, with structured data and sitemaps so they're built to be found.

  2. Server-side development in PHP and MySQL, running on AWS.

  3. Hand-built HTML5 ad formats for Google Marketing Platform: real HTML, CSS and JavaScript, wired to Enabler.js for Studio compliance, tested across every IAB size a campaign calls for and kept inside tight platform weight budgets.

  4. Advanced GSAP timelines that look great, load in a blink and still run smoothly inside a third-party ad server, plus After Effects motion work for campaigns.

  5. AI across the whole pipeline: code assistants for faster builds and QA, image generation for concepts, mood boards and campaign visuals, and video and voice generation for motion tests, storyboards and voiceovers. Every output is reviewed, refined and tested by hand before it ships.

  6. Visual design end to end: layout, typography and branding, social and display assets, photo retouching and compositing, interface design and motion graphics, all shaped by years as a web designer and built around the real limits of web and ad platforms.

  7. Training junior developers, owning the QA workflow and setting team-wide standards for how interactive formats are briefed, built, reviewed and shipped.
