I write code that loads fast and shows up on Google. The two have always gone together for me.

I started as an SEO analyst, then CRO, now I'm a developer. Five years across agency and freelance work, building e-commerce for education, energy, fashion and retail brands. Today I'm a senior full-stack engineer at Cogna Educação, owning the full enrollment journey. I built the internal CMS that generates landing pages with AI: an MCP server exposing our APIs to the models, a Strapi plugin for marketing to work with AI, guardrails and S3 publishing. Splitting pages into sections cut our token costs by almost 90% I was named employee of the year in CRO and e-commerce.

Things I've shipped.

CMS that generates landing pages via AI

live

MCP server connecting AI models to our offers and course APIs, with a Strapi plugin so marketing can build landing pages without engineering. Hallucination guardrails, a real-time cost dashboard, and almost 90% less token spend by splitting pages into sections.

AI-generated course content, human-reviewed

live

AI content generation for course pages, integrated into the institutional CMS. I built the moderation dashboard: nothing goes live without the content team reviewing and approving it first.

TypeScript · React · Node · AI · Strapi

Layered caching

live

In-memory + Redis in front of the highest-traffic platforms in the acquisition funnel, cutting origin requests and CDN cost.

Core Web Vitals obsession

employee of the year

SSR, SSG, or ISR: the choice depends on the page, not on preference. Structured data, Lighthouse in the green.
