Company websites
Fast, responsive sites built to rank. Semantic structure, performance and technical SEO from day one, not bolted on later.
Rebuilt Gran Cursos Online marketing site: Lighthouse went from 7 to 76 on performance and 28 to 95 on SEO.
Web Developer for Custom Sites, Systems and Integrations
I build websites, web systems and integrations for companies that need software that actually works. Over 6 years of experience, remote, across Brazil.
What I do
Custom web systems and APIs
Platforms, admin panels and REST APIs built around your process, not a generic template. Backend, frontend and database.
Rebuilt an edtech platform from scratch in 6 weeks. It now has 5,143 users and 6,983 enrollments. Also designed 30+ REST endpoints for high-volume traffic.
Landing pages and SEO optimization
Campaign pages that load fast and convert. I also fix slow sites, indexing errors and pages that never show up in search.
Black Friday campaign pages that helped reach R$10 million in sales. At Grupo Estado, cut Google Search Console errors by more than 50%.
Automation and AI integration
Automatic transcription, content summarization, smart search and automation for repetitive work that eats your team hours.
OpenAI Whisper transcription in Portuguese, English and Spanish, transcript-based search, auto-generated lesson summaries and a question generator.
Marketplace, social and payment integrations
I connect your system to what you already use: payment providers, marketplaces, Instagram, TikTok and third-party APIs.
Integrations with Stripe, Instagram Graph API, TikTok API and Google APIs. On one anti-fraud integration, chargebacks dropped 40%.
Let's talk
I’m open to senior full-stack roles, remote. If you have a role that fits, send me a message — I reply quickly. I also still take on project work through my consultancy.
