About

I’m a software engineer with over ~6 years of experience in technology, primarily focused on modern front-end development (React, Next.js, TypeScript) and scalable application architecture.

I have hands-on experience with e-commerce platforms (VTEX IO, FastStore), technical SEO, REST API integrations, and OAuth2 authentication flows, plus Python-based automation and ETL pipelines.

This portfolio was built with Next.js (SSR), Supabase as a backend, relational modeling with JSONB, RLS policies, and a CI/CD pipeline via GitHub Actions — connecting frontend, database, and DevOps into a clean, scalable architecture.

I value pragmatic solutions, maintainable code, and metrics-driven decisions.
