About me

My name is Fernando Alves (🇧🇷), I’m a Software Engineer based in São Paulo and I’ve been building for the web for over 15 years. I focus on scalable front-end architecture, micro front-ends and moving legacy systems to cloud native architectures, with an eye on stability, accessibility and high availability

Where I’ve worked

• Kamino (2024 – 2026), Frontend Engineer: led the architecture of the migration from legacy ASP.NET MVC systems to React, cutting screen delivery from 3 weeks to under 5 days. Shipped zero-downtime dark releases with feature toggles, built an analytics deduplication architecture for 1,200+ active environments and standardized accessibility (WCAG) and internationalization across teams
• Freelance (2023 – 2024), Frontend Consultant: architected solutions for B2B platforms, including a white-label React checkout scoring 90+ on Lighthouse
• PagSeguro (2021 – 2023), Software Engineer: built Next.js micro front-ends for back-office and accounting, cutting operational data retrieval time by 90%. Worked on Jenkins CI/CD pipelines over Kubernetes and Marathon Mesos, and on observability with Splunk and New Relic
• Jüssi (2018 – 2021), Tech Lead and Web Developer: led the VTEX IO migration (React, Node.js, GraphQL) for major brands, keeping 99.98% uptime on Black Friday, and cut deployments from days to hours

What I use every day

• Front-end: React, Next.js, TypeScript, Vite, Tailwind CSS
• Data and state: GraphQL, BFF, TanStack Query, Zustand, Redux
