Experience

I lead core frontend platform initiatives that enable multiple teams to ship faster with consistency, scalability, and security.

What I’m building and have delivered:

• Responsible for the frontend architecture, bringing best practices of sofware engineering and cyber security,

• Frontend Chapter (Chapter Leader): founded and lead the company’s first Frontend Chapter, driving standards, technical direction, mentorship, and cross-team alignment.

• Design System (Creator & Maintainer): created and maintain a scalable design system to ensure UI consistency, accessibility, and faster product delivery.

• Frontend SDK (Creator & Maintainer): built and maintain shared SDKs to standardize integrations, reduce duplication, and improve developer experience.

• Microfrontend Platform: designed and implemented a multi-app architecture with 5 applications and a clear path to scale further using Next.js Multi-Zones on Vercel.

• Centralized Authentication: delivered a secure auth architecture using OAuth 2.0 + PKCE, with server-side cookie handling, supporting 9,500+ users.

• Environment Strategy: implemented separate dev/prod configurations for reliable builds and deployments across environments.

• CI/CD: set up and evolved pipelines with GitHub Actions to automate quality checks, builds, and releases.

• AI & Developer Enablement: actively spread AI knowledge and promote AI-assisted development practices across the company to boost productivity and quality.

Casas Bahia

I led the co-branded web platform for Casas Bahia (Via Varejo), rolling out a white-label solution used by Casas Bahia, Extra, and Ponto Frio. I focused on a scalable architecture, per-brand theming, and clean release flows so each retailer could ship fast without forking the codebase keeping performance, accessibility, and security as baselines.

• Designed a white-label architecture with brand tokens, theme switches, and shared components

• Centralized config/feature flags for per-brand behavior without branching the repo

• Set performance/A11y guardrails and monitoring to keep experiences fast and consistent

• Streamlined CI/CD and release strategy for multi-brand deployments

• Partnered with product/design to align requirements and reduce duplicate work

Gipsyy

I led the front-end development of Gipsyy’s self-service Totem at FCamara, focusing on performance, DX, and a smooth user flow. The app was built with Next.js and Tailwind; React Query handled data fetching/caching; and Vitest provided unit test coverage for confidence in each release.

• Shipped a high-performance UI with clear component patterns

• Implemented data fetching with React Query (caching, retries, background updates)

• Added unit tests with Vitest to prevent regressions and speed up reviews

• Documented architecture and setup to make onboarding faster for new devs

On the Design System team at Fretebras, I built reusable Web Components with Stencil and helped publish our libraries to a private npm registry. I partnered closely with design to keep visual fidelity high, ensured strong typing and DX for consumers, and focused on performance, accessibility, and maintainability.

• Authored and maintained Stencil-based Web Components with clear APIs and docs

• Drove versioning, changelogs, and release automation for private npm packages

• Established contribution guidelines, testing, and CI checks to keep quality consistent

• Worked with product teams to adopt the DS and deprecate duplicate UI code

• Monitored usage and stability with Grafana/Prometheus; improved build times and bundle size where needed

At Fretebras, I built front-end features for a marketplace (micro-frontends with Module Federation), a back-office suite, and an internet banking site. I worked across design, engineering, and QA to ship responsive, accessible interfaces with solid performance and security. My work covered everything from UI architecture and state management to API integration, testing, and CI/CD.

• Micro-frontend modules that integrated cleanly with shared design system and routing

• Resilient data flows with Axios and typed REST contracts, plus loading/error states that actually help users

• Test coverage with Jest to prevent regressions and speed up reviews

• CI/CD improvements on GitLab CI; containerized services with Docker and Kubernetes

• Observability via Grafana/Prometheus to catch issues early and track SLIs

As a Software Consultant at Opah IT Consulting, I delivered custom software for banking clients across web and mobile. I worked hands-on with React.js and React Native, shaped requirements with stakeholders, and partnered with cross-functional teams to integrate features securely and on schedule. The focus was always clear: build what the business needs, keep performance high, and ship with confidence.

• Scoped and delivered features end-to-end (requirements → implementation → rollout)

• Built shared UI components and patterns for consistency and speed

• Collaborated on secure integrations and performance tuning for high-traffic flows

• Supported release processes with documentation, code reviews, and test coverage

I built and maintained a white-label e-commerce platform used by multiple clients, tailoring features to each brand while keeping a single, secure codebase. I designed and delivered custom solutions per client requirements, and made sure performance, reliability, and security standards were consistently met.

• Designed and shipped client-specific features without fragmenting the core platform

• Improved performance and reliability while meeting strict security guidelines

• Partnered with stakeholders to capture requirements and deliver on schedule

• Wrote clear documentation and handoff notes to streamline future rollouts
