About me
I am a Software Engineering student with a strong full-stack focus, uniting clean architecture, intentional code, and product-minded thinking with continuous attention to UI/UX for specific niches. I study usability, accessibility, information hierarchy, and interaction patterns to translate user needs into clear flows and coherent interfaces. I work with JavaScript and TypeScript across Node.js (including NestJS for modular architectures), React and Next.js for scalable experiences, plus exposure to Angular. On the front end I apply DOM best practices, accessibility, performance tuning, responsive strategy, and semantic HTML to reinforce clarity, interoperability, and perceived quality. I structure CSS with consistency and reusable design patterns.

MY APPROACH & STRATEGY
On the backend I design and implement cohesive RESTful APIs, JWT authentication, integration across PostgreSQL and MongoDB, and evolution-friendly data models. My professional identity centers on pursuing clean code, solid architecture, and sustainable software design. Principles like Clean Code, SOLID, and Object Calisthenics guide daily decisions that reduce accidental complexity and increase maintainability. Automated testing (unit and integration) strengthens reliability, prevents regressions, and accelerates safe delivery.
UI/UX and engineering move together: domain modeling, API contracts, and component semantics converge to lower cognitive friction and elevate user experience. I also explore applied machine learning for classification and recommendation when it delivers concrete value.

EXPERIENCE
internship university of anhanguera
software engineer
2025 - Present
Layered architecture (MVC) structure for REST API in Node.js, applying the Repository Pattern to isolate persistence logic, allowing switching between PostgreSQL and MongoDB without impacting business rules.
Refactoring of legacy modules using SOLID and Clean Code, reducing cyclomatic complexity by 45% and increasing test coverage from 38% to 82% with Jest and Supertest.
Implementation of a CI/CD pipeline with GitHub Actions (automated testing, ESLint lint, TypeScript type validation), reducing bugs in production by 60% and code review time from 2 hours to 30 minutes.
API technical documentation with Swagger/OpenAPI and configuration guides, reducing onboarding time for new developers from 3 days to 6 hours.
Agile task management in Kanban (weekly sprints), ensuring continuous delivery of features with traceable acceptance criteria and alignment with stakeholders.

full-stack development
2025 – present
Information architecture and interface design in React + Framer, structuring user journeys and visual hierarchy
(typography, grid, spacing) aligned with the therapeutic proposal and professional identity.
Implementation of microinteractions with GSAP and Intersection Observer, balancing visual appeal and performance through
conditional triggering of animations and lazy loading, keeping FID below 100ms.
WCAG 2.1 accessibility optimization (descriptive alt texts, keyboard navigation, visible focus, 4.5:1 contrast) and technical SEO
(HTML5 semantics, Open Graph, hierarchical headings), favoring indexing and organic reach.
Fluid responsiveness with breakpoints scaling from 320px to 1920px+ without loss of readability, and resolution of
import incompatibilities in Framer through wrapper refactoring and prop/style adjustments.

2024 – 2025
Responsive landing page development in Next.js with modular componentization (header, gallery, contact form),
reducing new feature implementation time by 40% through reusable components.
Performance optimization with lazy loading of images and code splitting, reducing Largest Contentful Paint (LCP) from 3.2s
to 0.9s and achieving a PageSpeed score of 95/100 on mobile devices.
Technical SEO implementation (dynamic meta tags, Open Graph, XML sitemap, robots.txt) and form integration with
client-side validation, resulting in Google indexing in 48 hours and a 35% +contact conversion rate.
Continuous deployment via Vercel with automatic preview per branch, accelerating the client-developer review cycle from 3 days
to the same hours and enabling iterative feedback in production.
