About Lais
Full-Stack Developer specialized in scalable and user-centric applications, with a stack featuring React 19 + TypeScript (frontend) and Ruby on Rails / Node.js (backend).
I have developed solutions such as:
PaLeva (restaurant management platform built with Rails 7.2 + React/TS): full order lifecycle management, WebSockets for real-time notifications, analytical dashboard — reduced order processing time by 30%.
Brazilian Cinema (React/TS app with Firebase Auth, TMDb API integration, advanced filters, and infinite scroll).
Technical Skills: RESTful APIs, PostgreSQL/MongoDB, Docker/Compose, AWS (EC2/S3), TDD (Jest/Vitest/RSpec), CI/CD (Vercel/Render), Agile/Scrum, Microservices, Performance Optimization (lazy loading, caching).
My background in sales (10+ years: consistently exceeded targets by 20% annually, honing UX focus and performance under pressure/deadlines) and teaching (1 year: increased student engagement by 40% through educational tech) strengthens my soft skills — clear communication of complex concepts, rapid adaptation, and strong collaboration in agile teams — making me well-suited for quick onboarding and effective stakeholder management.
I am seeking opportunities in SaaS, HRTech, or operations companies in Barcelona / Europe (hybrid or remote preferred), where I can deliver clean, sustainable, and high-impact code.
