What I'm looking for

I seek roles where I can lead frontend and mobile development, improve performance and accessibility, work in agile teams, and drive scalable architecture.

I am a Software Engineer with over 4 years of experience building modern, scalable, high-performance web and mobile applications. I prioritize best practices, clean well-structured code, and performance optimization.

In corporate and mission-critical environments, I have delivered using agile methodologies, automated testing, and CI/CD to ensure reliable continuous delivery. I have hands-on experience across frontend and backend stacks and database optimization.

Recently I have served as a technical lead for web (Next.js 15) and mobile (React Native) development, implementing global state management with Zustand and TanStack Query, and establishing UI/UX standards using Tailwind CSS and shadcn/ui.

I have also worked on enterprise applications with OutSystems, modernized legacy ERP systems with C#/.NET, and improved database performance through SQL optimization. I bring a pragmatic focus on accessibility, performance, and maintainable component-driven development.
