I specialize in JavaScript frameworks, especially React, and I work confidently with TypeScript, HTML5, CSS3, and modern state management patterns. I have strong experience integrating REST APIs and SOAP services, collaborating closely with backend developers and cross-functional teams to deliver complete features. I focus on performance optimization, maintainable architecture, and user experience, and I have contributed to measurable improvements in page load times and system stability. I have also worked in Agile/Scrum environments and participated in code reviews, testing, and iterative product development. I am open to opportunities where I can continue growing as a frontend specialist and contribute to scalable web products. ## Skills ### [JavaScript](https://jobicy.com/talent/javascript.md)[Java](https://jobicy.com/talent/java.md)[React](https://jobicy.com/talent/react.md)[TypeScript](https://jobicy.com/talent/typescript.md)[Git](https://jobicy.com/talent/git.md)[Agile](https://jobicy.com/talent/agile.md)[MySQL](https://jobicy.com/talent/mysql.md)[Scrum](https://jobicy.com/talent/scrum.md)[PHP](https://jobicy.com/talent/php.md)[Performance Optimization](https://jobicy.com/talent/performance-optimization.md)[SQL Server](https://jobicy.com/talent/sql-server.md)[HTML5](https://jobicy.com/talent/html5.md)[Redux](https://jobicy.com/talent/redux.md)[Jest](https://jobicy.com/talent/jest.md)[Accessibility](https://jobicy.com/talent/accessibility.md)[Responsive Design](https://jobicy.com/talent/responsive-design.md)[CSS3](https://jobicy.com/talent/css3.md)[jQuery](https://jobicy.com/talent/jquery.md)[UX UI Design](https://jobicy.com/talent/ux-ui-design.md)[Laravel](https://jobicy.com/talent/laravel.md)[Bootstrap](https://jobicy.com/talent/bootstrap.md)[Symfony](https://jobicy.com/talent/symfony.md)[React Testing Library](https://jobicy.com/talent/react-testing-library.md)[Zustand](https://jobicy.com/talent/zustand.md)[React Query](https://jobicy.com/talent/react-query.md)[Material Design](https://jobicy.com/talent/material-design.md)[CSS Modules](https://jobicy.com/talent/css-modules.md)[CakePHP](https://jobicy.com/talent/cakephp.md)[SWR](https://jobicy.com/talent/swr.md) ## Tech Stack & Tools ### Application Hosting [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/nginx/nginx-original.svg) Nginx](https://jobicy.com/talent?tool=nginx.md) ### Collaboration [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/jira/jira-original.svg) Jira](https://jobicy.com/talent?tool=jira.md) ### Data Stores [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/mysql/mysql-original.svg) MySQL](https://jobicy.com/talent?tool=mysql.md) ### Development [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/git/git-original.svg) Git](https://jobicy.com/talent?tool=git.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/github/github-original.svg) GitHub](https://jobicy.com/talent?tool=github.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/jest/jest-original.svg) Jest](https://jobicy.com/talent?tool=jest.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/ssh/ssh-original.svg) SSH](https://jobicy.com/talent?tool=ssh.md) ### Languages & Frameworks [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/bootstrap/bootstrap-original.svg) Bootstrap](https://jobicy.com/talent?tool=bootstrap.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/cakephp/cakephp-original.svg) CakePHP](https://jobicy.com/talent?tool=cakephp.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/laravel/laravel-original.svg) Laravel](https://jobicy.com/talent?tool=laravel.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/react/react-original.svg) React](https://jobicy.com/talent?tool=react.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/symfony/symfony-original.svg) Symfony](https://jobicy.com/talent?tool=symfony.md) ### Libraries [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/jquery/jquery-original.svg) jQuery](https://jobicy.com/talent?tool=jquery.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/redux/redux-original.svg) Redux](https://jobicy.com/talent?tool=redux.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/zustand/zustand-original.svg) Zustand](https://jobicy.com/talent?tool=zustand.md) ## Experience Frontend Developer @ BMDatos Oct 2023 - Present Develop responsive web applications for mobile, tablet, and desktop platforms using JavaScript and modern frontend frameworks.
