Kevin Matamoros

Senior Front-End Engineer with 5+ years of experience building scalable, high-performance web applications using React, Angular, and Vue.js. Proven track record implementing components from visual design to production markup, writing unit and behavior-driven tests (TDD/BDD with Jest, Karma, Cucumber), and conducting thorough code and pull request reviews that elevate team quality standards. Deep understanding of web fundamentals — HTTP protocols, browser rendering lifecycle, cross-browser compatibility, and responsive design — combined with a strong accessibility mindset (WCAG).

Experienced working within enterprise Agile environments, collaborating closely with UX teams, consuming acceptance criteria to design component behavior, and communicating proactively with project leads. AWS and Azure cloud exposure; committed to clean, maintainable code and continuous team improvement.

Software Developer at Infoya (2022-09 – Present)

Led front-end development and quality practices for scalable web applications, owning component architecture, test coverage, and code review processes in an enterprise Agile environment.

• Developed and maintained production-ready UI components using Angular, React, and Vue.js with TypeScript, translating visual designs — including fonts, animations, and transitions — into pixel-perfect, responsive markup.
• Adopted TDD practices writing unit and integration tests with Jest and Karma, and BDD scenarios with Cucumber, ensuring behavior matched acceptance criteria before delivery.
• Conducted code and pull request reviews, providing actionable feedback to junior engineers on code standards, design patterns, and maintainability — raising overall team quality and reducing regression.
• Optimized front-end performance across network, render, and component lifecycle dimensions; implemented lazy loading, code splitting, and caching strategies to improve Core Web Vitals.
• Integrated REST APIs and applied web standards (HTTP/S, CORS, TLS) to deliver secure, consistent data flows between front-end and back-end services.
• Built performant, accessible UI features using React and Angular, following established design patterns and enterprise architecture guidelines across a multi-team codebase.
• Collaborated directly with UX designers to translate mockups and interaction specs into fully functional components across all viewport sizes, incorporating animations and transitions accurately.
• Demonstrated WCAG accessibility knowledge — ARIA roles, keyboard navigation, contrast — ensuring inclusive user experiences across all delivered features.
• Participated in story definition sessions, providing front-end technical recommendations on acceptance criteria and flagging potential implementation issues early to project leads.
• Performed manual and automated testing across browsers and devices, applying root cause analysis to resolve compatibility issues and prevent recurrence.

Front-End Developer at Eleven Systems, LLC (2018-07 – 2021-07)

Owned front-end implementation for client-facing web applications in a fully remote Agile team, building from design to production across a range of browsers and devices.

• Built responsive, cross-browser-compatible web features using JavaScript (ES6+), HTML5, and CSS3, faithfully implementing visual designs including layout, typography, animations, and interactive states.
• Applied web standards and networking fundamentals (HTTP, REST, TLS) when integrating APIs, ensuring correct data handling and consistent behavior under real-world conditions.
• Maintained version control workflows with Git, participating in collaborative branching, code reviews, and release management within a distributed team.
• Designed test cases for functional, regression, and integration scenarios aligned to acceptance criteria, building the BDD and TDD perspective carried into all subsequent development roles.
• Performed root cause analysis on defects, collaborating with engineers to resolve issues and prevent recurrence — directly shaping the code review and quality practices I apply today.

Quality Assurance Analyst at Business Solutions (2017-04 – 2018-07)
