What I'm looking for

I seek front-end or full-stack roles where I can build accessible, responsive interfaces, collaborate in agile teams, continue learning modern web technologies, and contribute technical support experience to improve product quality.

I am a front-end developer with strong practical experience building Frontend Developer with experience building and maintaining production web applications using React, TypeScript, and modern JavaScript. I focus on creating clean, maintainable user interfaces that consume APIs, handle real-world state, and scale beyond simple demo projects.

I’ve worked on full-featured web systems that include authentication flows, data-driven dashboards, and admin-style interfaces, collaborating with backend services built with FastAPI / Node.js and relational databases. My work emphasizes component-driven architecture, clear separation of concerns, and readable code.

I have hands-on experience integrating APIs, managing client-side state, implementing routing, handling loading and error states, and translating UI requirements into functional features. I’m comfortable working independently, debugging issues, and improving existing codebases.

Before focusing full-time on web development, I spent several years in technical support, QA, training, and customer-facing roles for U.S.-based companies, which strengthened my communication skills, problem-solving mindset, and ability to work effectively in distributed, remote teams.

I’m currently focused on growing as a frontend engineer, deepening my React and TypeScript expertise, and contributing to teams where code quality, collaboration, and learning are valued.
