Why me

Determined & Driven
Tough coding challenges motivate me—like building my JavaScript game “El Pollo Loco”. Giving up isn't my style; I'll debug until 2am if that's what it takes.

Creative & Detail-oriented
Designing pixel-perfect layouts isn’t just work—it’s my passion. From Angular apps to WordPress redesigns, details matter until they're exactly right.

Thriving Under Pressure
Deadlines sharpen my focus. When our Firebase project hit tricky Git conflicts, I didn't panic—I adapted quickly. Honestly, pressure brings out my best.
My Skills











Up next: React and Vue.


React and Vue are next on my learning journey—planned once I finish my current projects. Staying curious and growing my skills keeps me sharp and motivated for future frontend challenges.
My Projects

2. El Pollo Loco

4. Ongoing Project

About the project
Join is a Kanban-inspired task manager for web and mobile, featuring task creation, drag-and-drop organization, guest access, and user registration. Data is managed via Firebase.

How I have organised my work
I focused on modular, reusable code and clear naming conventions. Ensuring responsive design from the start was a key priority.

My group work experience
In a team of four developers, I built the Add Task feature—including form handling, validation, and Firebase integration. We collaborated remotely via Git and launched the project after four weeks.
