Summary of I am a Front-End Developer with back-end knowledge and over 3 years of hands-
Qualifications on experience building web applications. I have worked on educational platforms
and task-management tools, focusing on dynamic UI, user interaction, and
integration with server-side logic.

My experience includes developing web applications with dynamic content
generation, user roles, task management, and database interactions. I primarily
work with JavaScript, CSS, Node.js, SQL, and PostgreSQL, using Git for version
control.

I am familiar with Agile/Scrum practices and have participated in the full software
development lifecycle (SDLC): analyzing requirements, designing UI architecture,
coding, debugging, testing, and working with databases. My projects involved
building scalable and structured systems with dynamic template rendering and
reliable data storage.

I am particularly interested in JavaScript frameworks, full-stack development,
UI/UX improvements, and modern web technologies. I am a fast learner, motivated,
and comfortable working both independently and in a team environment. I have
strong communication skills, attention to detail, and a genuine desire to grow as a
developer.

Learning Platform
Project Description: The Learning Platform is a full-featured educational management system. The goal
of the project was to create an online environment where teachers could manage
academic activities and where students could complete tasks, submit assignments,
and access learning materials.

This platform required implementing multi-role access, a database-backed system
for storing educational content, and a dynamic interface capable of generating
pages based on user actions.
