I am a Junior Frontend Developer with no commercial experience, currently studying at an IT school (approximately 1 year of hands-on practice). During this time, I have gained experience in building web applications, working with APIs, creating responsive layouts, and implementing basic business logic.
I have worked on real educational and pet projects, including SPA development, form handling, state management, routing, third-party API integration, and project deployment. I actively use Git and GitHub in my development workflow.
1. Eco Shop
Adaptive landing page for an eco-friendly store with a focus on product presentation and modern UI.
Developed the “Our Bags” section: built the HTML structure and styling, ensured responsiveness across different screen sizes. Worked with design mockups and followed UI/UX principles.
Also acted as a Scrum Master: organized team workflow, coordinated tasks, and monitored deadlines and communication.
Technologies:
HTML, CSS (Flexbox, Grid), Git, Figma, Vite
2. Book Shop
Web application for a bookstore with interactive elements and dynamic content.
Implemented the “Events” section: developed dynamic logic using JavaScript, worked with the DOM (rendering lists, handling user interactions).
Acted as a Team Lead: coordinated the team, distributed tasks, supported technical decisions, and ensured code quality.
Technologies:
JavaScript, HTML, CSS, Git, Vite, Figma
3. NoteHub
SPA application for creating and managing notes with the ability to add, edit, and delete entries.
Independently developed the entire project: implemented component-based architecture, note management logic, state handling, event processing, and list rendering. Ensured a user-friendly UI and clear application structure.
Technologies:
React, JavaScript, HTML, CSS, Git

Looking for
I am looking for a Junior Frontend Developer position where I can grow my practical skills, work on real-world products, and gain commercial development experience.I would like to work in a team with established development processes, receive feedback from more experienced developers, and improve my knowledge of modern frontend technologies, especially React and JavaScript.
I value a supportive environment, clear communication, and opportunities for professional growth.
I would prefer to avoid roles with no mentorship or feedback, unclear task requirements, or lack of structured development processes.
I am also not interested in positions that involve only repetitive, non-development tasks without opportunities to learn and grow as a developer.

MAIN ACHIEVEMENTS ON THE LAST PROJECT:* Extended existing test suites with negative test scenarios that helped to detect critical bugs and increase revenue;

* Initiated data events testing that helped to improve the quality and relevance of gathered data;
* Successfully delivered checkout functionality for a new brand (including the following payment methods: PayPal, AmazonPay, ApplePay, Google Pay, Affirm, Stripe
HOW DO I IMPROVE OR BUILD THE TESTING PROCESS:
The three main principles that help me to integrate quality into the development process are Shift Left testing (start testing activities as early as possible), Exploratory testing (powerful testing approach that helps to enhance testing efforts and reveal tricky bugs in shorter period of time), Test Analysis (choosing the right test design technique is the key factor in testing)
Also I like creating detailed HOW TO guides when team mates are asking the same question too many times. I encourage peer review at every stage of STLC. I love combining different test design techniques in order to optimize the testing efforts and reveal more bugs within shorter period of time. Make sure that proper QA processes are established and being followed. Working on bug prevention and building confidence in the product.
