Project details

I will build, fix, complete, or deploy a small-to-medium website or web application based on a clearly defined scope.

This service can include responsive pages, interface improvements, bug fixes, unfinished code, forms, authentication, API or database integration, small features, and deployment. I work with modern technologies including React, TypeScript, JavaScript, HTML and CSS, Java, Spring Boot, MySQL, Firebase, and related development tools.

Before starting, I review your requirements and existing code, confirm exactly what is included in the selected package, and identify any files or access needed. You will receive direct communication, progress updates, tested work, and the complete source code for the delivered task.

The Starter package covers one small fix. Standard covers up to two small related fixes or one simple responsive page. Advanced covers one clearly defined small feature or up to three basic pages.

Large platforms, major redesigns, complex migrations, and extensive new functionality require a separate custom offer.

Need a web application, REST API, mobile app, bug fix, or reliable software testing? I can help you turn the task into a working, tested, and documented solution.

I am a full-stack software developer with practical experience in backend, frontend, mobile development, API integration, databases, automated testing, and application troubleshooting.

My main areas of work:

• Web application development with React and TypeScript
• Backend development with Java and Spring Boot
• REST API development, integration, and documentation
• MySQL database design and application integration
• Mobile development with Flutter, Dart, Kotlin, and Jetpack Compose
• Firebase Authentication and Cloud Firestore integration
• Manual and automated software testing
• API testing with Postman, Swagger, JUnit, and RestAssured
• Bug investigation, reproduction, fixing, and verification
• Docker-based local environments and application setup
• Technical documentation and project configuration

Selected projects:

Book Exchange — a full-stack platform built with Java, Spring Boot, React, TypeScript, MySQL, Docker, and REST APIs. It includes authentication, role-based access, book ownership workflows, an administrator panel, database migrations, OpenAPI documentation, 77 backend tests, and 30 independent API tests.

CarNation — a Flutter and Firebase vehicle marketplace with authentication, vehicle search and comparison, saved items, Firestore request management, real-time status updates, security rules, and 64 automated tests.

Kvantor — an Android learning application built with Kotlin, Jetpack Compose, Firebase, Firestore, progress tracking, gamification, and an AI-assisted learning feature.

I can work on both small and larger tasks, including fixing one API endpoint, connecting a frontend to a backend, adding a new feature, testing an existing application, improving database logic, configuring a project locally, or developing a complete application module.

What you can expect:

• Clear and regular communication
• Honest estimates and progress updates
• Clean, understandable, and maintainable code
• Careful testing before delivery
• Documentation and setup instructions
• Attention to requirements and edge cases

Technologies: Java, Spring Boot, Spring Security, Spring Data JPA, Hibernate, REST APIs, MySQL, React, TypeScript, Flutter, Dart, Kotlin, Jetpack Compose, Firebase, Docker, Maven, Git, GitHub, JUnit, RestAssured, Postman, Swagger, and OpenAPI.

I am ready to help with web development, backend services, mobile applications, API integrations, testing, bug fixing, and technical support.
