🚀 Full-Stack Developer | React • TypeScript • Next.js • ASP.NET • PHP
I help businesses, startups, and individual clients build modern web applications - from intuitive user interfaces to backend development and project deployment. My focus is on delivering fast, scalable, maintainable solutions with strong attention to performance, user experience, and code quality.
💻 Core Stack:
• Frontend: React, Next.js, TypeScript, JavaScript, HTML, CSS, SCSS
• Backend: ASP.NET Core, C#, PHP, REST API
• Databases: MySQL, MS SQL Server, Redis
• Infrastructure: Docker, Docker Compose, Nginx, Git, GitHub Actions
• Additional: SSR, SEO, CI/CD, third-party integrations, business process automation
Over the past few years, I have worked on both commercial and personal projects related to web development, process automation, and client-server applications.
My specialization is building interfaces that not only look great but are also fast, user-friendly, and easy to maintain. During development, I pay close attention to application architecture, component reusability, and long-term scalability.
I also work with backend systems, including REST API design and development, database integration, authentication and authorization, business logic implementation, and third-party service integrations.
In addition to customer-facing applications, I have experience developing internal tools and services for developer productivity, data analysis, and information processing. I have worked on projects involving CI/CD pipelines, application containerization, server infrastructure setup, and automated deployments.
When required, I can handle the entire development lifecycle - from requirements analysis and architecture design to deployment and long-term maintenance.
What I can help you build:
✅ Web applications from scratch
✅ React / Next.js frontends
✅ Full-Stack solutions
✅ REST API design and development
✅ Third-party service integrations
✅ Responsive websites from Figma designs
✅ Admin panels and internal business systems
✅ Business process automation
✅ Performance optimization and SEO
✅ Docker-based deployments
✅ CI/CD pipeline setup
✅ Support and further development of existing projects
I value clean, maintainable code, reliable communication, and meeting project deadlines. If you are looking for a developer who can take your idea from concept to production, I would be happy to work with you.

FileSystemManager
C & C++FileSystemManager - a console file manager with a multi-user access system, developed in C++17 without using third-party libraries.
The project allows creating isolated user workspaces, managing files and directories through the command line, performing searches, navigation, and operations with the file system in a secure environment.
… What has been implemented:
#CPlusPlus #CPP17 #STL #FileSystem #CLI #ConsoleApplication #SoftwareEngineering #Backend
- user registration and authentication;
- storage of accounts with password hashing and salt;
- isolation of users in their own working directories;
- protection against going beyond the workspace (Sandbox);
- creation, deletion, renaming of files and directories;
- navigation through the file system via console commands;
- viewing and modifying file contents;
- searching for files by mask;
- calculating sizes of files and directories;
- history of entered commands;
- command autocompletion via Tab;
- object-oriented architecture in C++17;
- automatic build and testing via GitHub Actions.
The project demonstrates skills in system software development, working with the file system, application architecture design, implementing user authentication, ensuring data access security, and creating complex console interfaces without external dependencies.
The solution can be used as an educational file shell, a basis for corporate file management tools, or a platform for further development towards a client-server file manager.

CommitScope
PythonCommitScope - a tool for analyzing GitHub repositories and development history.
The project allows obtaining commits, diff patches, file changes, comments, and statistics from GitHub through a convenient web interface, API, and console application.
… What has been implemented:
#Python #FastAPI #GitHubAPI #Docker #RESTAPI #CLI #WebDevelopment #Automation
- integration with GitHub API;
- obtaining commit history by repository and branch;
- filtering by authors;
- analysis of changed files and diff patches;
- generation of JSON reports;
- REST API for integration with external services;
- console interface for task automation;
- web interface for viewing results;
- Docker containerization of the project;
- working with public and private repositories via access token.
The project demonstrates working with external APIs, processing large volumes of data, designing REST APIs, creating CLI tools, containerization, and automating development processes.
The solution can be used for code auditing, analyzing developer contributions, preparing project reports, and integrating with internal tools of development teams.

Web ProgrammingDeveloped a SPA for order delivery processing using React and TypeScript.
The project allows the user to build a route with multiple points, specify cargo parameters, select a date, fill in contact details, and receive an automatic real-time cost estimate for delivery.
… Implemented features:
#HTML/CSS/JavaScript/jQuery #html/css/js #React #TypeScript #Vite #SCSS #SPA #Frontend #API #AdaptiveDesign
- dynamic addition and removal of route points;
- distance calculation via OpenRouteService API;
- automatic recalculation of order cost;
- validation of email, phone, date, and time;
- saving form data after page reload;
- light and dark themes;
- responsive layout for desktop, tablet, and mobile;
- deployment on Vercel;
- CI through GitHub Actions.
This project demonstrates working with a complex form, external API, application state, responsive interface, and business logic for cost calculation.
