I started my professional career as a software developer 15 years ago. During the course of my career, I have utilized numerous programming languages, libraries, technologies, design patterns and frameworks including: •Backend: .NET Core (ASP.NET, C#, EF Core, Identity, Performance Monitoring, Masstransit … ), API(REST, GraphQL), RabbitMQ.•Frontend: React.js, Redux, Javascript, Typescript, HTML, CSS, Tailwind, Bootstrap, Razor.•Principles: OOP, SOLID, Clean Architecture, CQRS, MVC, Dependency Injection, Security Principles, Secure Coding, Unit Test (Jest, XUnit, MSW, Moq).•Databases: MSSQL Server, DB design, SQL Query, PostgreSQL.•Tools: Git, GitHub, Azure, Jira, Vite, Fiddler, Postman.I have developed several backend solutions employing .NET Core(particularly leveraging the robust capabilities of EF Core and its strong alignment with OOP principles).I am eager to take on new challenges and I am highly capable of quickly learning new codebases. There is still a lot for me to learn, many problems to solve, and many projects to build. Considering this approach, I have challenged myself to develop two small applications utilizing Flutter, and I decided to further expand my skill set by learning React Native. Familiarity with other necessary technologies and tools such as CI/CD, Azure, IaaS helps me effectively participate in software development teams.
