Danylo Lysiuk

Full-stack Developer | Telegram Bots, Websites, APIs, Backend

My name is Danylo. I work with both frontend and backend, so I can handle a project as a complete solution: from database structure and server-side logic to the user interface.

What I can do:

• Telegram bots for business, requests, notifications, automation, and data processing;
• bots with admin panels, user roles, databases, and integrations;
• landing pages, corporate websites, catalogs, and web applications;
• backend development with ASP.NET Core;
• REST APIs for websites, mobile applications, and internal services;
• databases, SQL queries, PostgreSQL / SQL Server;
• personal accounts, admin panels, and CRM-like systems;
• integrations with CRM systems, Google Sheets, payment systems, and third-party services;
• improvement, bug fixing, and maintenance of existing projects.

Technologies I work with:

C#, ASP.NET Core, Entity Framework Core, SQL, PostgreSQL, JavaScript, TypeScript, React, HTML, CSS, Python, REST API, Git.

How I work:

First, I clarify the task and business logic, then I suggest a clear solution structure. After that, I implement the project, test the main scenarios, and explain how to use the final result. For me, it is important not just to “write code”, but to build a working solution that actually solves the client’s problem.
