I am a Full-Stack Developer who creates web applications, Telegram bots, Telegram Mini Apps, admin panels, CRM systems, and business automation tools.

I help turn an idea or business process into a working digital product: from a simple MVP to a complete system with a database, authentication, an admin panel, API, and deployment.

I work with the following areas:

• Telegram bots and Mini Apps — business bots, requests, payments, user accounts, integrations, and process automation.
• Web / SaaS / CRM — admin panels, dashboards, accounting systems, user dashboards, and internal business tools.
• Backend and API — Python, FastAPI, databases, and integrations with third-party services.
• Automation — requests, notifications, spreadsheets, CRM logic, and business processes that can be simplified with code.
• Deployment and project structure — I can help not only with writing code, but also with preparing the project for launch.

For me, it is important not just to “write code”, but to create a solution that is actually convenient to use. Before starting, I clarify the task, suggest the best workflow logic, explain complex things in simple words, and keep the project structure clear and organized.

I can help you if you need to:

— create a Telegram bot or Mini App;
— build an MVP for a business idea;
— develop an admin panel or CRM system;
— connect a database, API, or authentication;
— improve or fix an existing project;
— automate routine business processes.

I work carefully and responsibly, and I always try to build projects in a way that makes them easy to support and improve in the future.
