CV
My name is Mark, I'm 19 years old, and I'm a web developer and Telegram bot specialist with over three years of experience. I founded my own studio, where I've assembled a team of professional designers and programmers—specialists with experience equal to mine, and sometimes even greater.
Our studio is ready to help clients create websites, web applications, and automated services from start to finish. We implement any project: from landing pages and online stores to CRM systems and custom solutions.
We work with modern technologies, API integrations, and databases, and each project is completed with a customized approach, taking into account business goals and user needs.
Currently based in Warsaw, Poland, I'm ready to collaborate with clients worldwide, providing high-quality, reliable, and effective digital solutions.
Our strengths:
A team of professionals: designers, editors, programmers, and full-stack developers.
Over three years of experience creating Telegram bots and web projects.
Full development cycle: from concept to finished product.
A personalized approach to each client.
Modern technologies and integrations with APIs and databases.
We create projects that work, deliver results, and leave an impression.
