‼️ALERT‼️ Description written by a human! Already shocked? There's more! 😱 I have been in development since 2012. Worked with many clients on different jobs. Created many pages for websites and apps. Learned so many tools and technologies over the years that some of them are already forgotten and replaced by newer, better solutions. But still learn something new every week. There is always something new to try! Collaborated with dozens of teams of different sizes. But most often, I work independently, directly with the Product Owners/CEO, handling every part of the development process. Created websites in marketing, advertising, real estate, adult, vehicle, motorcycle, cruise, e-commerce, travel, healthcare, education, finance, technology, food delivery, sports, fitness, and many, many other areas. I take full responsibility for my work and ensure clients do not face any technical problems or stress. If a new tool is required, I am eager to learn it quickly, or I will seek expert assistance so the job gets done quickly. My priority is always to deliver top-notch outcomes for clients, no matter the challenge. I actively use AI in my work and see it as one of the most powerful tools for a modern developer. I know which AI works best for different tasks and use Claude Code every day for coding and reviewing. Claude Code is my daily assistant for generating, reviewing, and optimizing code. I understand how to set tasks for AI, have developed my own guidelines, and follow a personal workflow to achieve reliable and high-quality results. I always review the code manually to make sure it meets the standards. With vibe code, I have fully developed dozens of projects and brought them to production. They work successfully in real environments. No matter what, the client is always informed about the development process. They can choose between a fully vibe code workflow, a hybrid method, or a greater emphasis on human-written code. Feel free to contact me!
