Senior Full-Stack Developer with over 15 years of industry experience. I’ve worked across different tech stacks, combining various technologies, languages, and frameworks. I hold a Microsoft certification (JavaScript, HTML5 & CSS3) and will be getting my AWS certification next year (2027). I truly believe that people are the most important part of a project. Because of that, a healthy environment, mutual respect, and common sense are highly valuable to me. Right now, I’m focused on building projects with the help of AI, understanding the world around big data and data engineering, and diving deep into getting my next certification (AWS).
