Hello! My name is Mladen, I'm a self-taught frontend web developer from Serbia. I am a PC and tech enthusiast with a passion for development and website creation. I will build your website from the ground up, using the latest technologies and best practices with a strong attention to detail. MY TECH STACK My primary skill and focus is NextJS, one of the most popular frameworks for modern web development, which allows me to build good-looking and best-performing web apps. Besides Next, this is my entire tech stack that I'm constantly trying to improve: HTML5 / CSS3 / SASS / TailwindCSS / Javascript / ReactJS / Typescript / Redux / MongoDB / Firebase / Git / Figma / Framer Motion KEY SKILLS: ✔️ Frontend Web Development - I will build your website from scratch ensuring the pixel-perfect design. ✔️ Responsive Design - My strong understanding of visual design principles will ensure that your website will always be responsive and will look amazing no matter the screen size. ✔️ Crazy attention to detail - I'm not satisfied if my work is not PERFECT! This may seem like an exaggeration, but if I notice even a tiny, apparently unimportant detail, I can't let it go, I must fix it. ✔️ Building full websites - Hand-coding all of my projects from start to finish, using all of the latest technologies, ensuring eye-catching end results and a clean code base. ✔️Not static, but dynamic! - I will not only build dull, boring visuals and throw them to you, but I will do my best to make even the simplest elements come to life. ✔️ Respecting you and your time - Maybe not a "skill" at first look, but not showing up to an agreed call, not answering messages, or not doing 100% to fulfill all of your requirements, is simply not an option for me. Ready to take your digital presence to the next level? Let's work together! 😉
