    ⭐️ Worked with BMW, Nestle, VW Audi, NEC ⭐️ 100% Job Success Score ⭐️ 10+ years of experience in Web Development ⭐️ Top Rated You can expect fast decisions supported by my skills, new technologies used for particular problems, and the best solutions to implement into your project. I have been involved in web development for more than 10+ years and for me code quality and readability are my first priorities since they are very important when your project scales. Technologies: ✅ PHP, MySQL, jQuery, HTML, CSS, ReactJS, VUE.js, Solidity, Blockchain, and Web3.JS ✅ Frameworks: Laravel, Symfony ✅ Past frameworks: CodeIgniter, Kohana, and Zend Framework. ✅ CMS: WordPress, OpenCart, and others. ✅ Integrations: Stripe Payments, ChatGPT and AI, MailChimp, SendInBlue, and any API-related service. My experience focuses on web projects with a strong focus on PHP going along with evolving frameworks. I also have a great level of understanding of WordPress and have released a couple of proprietary themes. Apart from that I also have several e-commerce projects under my belt and many custom complex server-side implementations supporting mobile applications which are collaborations done with other developers for various clients. In addition, I have worked extensively with Laravel and managed to deliver significant commercial value to businesses I worked for. Check out my portfolio I am a solid problem solver and have a great commitment to promised deadlines. I would gladly collaborate with multiple developers and other functional parties like designers etc. My availability is quite flexible in terms of time zones and also depends on the current workload. Despite my overall preference for backend development I am very confident in my front-end skills and would gladly handle tasks that imply such competence. ⭐️⭐️⭐️⭐️⭐️ REVIEW: "Martin is fast yet quality-conscious, responsible, and a great initiative-taker in the best possible way. His skills stretch into many different areas: a true full-stack pro. We gave him a big challenge in terms of scale, complexity, and a whole heap of uncertainty. He tackled every problem fearlessly and with great success. Highly recommended."

    I have graduated from a mathematical high school in Velingrad. After that, I completed a Bachelor's degree in Accounting and a Master's degree in Public Finances at UNSS, but I didn't find them particularly appealing for my professional development. Instead, I enrolled in programming courses, completed the first year, and then continued to learn on my own and found a job in the field. I have one year of experience as a full-stack developer using technologies such as JS, HTML, CSS, Node.js, and MongoDB. I also have four years of experience as a frontend developer, working with technologies such as JS, jQuery, PHP, HTML, and CSS. In this role, I worked on designing pages, responsive design, PHP requests, building functionalities, and automated tests with Selenium IDE. I am interested in developing my skills in React.js and other front-end frameworks. Learning and training the whole Shopify tech stack, building themes, apps and of course both - Storefront/Admin APIs
