I have started my career as a web developer 10 years ago. I like challenges in which I can use modern tools and technologies to develop outstanding web applications in look, performance and efficiency. I specialise in Front-End web technologies - Vue, Nuxt, React, Next, and React Native for mobile applications. My Back-End stack includes Node.js with Express and Fastify, Firebase, Python, and PHP. For more details about technologies I know, see the expertise section below. **What I do in a nutshell** - Front-End/Back-End/Mobile - Consulting/Mentoring/Teaching - Sketching and Wireframe prototyping - UX/UI Design - Testing - Code reviews - Workshops **What I can help you with** **New project or features** Do you need a website or a mobile application? Or maybe you already have one, but you want to make it even better and include more features in it? I can build a website or a mobile application for you or help you with your current one. We can establish a short or long-term relationship, whichever suits your needs better. We can work on new features together via 1 to 1 sessions, or it can be done via job requests. **Code reviews/Consultancy** Do you or your team have a project but are not sure if you are following the best practices and patterns? Are you wondering how your code could be improved and be more efficient? Maybe you are about to start a new project but are not quite sure what technologies should you use or how to structure it for the best results. If that’s the case, then you came to the right person as I provide comprehensive code reviews with various suggestions on how you can improve your code and project. I can also advise you on how you can get started. **Bug fixes and issue-resolving** Bugs can be very annoying and hard to track and fix. Sometimes, you can waste hours pulling your hair out while trying to find out what is wrong. I can help you resolve your issues quickly and efficiently so you don’t waste any more time. **Tutoring/Teaching** Are you new in the world of development, or do you maybe want to learn new technologies and tools to advance in your existing career? I offer regular mentoring sessions which are suited to meet your needs and time schedule. We can start from the basics or work on any specific aspect of programming that is of your interest. **Anything else** If I did not mention something you need help with, we can still have a chat, so just drop me a message, and we will see what can be done. **Here are some things I did in the past** **React & Vue The Road To Enterprise books** Learn how to create blazing-fast, scalable, maintainable, and Enterprise-Ready applications with Vue and React.
