A passionate software engineer from the United Kingdom with a Bachelor's Degree in Computer Science. I have a strong understanding of software design and development and experience in many programming languages. I have no fear of learning a new language - be it compiled or interpreted at a low or high level. The languages I have the most experience in and the ones I find myself using most often are Python, Swift, Java, PHP and TypeScript/JavaScript. The languages I have the least experience in but have nevertheless used, Pascal, Go and Erlang. I also have experience using React, Vue, Next & Nuxt. Software Design-wise my main focus has been on MVC and HMVC and I've found little reason to venture too far from these. I also used programming paradigms such as procedural, functional and object-orientated and my aim - subject to the languages support - is always for the latter. When it comes to interface design I aim to do as much in code as possible, however, I do have experience in Photoshop and I'm more than able to create anything that is needed for a website or application's user interface. I also have a strong knowledge of the industry-standard languages for implementing the designs, those being: HTML5, CSS3 and JavaScript. My use of databases has never ventured too far from relational with the database of choice being MySql. I also have experience using Mongo DB and Elastic (for search). Outside of the office, I enjoy gaming and have a vast collection of games, spending time with my partner and daughter as well as getting together with the wider family. Anyway, I look forward to speaking with you about your project.
