I also create a lot of custom event websites using Swoogo. I do this with my broad set of skills; including design and development (PHP/JS/CSS/Sass), UX, SEO, website performance, digital marketing, and more! My range of skills are vast, so just get in contact—I'm usually able to help with most web or tech situations—and always happy to chat. guwii.com is my personal brand - a complete solution for businesses, offering web design, development, SEO, digital marketing and more. I have created over 500 websites, including unique market-leading websites. Web and technology is a hobby of mine as well as a profession, so when I'm not working on client or professional sites, I'm likely playing with some new technology.

    I am a student studying Software Engineering at a Russel Group university, my passion for computer science and programming is extremely fervent and I hope to study a postgraduate Computer Science masters degree once I have completed my undergraduate degree in which I am currently achieving first-class honours. In the field of Computer Science, I am most interested in algorithms, how and why we use algorithms like Dijkstra's algorithm, and how algorithms can be improved to produce a lower time complexity and the most efficient code possible. For my degree and to enhance my learning experience, I have made many programs using Python, Java, and Javascript - including web applications using the Spring framework for Java and Flask framework for Python. Another critical interest of mine lies in optimisation of algorithms and applications and have completed assessments relating to designing, benchmarking and optimising algorithms, and load-testing a website and identifying and optimising bottlenecks. Although I am generally attracted to quantitative study, I took A-Level English, in which I achieved an A grade, and I love reading literature and writing when I have the time. I would also like to offer my services in writing scintillating articles and rewriting content for non-native English speakers. I am also very attentive and meticulous, so I would make an excellent proofreader and can focus on reading for hours on end. This, combined with my knowledge of grammar, punctuation, and spelling, would make me an excellent proofreader.
