Backend Web Developer

What I can do

I am a web developer with a focus on building clean, functional websites and continually broadening my technical skill set. I work confidently with HTML and CSS, and I am steadily developing my expertise in JavaScript, jQuery and Photoshop. I take genuine pride in the work I produce. At House of Kaizen, where I began as an apprentice, I specialise in conversion rate optimisation (CRO) and have grown considerably as a developer.

My profile

I am currently an apprentice at a company specialising in web development, ecommerce and conversion rate optimisation, where I have gained a strong foundation in IT and computing. I am proficient in HTML and CSS, with practical experience in JavaScript and jQuery, and I am also confident across Microsoft Excel, Word, PowerPoint and Outlook. Organised and dependable, my goal is to build a career in the technology sector as a programmer or front-end developer.

Interest

Arsenal

I am a lifelong Arsenal supporter and have enjoyed both playing and watching football for as long as I can remember. It is a passion that has taught me the value of teamwork and commitment.

Art

I developed a passion for art in the later years of school, where I discovered a love of drawing. I am particularly drawn to the range of tones achievable with a single colour, an appreciation that directly inspired this website's palette of greys. One of my most rewarding projects was influenced by the work of Max Ernst.

Travel & Photography

I also enjoy travelling and unwinding by the sea. Photography is another interest of mine, and I like experimenting with filters and editing to create striking, dramatic effects.
