My tools


HTML is the foundation of a good website. I make use of HTML semantics to improve screen-reader accessibility and SEO. I always make sure my markup is W3C validated.


I use SASS for my CSS. I aim for well-organized non-repetitive stylesheets. I use Bootstrap, as the starting point for my designs and take it from there with custom modifications.


JS is a language of many quirks, my knowledge in lower-level languages has helped me comprehend its mechanics. I employ ReactJS and Redux, with a functional approach, to deliver demanding frontend solutions.
