    1. Advanced R Shiny Apps 2. Javascript, CSS & HTML, integrating with R shiny apps 3. R Markdown/ flexdashboard reports, automation 4. R Packages 5. HTMLWidgets with R 6. Website/ blog with R ** No Assignments/ tests/ homework please, owing to Ethical Issues. I enjoy working with the aforementioned topics, but my domain isn't confined to them only. Basically, anything related to R programming and I am up for it! A statistician turned developer and an R lover, that would be me! By the dint of Allah the Almighty, I have been coding in R for ~5 years now and have learnt some tricks, still a long way to go though! Ever since my introduction to R, Shiny & the wonderful community, I never looked back. I may have worked with Python for about a year, but I call myself a full time R developer now. Being a Statistician, I used to analyse data, find hidden insights and present it to the mass people using reports and workbooks. Now I do almost the same thing, only with Dashboards and Web Applications, and of course, with R! Alhamdulillah, I have a website which is focused mainly on R. If one has the time, I'd say please pay a visit. (The link should be somewhere in the profile, I'm not sure where!) A tiny achievement, An Honorary Mention in the Shiny-Contest-2020, hosted by RStudio, for an app titled 'Life of Pi'. One may find it in the portfolios section. That's pretty much it. Do connect if you feel like it. Zauad
