As a Blockchain Enthusiast my passion towards learning Haskell started 2 years ago. With my constant dedication and learning I was able to secure a spot for being an individual contributor at the Summer of Haskell with the Haskell foundation. Taking up a Haskell course in Emurgo and now being an intern with Haskell Foundation,I have gained a solid foundation in Haskell . Additionally, my involvement in the project "Structured Error and Error Codes in Cabal-Install" as part of Summer of Haskell has honed my communication, individual work ethics and working in a dynamic environment, which I believe are essential for a successful work experience.
