Instructors
I’m a Software Engineer by day and a storyteller at heart. I have 7 years experience engineering Software at Amazon, Microsoft and Google where I have left my footprint on the AWS Console, Microsoft Word and Google Cloud. In my spare time, I write both technical and non technical content. I have published Leanpub courses on Algorithms and Data Structures and contributed to publications such as draft.dev and dev.to. I write non technical articles on my blog. I absolutely love solving problems, all the way from mysterious beginnings to the Eureka moment. Its a transformative process that I like to share through writing. Whether you are preparing for your next interview or simply reading from curiousity I hope my writing speaks to you.
