πŸš€ Experienced Software Engineer | Tech Leader

πŸ§‘πŸΎβ€πŸ’» Profile

I am an experienced software engineer who has been building software / applications professionally since 2002. I started programming way back in school using Pascal / C (around 1996) and learned my craft through developing, architecting and leading software projects. I love to code, I like to help people through code and I enjoy working with a good team of developers.

Currently I enjoy working with TypeScript, Kotlin, Python and DevOps (AWS / Terraform). I was a Java programmer from 2002-2011, Ruby programmer for 3-4 years after that. Now, I mostly work with TypeScript / Python or (modern) JVM languages like Kotlin. I am also interested in functional programming languages like Clojure.

I have developed numerous mobile / web applications and worked on building large enterprise software for McKinsey & Company, Klarna, Morgan Stanley, Goldman Sachs, Ergo among other clients in the US, UK, Europe and Japan. I have lived and worked in as many as nine countries.

On the personal front, I now live with my family in the beautiful city of Berlin, Germany πŸ‡©πŸ‡ͺ. I am trying to learn German and plan to live here as long as God permits. I believe in Jesus who has blessed me all my life from a small town in India to a major city in Europe. Jesus also healed me from a difficult disease in 2020.
