I consider myself very fortunate that I have had a rewarding and enjoyable career for over 20 years in the software industry. Not every project or job has been great fun or a fulfilling experience, but I feel I have learned something in almost everything I've worked on throughout my career. My career has transitioned from consulting for clients big and small, to working as a full time employee for big Fortune 500 companies and small start-up SaaS companies. After many years of working in the Microsoft stack, in 2015 I began to work with more "open source" languages and frameworks such as Java and Spring, Scala, Go, Python, and React. In addition to becoming much more of a polyglot engineer, these last few years I have really developed my cloud skills - starting to develop solutions in AWS, GCP, and Kubernetes. I believe strongly that delivering on commitments and providing valuable software to customers is one of the best thing we can do as software engineers.
