In 2018, Kellen moved to Tyler Technologies. He would switch focus from defense to local government. Kellen was responsible for writing custom payment processing software (similar to Stripe) for processing users utility bills. This allowed Tyler Technologies to save cost on payment processor fees which greatly increased revenue for the company and thus increased revenue for shareholders.
In 2022, Kellen moved to Tasso Inc. He would switch focus to biomedical technologies. Tasso is a startup company that makes devices to draw blood via suction (in a painless manner). This revolutionary technology will allow people to get blood tests from the comfort of their home. Kellen writes the APIs for customers to place orders for said devices. Roughly 80% of order traffic goes through Kellens software.
