# William de Rivera > Senior Software Engineer at HubSpot Location: Cambridge, Massachusetts, United States Profile: https://flows.cv/williamderivera I am an experienced and skilled developer experience working with many different languages, frameworks, and services. I am highly adaptable, like to learn new technologies, and collaborate with other engineers. I have accumulated professional work experience working for engineering companies as an intern before I started college to a co-op learning from smart engineering mentors and as a full time employee. I like programming in every aspect from the the collaborative nature of working in engineering teams to the excitement that comes from finding the solution to a tricky problem.
