Robert Difalco's LinkedIn

I have over 30 years of experience as a commercial software professional. As the technical co-founder of Wai, LLC I created a horizontally scalable cloud based server using Java 8, jOOQ, Grizzly, JAX-RS, Redis, Spring, Kryo, and PostgreSQL while managing mobile client engineers. I love to code and to lead high performing teams.

During my 12 years at Tripwire I created their flagship product Tripwire Enterprise which generated over 80M in revenue, introduced agile methodologies, started a UX practice to bring more design to products, was a key player in company strategy and product road maps, worked on M&A opportunities, formed a sophisticated performance testing team, received various board recognition and sales impact awards, brought in training for our development team, worked with high profile customers, and served on the executive staff.

I prefer to get things done quickly and run experiments that prove customer value. I believe that R&D and Product must have a very close relationship with the Sales organization and our customers. I am customer and sales focused and favor value over technology for technologies sake.
