Dean Casalena

I am a versatile, hands-on software engineering leader. My experience has been on nimble, high-output teams, where I've established cultures of productivity and excellence. While ensuring our top priorities are always business outcomes, I’ve created working environments in which collaboration thrives and engineers flourish.

I have honed a philosophy that supports scale and longevity, prioritizing the clean-up of legacy systems and debts, and making codebases readable and flexible for the future. Read on for specific impacts, awards, patents and press.
