About
I'm Zachery Dias.
I'm an estimator, cost analyst, and programmer. I work with pest control, HVAC, hardscaping, and concrete companies, so I know how contractors actually operate.
I've helped multiple companies optimize their software and restructure their pricing strategy. I've also helped with marketing and automation, built estimating templates and estimating programs, and prepared estimates across trades.
I've been doing mathematical programming since 2012 and have read over a dozen books on running home service businesses. I've taught calculus at UMass Dartmouth and algebra at Wentworth Institute of Technology, so I'm used to explaining hard numbers in plain language and training people on new systems.
