Ronald Hunter

Tech Lead

A multifaceted person with an upbringing in design and Software development. Having knowledge in all three gives me the ability to better communicate and understand different departments and individuals. I've worked for both startups and Companies, both local and remote. I've been known to be a funny guy so the workplace is never aggressive or negative, I care about my teammates and am always there to listen and see their viewpoint on things to gain a better perspective.

I have currently narrowed my view on a few technologies to gain a better mastery of them (Python, Javascript, GraphQL, AWS) but this does not mean I have stopped seeking the bleeding edge tech that bubbles up from time to time, learning is the best thing.
