Best dev experience...a colleague who was my team lead when I joined a company as a "from-scratch" PHP developer, and gave me a ton of tips, assistance, encouragement and praise along the way. And for the bits that were not so good (on my part), he gave me constructive criticism delivered in a friendly and helpful way rather than chew me out.

And when the boss(es) of the company talked shit behind my back in meetings I was not invited to, about things they had no clue about (my performance as a developer)) he defended me and set the record straight.

Later he was demoted from team lead for office politics reasons. But was doing the same job as before, for less pay. Never complained.

His job consisted of, all at once, being the company IT/server/printer guy, first line customer support over phone and remote desktop, .NET and PHP developer, course holder to teach our customers how to use our product, and mentor to me.

Good guy. I'd give him a ++ if I could.
