I graduated CS at the age of 27 and thought I'd be at a disadvantage starting out in the industry due to it. If anything the couple more years seems to have helped me out quite a bit as I found it made me more relatable to the more senior technical people and management.

In the modern dev shops now the soft skills you've developed in the additional years you've had before getting into development will give you quite an advantage since 99% of places aren't just heads down coding anymore.

Where I've found I have a disadvantage is in my non-work commitments and free time outside of work. The younger guys can spend their evenings and weekends working on side projects, going to hackathons or just learning something new, whereas I come home to the family and try to spend quality time with them, do my share of the work in the upkeep of the house, yard, etc.

We only get one shot at life so you're never too old for anything in terms of what you want to spend 40+ hours a week doing to finance your life.
