I think doing projects and posting on github is good. If you have a undergraduate degree, consider taking graduate courses in the field. I had an undergraduate civil engineering degree. When I decided to change fields in my late 20s I looked into taking computer science classes at night while working, some friends who were history majors did the same. From there I got a coop job, I then went back full time for a masters in computer science. The database, data structures and operating system classes I took in grad school have been really valuable in my career. The only thing about this route is the classes are pricy and you have to apply. This is what I did a pace (Its different, its been over 10 years): http://pace.smartcatalogiq.com/2015-2016/Graduate-Catalog/Schools/Seidenberg/Graduate-Degree-Programs/Graduate-Certificate-Programs/Software-Development-and-Engineering http://pace.smartcatalogiq.com/2015-2016/Graduate-Catalog/Sc... Northeastern is where some friends got certificates, I did my masters: http://www.ccis.northeastern.edu/academics/certificate/ http://www.ccis.northeastern.edu/academics/certificate/ I've taken some online edX classes to keep skills up
