I'm an activist, and I think leveraging technology is critical in being able to organize and do outreach.
Hopefully inspiring others to code/be a technologist, and helping those pursuing it to be successful. Offering low-cost to pro bono services to influential individuals or non-profits with causes I support in my free time.
Be more inclusive--actually inclusive, and not just ticking off checkboxes for diversity and hiring vulnerable people into toxic work environments. Sensitivity training or whatever it takes--invest in it.
