Building free software for NYC nonprofits, small businesses, and startups.
You get paired directly with a company that needs software built. They have a real problem and you build the solution with a team.
Write code that runs in production, not just in a class repo. Every project ends with a deployed product that real users depend on — and something concrete you can show in interviews.
Step up and own a project from start to finish. Manage the client relationship, make technical calls, run a small team. Reach out if you are interested.
