If I were a young software developer solely focused on saving as much money as possible, I would: move to SF in a heartbeat, work for Facebook, Google, or Amazon, pick a mission-critical team that exposed me to systems at massive scale, and live in a van a pleasant 5-10 minute bike ride from the office. After I felt comfortable I'd start to consult on the side on weekends for up to $53k of annual tax-free solo 401k sheltered income. Life doesn't present a ton of these "sell picks and shovels to gold miners" opportunities but this is definitely one of them.
