Image if you'd just graduated college, you now have a BS in some engineering field and a MS in either engineering or computer science, both from reputable schools; and/or possibly a Ph.D in a similar field. You've already established yourself in a few reputable engineering organizations via internships during undergrad. You accepted a job with an engineering company at age 23 with a starting salary of $80k-90k. You've produced multiple independent projects in the past showcasing your aptitude for engineering and programming to develop your portfolio, and you plan to pursue similar projects or freelancing in free time for profit (apps, websites, etc.) Now you've just acquired a lump sum of $400k.
What do you do? What options do you have? What are the technical implications?
