Not a direct answer but some of the things I'm most proud of that will probably affect lives of people not born yet: Convinced my boss to give the Polish woman who cleaned at the site I worked at a position as IT consultant (in Norway). She married a long time friend of mine a couple of years later (but I luckily had no influence on that except helping her getting her a job worth staying in Norway for.) Helped one man who did a great job to but lacked formal education to keep his job by leaving a well paid job at the same team very voluntarily (although not as big a sacrifice as it might sound. I found the job extremely boring.) Recently I also helped my neighbor to get a 50% pay rise. In between I've made software to simplify life for people organizing work in non profits. (Stupid web page connected to a sms api. Almost had to chase them away from it as better options emerged and I got more and more afraid of getting hacked and leaking a whole lot of data on the Internet.)
