Job/Occupation from natal chart

It's impossible to specifically determine a person's occupation from their birth chart, let alone what company they work for. All a birth chart does is give a very broad impression of what they would need in their working life. Within that, there's a very, very wide range of possibilities. The birth chart does not tell us which of those possibilities they've chosen.

Based on the chart, this person wouldn't necessarily work in a tech-related field at all. He might, sure, but he just as easily might not. And if he does work in tech, he could be working for any tech company as far as his chart is concerned. Or for a government. Or he could be self employed. The natal chart does not determine that.

And how do you know his birth information? Do you have his permission to post it in a public forum? See my edit of your first post.

If you know him well enough for him to have told you his date, time, and place of birth, it's very odd that you don't know what he does for a living.
