Need advice.

22M 5’6 112lbs. Started my journey early April at 105 lbs so I’ve gained a little since then but it’s too slow for my liking. My goal was to eat around 3000 and it actually hasn’t been hard to eat but sometimes with work I don’t have the time. But I think the biggest issue is I’m burning too many calories at work, I walk on average 15k steps per day. If I completely locked in with getting my calories in, how many calories should I aim for I wanted to reach 130 say by mid July.
