You need to understand very soon that you can no longer have projects assigned to you. Everything your management asks you to do is actually something that they want you to ensure gets finished- you are not supposed to do it yourself. Delegate, follow up, and guide someone else to do it.

The moment you take a project on by yourself, you’ve become a huge bottleneck for your entire team’s productivity. Your team needs your guidance and help, and you can’t offer that if you’re designing, coding, and debugging a project on your own.

98% of coding for you should be paired programming from here on out, where you are not the developer at the keyboard. You are providing suggestions and guidance so that experience can transfer to your junior team members.

Edit: You are not just a “tech lead,” you are a manager if you have direct reports.

Hope you like Jira, confluence, and neverending meetings.

Tech Lead means different things at different companies. You say you have direct reports, do you mean you do their performance evaluations or not? If so then I'd call that a manager. To me that's where the difference is. If you handle any of the "HR" parts of the process (for lack of a better term) then that's a manager.

I ask what you mean because the advice differs.

For example, I was a tech lead but not a manager. It was sort of funny, sometimes my team would ask me if it was okay if they took off or left early and I'd explain to them that "I'm not your boss" lol. Basically I'd tell them I have no problems with it but I'm not really the person who can grant that or whatever. The sort of role a tech lead has (at least in the context I was in) was maybe something like a team captain. If folks didn't have specific tasks in the sprint they wanted to work on I'd assign it to them. Most folks never really had a preference but I never wanted to seem like I was being bossy.
