TL;DR: When you move from senior developer to team lead, you stop being measured by your own code and start being measured by what your team ships. Your day fragments, your most valuable work becomes delegation, reviews and decisions, and communication turns into a core engineering skill rather than a side task.
I made this move at ProLance IT, going from Senior Web Developer to Web Team Lead for a team that has grown to 15+ developers. Nobody hands you a manual. This is the one I wish I had, written for developers who are about to make the jump or have just made it.
Key takeaways
- Your output is now the team’s output. Your personal commit count stops mattering.
- Stop taking the hardest ticket. You will be in a meeting when it needs you.
- Code review becomes your highest-leverage technical work.
- Write decisions down, with the reasons, so people can act without you.
- Protect focus time on purpose, for yourself and for the team.
What actually changes when you become a team lead?
The biggest change is how success is measured. As a senior developer, a great week meant I shipped a hard feature cleanly. As a team lead, a great week means five people shipped, nobody was blocked for long, and the client knew exactly where things stood, even if I wrote very little code myself.
That shift shows up everywhere:
- Your calendar fragments. Standups, client calls, planning, one-to-ones and review requests break the day into small pieces. Long, uninterrupted coding sessions become rare unless you defend them.
- Your questions change. Instead of “how do I build this?”, you ask “who should build this, what do they need, and what could go wrong?”
- Your mistakes get bigger. A bad technical decision used to cost you a day. Now it can cost the whole team a sprint.
Should a team lead still write code?
Yes, but less of it, and almost never on the critical path. In my first months as a lead I kept picking up the hardest tickets, because that was what I was good at. The result was predictable: I got pulled into a client call, the critical feature stalled, and the team waited on me.
Code that a lead should write:
- Prototypes and spikes that answer a technical question before the team commits to an approach
- Shared tooling, utilities and project setup that make everyone faster
- Small fixes that unblock someone right now
- Code that demonstrates a pattern you want the team to follow
Code a lead should usually hand off: anything on the critical path, anything with a hard deadline, and anything that would be a great growth opportunity for someone else.
How do you delegate without losing quality?
Delegate the outcome, not the steps, and agree on what “done” means before work starts. Early on I either over-specified tasks, which turned developers into typists, or under-specified them, which led to rework.
What works for my team:
- Explain the why. Share the business goal and the constraints, not just the ticket.
- Define done. Acceptance criteria, edge cases that matter, and how it will be tested.
- Agree on checkpoints. A quick look at the approach before most of the code exists saves far more time than a big review at the end.
- Match the task to the person. Stretch work for people ready to grow, safer work when the deadline is tight.
- Accept a different solution. If it is correct, readable and consistent, it does not need to be the solution you would have written.
Why does code review become your most important technical work?
Because review is where you shape the whole codebase at once. One thoughtful review teaches a pattern to a developer who will then apply it a hundred times without you. I wrote down the exact checklist my team uses in The Code Review Checklist I Use With My Team.
The trap is becoming the review bottleneck. If every pull request waits for the lead, the team slows to your speed. Spread review across the team, and keep your own reviews for risky changes, new patterns and developers who are still ramping up.
How does communication change for a team lead?
It becomes part of the engineering work. A lead translates in both directions: client and business needs into technical tasks, and technical risk into plain language that non-developers can act on.
A few habits made the biggest difference for me:
- Write decisions down. A short note covering the decision, the options considered and why we chose this one prevents the same debate from happening three times.
- Share bad news early. A delay reported on day two is a planning problem. Reported on the deadline, it is a trust problem.
- Estimate in ranges. I explain my full process in How I Estimate Web Projects as a Team Lead.
- Mediate, then decide. Teams will debate everything, from architecture to tabs versus spaces. Let people make their case, then make a call and explain it. Unresolved debates cost more than imperfect decisions.
How do you protect focus time as a lead?
By treating it as a scheduling problem, not a willpower problem. Fragmented days hurt developers even more than leads, so protecting focus is part of the job.
- Group meetings into one part of the day and keep the rest meeting-free.
- Make standups short and move detailed discussions to the people who need them.
- Block review time in your calendar so reviews happen reliably without interrupting your own work.
- Default to written, asynchronous updates where a meeting is not needed.
What I would tell myself on day one
- You will feel less productive for a while. That feeling is wrong. Your output moved to other people.
- The team watches how you react to problems. Calm and curious beats blame every time.
- Grow people on purpose. A junior developer who can handle the work you used to do is the best result a lead can have.
- Keep learning the technology. You do not need to be the best coder on the team, but you need to understand enough to make good decisions and ask good questions.
Frequently asked questions
What is the difference between a senior developer and a team lead?
A senior developer is measured mostly by the quality of their own work. A team lead is measured by what the whole team delivers. The lead still writes and reviews code, but also plans work, makes and explains technical decisions, unblocks people, and communicates with clients and management.
Do team leads still write code?
Usually yes, but less of it and rarely on the critical path. A lead who takes the hardest ticket becomes a bottleneck while in meetings. Better work for a lead is reviews, prototypes, tooling, and small fixes that unblock others.
What is the hardest part of becoming a team lead?
Letting go of being the person who solves the hard problems personally. Delegating work you could do faster yourself feels slow at first, but it is the only way the team grows and the only way you stop being the bottleneck.
How do you prepare to become a team lead?
Start doing parts of the job before the title: review pull requests thoughtfully, mentor a junior developer, write down technical decisions and their reasons, and take part in estimation and client conversations. These habits matter more than any single technical skill.
