4 Months as a Tech Lead


After 8 months joining a new company, I was promoted to Tech Lead in Aug 2025 at my $current_company. I am now leading a team that ships the company’s SaaS product.

When I first transferred into the team, there were only 2 engineers, 1 QA, and 1 Product Manager. The business grew so well and we’re planning a lot for next FY. Now, 4 months later, the team has grown to 3 backend engineers, 2 DevOps engineers, 2 QAs, and 1 Product Manager. As a first-time lead engineer, leading a cross-cutting squad, it was overwhelming at first to keep everything in my head.

Mandates

In the beginning, I was given clear mandates to:

Here’s how I tackle these problems:

Improve the quality of feature delivery

Before I joined the team, they were steadily delivering features. But when they’re working on complex features, they’ve had to change their plans a couple of times during development. This situation is not ideal because it would extend the project timeline, and much of the development done would have to be redone.

What I did was, the team and I would gather and discuss the solution thoroughly, prepare a tech spec document, and get feedback from across the company before executing the plan. This way, we could uncover problems and pitfalls, pivot before spending time implementing the solution. There is no perfect solution, but as long as we are aware of the trade-offs we’re taking, we are good.

I personally spend a lot of time writing and reviewing the tech spec in the team. The clearer the tech spec, the smoother the project delivery is. Not to mention, I also spend a lot of time reviewing PRs.

“The problem is already solved when you start writing the code” - saw this somewhere in LinkedIn

I’m glad that my previous experience working with cloud, backend, distributed system, database, and (slight) frontend helps the team.

What’s changing: we’re writing a clear tech spec and task breakdown rather than a vague one.

Improve the speed of feature delivery

In addition to the clear tech spec mentioned above, here are some of my efforts to improve feature delivery speed:

Improve infra & product stability

Before I joined the team, the infrastructure was not exceptionally stable. After talking to the team, we found out that the team’s practice wasn’t using the dev environment as much.

What’s changing: we adopted a shift-left mindset and use the dev (and soon, the ephemeral local/test environment) more effectively. The infrastructure is much more stable since then.

I’m also trying to encourage the team the mindset “You should be able to touch any part of your code”.

First time doing people management

Throughout my career, I have had more than 8 managers. Some of them were great; some were not. From those experiences, and also from my readings, I have come up with my own guiding principles on managing people:

What helped me get here

New challenges

Now that the team members are so productive, we are encountering a bottleneck in testing & QA. As we hire more QAs, how do we keep everyone productive with our setup.

Other than that, I’m also trying to balance between managing up, managing down, and essentially stakeholders from all directions. This is new to me because, previously, as an Individual Contributor, I didn’t have to consider others.

I really appreciate everyone who trust me ☺️
