044 | What Not to Build

Wed, 10 Jun 2026 06:56:42 +0000

the hard part now is choosing

My instinct, faced with any problem, is to build a solution for it — and lately I realized the harder skill is knowing what to leave unbuilt. Building has always been the slow, hard part, so being good at it felt like the whole job. That’s not where the hard part lives anymore. When we can stand up almost anything in an afternoon, the question worth asking stops being can I build it and becomes should I. The eye to see what’s worth building, and the nerve to drop the rest — that’s the skill I think matters most now, and the one I’m still working on.

043 | Six Years In, and the Illusion of Control

Mon, 01 Jun 2026 07:40:28 +0000

6-year anniversary reflection

The moment you finally get the thing you wanted, strangely, the doubt shows up. I graduated in May 2014 and have worked ever since — 12 years. On 5/26 I hit six years at Instagram and a career the 24-year-old me wanted. I thought I’d feel like I’d arrived. Instead I feel uneasy, and I’ve come to think the unease is the more useful thing to write down.

042 | Few Thoughts on Leadership Traits

Wed, 20 May 2026 07:29:46 +0000

Be a noob; admit I'm wrong; uplift others

Lately I’ve been thinking about leadership traits. I’d like to reflect on a few things. I’m sure I’ll return in a year and comment something different; but here is what I had on mind for the past 1-2 years.

A year ago I stepped into a refreshed role to cover more areas in the 40-eng org. A break-through happened in trust building with folks: we had an external conflict with a different team; I ended up protecting my engineers’ scope, navigating through different org’s incentives, and putting off the fire. These in return rewarded me with more people’s trust. A few points to reflect:

Claude Code, Antigravity

跟风Claude Code

轰轰烈烈的2025年度PSC (Performance Cycle Review, 年终评价)落下帷幕. 往年的我在这个时候特别忙, 像打仗一样写年终总结帖. 今年我患了拖延症, 到截止日期的最后一天才写完所有的feedback; 这一周我几乎所有的精力都花在Claude Code上, 学习一些流行的工作流程, 反省自己工作模式中值得改进的部分.

034 | Allies at Work

Thu, 11 Dec 2025 07:03:01 +0000

a reminder that we need allies

Today I had a rare opportunity to chat with a co-worker about our similar approach to work and the challenges we both face. I was surprised to realize how much I needed allies — more than I had previously understood.

I’m not even hiding my weaknesses or vulnerabilities; I’m just really good at not showing them at work. Navigating the workplace can feel like walking a narrow path. In recent years, I’ve often been the one setting expectations for a small cohort of peers, which leaves me with fewer opportunities to express my own struggles. Of course, I’m privileged to have support systems — a strong circle of managers and mentors. But even with them, I naturally position myself as someone with a high caliber, someone who has things under control. It’s hard to loosen up, if ever.

028 | Individual Contributor vs. People Manager 怎么选?

Tue, 31 Dec 2024 06:12:46 +0000

管理岗位, 技术岗位, 转职

今年9月, 我就遇到了做这个选择的时刻: 是继续做IC (Individual Contributor) 呢, 还是选做People Manager 呢? IC的意思就是单兵的意思, 不负责团队. People Manager顾名思义, 就是传统意义上的经理, 做管理工作.

027 | 2024 Retro

Tue, 31 Dec 2024 00:23:24 +0000

life, career, pitfalls and thanks

The highlights of 2024 were a few long-term goals coming together, both in my personal life and career. On the flip side, there were also matters that I was underprepared for, which led to harsh life lessons. Overall, the past year was a challenging but productive experience.

Why bother writing about the recent past?

Writing about the 45%–65% of my awake time is a meaningful practice for the year’s finale. Like many others, I dedicate a lot of effort to the yearly performance reviews for myself and others at work. However that only represents merely 40–60 hours per week (~35%–55% of the 112 hours of non-sleep active time). Ignoring the rest 45% — 65% seems silly.

026 | Staff Engineer, Now What?

Mon, 12 Aug 2024 00:59:06 +0000

Senior Engineer vs Staff Engineer

For a long time, I have been chasing after the prestigious title of senior engineer. I was mentally exhausted when I achieved it a few years back. Leading up to this latest title update, my anxieties piled up— what’s next? (vol.15 小宇宙FM)

Senior Engineer, 2022

In 2020, I flopped my interview for the senior engineer role at my dream company. Through a series of debates, I also gave up on the senior engineer role at Uber for which I aced the interview. I proved that I was worthy of a senior title, even just for a few hours at San Francisco Uber HQ. But on the flip side, I picked the lower rank in favor of my dream company.

断舍离和独立成长

① Dead Code Lives Forever

那些不再用的代码, 通常被叫做 dead code.

每隔一段时间, 这些不用的代码会被手动清理掉. 不然, dead code会将系统变得臃肿, 难以维护, 有时候还会浪费一些计算资源.

Sun, 11 Feb 2024 21:08:57 +0000

Corporate Culture, Yearly Review, Constructive Feedback

A private jet landed at SF airport, breezing through the runway.

Delayed Flight

Yeah, my regular United Airlines flight was delayed. The storm was right on. Less did I know, that aside from the bad weather, I was heading into a personal life storm in those two weeks. This story will be reserved for another time.

A bit emotional, with mixed feelings - I sat back, opened the laptop, and started typing.

023 | 2024: Resetting and Learning

Tue, 09 Jan 2024 08:33:32 +0000

TL Role, Inspirations, Catching Up With AI Trends

It was in 2020 when I first acknowledged a gap in the content I was creating. With a new job at stake, 'messing around' no longer seemed like the right choice. Delving deeper, I realized my impostor syndrome stemmed from a question: "Who am I to advise on various software engineering topics?" After all, I had only recently found my path, while others had propelled large tech companies forward years before me. This realization left me with a lingering fear of not providing value.

Navigating the Tech Bubble Through Layoffs, ChatGPT 4.0, Newsletter in 2024

① Navigating the Tech Bubble in 2023 at Silicon Valley

2023 was like a rollercoaster for many of us in the tech industry, especially in Silicon Valley. We experienced the tech bubble making its best impression of a popped balloon.

This year put my ego on a diet. Despite the ups and downs, this year taught me invaluable lessons. One key takeaway I want to share is the power of optimism during tough times.

021 | 裁员潮落, AI风起

Thu, 22 Jun 2023 00:43:54 +0000

程序员会被取代么?

这期podcast讨论了2022年科技行业的情况，以及未来几年是否还应该投入这个行业。小宇宙链接

在当今这个时代，计算机科学技术是必不可少的基本技能，无论是在个人生活还是职业生涯中，都扮演着重要的角色。虽然现在实习和工作都难找，但这些困难也会让人成长。在找工作时，我们可能会遇到很多困难，但是这些挑战也会让我们更加坚定自己的方向和目标。

另外，讨论了AI是否会对软件工程师的就业安全造成影响。虽然AI在当前的技术水平下还没有取代技术主管的能力，但是它正在不断地进步和发展。随着时间的推移，AI技术将不断地改进和完善，它将在未来发挥更大的作用。然而，在这个时刻，它还没有完全取代人类工程师的工作，因此，我们应该利用更强的生产力，去做其他事情，而不是担心AI会取代我们的工作。

Layoff, Senior Blocker, ChatGPT

① 第二波 Layoff

我们的行业似乎进入了下一个纪元. 一面是吵吵闹闹的AI/ChatGPT, 一面是惊心动魄的Layoff. 这两者还并没有直接的关联, 但很多人担心不久的将来, 他们也会被赋予因果关系.

011 | 找bug的时候，我都在想些什么

Thu, 28 Jul 2022 04:14:58 +0000

几分钟，谈谈压力

有时候我想，每个人所承受压力是不是守恒的？随着年纪，从对未知的压力逐渐物化成有形的压力。

这几年，压力除了来自于经济，工作，渐渐又多了一层意识形态上的压力。我做过一个实验，用两个不同的YouTube账号，一个看Trevor Noah，一个看Ben Shapiro. 看了一段时间，想法开始变得多元。这样看一段时间，你会很好奇对于同一件事不同人的看法，逐渐就会进入一个自我批判的怪圈里面，只活在一种意识形态里面，虽然很容易达到逻辑闭环，但那是个多么幼稚的选择。

tbh, don't be that bottleneck

你恐怕会想, 说的是工作能力缺失的故事? 恰恰相反, 今天说的是那个实力全组最强的人, 那个全队的瓶颈.

THE STORY

17年, 在亚马逊工作了一年多, 我接手了一个中型的项目, 重置一下我们内部的一个管理网站. 想法很简单, 就是重做网站, 加上一些新功能, 再保证未来可以添加新功能.

006 | 导师的辛酸泪

Tue, 10 Aug 2021 14:27:57 +0000

Top of Mind: Mentorship

近一年来, 我在琢磨, 什么是出色的导师(Mentor)? 如何到达那一步?

导师与老师的角色有很大的区别: 前者似乎更多在提出问题, 而后者更多在解答问题. 把我们放在 1:1 会面的语境里, 导师也许更多是用问题来帮助对方自己找寻答案, 而老师会直接有效地教会一件事的来龙去脉.

当然是headcount刚放出来的时候

最近有两个美国朋友, 先后跟我联系, 问我当年面试的经验. 我发现他们有个共同的特点, 就是很难接受一个'慢慢来'的设定 - 我不知道是何原因, 也许是直男, 也许是缺乏面试经验. 既然他们问了我意见, 那我就耐心解释, 为什么面试的时机很重要.

2021三月底, 我用视频记录了来到新公司的沟通瓶颈. 因为语言环境的改变, 知识领域的变迁, 我们势必会在新公司进步缓慢. 那期视频, 以公司会议为切入点, 聊了三个可攻可守的角度: 1/ 把控会议的开头, 2/ 提前了解沟通的对象, 3/ 会议后总结跟进.

在计划项目的时候, 我通常会把任务分析透彻, 描述得通透, 然后再发出去给别人做. 仿佛写入的细节越多, 接到项目的人成功率就越高.

逐渐, 我发现工作中有两种人: 1/ 不需要你的分析, 他也很快琢磨明白. 2/ 你分析得再透彻, 他还是很混乱, 甚至看不懂任务明细.

Sat, 03 Jul 2021 10:01:14 +0000

工程文档101攻略

我曾酷爱文章. 续过人家的小说, 编过自己的故事, 琢磨过用字, 也自诩高明地打过笔仗.

后来我写代码了. 代码无情, 有结构但没故事, 有语法但没偏好. 代码的完成意味着一个过程的结束, 而非拉开一场演出的帷幕. 这些都跟写文章写小说差之千里.
