Technology Startups

你一个人，但需要做 5 个人的事。 *You're one person. But you're doing the work of five.* 需求文档？你写。代码架构？你定。测试？你跑。部署？还是你。 *Product spec? You write it. System architecture? You design it. Testing? You run it. Deployment? Still you.* 这不是抱怨，这是 Solo Founder、独立工程师、技术 Lead 的日常现实。 *This isn't a complaint — it's the daily reality of solo founders, independent engineers, and technical leads.* *** 哈佛商学院今年刚发布了一项研究：他们跟踪了 200 名工程师长达 9 个月，结论出人意料—— *Harvard Business Review recently published a striking finding: they tracked 200 engineers over 9 months, and the conclusion was counterintuitive —* **用了 AI 的人，工作量反而增加了。** ***People who used AI ended up with more work, not less.*** 速度更快，被分配更多任务。工具更多，注意力更碎片化。AI 放大了原有的工作节奏，而不是改变它。 *Work faster, get assigned more. More tools, more context-switching. AI amplified the existing pace of work — it didn't change it.* 这项研究说中了很多人的感受：AI 没有给我们自由，它只是让我们更忙。但这也说明——问题不在 AI，在于我们怎么用它。 *This research captured what many of us already feel: AI hasn't freed us — it just made us busier. But that also means the problem isn't AI. It's how we use it.* *** 本次分享，讲者将从自己的真实项目经验出发，拆解他如何用 **Agentic Engineering** 方法论，真正实现了一个人跑出整个工程团队产能的工作方式。 *In this talk, the speaker will draw on his own real projects to break down how he uses the **Agentic Engineering** methodology to genuinely achieve the output of a full engineering team — as one person.* 不是让 AI 帮你聊天，而是让 AI 成为你的产品经理、工程团队、工程文化和 DevOps—— *Not using AI to chat — but making AI your product manager, your engineering team, your engineering culture, and your DevOps.* 分享将以 **10 DOs & Don'ts** 为主线，每一条都有对应的真实场景。10 个 DO/DON'T，是他从中整理出来的实战清单。 *He's been there. The 10 DOs & Don'ts are the practical checklist he built from those mistakes.* *** **你将带走什么 · What You'll Take Away** 不是理论框架，是一套当晚就能用的判断标准： *Not a theoretical framework — a set of judgment principles you can apply the same night:* * 什么时候用 Claude，什么时候切 Codex，什么时候用 Raycast *When to use Claude, when to switch to Codex, when to reach for Raycast* * 为什么"提问前先优化提示词"能把输出质量翻倍 *Why optimizing your prompt before asking can double output quality* * Plan Mode 和直接对话的区别，以及在什么情况下必须用 Plan Mode *The difference between Plan Mode and direct chat — and when you must use Plan Mode* * 如何把反复有效的提示词固化为跨项目的 Skill 资产 *How to crystallize effective prompts into reusable Skills that compound across projects* * 如何搭建一套多机可同步、一行命令恢复的 1 Man Company 工程环境 *How to build a 1 Man Company engineering environment: portable, multi-machine, one-command recovery* *** **适合谁来 · Who Should Attend** 正在用 AI 写代码、但感觉还没找到节奏的工程师。独立开发者或 Solo Founder，想把个人产能天花板再往上推一层。对 Agentic AI 感兴趣，但还没有实战经验可以参照的技术人。 *Engineers who are using AI to code but haven't found their rhythm yet. Independent developers or solo founders who want to push their personal productivity ceiling higher. Technical practitioners curious about Agentic AI but without real-world reference points yet.* 不需要提前了解 Claude 或 Codex，只需要有过"AI 没帮上忙"的困惑，就值得来听一听。 *No prior knowledge of Claude or Codex required. If you've ever felt that "AI just isn't helping me the way it should" — this talk is for you.* *** Speaker： Bryan Zheng， Founder of Startup4Chinese, developed several in-house products for a crypto data analysis firm. *** **Fee: $25 per person**, with fresh tea and exquisite snacks served. ***Special thanks to Jiamu Tea House.*** https://www.instagram.com/jiamuteahouse.ca/ Started in August 2017, our mission is to **inspire**, **empower**, and **connect** entrepreneurs not only among Chinese but beyond.

In a diverse, fast-moving city like Toronto, it’s easy to be surrounded by people yet still feel unsure where to start when it comes to making new friends. As adults, our routines get full, circles get smaller, and meaningful connections don’t just happen by chance.

If you’ve been wanting deeper connections but didn’t know where to begin, this is your place to start. **Book tickets now & save money -** [https://toro14thmarch.eventbrite.co.uk](https://toro14thmarch.eventbrite.co.uk) \*You can use any debit or credit card to purchase your ticket at PayPal checkout.

Let’s do some coding together at a cafe! No more working alone in the weekend. Here, we write code together. And I mean together together. Not occupying-the-same-space-but-separate together. Here’s how it works: Jennifer brings her mobile app project, tells everyone that it is like Pinterest for recipes and she’d like to work on the nav bar. Paul and Chloe think Jennifer's project is fascinating, and they join the group. They gather around Jennifer’s laptop and work on the nav bar for 2 hours. Jennifer is the one typing out the code while Paul and Chloe research, brainstorm, and offer suggestions. If you’re feeling stuck on your own project or need a motivation boost, bring it to mob programming! Want to learn by watching how others code and solve problems? Join someone else’s project at this event! Oh and we love your half-done projects that you are a bit embarrassed to share. Absolutely bring those to the event! **Discord**: We use Discord to share screen & code snippets during the event. Also feel free to share your projects here before the event! https://discord.gg/Da9fZFxPfs **Event policy**: * We have 0 tolerance for harassment. * We don’t allow the projects that are not meant to be shared in public such as school assignments, interview tasks, or trade secrets. * The goal is to write code. We discourage you from pitching business ideas here, doing code reviews, or spending the whole event on planning what to do. * Please buy a drink, and tip the barista well.
