Tokyo Tech Lead is a personal tech career growth newsletter/blog run by Adler Hsieh and hosted on Substack. Its core focus is not teaching a specific programming language or framework, but helping software engineers “think like senior developers.” It is aimed at people who want to grow into Senior Developer, Tech Lead, or Engineering Manager roles.
The content mainly includes weekly articles, short notes, career growth advice, and engineering leadership experience. Topics mentioned on the captured pages include how engineers can demonstrate ownership, how to tell whether you are underperforming, managing low-performing team members, and whether engineering managers should still write code. Subscribers also receive a “90-Day Senior Dev Roadmap,” designed to help readers understand senior-level expectations in companies, identify opportunities within their teams, and build a repeatable growth system. The site also provides an entry point for Career Decision Consulting and opportunities for guest contributions.
The page shows that users can subscribe via Substack, but it does not disclose clear pricing, the boundary between free and paid benefits, or membership tiers. For now, it can only be determined that it includes at least a newsletter subscription mechanism; whether there is paid content needs to be confirmed by visiting Substack.
The advantage is that its positioning is very specific, focusing on communication, leadership, ownership, and team influence—areas often overlooked in software engineers’ career progression. The author states that he has over 10 years of experience as a software engineer, Tech Lead, and engineering manager, giving the content a strong personal-practice perspective. The Substack format also makes it convenient for email reading and long-term following.
The downside is that it is more like a personal knowledge-sharing channel than a structured course or bootcamp. Its content quality and level of systematization depend on the author’s continued updates. For users who want to learn hard technical skills such as algorithms, system design, or cloud native technologies, it can only serve as a supplement for career soft skills. In addition, the page does not show clear paid plans or service delivery details, so its commercial transparency is average.
It is suitable for engineers who already have some development experience and are preparing to advance to Senior, transition into a Tech Lead role, or begin taking on broader team influence. It is also useful as a reference for engineering managers, technical writers, and developers who want to build a personal brand.
This site is based on Substack. The stability of accessing Substack from mainland China is uncertain, and users may experience slow loading, limitations with email subscriptions, or restricted page resources. Overall, it should be considered “partially restricted.”
