In the past, I usually worked with the international team.
And in my spare time, I also develop some side projects.

None Capital
2023/03 - Present
Taipei, Taiwan
None Capital assists Web2 companies in their transformation by integrating blockchain technology into their business model.
I led a frontend team in creating a cross-platform cryptocurrency app from scratch using React Native for both Android and iOS. This involved project initiation, architectural design, and the entire deployment process.
During this project, I also integrated a CodePush mechanism, enabling seamless and hassle-free over-the-air updates for the app.
In this role, I consistently took on the role of a problem solver and regularly provided solutions based on the pros and cons of each option.
Engineer Lead / Blockchain engineer
Hashgreen
2022/03 - 2023/02
Taipei, Taiwan
Hashgreen is a startup dedicated to developing the Chia blockchain.
As a senior developer at Hashgreen, I led the development of a crypto wallet extension from scratch.
I designed and implemented transfer features, including payment signature, to ensure secure and seamless transactions.
Additionally, I provided technical leadership to the engineering team, guiding them through the intricacies of Hashgreen and helping them develop their skills.
In this role, I gained a deep understanding of how coin set modal works and how to leverage it to optimize wallet functionality.
I also delved into the complexities of the Chia puzzle, condition, and solution, which were essential in ensuring the smooth operation of the wallet. Finally, I became proficient in Chialisp, which I leveraged to create custom scripts and modules for the extension.
