Background

2018-2020
Right after university in 2018, I made the decision to move to China, learn Chinese and start my own company. After meeting my co-founders at Tsinghua university, we set out to build a data analytics platforms for influencers (i.e. KOLs). I learned about the intricacies of company building and nuances of team building. We entered an accelerator and raised funding, however our company ultimately failed.

2020-2022
With my second company, I wanted to fix a problem that I faced myself. A lack of software engineering skills. I set out to build a tech education company, to teach 250+ students AI development using fast.ai (https://github.com/unpackAI). I learned Python, PyTorch and developed courses to understand and quickly build AI prototype-level products.

2022-now
I started transitioning from Product to Software Engineering, joined a coding school called 42, started an onchain game project called PixeLAW that is funded by Starknet, and joined Nethermind as a Blockchain engineering intern where I work on ZK-proofs. I am a dedicated and value-driven builder that aims to maximise my impact.
