More About Me.

I started my career mastering Web2 architectures, but the paradigm shift of Web3 captured my imagination.

I thrive on building fast MVPs and refining them through real customer feedback.

Beyond code, I love hiking mountains, gaming, and sports. I also enjoy cafe hopping and mentoring others.
