Since graduating from PBA Wave 2 early this year, I have been privilaged to work within the Parity FRAME Team, under the mentorship of Kian.
During this time, I have made non-trivial contributions to
- Substrate core utilities
- Polkadot and Kusama runtime code
- essential Substrate developer tooling
I've been thoroughly enjoying my work thus far, and, feeling aligned with the ethos and direction of the Polkadot network wish to express my interest in joining the Fellowship.
Thank you for your consideration.
