Hi, I'm a recent PBA graduate and have just started contributing to polkadot-sdk. I would be incredibly grateful for the opportunity to join the fellowship program as a humble learner at the rank of I Dan. I've been fortunate to receive excellent mentorship and guidance from @ggwep and @gupnik, which has helped me begin making meaningful contributions.

While I still have a lot to learn, I'm deeply committed to growing my skills and becoming a valuable member of the Polkadot community for the long haul. I'm excited to dive in, absorb knowledge from the talented developers here, and steadily ramp up my contributions in the months and years ahead.

So far, I've made a few initial PRs to polkadot-sdk:

• paritytech/polkadot-sdk#3446

• paritytech/polkadot-sdk#3491
