Argument

RegionX Maintenance

Throughout this period, I have continued to actively maintain RegionX, the primary Coretime management application in the Polkadot ecosystem. RegionX remains the go-to interface for teams and projects to manage their Coretime allocations.

Joining Parity

In March, I joined Parity's runtime team. Since joining, I have started working on the following:

• Pallet Broker Refactoring & RFC-17 Implementation: Currently working on refactoring pallet-broker and implementing RFC-17: polkadot-sdk#11351.
• On-Demand Pricing: Initiated a discussion about a potential new pricing model for on-demand Coretime that is tied to bulk Coretime prices.
