Bruno developed comprehensive developer-facing documentation for the Stellar Payments API, focusing on C-Account payment flows within the stellar/stellar-docs repository. He designed and authored guides that clarify protocol differences, memo handling, and API usage, aiming to streamline onboarding and reduce integration complexity for new developers. Using Markdown and leveraging skills in API integration and protocol design, Bruno ensured the documentation aligned with both Horizon and RPC APIs. He collaborated closely with co-author Bri Wylde to maintain editorial consistency and synchronized documentation routes, resulting in a robust resource that improves integration reliability and supports future documentation updates without introducing bugs.
