PROFILE
Jamie Ford
Over an 18-month period, contributed to the chainflip-io/chainflip-backend repository by designing and delivering backend systems for cross-chain swaps, automated trading, and lending protocols. Leveraging Rust, TypeScript, and Node.js, implemented features such as oracle-driven price protection, inventory-based trading strategies, and robust fee management with refund handling. Enhanced reliability through improved error handling, test coverage, and CI/CD automation, while refactoring core modules for maintainability and performance. Integrated advanced RPC APIs, pallet development, and smart contract logic to support secure asset management and governance. The work emphasized risk controls, observability, and developer productivity, resulting in resilient, scalable DeFi infrastructure.

Dec 1, 2024December 2024 — Chainflip backend delivered two significant features that improve encoding simplicity and end-to-end vault-swap visibility, driving maintainability, observability, and API stability. The Bitcoin vault swap encoding was simplified by removing redundant op codes, with an added helper to identify the lowest unused affiliate short ID and corresponding API/tests updates. Vault swap tracking was exposed in the ingress-egress-tracker, including data structure refactors, vault swap request handling, and improved storage/serialization with encoding enhancements, plus dependency updates. These changes enhance operational telemetry, reduce encoding complexity, and support safer, faster vault-swap workflows.

Nov 1, 20242024-11 monthly summary for chainflip-backend: Delivered key features and fixes across the BTC vault flow and developer tooling, driving reliability, security, and faster development cycles. Highlights include: (1) RPC error messaging bug fix: ensured actual error content is shown instead of '{error}', reducing debugging time and improving user visibility. (2) Bitcoin vault swaps encoding RPC endpoint: added an RPC to encode vault swaps and generate raw transactions with embedded swap parameters; included tests and improved error handling to ensure secure and correct swap initiation. (3) Developer local network setup script: introduced build_and_run.sh to automate localnet setup, accelerating local development and testing. (4) Open/close private BTC channels in broker API: added RPC methods to open and close private channels, integrated with vault swap tests, and cleaned up validations for a cleaner API surface. (5) Affiliate support for Bitcoin vault swaps: added affiliate registration and retrieval in broker API and included affiliate details in vault swap encoding for broker commissions and partner tracking. (6) Bitcoin transaction reliability improvements: refactored BTC transaction creation to improve concurrency and reliability via a mutex and node input selection logic, ensuring UTXOs are locked and change is correct for vault swaps. Overall impact: improved debugability, secure swap initiation, broker commission tracking, and more reliable BTC operations; enabled faster development through a local environment script.
