Jerryafr
Hamed contributed to the chainflip-sdk-monorepo by developing and optimizing backend features for swap operations over a four-month period. He implemented automatic slippage calculation and persistence for swaps, enhanced event handling for deposit tracking, and introduced payload storage for improved transaction auditing. Using TypeScript, JavaScript, and SQL, Hamed added database indexes to accelerate swap and fee queries, directly improving system scalability and reliability. He also extended the BTC swap retry window to increase transaction success rates. His work demonstrated a strong grasp of API development, database optimization, and full stack engineering, delivering targeted improvements with clear business and technical impact.

Oct 1, 2025Month: 2025-10 Consolidated summary for chainflip-sdk-monorepo focusing on BTC swap reliability improvements. Key features delivered: - BTC Swap Retry Duration Enhancement: increased the recommended BTC retry window from 15 minutes to 30 minutes to improve reliability for BTC swap operations. Affects QuoteRequest.ts and related test snapshots. Commit: 0d42dc8a2df2a7cb528e75b50c50c0c146564d09 (PR #1442). Major bugs fixed: - Updated and fixed test snapshots to align with the new 30-minute window, addressing test failures and CI noise related to the duration change. Overall impact and accomplishments: - Improved reliability and predictability of BTC swap flows, leading to smoother user experiences and fewer failed swaps due to tight retry windows. - Demonstrated end-to-end impact across the SDK monorepo with a single, well-scoped change. Technologies/skills demonstrated: - TypeScript code changes in QuoteRequest.ts, test snapshot maintenance, and monorepo coordination; strong change hygiene with clear commit messaging and traceability. Business value: - Higher BTC swap success rates, reduced support friction, and increased user trust in the BTC swap experience.

May 1, 2025May 2025: Delivered targeted performance optimization for the Swap module in chainflip-sdk-monorepo by adding database indexes to Swap.nativeId, SwapRequest.nativeId, and SwapFee.swapRequestId. This optimization reduces query latency for swap lookups and fee assessments, enabling higher throughput for swap operations and better scalability. Commit: 5b4ec1cd14a9a2e2052c7b424bc887db3b6e58c4 (chore(swap): add indexes to swap, swapFee and swapRequest tables) in repo chainflip-io/chainflip-sdk-monorepo. Impact expected to improve queries across the swap lifecycle and support growing user demand.
