Work History

March 2026

1 Commits

Mar 1, 2026

March 2026 monthly summary for sfcompute/cli: Hardened start date handling by validating -s/--start and surfacing clear errors for unparseable inputs. This prevents silent fallback to the current date, improves UX, and strengthens date-based workflow reliability.

October 2025

1 Commits

Oct 1, 2025

October 2025 monthly summary for sfcompute/cli: Focused on robustness of the order lifecycle. Delivered a critical bug fix in the buy and sell order status polling that explicitly handles 404 responses for non-existent orders, returning undefined to prevent downstream failures. The change is captured in commit 421870c3b5eded602bb891dd03a84fc6c8d6eecc with message fix(buy): explicitly handle 404 when polling for status (#212). This work enhances reliability of automated order tracking and reduces error propagation in production.

September 2025

Sep 1, 2025

In September 2025, sfcompute/cli delivered a reliability improvement for order polling and fixed a race condition that could cause missed order status updates. The changes center on replacing the interval-based polling with a recursive setTimeout, ensuring polling proceeds only when an order is not found, thereby improving correctness and robustness of order status checks. This was implemented in the sfcompute/cli repository with a targeted code fix, tracked as commit 813a26cf68816848045ccf8b6c491cf6b3d36f9b (fix: fix race condition in poll loop (#190)).

In August 2025, sfcompute/cli focused on stabilizing and refining rate calculations for buy orders under very short durations. No new features were released this month; the primary effort was a critical bug fix that corrects Buy Order Rate Calculation Timing by introducing a roundDateUpToNextMinute function to interpret NOW as the start of the next minute. The fix was applied to buy order placement and scale creation workflows, ensuring accurate rate display and reducing edge-case failures in near-term order scenarios. This change is linked to commit e3dd769ef68cdd5f447548374bb38303f28fccf4 and addresses issue #187.

June 2025 (sfcompute/cli): Delivered a critical parameter normalization fix to ensure the colocate option is always treated as an array. This corrected behavior improves buy order placement and quote retrieval when colocate_with is provided, aligning CLI behavior with API expectations and reducing edge-case failures in trading workflows.

May 2025

May 1, 2025

May 2025 monthly summary for sfcompute/cli focused on delivering increased configurability for procurements and improving documentation accuracy. Key work included the Colocation Strategy Feature for the CLI, integrating new options on the create command to define colocation behavior and updating procurement displays to include the strategy, supported by a refactor to integrate with CLI command parsing. In parallel, official documentation links in CLI help texts were fixed to point to accurate, up-to-date information for SF Scale procurement strategies and the scale command, reducing user confusion and support overhead. Business value delivered: enables precise colocation configurations in procurements, improves user experience with accurate docs, and enhances maintainability through refactoring of the CLI parsing logic.
