Worked on erigontech/erigon and starkware-libs/cairo, delivering targeted backend and documentation improvements. Developed a fork choice mechanism in Go that keyed optimistic store candidates by blockRoot, enhancing the reliability of parent-child linking and execution checks in blockchain consensus logic. Clarified API error semantics for MethodById and EventByID, reducing potential misuse by aligning documentation with actual error-return behavior. Improved Cairo documentation by updating WideMul deprecation notes to reference the public API path and adding direct corelib links, supporting clearer onboarding. Demonstrated skills in Cairo programming, Go, concurrent programming, and technical writing, with a focus on cross-repo consistency and maintainability.
May 2026 highlights: Delivered targeted features and API clarifications across erigon and Cairo, driving reliability and developer efficiency. Key features delivered: Fork Choice: Optimistic Store keyed by blockRoot to strengthen optimistic checks and parent-child linking (commit 54e50c18503dbd94b7c88f5b939ab53789aec998). Cairo documentation improvements: WideMul deprecation notes aligned to public API path and direct corelib references (commits 36519e176a2f87d926998ce52c027ddb809bd107, ee60670cfbe135ec9c0ad94dd6c56474cd5a603d). Major bug fix: API error semantics clarified for MethodById and EventByID to reflect actual error returns (commit e10c263e2cb2c29181bc996daf51eaeec3045126). Overall impact: improved fork choice reliability, reduced API misuse, and enhanced onboarding through clearer docs and consistency across repos. Technologies/skills demonstrated: fork choice engineering, API semantics clarification, documentation best practices, and cross-repo coordination.
