PROFILE
Sam Parhimchik
Over a three-month period, contributed to the orca-so/whirlpools repository by delivering four new features focused on Solana transaction tooling and developer experience. Developed and released both a TypeScript-based public tx-sender package and a Rust crate for efficient Solana transaction management, supporting priority fees, Jito tips, lookup tables, and compute unit estimation. Enhanced the Whirlpools SDK with new actions and improved documentation, while also introducing a non-breaking API extension to streamline token account creation. Emphasized API design, async programming, and SDK development using JavaScript, Rust, and TypeScript, prioritizing feature delivery, stability, and integration readiness without major bug fixes.

Dec 1, 2025December 2025: Delivered a non-breaking API enhancement to the Whirlpool Client by introducing an optional resolveATA parameter to enable automatic creation of associated token accounts when needed during openPositionWithMetadata. This streamlined user workflows, reduced setup friction, and improves onboarding for new users. The change is implemented as a nonbreaking param extension with a single commit (9d7e56da10bb951bd7603bf14303664d3de2e252 -> whirlpoolClient nonbreaking param extension (#1202)).

Mar 1, 2025March 2025: Key deliveries focused on developer-facing enhancements and robust transaction tooling for orca-so/whirlpools. Key features delivered include the Whirlpools SDK Actions feature (integration into the SDK, with refactor, docs, and dependencies updates) and the new orca_tx_sender crate for Solana transactions (dynamic priority fees, Jito tips, compute unit estimation, retries, and global configuration). Major bugs fixed: no explicit major bugs fixed documented this month; stability improvements were achieved via SDK refactor and improved error handling in transaction flows. Overall impact: faster time-to-value for integrations, improved protocol interaction, and more reliable transaction processing. Technologies/skills demonstrated: Rust, Solana, SDK design and refactor, dynamic fees and retries, compute unit estimation, config management, and comprehensive documentation.

Feb 1, 2025February 2025 monthly summary for the whirlpool lineage highlights the delivery of a public Solana tx-sender package in the orca-so/whirlpools repo. The @orca-so/tx-sender public package enables efficient construction and sending of Solana transactions with support for priority fees, Jito tips, and lookup tables for transaction compression. It is implemented in TypeScript and uses @solana/web3.js v2.0. The change is backed by commit a3b78879ff3aae4e0528f547a0efd4c76eddcdac (#667). This work drives business value by enabling faster, cheaper transactions for downstream apps and liquidity providers, while improving developer experience and package usability. No high-severity bugs were fixed this period, with focus on feature delivery, stability improvements, and enabling downstream integrations. Technologies demonstrated include TypeScript, @solana/web3.js v2.0, and public API design for a reusable transaction sender package.
