PROFILE
Jakub Zalewski
Jakub worked on the towns-protocol/towns repository, delivering end-to-end MLS-based secure group communication and integrating WebAssembly workflows. He implemented MLS event handling for stream encryption, group management, and external group support, using Go and TypeScript to coordinate backend services and client SDKs. Jakub stabilized WASM packaging by refining build configurations and dependency management, ensuring reliable artifact handling and compatibility upgrades. He improved developer experience by enhancing error messaging and adding user-friendly parameters to the client API. His work also strengthened CI/CD pipelines with better test scaffolding and build reliability, demonstrating depth in cryptography, backend development, and modern build systems.

Jan 1, 2025January 2025 was anchored by delivering end-to-end MLS-based secure group communication capabilities and strengthening the release pipeline. The MLS Protocol Integration and Group Management feature delivered a complete set of MLS event handling in stream encryption, epoch-secret lifecycle, external group support, MLS group service, coordination/queue orchestration, and an MLS adapter for client encryption/decryption. The Client UX Enhancement added a userNickname parameter to the Client constructor, improving debugging clarity. SDK error messaging was improved to accurately reflect dataVersion expectations, reducing confusion in production logs. CI/Build/Test Stability improvements stabilized the WASM CI path, added prettier/vitest support, corrected CGO linking, and introduced test scaffolding for olm.wasm, decreasing flaky tests and build failures. Overall impact: stronger security posture, clearer developer experience, and more reliable, faster releases.

Dec 1, 2024December 2024 — Towns repository focus on WebAssembly integration and wasm-based workflows. Delivered WASM SDK integration with a dependency upgrade and stabilized packaging for wasm-reliant components (stress and playground) by refining build configurations and ensuring correct handling of WASM artifacts. Upgraded the lockfile to mls-rs-wasm 0.0.7 to improve compatibility and performance.
