Tobias Lins

Worked on the garden-co/jazz repository, delivering features and fixes across front-end and back-end systems over seven months. Built configurable multi-storage persistence for jazz-browser, integrating IndexedDB and singleTabOPFS with centralized logic and unit tests to improve data durability. Refactored chat UI and messaging flows in React Native, introduced persistent SQLite storage, and enhanced authentication storage with secure, flexible key-value management. Improved developer experience by resolving configuration and analytics tracking issues in Next.js and TypeScript. Led major UI and performance overhauls for the Inspector tool, optimized query subscriptions using Rust, and implemented benchmarking to reduce server load and improve reliability.

May 2026 monthly summary for garden-co/jazz: Delivered the Query Subscriptions Performance and Visibility Recompute Optimization feature, including a benchmarking suite for server authorization scope, to reduce redundant checks, determine when visibility recomputation is required, and mark subscriptions for recomputation under specific conditions. Implemented fixes for correctness and stability: avoided duplicate server scope authorization, skipped unnecessary clean subscription settling, and invalidated clean subscriptions on scope changes. Business impact: improved query subscription throughput and visibility accuracy, reduced server load under scope transitions, and more reliable subscription lifecycle processing. Technologies/skills demonstrated: benchmarking design, performance optimization for server authorization scopes, conditional recomputation logic, and subscription lifecycle improvements.
