During March 2026, Ufuk Altinok developed and stabilized customer-facing features across sst/opencode and Kilo-Org/kilocode repositories. He implemented session-level caching in React and TypeScript to persist question dock state, ensuring users’ progress and custom inputs were reliably restored across session switches. In parallel, he addressed token accounting accuracy after an AI SDK upgrade, resolving double-counting issues for anthropic and bedrock providers and updating tests to reflect the new logic. His work demonstrated a full stack approach, combining front end development with robust testing practices, and contributed to more reliable AI integrations and improved user experience through reduced friction and accurate cost tracking.
