Over a two-month period, contributed to the sst/opencode and anomalyco/opencode repositories by delivering targeted improvements in developer tooling and code accuracy. Migrated sst/opencode from ruby-lsp to RuboCop, updating server configuration and documentation to enhance Language Server Protocol performance and streamline static analysis using TypeScript and Node.js. This upgrade improved feedback speed and code quality for the team. In anomalyco/opencode, addressed a bug in the CLI’s session statistics aggregation, ensuring accurate inclusion of current-day data by refining cutoff time logic and improving code clarity. Demonstrated a methodical approach to both feature development and bug resolution using TypeScript.
