April 2025 (Effect-TS/effect) delivered two core capabilities and notable quality improvements. Key features delivered: RPC Middleware with TimingMiddleware to enable interception of RPC execution and to collect metrics (success, defect, count). Code quality enhancements through ESLint plugin integration (@effect/eslint-plugin) and enabling no-import-from-barrel, plus a safe integer constant refactor in SqliteClient.ts. Major bugs fixed: none reported this month; overall impact: improved observability, reliability, and maintainability enabling faster diagnosis and safer future changes. Technologies/skills demonstrated: TypeScript, middleware architecture patterns, ESLint tooling, code refactoring, and lint-driven quality practices.
