What I'm looking for

I’m looking to build high-performance, secure web experiences with React—shipping AI-enabled features, strong test coverage, and clean code quality practices in a team that values maintainability.

I’m a Senior Software Engineer at Knowledge OutSource, where I implement AI response rendering using streaming Fetch APIs and integrate chatbot functionality into the user interface. I also upgraded React to the latest version, resolved dependency issues, and improved code quality by resolving 95% of SonarQube issues to minimize defects.

Previously, I led React modernization and test upgrades during React 18 migration, using Jest and React Testing Library to build and refactor unit tests with over 80% coverage. I engineered modular, type-safe RTK Query endpoints with TypeScript, resolved 100% of Nexus security vulnerabilities, and supported production stability through careful refactoring, accessibility updates, and reliable UI component development.
