Worked on the Apify stack to deliver configurable resource controls and enhanced proxy targeting, focusing on reliability and customer-specific needs. Developed features in apify-shared-js to allow dynamic Actor memory allocation with schema validation and security updates using JavaScript and TypeScript. Extended apify-sdk-js and apify-sdk-python to support US state-level proxy targeting, adding subdivision code parameters and updating validation logic. Improved documentation in apify-docs to clarify SDK proxy configuration, reducing misconfigurations and support requests. Emphasized API development, backend integration, and dependency management, ensuring that new features were well-documented, secure, and aligned with business requirements for performance and usability.
