Worked on the lidofinance/ethereum-staking-widget repository to deliver comprehensive Content-Security-Policy enforcement across all pages, focusing on security hardening and configuration maintainability. Refactored the Next.js configuration in next.config.mjs to unify cache-control and CSP verification lists, ensuring consistent security policies throughout the application. Implemented automated tests using JavaScript and TypeScript to verify the presence of CSP headers in enforced mode, reducing the risk of misconfigurations and improving predictability across environments. The work emphasized front end development, security best practices, and robust testing, resulting in a more secure and maintainable codebase without introducing user-facing bug fixes during the period.
April 2026 (lidofinance/ethereum-staking-widget): Key security features delivered and tested. Implemented Content-Security-Policy enforcement across all pages and refactored security configuration to unify the cache-control and CSP verification lists in next.config.mjs. Added automated tests to ensure the CSP header is present in enforced mode on every page (commit d079b54dc949d388d1a2e1721569ae94ae206318). No critical bug fixes were deployed this month; primary focus was security hardening and configuration maintainability. Business impact: reduced risk of CSP misconfigurations, improved security posture, and more predictable page behavior across environments. Technologies demonstrated: Next.js configuration (next.config.mjs), CSP policies, automated testing, and cross-functional collaboration.
