PROFILE

Mahdi

Over a three-month period, contributed to both frontend and backend blockchain projects, focusing on authentication, security, and observability. Developed Unicorn Wallet integration for user authentication in the ens-app-v3 repository, expanding login options and updating dependencies using React and TypeScript. In the Giveth/impact-graph repository, enhanced deployment reliability by implementing CORS whitelisting, health check endpoints, and enriched status diagnostics with Express.js and TypeScript. Explored account abstraction for donation verification across smart contract wallets, refactoring transaction services for token-agnostic support. Additionally, introduced EVM transaction tracing breadcrumbs to improve debugging and monitoring of transaction flows, strengthening reliability and traceability in Ethereum-based systems.

April 2026 performance summary for Giveth/giveth-dapps-v2 focused on delivering user-centric UX improvements, strengthening security hygiene, and overhauling data retrieval and UI with a GraphQL-driven approach. Key outcomes include a robust donation link loading and error state, hardening of environment variable handling by removing sensitive vars and updating gitignore, and a comprehensive QF system overhaul that refactors data structures, updates GraphQL queries, and aligns UI with new design, including deprecation of outdated tests. These efforts deliver tangible business value: smoother donation experience, reduced risk in version control, faster and more reliable data access, and a cleaner, scalable frontend.

January 2026 performance for Giveth/impact-graph focused on security, deployment reliability, and experimentation with Account Abstraction (AA) donation verification. Key improvements include CORS whitelisting and health check enhancements for the base mini app, plus health/status enrichment to verify deployments and security. AA donation verification experiments (ERC20 and native token support) were explored with a refactor to the transaction service; some iterations were rolled back to preserve stability. Overall impact: stronger host management, better deployment visibility, and a clear path toward token-agnostic donation verification across smart wallets. Technologies demonstrated include CORS policies, health checks, hostname management, and smart-contract wallet integration patterns.
