PROFILE

Worked on the DFXswiss/api repository to enhance backend API capabilities, focusing on user onboarding and regulatory compliance. Delivered features such as exposing user capabilities with clear status indicators and refining KYC workflow routing to reduce client-side logic duplication. Emphasized data integrity by preserving UTF-8 umlauts and enforcing the Swiss payment character set through custom validation. Maintained backward compatibility and ensured all changes passed a comprehensive test suite. Utilized TypeScript for backend development, applying robust DTO design and validation patterns. Collaborated on API surface improvements, prioritizing clear documentation, stable integration points, and strong test-driven development practices throughout the project.

May 1, 2026May 2026 monthly summary for DFXswiss/api: Overview: - Focused on API surface improvements, KYC routing clarity, and data integrity aligned with regulatory requirements. Delivered backend DTOs and client-facing indicators to reduce UI branching, while maintaining backwards compatibility and strong test coverage. Key features delivered: - User Capabilities API and Support Accessibility • Exposed UserCapabilitiesDto via /v2/user with per-action capabilities and introduced ALREADY_REGISTERED status to distinguish merge/retry flows. Removed supportAvailable flag to standardize accessibility across onboarding states. Co-authored changes recollecting realunit-app decision authority. Commits: 2b667d97febe2546c64b5ec325b5e2fc432488c9; 0fdd52d89109d1f3bba7bb5afd7113d36621ad4a. - KYC Workflow Routing and Status Indicators • Added routing signals in KYC: isRequired, processStatus, and canTrade semantics exposed to clients to stop local routing re-implementation. Mapper updates across KYC DTOs with tests confirming new paths. Commit: 479bd59c73763b99e594a27e533306043da8abcf. - Data Integrity and Swiss Compliance for User Data • Preserved UTF-8 umlauts in user data; restricted personal fields to the Swiss payment character set with a new @IsSwissPaymentText validator. Ensured backward compatibility by not re-validating existing rows. Commit: d87b92b87ed2478f35068c537027ea95d9b9b2a1. Major bugs fixed: - Structured ALREADY_REGISTERED as a valid status and harmonized HTTP status handling so retries are cleanly distinguishable from generic 400s (avoiding misinterpretation, event-driven UI flows). 201 status preserved for completed-already-registered scenarios. - Removed obsolete supportAvailable gating from UserCapabilitiesDto to prevent pre-signin onboarding blocks. Overall impact and accomplishments: - Business value: Reduced client-side logic duplication, faster onboarding, and clearer decision points for the frontend. Users experience more consistent capability visibility and a smoother registration flow, even when wallet/address states vary. - Technical impact: Clear API surface with stable and extensible DTOs, improved KYC routing semantics, and stronger data quality and regulatory alignment for personal data. - Quality: End-to-end test suite remains at 943/943 passing after changes; CI and lint/type-check passes ensured. Technologies and skills demonstrated: - Backend DTO design and API surface refinement; robust type-safe mappings in realunit-app integration (KYC and user data DTOs). - Validation patterns and localization considerations (IsSwissPaymentText validator; UTF-8 handling). - Test-driven changes with regression coverage and CI hygiene; cross-repo coordination on API authority planning (Wave references). - Collaboration and code quality: Co-authored fixes and clear documentation in commit messages; maintained backward compatibility and aliasing through additive changes.
