Robson Idongesit Samuel

Backend Engineer with hands on experience designing and shipping production grade REST APIs using Node.js, TypeScript, and Nest JS. Specialises in monolith/microservice architecture, third party payment integration (Paystack, Flutterwave), and authentication systems (JWT/OAuth/RBAC). Comfortable across the full backend lifecycle from schema design and business logic through to Dockerised deployment and code review, with a track record of building resilient, well tested services in collaborative team environments.

Software Developer (NYSC) at Casafina Development (2026-01 – Present)

• Contributed to database schema design and API development across multiple internal services, translating product requirements into clean versioned RESTful endpoints.
• Implemented DTO validation, business logic layers, and full authentication workflows using JWT and OAuth, ensuring consistent input sanitisation and access control across services.
• Actively participated in sprint planning, code reviews, and debugging sessions, improving team velocity and maintaining code quality in a Git-based collaborative workflow.
• Documented API contracts using Swagger/OpenAPI, reducing integration friction for frontend and QA teams.

Backend Engineer (Volunteer) at Travel & Tours Platform (2024-11 – 2025-12)

• Designed and shipped hotel booking, accommodation listing, and vendor management APIs serving as core features of a production travel platform used by early-access travellers and hotel partners.
• Integrated third party hotel search and availability APIs, handling data normalisation and error resilience patterns (retries, circuit breaker logic) to handle upstream instability.
• Built end to end Paystack payment flows including webhook handling, payment verification and reconciliation logic, reducing failed transaction edge cases by standardising webhook event processing.
• Implemented JWT based authentication with RBAC supporting three distinct user roles: travellers, vendors, and admins with scoped permissions across all endpoints.
• Collaborated within a backend team practising Git branching, pull request reviews and iterative API design aligned to evolving product requirements.
