Context
The platform was built for RA-ATAP Telkom University to digitize participant registration, document review, and enrollment workflows previously handled through fragmented manual processes.
Primary users include non-technical administrators, requiring deterministic system behavior, strict validation rules, and full traceability of all training hours.
Core Constraints
- 100% computational accuracy for training hours accumulation to ensure compliance with CASR Part 147 regulations.
- Complete auditability of participant identity, document versions, and certification state transitions.
- Sub-30 second financial verification latency through real-time Payment Gateway integration.
- Strict relational integrity across multi-stage workflows, including automated logbook and digital certificate issuance.
Key Design Decisions
A Decoupled N-Tier Architecture was implemented using Laravel (Backend API) and Next.js (Frontend) to separate business logic from presentation.
Workflows were explicitly modeled as state machines and enforced at the database layer (PostgreSQL) to prevent bypass validation.
Third-party integration (Midtrans, Google OAuth, Resend) was delegated via secure APIs and webhooks to minimize internal overhead.
Trade-offs
Prioritizing relational correctness and a 'Single Audit Phase' increased upfront effort but eliminated operational ambiguity and manual coordination.
Outcome
Manual, spreadsheet-driven processes were replaced with a structured digital ecosystem, reducing manual coordination by over 90%.
