Solution Overview & Operational Bottleneck
An education and learning management architecture engineered for vocational academies, corporate training institutes, and coaching schools. Unifies curriculum delivery, assignment submissions, quiz evaluations, and verifiable digital certificate issuance.
Instructors spend hours sharing Zoom links via WhatsApp, grading student assignments in disorganized email threads, and manually creating certificate PDFs. Student records and minor personal data are carelessly handled across disparate cloud tools.

Requires cohort enrollment reports, tuition tracking, and certification authenticity.
Instructor / Trainer
Needs clean curriculum module publishing, assignment grading, and attendance rosters.
Student / Learner
Wants structured syllabus navigation, video lessons, quiz feedback, and earned certificates.
Parent / Guardian
Requires visibility into minor student attendance, progress, and fee receipts.

Definition of Done & Verifiable Acceptance Criteria
Deployment Host, Database Isolation & Maintenance
Cloud container hosting (AWS ECS / Cloud Run / DigitalOcean App Platform).
PostgreSQL instance with cohort-level role security; private S3 bucket for student files.
Daily automated database snapshots with 30-day retention.
Monthly security patch updates, term-end student archive and export maintenance.
Project Risks, Mitigations & Ownership
Mitigation: Limit active sessions to 2 concurrent devices per student account.
Mitigation: Strict file extension allowlist (.pdf, .docx, .zip) and MIME type validation before saving.
Mitigation: Certificates explicitly state they represent institutional completion, not statutory degrees.
