Full Stack Developer Intern at Codeflix Labs
Repomind
Internship work: a coursework platform with student, faculty and administrator workflows, PostgreSQL transaction handling and background AI grading. Faculty approve suggested marks. The client repository is private.
- Next.js
- PostgreSQL
- Inngest

The problem
Coursework involves students, faculty, and administrators. Topic assignment and AI-assisted grading need explicit controls.
Implementation decisions
- Use PostgreSQL serializable transactions to prevent competing assignments from overbooking topics.
- Run AI grading and repository synchronization in background jobs with concurrency and rate controls.
- Keep faculty approval between AI-suggested marks and final grading.
Evidence and limits
The product homepage is public and was captured on 21 October 2026. The client repository is private, so source code is not shared here. My internship also included automated tests, deployment checks, backups, and rollback handling; those checks were not rerun for this portfolio update.
