Problem: Users needed multiple tools/apps to convert, merge, compress, and secure files — creating friction and privacy concerns with uploading to random services.

Approach: Built a universal converter supporting PNG/JPG/WEBP ↔ PDF/DOCX with AI-assisted watermark removal, PDF-to-Excel table extraction, merge/split, 256-bit AES encryption, and audio/video conversion with codec control.

Role: Full-stack development — designed the architecture, built frontend and backend, and implemented Supabase auth for free/pro tiers.

Impact: Single platform replacing 5+ separate tools; zero file uploads to third-party servers.

Problem: Colleges handled No Due Certificates manually — students physically visited 6+ departments, waited days for signatures, and payments were tracked on paper.

Approach: Built a multi-stage clearance workflow (Faculty → AICTE → Librarian → Accounts → HOD → Principal) with HDFC SmartGateway payment integration, webhook verification, and bulk CSV imports.

Role: Full-stack development — designed role-based access across 12+ roles, multi-tenant architecture with per-institution branding and billing plans.

Impact: Digitized an entirely manual clearance process; adopted institution-wide at MIT Mysore.

Problem: Engineering colleges managed admissions, assessments, exams, and results across disconnected spreadsheets with zero audit trail or access control.

Approach: Built a 10-role RBAC hierarchy with OWN/ASSIGNED/DEPARTMENT/ALL scopes. Full academic structure: departments, programs, courses, batches, semesters. Separation-of-duties workflow (clerk entry → COE approval → admin publish).

Role: Full-stack architect — designed zero-trust security model, immutable audit logging, and the complete role hierarchy.

Impact: Covers the full academic lifecycle from admissions to result publication with immutable compliance.
