AgentDesk: AI Customer Support Platform

RAG Support Platform with Document Ingestion, Semantic Search & Cited Answers

Problem Context

Customer support teams spend hours answering repetitive inquiries across disconnected documentation, leading to slow response times and error-prone manual lookups.

What I Engineered

Built an autonomous document ingestion pipeline that extracts, chunks, and embeds text into pgvector for semantic search, powered by BullMQ background queues with cited source responses.

Attendance Management System

Event Check-in Platform with QR Lifecycle Management & Real-Time Analytics

Problem Context

Managing attendance for frequent university events with paper rosters or unverified forms caused congestion, duplicate submissions, and lacked real-time visibility.

What I Engineered

Designed a fullstack attendance engine with QR-code and manual check-in workflows, JWT authentication, Brevo email alerts, and live participation analytics.

Charity Management System

3-Role Donation Platform with Chapa Webhook Verification & Automated Receipts

Problem Context

Charitable donation platforms often struggle with donor transparency, fraudulent charity verification, and manual, error-prone payment receipting.

What I Engineered

Architected a secure 3-role platform with cryptographic Chapa webhook verification, automated PDF donation receipts, Multer document validation, and Recharts analytics.
