Hackathon Outcome

1st Place Champion

01. The Problem & Challenge

The Problem & Real-World Friction

Citizens in municipal areas face severe communication friction when reporting civic issues in mixed Banglish/English. City authorities lack automated triage tools, resulting in backlogs, missed emergencies, duplicate complaints, and exposed citizen PII.

02. The Engineered Solution

Architectural & Technical Approach

Architected an end-to-end civic reporting platform with multimodal LLM classification (Banglish & English), automated severity categorization, resilient Gemini primary / Groq fallback failover, Supabase Row Level Security for strict PII isolation, and multi-signal duplicate detection combining semantic text embeddings, geospatial proximity (PostGIS), and temporal windows.

03. Core Capabilities Breakdown

Key Technical Highlights

Multimodal AI Municipal Triage System

Banglish & English AI Triage

Multimodal LLM pipeline classifying municipal citizen reports in conversational Banglish and formal English with automatic priority severity scoring.

Zero PII Citizen Privacy

Strict privacy safeguards with Supabase Row Level Security (RLS) guaranteeing that personal identifying data is never exposed in public triage feeds.

Multi-Signal Duplicate Detection

Combines semantic vector embeddings (pgvector) with geospatial proximity and temporal clustering to eliminate duplicate municipal work tickets.

Resilient Dual-AI Failover

Dual LLM provider pipeline with Google Gemini as primary inference engine and Groq / Llama as automatic, zero-downtime failover fallback.

04. Measured Outcome & Impact

Project Results & Impact

Won 1st Place Champion at AI & API Hackathon 2026 – First Edition (IEEE CS SEU). Reduced complaint triage time from hours to seconds.
