Enterprise Knowledge Retrieval & RAG Pipeline

Private Hybrid Vector Retrieval with Verified Source Citations

A private Retrieval-Augmented Generation (RAG) system with hybrid dense-sparse vector search, enabling staff to query technical documentation and operational policies with cited sources.

The Architectural Challenge

Internal support and operations staff spent hours searching through fragmented documentation across PDFs, Notion, and internal databases, causing delayed ticket response times and inconsistent answers.

Qualitative Outcome

Streamlined internal knowledge discovery, reduced repetitive tier-1 support queries, and ensured private enterprise data isolation without model retraining.

Headless Next.js Travel & Booking Architecture

High-Performance Multi-Currency Reservation & Checkout Engine

A decoupled travel booking storefront with real-time inventory aggregation, dynamic fare caching, and streamlined multi-currency checkout.

The Architectural Challenge

Legacy monolithic booking software suffered from slow search response times, cart drop-offs, and checkout latency during peak seasonal booking campaigns.

Qualitative Outcome

Delivered fast page transitions, improved booking conversion flows, and eliminated checkout latency during peak traffic periods.

Real-Time Telematics & Fleet Dispatch System

High-Concurrency WebSocket Ingestion & Driver Coordination

A high-throughput WebSocket telematics platform processing live GPS telemetry for regional dispatch coordinators and operations teams.

The Architectural Challenge

Dispatch coordinators struggled with delayed vehicle location updates and manual route scheduling errors, leading to delivery bottlenecks and customer uncertainty.

Qualitative Outcome

Delivered live fleet tracking, automated route deviation alerts, and unified dispatch coordination across operational teams.
