AI Projects
IntelBot.ai — Confluence Design Intelligence
IntelBot.ai is a Retrieval-Augmented Generation (RAG) assistant that reads and indexes solution-design documentation from Confluence, retrieves the most relevant context, and provides grounded answers to engineering questions.
It accelerates new-requirement analysis by identifying affected design areas and recommending changes to existing solution designs, reducing manual document review and improving consistency across engineering decisions.
- Context-aware question answering across Confluence design documentation.
- Impact analysis for new business and technical requirements.
- Recommended design updates based on retrieved system context.
R&D · Innovations · PoCs
Single Sign-On between Netcracker & Rakuten E-commerce Portal
Designed and implemented Single Sign-On to give users seamless access across platforms with a single login, using secure token-based authentication and session management. The integration strengthened security, improved the user experience and removed the need for multiple credentials.
Added Multi-Factor Authentication to protect sensitive flows.
Universal Links for Android & iOS
Implemented Universal Links so web URLs open directly in the native app instead of a browser — launching the Rakuten mobile app when installed and gracefully falling back to the browser otherwise, for a consistent cross-device experience.
Content Management System (Portal & Mobile App)
Built a proof of concept for a unified Content Management System to manage email and SMS templates, localizations and carousels for both web and mobile from a single source of truth.
Hackathons & Competitions
WhatsApp E-commerce Onboarding Chatbot
Built a conversational onboarding system on WhatsApp that uses Meta Webhooks to automate customer registration, order processing and support. It enables businesses to onboard users with minimal friction, deliver real-time updates and drive higher engagement.
AI/ML Parking Allotment System
Developed an intelligent parking allotment system that predicts real-time space availability with machine learning and sends instant notifications via Meta Webhooks. The solution optimizes allocation, reduces wait times and improves the user experience through automated updates.
Personal / Independent Projects
Electronic Goods Stock Management with Barcode Scanning
Built a desktop Inventory Management System in JavaFX with integrated barcode scanning to streamline stock tracking, order placement and billing for a retail electronics business.
