Blessy Korah

I've built and shipped production-grade systems across AI document intelligence, quantity takeoff, hotel management, ERP, and CAD automation. At Spice Technologies, I lead architecture, implementation, performance optimisation, and support for a live PDF-based estimation platform used in AEC workflows.

I designed modular measurement libraries backed by SQLite, async PDF loaders with concurrency controls, and a C++ snapping integration that improves measurement accuracy. I also delivered secure licence validation with caching and webhook verification.

At Armada Infotech, I built reservations, housekeeping, billing, and multi-property operations for a hotel management system, including Booking.com and Agoda integrations through RateTiger APIs. I've also led zero-downtime data migration, improved SQL performance, and delivered finance, contracting, payroll, dashboards, and operational reports.

I'm transitioning deeper into AI/ML and generative AI engineering through hands-on RAG, LLM, and agentic workflow projects using Python, FastAPI, LangChain, pgvector, ChromaDB, and FAISS. My portfolio includes an AI Document Intelligence Platform, a Job Application AI Copilot, and an in-progress IFC-to-RAG knowledge base for querying BIM models.
