Project History
Touch-free Access App
https://github.com/harsha09/face_detectionAn application designed for touch-free access for employees in co-working spaces. I've built a face recognition and verification service using FastAPI which successfully verifies and authenticates a person for access. Worked on liveness detection of a person to verify accordingly.
BA.ai
This tool is built using Python, LangChain, VectorDB, and LLMs.
Built feature generator, BRD generator, Jira stories generator with estimation.
I implemented the RAG architecture to create a chatbot to chat with the project artifacts. I also enabled the generation of answers to technical questions based on project and external data.

Structured Vibe Coding Tool
https://harsha09.github.io/spec-driven-development/guides/simple-featureSpec-driven development, built for the enterprise.
Spec-driven development (SDD) makes specifications the source of truth, where you define what to build and why, and AI agents handle the how, with verification at every step. But almost every SDD tool available today is optimized for greenfield projects and solo workflows, and they break down when applied to enterprise-grade systems with established governance, multiple teams, and brownfield codebases.
Structured Vibe Coding CLI was built from a study of the common problems organizations face when adopting SDD tools. The result is a CLI that offers customizable workflows tailored to your organization's needs, so spec-driven development fits into your delivery process rather than requiring you to rebuild it.
Install: npm install -g @structured-vibe-coding/cli
