Building Mira: a voice front-desk in 48 hours
A weekend rabbit hole. Switching mid-build from LiveKit + Deepgram + Cartesia to Tavus CVI, the seven booking tools, and the bugs that taught me the system.

Software Development Engineer I at House Works Technology · Remote (India)
I own backend architecture and infrastructure end to end on a HIPAA-aligned multi-tenant healthcare SaaS. I led a greenfield authentication and authorization platform from architecture through production deployment: self-hosted Keycloak with custom Java SPIs, multi-tenant SSO with IdP federation, and SpiceDB-based ReBAC. On my own time I build voice and agentic AI projects like Mira and Fieldnotes.

What I work with
Backend & APIs
Python, Django, FastAPI, and PostgreSQL — auth, data modeling, and APIs built to hold up in production.
Applied AI & Agents
LLM applications, RAG pipelines, and tool-calling agents — wiring models into products that do real work.
Infrastructure & Cloud
Terraform and Docker on AWS, plus a k3s homelab on OCI — reproducible infra and CI/CD from zero.
Why this site exists
I learn things by building the smallest version that actually runs, then writing down what broke. This site is where both halves end up — the projects and the post-mortems. If it saves you an afternoon, even better.
Playground
Not everything needs to be a product. These run in your browser right now.
The Wall
A shared 64x64 canvas. One pixel per visitor every ten minutes.
Earth Observatory
A 3D globe of live wildfires and storms, straight from NASA’s EONET feed.
