Backend and systems engineer building reliable software from storage primitives to production platforms.
Bangalore, India · Founding Engineer at SiteSmart India
I design backend and distributed systems that stay understandable under load, failure, and change. My work spans API architecture, realtime collaboration, storage internals, cloud infrastructure, and the observability needed to operate them with confidence.
I currently work as the founding engineer at SiteSmart India, where I built the backend from scratch and helped take the mobile product to general availability. Outside work, I build systems projects, contribute to open source, and write about the engineering tradeoffs I encounter.
Built the serverless FastAPI backend and shipped the React Native product to both app stores. Designed multi-role workflows, authentication, billing, direct-to-S3 uploads, and the PostgreSQL data layer behind daily production use.

Canonical
Added static type annotations across core modules (templater, EC2 source helpers, kernel cmdline net config, user_data, ug_util) as part of the project's incremental typing effort; expands mypy coverage in a codebase that boots instances on every major cloud provider
Python
Added missing return type annotations to the docker stubs across secret, node, and container model operations; improved type-checking accuracy for every downstream project using docker-py

Built a WASM-based sandboxed plugin runtime allowing untrusted plugins to execute under capability isolation; enabled third-party extensibility without granting host system access
SigNoz
Fixed the logs explorer to seed list ordering from the compositeQuery URL parameter, so shared and bookmarked links restore the intended sort; made explorer URLs faithfully reproducible across sessions
