What I Build
Three things I build, each tied to something already shipped.
AI & agentic systems
LLM-powered features and agents built into production apps - tool use, structured outputs, and guardrails.
Shipped
Built a Copilot-powered AI agent into the Electron Test Studio at Mozark, cutting test creation by ~2 minutes per user journey.
Full-stack product platforms
End-to-end web and mobile products - UI, backend APIs, and the cloud infrastructure underneath.
Shipped
Architected a no-code enterprise test-automation platform that contributed to a ₹2.5 Cr+ annual ICICI Bank deal.
Automation & developer tooling
Pipelines, test frameworks, and internal tools that make teams faster and releases safer.
Shipped
Replaced Robot Framework/Appium with a CSV-to-Pytest pipeline - 90%+ smaller files and 5s+ faster runs.
Featured Projects
Three products, each with a full case study behind it.

Engineering Philosophy
A few principles I hold to, each earned on a real system.
Own the whole path
The interesting failures hide at the seams - between the interface, the API, and the infrastructure. I work across all three so a feature ships as one coherent thing, not three half-built pieces handed off between people.
Measure before you optimize
Slow is a bug, but guessing at the cause wastes days. I profile first - which is how a mobile app went from 2.5s of navigation lag to under 1s, and a hot query dropped from 11s to about 2s.
Tests are how you move fast
Coverage is not bureaucracy - it is what lets you refactor without holding your breath. On a HITRUST-certified medical-device platform that meant taking unit coverage to 99% before reworking the core.
Put AI where it earns its keep
LLMs are strong at language and shaky the moment you hand them the decision. I use them for explanation, drafting, and structure, and keep the calls that actually matter deterministic and inspectable.
Delete more than you add
The better version of a system is usually smaller than the first one. Replacing a whole test framework with a CSV-to-Pytest pipeline cut file size by more than 90% - less to run, less to maintain, fewer places to break.

Building something ambitious?
