I'm a computer-science student from Vadodara, currently deep in voice — shipping agents that listen, think and answer in under 700 milliseconds on Velox AI, my own B2B platform.

The rest of the time I'm freelancing, over-polishing side projects, and learning to leave things simpler than I found them.

( What I do — 04 )

Capabilities,
carefully kept.

Not your average vibe coder — I build with purpose, plan with precision, and bring structure to every product I touch.

01

Full-Stack Web Development

Complete product builds — considered frontends, dependable backends, and everything wired in between.

02

AI Agents & Voice Interfaces

Agentic workflows, RAG pipelines and real-time voice agents that respond before the silence gets awkward.

03

API Design & Integration

Clean, documented, fast. APIs your future self — and everyone else's — will actually enjoy consuming.

04

Mobile Development

Flutter apps that feel native, move smoothly, and respect small screens as first-class citizens.

05

Deployment & Maintenance

Shipping is the start — cloud setup, CI/CD and the quiet, ongoing care that keeps products healthy.
