About

01

I'm a software developer with roughly two years building production systems on the MERN stack, alongside backend work in Python. Most of my time is spent on the seam between infrastructure and product: designing schemas and REST APIs that hold up under real usage, then wiring in cloud services and AI-driven automation on top. I did my Integrated B.Tech + MBA in Information Technology at ABV-IIITM Gwalior, and outside of client work I keep building tools that remove a specific, annoying piece of manual work — from government paperwork to phone calls.

Featured Projects

A pattern runs through most of these: find the most repetitive, manual part of a workflow, and build a system that removes the human from the loop.

SIMVox-AI (CallVox AI)

Open Source

An autonomous AI voice agent that turns any Android phone into a real cellular receptionist — no Twilio, no VoIP fees, no SIP trunks. It bridges a PC straight to an Android handset over ADB and real hardware audio channels, routes live call audio through Google Gemini for reasoning and Microsoft Edge neural TTS for sub-second, natural-sounding replies, and auto-answers or places outbound calls entirely on its own — with a glassmorphic desktop dashboard showing live waveforms, transcripts, and a searchable call CRM.

Mr. Proper — Loyalty, CRM & ERP Platform

Live

A full-stack operations platform for Mr. Proper's painter and contractor network — not just a customer-facing loyalty app, but a real backend management system underneath it. It runs a CRM for tracking contractor relationships, an ERP-style layer for coupon inventory, order processing and redemption tracking, and role-based dashboards so admins, distributors, and painters each see only what's relevant to them.

Magra Tender Automation Panel

Private

Probably the clearest example of how I like to automate: government tender paperwork is slow and repetitive, so this turns "enter the tender details once" into a full document pipeline — auto-generating the public tender notice, quotations, supply orders, and firm bills, each rendered onto a firm-specific letterhead with a print-precise A4 layout engine. An AI drafting layer (with automatic fallback across four providers) writes procurement-grade language in Hindi or English, and every edit is versioned.
