ZeroEntry.

AI invoice automation for SMBs.

Turned invoice processing from hours of typing into minutes of review for 5 SMB vendors in Pune. Email pipeline auto-ingests invoices; OCR + LLMs extract structured data with confidence scoring; low-confidence cases route to a human queue; cleared records post to Zoho Books automatically. Bank-statement parsing closes the loop.

MedOS.

A 36-module HMS for Indian district hospitals.

Targets the gap between hospitals too small for enterprise HMS and too complex for spreadsheets — 30–200 bed district hospitals. 36 interconnected modules from OPD to MIS, built to NABH and ABDM (ABHA ID) specs, with operator-first UX for non-technical staff. Cross-module flows eliminate double-entry.

Technology Partner

at NVSX Electronics LLP

Pune · Remote-first

Own the technology stack for a profitable authorized distributor of AMD, ASUS, Intel, NVIDIA, MSI, Corsair, Lian Li, and Razer. Built nvsx.in from scratch on Next.js; integrated Claude agents that run store operations through natural language; shipped a 6-rule PC Builder compatibility engine and a deep Zoho Books sync. Live revenue flows through code I wrote.

VendorPaymentSystem

Owned payment flow components across Processing, Authorization, and Payment on a service moving multi-million-dollar daily volume at a 99.99% uptime SLA. Built validation, retry logic, and idempotency for the edge cases that would otherwise wake up oncall.

InvoiceIngestionTeam

Kept ingestion, enrichment, and validation pipelines running across millions of vendor invoices per year — multiple currencies, formats, compliance regimes. Hardened enrichment to cut downstream payment errors before they reached ledgers.

SubmitInvoiceService

Unified email, API, and portal submission behind a single normalization layer. Reduced submission errors; turned adding new channels into a config change instead of a service rewrite.

Data Comparator

Shipped the deterministic diffing tool that became the finance org's standard migration-safety check — caught the data issues migrations wanted to hide.

Invoice Matching

Rules-and-heuristics engine linking POs, invoices, vendors, and payments — handled partial matches, split payments, multi-PO, currency. Cut the manual reconciliation workload significantly.
