Current work

Two projects, both in active development. Nothing here is presented as finished, launched, or revenue-generating.

P.01In development

VetriPOS

Offline-first point of sale for small retail counters — kirana, sweets, groceries. Counter billing with weighed and counted items, hold/resume across restarts, real stock from purchase to sale, and every sale committed in one atomic, audited transaction. Android app plus a transactional Kotlin/Ktor + PostgreSQL backend sharing one domain kernel (712 automated tests green).

  • Gap-free invoice numbering per store, counter and financial year
  • Purchases with weighted-average costing, suppliers, wastage, dues
  • Roadmap: multi-counter sync, scale capture, suggest-only vision

Gaku — Weight CRM

Sales, service and stamping records for weight-scale businesses, with automations around the scale workflow. Ktor + PostgreSQL backend with a Compose Multiplatform client (Wasm and Android) — built for the shop floor, not the back office.

  • Weight-scale sales and service records
  • Stamping-record management
  • Workflow automations

About

Approach

  • Offline-first: the job completes with or without internet
  • Integer money math, audited transactions, no silent failures
  • One shared domain kernel across app and backend
  • Tests before claims — verified beats promised
