## Overview

A sales and stock-tracking program I built for Otoeko in my first year of university, as a job offer. The goal was to let small businesses sell quickly and keep stock on a single computer.

## Solution & Architecture

The interesting constraint: I used no database engine (no SQL/SQLite) — all data was kept in a file-based (XML) structure. Even so, I delivered product cards, stock in/out, stock-movement history, advanced search/filter, barcode, PDF/print reports, FTP sync and backup, with a layered architecture (UI / business logic / data access).

## Outputs & The Constraints of the Time

The result was a comprehensive, self-contained sales/stock program needing no installation and no external database server. Building a stable architecture carrying this many features without a database engine — with the means of a first-year student — was a meaningful step in problem-solving.
