The primary goal of software engineering is to build rigorous business logic that prevents data discrepancies and aligns perfectly with real-world operations.

Mohamed Elborno·Product-Focused Full Stack Engineer | Erzurum, Turkey

01

My practical experience lies in building custom business operations solutions. This includes engineering sales and invoicing engines that handle millions of SAR in monthly transaction flows while automatically integrating them with accounting journals, alongside real-time AI processing pipelines operating across 7 different languages.

02

My expertise covers developing core ERP and supply chain modules, such as sales and procurement lifecycles, warehouse movement management, and building SaaS architectures. I take technical ownership of the product lifecycle from designing APIs and database schemas to frontend development and production deployment.

03

Whether the challenge involves engineering intermediary credit ledgers to track balances and debit/credit movements with clear reference paths, or designing logistics workflows that handle stock validation and reservation prior to actual deduction; my ultimate goal is to bridge the gap between real business needs and deployed technical solutions.

Developing the Sales Lifecycle and Logistics for a Steel Manufacturing ERP

internal.erp.sa/dashboard

A Saudi company with a massive transaction volume required strict automation to bridge accounting and logistics, eliminating discrepancies among financial receipts, customer credit balances, and live warehouse inventory deductions.

I built and developed the end-to-end quotation and receipt system, engineering an integrated business logic that links invoices, receipts, and delivery orders directly to the general ledger for real-time transaction posting. I designed an intermediary credit ledger (Log) to document credit details and established an invoicing structure ready for regulatory compliance.

A fully integrated, production-stable operational lifecycle ensuring absolute automated synchronization between field operations and the accounting general ledger, coupled with flexible credit and warehouse management, and zero discrepancies in live balances.

Separating sensitive financial data from the logistics module while maintaining workflow cohesion; ensuring no delivery order is processed without automated stock validation, and preventing actual stock deduction until confirmed by the warehouse keeper.
