Selman Altinay

I'm Selman Altinay, a Belgium-based software engineer (Rui Codex, Tielt-Winge) with 12+ years of experience building business software end to end: web applications and APIs in C#/ASP.NET Core with PostgreSQL or SQL Server, and integrations between systems that don't talk to each other. On Odoo I offer custom modules, configuration, data migration, version upgrades and external integrations, including moving existing integrations from XML-RPC/JSON-RPC to the new JSON-2 API. Delivered integration work includes a modular web ERP (purchasing, sales, export, finance, warehouse), real-time sync between marketplaces (Trendyol, Hepsiburada, N11) and Netsis accounting with automated e-invoices and e-waybills, and a PrestaShop pipeline to accounting and four carriers. Case studies: https://ruicodex.com/CaseStudies I work async-first in writing (English, Turkish, basic Dutch), in short milestones with a written estimate before each task. Work done inside your own Odoo (custom modules and configuration) stays in your system as source code you can use and modify.
