SAP B1 Integration Engineer at Business Intelligence Solutions connecting POS, manufacturing, payment, and ERP systems.

Uzbekistan

Message

At Business Intelligence Solutions, I build integrations between SAP Business One and external systems, including Mdokon POS, manufacturing equipment, and Smartup ERP. I use Node.js and TypeScript middleware when SAP’s native interface is too complex.

I built and maintained the NestJS REST API for DachaBook, a rental marketplace connecting property owners with guests. It supported the web platform, mobile apps, owner portal, and admin panel, with PostgreSQL, Redis, and S3.

At DeepRed, I architected and developed an Express.js and TypeScript backend for a social platform connecting influencers, sponsors, and entrepreneurs. I implemented real-time messaging with Socket.IO and payment workflows with Stripe Connect.

I’ve also worked as a Frontend Web Developer at Bron24, a Software Engineer at OPEN CLOUD JV LLC, and a Frontend Developer at TEDA LLC. My experience spans enterprise ERP integrations and full-stack products using tools such as React, Next.js, and PostgreSQL.
