I have experience building software solutions for manufacturing and logistics in the automotive and food industries. I develop WMS and production systems with real-time inventory visibility, barcode-driven shop floor operations, and role-based workflows using Vue.js, .NET, Android, and SQL Server. I also contributed to pull-based (JIT) production logic to improve replenishment, reduce inventory, and increase responsiveness. Additionally, I worked on MES design tools (C#/.NET, WPF) and production order queue management systems to improve planning, prioritization, and traceability. Previously, I spent several years in the gaming industry developing browser-based interactive slot games, focusing on smooth UI performance, animations, and consistent UX across desktop and mobile.

Project history

Digital Pull System

Automotive industry

Industry & Mechanical Engineering

500-1000 team member

Worked on a pull-based production workflow where manufacturing is triggered by actual customer demand instead of forecasts. Helped design and implement the logic for just-in-time replenishment of materials/WIP to production lines, reducing inventory and minimizing overproduction. Integrated real-time demand tracking and analytics to dynamically update production priorities and improve responsiveness on the shop floor.

Process Optimization for a production warehouse

Automotive industry

Industry & Mechanical Engineering

500-1000 team member

Warehouse Management System (WMS) with an Android mobile app. Built a web dashboard in Vue.js and backend services in .NET, enabling real-time inventory visibility, stock movements (receipts/issues), and barcode-based operations on the shop floor. Improved stock accuracy, reduced manual paperwork, and accelerated order picking through faster, error-resistant workflows and role-based access.

MES design tool

Food industry

Industry & Mechanical Engineering

500-1000 team member

Desktop application supporting the design and configuration of MES solutions for manufacturing (process modeling, data structures, and system setup). Built in C# (.NET) + WPF with SQL Server for persistence; involved in implementing UI views (MVVM), business logic, and database integration (queries, data models).

Production Queue modernization

Food industry

Industry & Mechanical Engineering

500-1000 team member

Production Order Queue Management system. Delivered a Vue.js web app with a .NET backend to manage and prioritize the manufacturing order queue, giving teams real-time visibility into what should be produced next. Improved planning and workload balancing, reduced confusion on the shop floor, and shortened lead times through clear statuses, priorities, and audit-friendly tracking.
