Project history
Backend services development using Java, Python, Nest.js, and Node.js. Angular frontend development, Jenkins automations, GitLab/Azure DevOps CI/CD, Socket.io and Kafka communication, database management with PostgreSQL, MS SQL Server, InfluxDB, and Redis, as well as Kubernetes/Rancher/Docker infrastructure management.
Founder and director of the company. Partnership with Serbian companies in chain to Aptar Global.
Managed MES resources across multiple clients, deployed and debugged MES Edge systems on Raspberry Pi 4 devices, debugged OPC communication with PLC machines, managed Kubernetes and k3s clusters using Rancher, performed application migration from legacy to modern systems in Angular/Java, set up custom OS for Raspberry Pi 4, used Ansible for mass-scale commands, debugged Kafka/Redis systems, and developed Python/Node.js backend and Angular frontend.
