About Me.

A brief introduction

I am a software engineer and electrical engineering graduate currently pursuing an MSc in Computational Engineering at FAU Erlangen-Nürnberg, with 3+ years of experience across backend development, AI, telecom, and hardware-related systems. I work with Python/Django, Node.js, Flutter, React/Vue.js, Laravel, and DevOps/security tools to build secure, scalable applications, including mobile apps, ERP systems, Shopify plugins, LLM/RAG solutions, and network dashboards for international clients. As I progress through my master's, I'm focusing on computational methods for electrical and computer engineering to deliver practical, research-driven engineering solutions.
