About Me Projects

My Expertise

I'm passionate about backend development, distributed systems, and building scalable, intelligent software.

With experience across companies like IBM, Cisco, and Porsche Engineering, I've worked on a variety of software challenges - from backend development and workflow automation to real-time data processing and AI-driven applications. My technical background includes designing high-performance backend systems, optimizing large-scale data workflows, and integrating machine learning models for intelligent automation.

I'm particularly interested in the intersection of software engineering and AI, exploring how automation, distributed systems, and scalable architectures can enhance performance and efficiency. Whether working on backend services, cloud-native solutions, or data-driven applications, I enjoy solving complex problems and building software that scales.
