I am a backend-focused software developer with industry experience at PAR Technology (NYSE: PAR).
My background combines software engineering, machine learning systems, cloud infrastructure, and financial data analytics. Before transitioning into software engineering, I worked for many years in corporate banking as a Project Manager and Data Analyst, where I led large-scale lending platforms and enterprise analytics systems.
I specialize in building scalable backend services, RESTful APIs, ML pipelines, and production-grade cloud deployments.
