About

I am a technology enthusiast with over 14 years of experience building and maintaining scalable software systems. I enjoy learning new tools, breaking down complex problems, and sharing what I’ve learned with others. My work spans full-stack development, system migrations, cloud-native architecture, and API integrations across industries such as e-commerce, real estate, and banking.
I’m comfortable defining requirements, guiding teams, and translating client needs into maintainable solutions. I’ve led the development of internal tools, worked on high-volume data pipelines, and implemented CI/CD practices across multiple environments. I write code in C#, TypeScript, and Python, and regularly work with Azure, GCP, and AWS using tools like Kubernetes. I value clean design, thoughtful problem-solving, and a practical approach to delivering maintainable software.
