About

I am a Senior Software Engineer with 20 years of full-stack development experience spanning desktop, web, and mobile platforms. Over my career, I’ve co-founded startups and specialized in automation, CI/CD, and scalable cloud solutions utilizing AWS, Azure, and GCP. My skill set includes proficiency in Java, C#, JavaScript frameworks, and both SQL and NoSQL databases.

My experience ranges from leading complex projects involving architecture and delivery to modernizing legacy systems and implementing microservices. I enjoy working in high-performance environments, managing CI/CD pipelines, and developing scalable SaaS, PaaS, and serverless solutions across multiple cloud providers.
