About Me

I'm a Full Stack & DevOps Engineer with hands-on experience in building, deploying, and operating modern cloud-native applications. I specialize in developing scalable web applications and designing robust backend systems, while also managing the infrastructure and delivery pipelines that support them.

My work spans the full software lifecycle — from feature development and system modernization to performance optimization, cost reduction, and production reliability. I enjoy solving complex technical challenges, improving system reliability, and building solutions that scale in real-world environments.

I'm available for freelance projects where I can bring value through end-to-end development, DevOps transformation, or cloud infrastructure optimization.
