About

Hi, I’m Nikola Bucić, a Senior Full-Stack Developer with over 15 years of experience building scalable web platforms, APIs, and SaaS products. I’ve led DevOps initiatives in AWS, architected high-traffic solutions, and guided teams through complex architectural migrations. I was an early adopter of AI-assisted development workflows with proven delivery impact.

I specialize in API-first design, modern frontend-backend stacks, and data-driven optimization. My strengths include building end-to-end systems, reducing delivery times, and improving operational efficiency through automation and intelligent tooling. I enjoy mentoring teams and delivering reliable software in fast-paced environments.
