Nikolaos Chatzinikolaou

I'm a full-stack developer and certified Scrum Master with hands-on experience building scalable web applications and leading agile teams from sprint planning through delivery. My technical stack spans the modern web ecosystem: on the frontend, I work primarily with Next.js, React, and TypeScript, crafting responsive interfaces with Tailwind CSS and component libraries like shadcn/ui. On the backend, I build robust APIs using Python (FastAPI, Django, Flask) and Node.js, with PostgreSQL, MongoDB, and Redis powering the data layer.

DevOps is a core part of how I ship. I'm comfortable with Docker, Kubernetes, and CI/CD pipelines using GitHub Actions, GitLab CI, and Jenkins, and I deploy across AWS, Vercel, and GCP with infrastructure-as-code tools like Terraform. I monitor production with Grafana, Prometheus, and Sentry to keep systems reliable.

As a Scrum Master, I run ceremonies, manage backlogs in Jira, and remove blockers so engineers can focus on building. I'm fluent in agile estimation, sprint retrospectives, and cross-functional collaboration with product, design, and QA. My strength is bridging technical execution and team process — writing production code one moment and unblocking a sprint the next, always with a focus on delivering measurable business value.
