I’m Mark Rutiaga, a senior full-stack engineer with 10+ years of experience building scalable, cloud-native enterprise applications. I focus on designing and delivering secure backend services with Python (Django/Flask/FastAPI) and modern frontend experiences with React and TypeScript, often turning complex workflows into clean, reusable components and APIs. I’ve worked across AWS, Azure, and GCP, containerized systems with Docker, and supported reliable CI/CD pipelines using tools like GitHub Actions and Jenkins. I also enjoy architecture and distributed systems work—building event-driven services with RabbitMQ/AWS SQS/Celery, optimizing databases (PostgreSQL/MongoDB), and improving observability with monitoring stacks like Grafana, Prometheus, Datadog, and Sentry.…I’m Mark Rutiaga, a senior full-stack engineer with 10+ years of experience building scalable, cloud-native enterprise applications.
