Backend Developer → MLOps Engineer

Backend Developer to MLOps Engineer: APIs to ML Pipelines

A comprehensive roadmap for backend developers transitioning to MLOps engineering. Your existing expertise in building robust APIs, managing databases, orchestrating deployments, and implementing CI/CD pipelines translates remarkably well to ML infrastructure. Backend developers already understand the fundamentals of production systems: reliability, scalability, monitoring, and automation. MLOps extends these concepts to machine learning workflows, where you'll apply your skills to model serving, experiment tracking, feature stores, and ML pipeline orchestration. This path focuses on bridging your backend knowledge with ML-specific requirements. You'll learn how model artifacts differ from traditional code deployments, why data versioning matters as much as code versioning, and how to build infrastructure that supports the iterative nature of ML development. Your experience with Docker, Kubernetes, and cloud services provides a strong foundation for containerizing models and deploying inference endpoints. By the end of this path, you'll be able to design and implement end-to-end ML pipelines, deploy models to production, monitor model performance and data drift, and build the infrastructure that enables data scientists to iterate quickly. The transition leverages what you already know while filling in the ML-specific gaps.
