About Ratul Roy

Backend Engineer | Data Pipeline Architect | Python Advocate I build backend systems that turn data into actionable insights. With 4+ years of experience in maintaining backend for ETL workflows and optimizing data pipelines. My detail oriented work has boosted pipeline efficiency in Volue by 60% and ensured uninterrupted data flow for stakeholders, letting innovation thrive. Technical Expertise Languages: Python, JavaScript, Rust Backend: Airflow, Django, Django REST Framework, FastAPI DevOps: GitHub Actions, CI/CD, Docker, Kubernetes, Kafka, Linux Cloud: GCP, Terraform, Azure, AWS Databases: PostgreSQL, YAML-based configuration engines Practices: Distributed systems, pipeline optimization, collaboration Agile: Kanban, Scrum What Drives Me I’m passionate about solving complex backend challenges—like containerizing legacy systems or scaling data ingestion for large user bases. At Cefalo, I architected a YAML-driven data retrieval engine that slashed adaptive maintenance efforts by 60%, while collaborating with data scientists and engineers to bridge gaps between ML models and infrastructure. My experience spans data pipelines (e.g, Japan’s deregulated energy markets) and tools that help to interact with the system (iCurve). I’m eager to contribute to platforms that redefine how people experience the world. My strengths in scalable backend services, container orchestration, and data-driven problem-solving align with teams building seamless, personalized global experiences.
