• Working proficiency in Python – including integration, debugging and contribution to pipeline code.
• Solid grasp of API design (REST), data modeling and clean code principles.
• Comfort working with semi-structured data and transforming it into usable APIs and product features.
• Experience working in agile, distributed development teams.
