• Solid understanding of relational databases and data modeling (PostgreSQL, MySQL, etc.)
• Experience designing APIs and application architectures

• Experience working on B2B or operational software
• Experience with cloud infrastructure (AWS, GCP, etc.)
• Experience taking products from MVP to production
