• Team Technical Leadership: Provide direct mentorship, technical direction, and code/design review guardrails for a team of 5 backend engineers.
• Design & Best Practices: Define microservices patterns, database communication strategies, data validation frameworks, and performance-tuning guidelines for the new ecosystem.
