• Review code and provide technical guidance to engineering teams to maintain high-quality standards.
• Partner with product and engineering leaders to evaluate trade-offs related to scalability, security, cost, and speed.
• Design APIs, database schemas, caching strategies, and distributed systems to support platform requirements.
• Guide teams in handling edge cases, failure scenarios, and observability to ensure system robustness.
• Identify architectural bottlenecks and propose scalable improvements to enhance platform performance.
• Evaluate new technologies and frameworks to keep the platform innovative and competitive.
• Improve system monitoring, instrumentation, and reliability practices to ensure high availability and resilience.
