  • Implement secure handling of credentials and sensitive data, particularly with third-party services.
  • Develop automation capabilities to run tasks and checks at specified intervals.
• OpenAI API Integration
  • Connect with the OpenAI API (or similar AI services) to manage language model interactions.
  • Construct, send, and parse responses from AI prompts, ensuring correct context usage.
  • Implement fail-safes and logging to handle errors or performance issues related to AI calls.
• Database & External Integrations
  • Design and optimize queries for SQL or NoSQL databases.

• Collaboration & Communication
  • Work remotely with a cross-functional team (PMs, designers, QA) to define and deliver features.
  • Participate in code reviews, sprint meetings, and planning sessions.
  • Document system architecture, endpoints, and operational procedures.
• Security & Performance
  • Enforce role-based access control to differentiate user privileges.
  • Optimize front-end and back-end performance to handle large data sets and high concurrency.
  • Monitor application logs and metrics, troubleshooting errors or bottlenecks.
