About the role

  • Developing and implementing scalable backend systems, APIs, and microservices using FastAPI
  • Install best practices for software development, ensure designs meet requirements, and deliver high-quality work on schedule
  • Writing application backend codes using Python, SQL, async/await patterns, using strong object-oriented principles, asynchronous programming
  • Implementing dependency injection patterns using dependency injector library
  • Integrating Azure OpenAI (GPT-4, GPT-4 Vision) with proper retry logic and error handling
  • Building LLM observability using Langfuse for tracking prompts, tokens, costs, and latency
  • Developing prompt management systems with versioning and fallback mechanisms
  • Implementing Celery workflows for async task processing and complex pipelines
  • Building multi-tenant architectures with client data isolation
  • Developing layered architecture (Service, Foundation, Orchestration, DAL patterns)
  • Implementing cost optimization for LLM usage (prompt caching, batch processing, token optimization)
  • Troubleshooting backend application codes with structured logging and distributed tracing
  • Developing and implementing back-end architecture following SOLID principles and design patterns
  • Integrating third-party APIs (Veeva Vault, Adobe PDF Services, OCR services)
  • Documenting application changes and developing updates using OpenAPI/Swagger
