- Build secure RESTful APIs, GraphQL APIs, and microservices.
- Develop cloud-native backend platforms.
- Design scalable databases and caching strategies.
- Integrate multiple AI providers and LLM APIs.
- Build Retrieval-Augmented Generation (RAG) systems.
- Develop AI agents capable of reasoning, orchestration, and workflow automation.
- Design prompt engineering frameworks and AI pipelines.
- Implement vector databases and semantic search.
- Develop event-driven architectures and asynchronous processing.
* Build automated testing frameworks.
* Implement CI/CD pipelines.
- Monitor, optimize, and secure production environments.
- Evaluate emerging technologies and recommend improvements.
- Mentor junior developers and contribute to engineering best practices.
Required Qualifications
- Bachelor's degree in Computer Science or equivalent experience.
- 5+ years of backend software development.
- Strong proficiency in Python, Node.js, Java, or Go.
- Experience with FastAPI, Express.js, Spring Boot, or similar frameworks.
