Work EnvironmentWeb development, API-focused projects, microservicesBroader software development, server-side logic, database management
Industry UsageTech startups, SaaS, API-driven servicesEnterprise, e-commerce, finance, various industries

Fastapi Developers specialize in building high-performance APIs using Python and Fastapi, often within microservices architectures. Backend Developers have a broader scope, working with multiple languages and technologies to develop server-side applications across various industries. While Fastapi Developers focus on API efficiency, Backend Developers handle comprehensive backend systems.

What are the key skills and qualifications needed to thrive as a FastAPI Developer, and why are they important?

To thrive as a FastAPI Developer, you need strong proficiency in Python programming, RESTful API design, and experience with FastAPI, often supported by a background in computer science or related fields. Familiarity with tools like SQL/NoSQL databases, Docker, and cloud platforms, as well as knowledge of asynchronous programming and API documentation tools like Swagger, is typically required. Excellent problem-solving skills, attention to detail, and effective communication set outstanding FastAPI developers apart. These skills are crucial for building reliable, high-performance APIs that meet modern application demands and facilitate seamless team collaboration.

What is a FastAPI Developer?

Job description

Job Title: AI ML developer

Location: Raritan, NJ

Experience: 1–5 Years

We are seeking an AI ML Developer with a strong foundation in Generative AI (GenAI) to develop and deploy AI-enabled applications and services. The role focuses on building scalable Python-based backends and integrating Large Language Models (LLMs) into real-world workflows. The ideal candidate combines strong Python development skills with hands-on experience using APIs or frameworks like OpenAI, Hugging Face, LangChain, or LlamaIndex to create intelligent and interactive applications.

 

Key Responsibilities:

  • Develop robust, modular, and testable Python applications and APIs using frameworks like FastAPI, Flask, or Django.
  • Build backend services that consume or serve LLM responses, handle session context, and manage prompt workflows.
  • Optimize performance, concurrency, and error handling for GenAI-powered applications.
  • Integrate with LLM APIs (OpenAI, Azure OpenAI, Cohere, Gemini, Claude, Hugging Face, etc.) to build intelligent assistants, summarization tools, and AI copilots.
  • Implement Retrieval-Augmented Generation (RAG) pipelines using frameworks such as LangChain, LlamaIndex, or Haystack.
  • Engineer and manage effective prompts for tasks like Q&A, semantic search, content generation, or entity extraction.
  • Work with embedding models (e.g., Sentence Transformers, OpenAI Embeddings, BERT) to convert unstructured text into vector representations.
  • Integrate and query vector databases like FAISS, Pinecone, Weaviate, or ChromaDB to power semantic search or document retrieval.
  • Package and deploy GenAI services using Docker, Kubernetes, or AWS Lambda for scalable access.
  • Collaborate with DevOps and platform teams to integrate CI/CD pipelines, logging, and monitoring.

 

Required Skills & Qualifications

  • Bachelor’s or Master’s in Computer Science, Engineering, or a related field.
  • 2–5 years of hands-on Python development experience, with emphasis on backend/API design.
  • Experience integrating GenAI or NLP models using OpenAI, Hugging Face Transformers, Cohere, etc.
  • Proficiency with RESTful APIs, JSON handling, and web-based integration patterns.
