You will get a Production Python Backend with FastAPI & API Integration
Project details
You'll get the backend behind your AI product built right. FastAPI services, clean API design, a database, authentication, async handling for LLM calls, and deployment. The foundation that decides whether your product is fast and reliable or slow and fragile.
AI products live or die on their backend. LLM calls are slow and flaky, so the backend has to handle async properly, queue long-running jobs, cache aggressively, and stay responsive under load. I build for exactly that — not a generic CRUD API with an OpenAI call stapled on.
You'll receive a FastAPI backend with clean, documented endpoints, database and auth set up, async and queue handling for AI workloads, and deployment to your platform (AWS / Docker). Built to scale and easy for your team to extend.

AI Workflow Engineer – Deterministic FSM Intake System (Cost-Controlled)
Jazay was a reliable and dedicated member of our engineering team. He consistently approached tasks with a positive attitude, communicated well, and was always willing to take on new technical challenges as the project evolved.
He contributed to the development of our Resonance platform, worked collaboratively with the rest of the team, and was responsive to feedback throughout the engagement. I appreciated his professionalism, commitment, and willingness to help move the project forward.
I look forward to working with Jazay again soon and would be happy to recommend him to other clients looking for a dependable software engineer. I wish him continued success on Upwork.

Hi, I’m Jazay an AI and backend engineer with over 7 years of experience. I’ve led AI initiatives in property tech and customer service, delivering real-world systems. At TalentPop, I turned cutting-edge AI into daily-use applications.
I have built systems for large language models, retrieval-augmented generation, and full-stack Python development. Each project contributes to measurable business goals such as lower response times and reduced manual work. I ensure my AI systems are connected to outcomes before deployment.
Collaborate with me for production-ready AI solutions that streamline operations and utilize data effectively. My approach combines robust technical skills with a strong business focus, using tools such as AWS, Docker, and CI/CD for deployment.
