# Tivadar Papai

**Headline:** Professional profile
**Location:** &lt;UNKNOWN&gt;, &lt;UNKNOWN&gt;, &lt;UNKNOWN&gt;

## About

Tivadar Papai is a backend and AI engineer who primarily works with the Python ecosystem\. He builds production AI and ML systems, APIs, microservices, AI services, and data pipelines, with experience across FastAPI, Flask, Django, Spark, and Airflow\. Tivadar combines machine learning work with distributed\-systems and cloud\-infrastructure expertise, taking a holistic approach that optimizes complete systems rather than model accuracy in isolation\. Tivadar is strongest at balancing model quality with production requirements, including latency, cost, reliability, and operational constraints\. At Waymo, he worked on a real\-time trajectory\-ranking system for autonomous driving, where safety, cost, and latency had to be considered together\. His AI and ML experience includes PyTorch, TensorFlow, LangChain, and Llama Index\. Tivadar focuses on applying AI to real business problems and designing architectures that account for operational constraints from the outset\.
