Syed Saad Hasan E.

AWS Machine Learning Specialty certified engineer with published ML research (MediaEval 2026, 1st place). I build AI/LLM applications and the cloud backends that run them — from RAG systems and AI agents to computer-vision pipelines and FastAPI services on AWS. What I deliver: • LLMs & AI Agents — RAG over your data, chatbots, tool-calling agents and agentic workflows (OpenAI, LangChain), with tracing and evaluation (Langfuse) • Computer Vision & ML — real-time detection & tracking (YOLO, ONNX/TensorRT), pose/movement analysis, model fine-tuning • Automation — web scraping (Scrapy/Playwright), data pipelines & ETL (Airflow), API integration and scheduled jobs • Backend & Cloud — FastAPI microservices & REST APIs, AWS (ECS/Fargate, Lambda, SageMaker), Terraform IaC, Docker, CI/CD, blue-green deploys Tell me what you're building, and I'll give you the honest tradeoffs before we start.
