Samet Soysal - AI/ML Engineer

Typing animation: production AI systems, RAG pipelines, multi-LLM orchestration, MCP-driven agents

Portfolio GitHub projects LinkedIn Email


About

I am a Computer Engineering graduate building production AI systems where models meet real data engineering: retrieval pipelines, OCR-heavy document workflows, multi-model routing, and agentic products that need to be fast, observable, and usable.

AI systems
RAG, vector search, OCR, local/cloud LLM routing, cited answers, and evaluation loops.
Product engineering
FastAPI, React/Next.js, TypeScript, Docker, PostgreSQL, MongoDB, Firebase, and CI.
Automation
LangGraph agents, Playwright/RPA, n8n workflows, market-data pipelines, and analytics.
