Hi, I'm Alex Rendler
Full-stack developer crafting elegant solutions to complex problems
AI Engineering Expertise
Production-Ready AI Infrastructure
I architect and implement advanced AI systems with deep expertise in RAG (Retrieval-Augmented Generation), vector embeddings, and semantic search. My work spans from designing chunking strategies for optimal context retrieval to building scalable AI pipelines that integrate local LLMs, prompt engineering, and real-time data processing.

Designing Artificial Intelligence That Builds Intelligence
At AIcademy, I engineered an AI tutor system that fundamentally reimagines how students interact with educational content. Instead of providing direct answers, the AI acts as a learning coach,dynamically injecting real-time lesson content, student progress data, and quiz scores into its context to deliver personalized, Socratic-method guidance.
The technical innovation lies in the prompt engineering and response architecture: every AI interaction references specific curriculum material, asks three guiding questions, and enforces a consistent pedagogical structure through post-processing. This prevents passive learning while teaching students to leverage AI as a thinking partner rather than an answer machine—critical skills for the AI-driven workplace.
