Hi, I am

Ali Gülüstan

AI Engineer / AI Context Manager

I build LLM-powered products, RAG systems and autonomous AI agents. My job is to make models do the right thing with the right context.

About

As an AI Engineer and AI Context Manager, I work on systems that turn large language models into real products. My focus is making LLMs produce reliable, measurable and sustainable output — not just impressive demos. What started with prompt engineering today covers context engineering, retrieval architectures and multi-step agent systems.

RAG pipelines, vector-based information retrieval and tool-using autonomous agents are at the core of my daily work. I believe the outcome is shaped not only by what a model says, but by which context it is given, in which order and within which budget — which is why I treat context design as its own engineering discipline.

I have built production integrations with the OpenAI and Anthropic ecosystems; evaluation (eval) processes, cost optimization and guardrail design are a natural part of my projects. The goal is simple: turn AI from a marketing line into the hardest-working member of the team.

How I work

  • Discovery

    Use case, data sources and success criteria are made explicit.

  • Measurement

    An eval set and baseline metrics are defined so improvement becomes measurable.

  • Development

    Retrieval, prompting and agent flows are built in small steps.

  • Monitoring

    Cost, latency and quality are tracked in production.
