Backend + AI Systems
Hey, I'm Cristyan Sepulveda. Software Engineer.
I currently work at Apple, building LLM-powered systems with solid guardrails, practical evaluations, and careful rollouts.
About
Based in Amsterdam, originally from Colombia.
I build systems around LLMs: metadata ingest for better context, evaluation pipelines, and stronger pre-filtering before generation.
Current Focus
- LLM Integration Systems
- Context & Prompt Orchestration
- Metadata Pipelines
- Pre-filtering & Guardrails
- Evaluation Workflows
- Monitoring & Alerts
- Latency & Cost Tuning
Let's Connect
Happy to connect about LLM product systems, evaluation pipelines, and reliable backend architecture.
