What LLM developers you hire work on

Retrieval-augmented generation

Ingestion, embeddings, hybrid retrieval, re-ranking and grounded, cited answers.

Fine-tuning & adapters

When style, format, latency or accuracy justifies it — benchmarked against RAG-only baselines.

LLM application development

Assistants, copilots, search and workflows, kept provider-portable.

Evaluation & LLMOps

Versioned test sets, automatic and human scoring, monitoring of quality, latency and cost.
