Data / Human Feedback Support
Real-time help building training data — human feedback and annotation with Argilla, and synthetic and preference dataset generation with Distilabel — the data that makes SFT, DPO, and RLHF work.
Fine-tuning underperforming because the data is thin, noisy, or missing preference pairs? Model quality is capped by data quality, and building good SFT/DPO datasets is its own discipline. We help you create and curate the data that actually moves the needle.
Data quality, not algorithm choice, usually decides fine-tuning outcomes. We help you build it with the Hugging Face data tooling: Argilla for human annotation and feedback — setting up datasets, guidelines, and review workflows so humans label, rate, and correct model outputs efficiently — and Distilabel for programmatic synthetic-data and preference-dataset generation, using LLMs to produce and score examples at scale (for SFT instruction data and DPO/preference pairs). We cover pipeline design, quality control and filtering, deduplication, mixing human and synthetic data, and shaping the result into the exact format TRL trainers expect. This is the upstream work that makes SFT, DPO, GRPO, and reward modelling succeed.
What We Offer
From daily job support to emergency production fixes, proxy interview guidance, and interview coaching — we have the expert for your specific need.
Hands-on help on real tickets — architecture, implementation, debugging, and code review on your actual Hugging Face stack (Transformers, PEFT, TRL, Diffusers, Sentence Transformers, huggingface_hub) during your working hours, not generic tutorials.
Firefighting for live incidents — GPU memory, latency, throughput, quantization, adapter loading, endpoint reliability, retrieval quality, and cost problems resolved with an LLM engineer on the call.
Hugging Face, LLM, and GenAI interview questions covered end-to-end plus profile positioning so you can both keep your job and land the next one.
