Fine-tune GPT-4o Mini and GPT-3.5 Turbo through OpenAI's API with systematic hyperparameter optimization, validation splits, and automated evaluation.
Fine-tune Llama 3, Mistral, Phi, and other open-source models using LoRA, QLoRA, and full fine-tuning on cloud GPUs or your own infrastructure.
Rigorous evaluation against your specific tasks with automated benchmarks, human evaluation, and A/B testing against base models to quantify improvement.
Align model outputs with human preferences using DPO (Direct Preference Optimization) and RLHF techniques for better quality and safety.
Deploy fine-tuned models via OpenAI, vLLM, TGI, or Ollama with optimized inference, batching, and auto-scaling for production workloads.

We implement row-level security, encryption at rest and in transit, and role-based access controls for marketing agencies data. Audit trails log every access and modification for regulatory review.
marketing agencies systems we build use VPC isolation, encrypted secrets management, and automated vulnerability scanning. For AI features, we add PII redaction in prompts and on-premise model hosting when required.
Compliance is tested, not assumed. We run automated checks for marketing agencies regulatory requirements at every CI/CD stage — so compliance issues are caught before code reaches production.
Post-launch, we monitor for compliance drift with automated alerts on access patterns, data flows, and configuration changes. Quarterly compliance reviews are included in our maintenance agreements.
