• 🛠️ Providing AI automation services (WhatsApp bots, chatbots, integrations) for small and medium businesses
• ☁️ Running my own infrastructure: an always-on Ubuntu server and a local GPU (RTX 3060) for inference and fine-tuning
• 📚 Continuously studying LLM techniques: fine-tuning, QLoRA, RAG, quantization, and model merging
