Hi, I'm Faizal Mangiwa👋

AI Engineer | LLM Applications | RAG | AI Agents | Fine-Tuning

I build practical AI systems that combine LLMs, retrieval, agents, model orchestration, fine-tuning, and production-oriented application architecture.

My focus is turning AI capabilities into working software — not just prototypes.

🚀 What I Build

  • LLM Applications — OpenAI, Gemini, Groq, OpenRouter, Ollama
  • RAG Systems — hybrid retrieval, reranking, evaluation, multi-tenancy
  • AI Agents — orchestration, tool calling, self-healing workflows
  • Fine-Tuning — LoRA, QLoRA, quantization, model evaluation
  • AI Automation — web scraping, structured extraction, intelligent workflows
  • AI Developer Tools — code generation, optimization, benchmarking
  • Model Deployment — Modal and cloud-based inference
  • Interactive AI Applications — Gradio and Streamlit
