👋 I'm Guna — building real AI systems and documenting the process.
Not wrappers. The actual engineering behind systems that ship in production - LLMs, RAG pipelines, agentic architectures, transformer internals, and the infrastructure underneath.
@ Pfizer — Generative and Agentic AI Engineer (PSSM). Building AI-driven solutions across pharmaceutical workflows, clinical data pipelines, and regulatory intelligence using LLMs, RAG, and multimodal systems.
Outside work — research and build across:
- 🧠 LLM Engineering — LoRA/QLoRA fine-tuning, activation tracing, mechanistic interpretability, PLE architectures on Gemma 4 E4B
- 🔍 RAG Systems — Production-grade retrieval pipelines, hybrid search, agentic retrieval operating systems
- 🤖 AI Agents — Multi-agent orchestration, deterministic execution replay, causal audit trails for agent behaviour
- 🏥 Healthcare AI — Clinical NLP, medical imaging, drug entity extraction, pharma regulatory intelligence
- 🗺️ Codebase Intelligence — Researching the hidden cost of AI-generated code in engineering teams
