HAILHuman In the AI LoopAI Assisted, Human Led.
I'm Sudheerkumar Gujjeli — an AI Engineer at GSK through Cognizant and Founder of HAIL — Human In the AI Loop with 14+ years of enterprise delivery. I build production RAG, agentic and cloud-native systems where quality is measurable, decisions are auditable and humans remain in control.
Empowering UK Domains to Embrace AI
What I'm building toward
The interesting problems live where models meet messy enterprise reality. I build the seams.
Applied AI engineering
Production RAG pipelines, LLM orchestration, agentic workflows and responsible AI evaluation with Python, FastAPI and Azure OpenAI.
Human-led AI systems
HITL audit architectures, RAGAS quality governance and Voice AI that keep consequential decisions reviewable, measurable and accountable.
Enterprise architecture
Cloud-native .NET and Angular platforms, Azure AKS, Kafka event streaming and Camunda workflows delivered across complex organisations.
From enterprise platforms to production AI.
