🔹 Founding CTO | AI Engineer | 7 Years Building Production ML Systems I'm Abhijoy — currently Founding CTO at PromptGuard, where I lead engineering for an AI agent safety platform (10,000+ users across SDK, MCP server, and framework integrations), and an AI Consultant at PwC. Before that, I built a 30B-parameter enterprise LLM from scratch at Multiverse Computing and shipped the voice search system serving 200M+ daily users at Flipkar. 📈 What I bring: Distributed training (PyTorch FSDP, DeepSpeed, Megatron-LM), inference optimization (vLLM, TensorRT, quantization), and model compression. Co-author of CompactifAI (ESANN 2025) — cut LLM parameter count 70% and memory footprint 93% at a 2-3% accuracy cost. Led engineering teams of 10+ across research and production delivery. Shipped systems from 0 to 200M+ daily users. 🎯 How I can help: 1:1 consultations for engineers and founders on LLM training, inference optimization, model compression, and agentic systems. Technical advisory for early-stage AI startups — architecture, hiring, and delivery strategy. Priority DM for quick technical questions. Based in Bengaluru, open to remote work worldwide.
