> Co-founder & Lead AI Engineer — RAG pipelines, agentic workflows, scalable LLM architectures

Abu Bakar Siddik is a Co-founder and Lead AI Engineer based in Rajshahi, Bangladesh, building agentic AI software for lawyers — and specializing in retrieval-augmented generation (RAG), agentic workflows, and scalable LLM architectures.

Previously he led the Core RAG & AI Team at AskTuring.ai, building a production RAG platform without vendor lock-in that scaled from 100 to 10,000+ concurrent users with ChatGPT-level latency. He cut hallucinations by 98% with hybrid search, reranking, and strict source-grounding; designed multi-agent workflows with explicit state management; and built a time-aware RAG system with short-term, long-term, and semantic memory layers.

Before AskTuring he shipped private on-premise air-gapped AI for enterprise clients at Sazim Tech, designed hexagonal multi-provider LLM architectures, and built a 3M+ sample RAG application end-to-end. Earlier work included Bengali ASR research, Rasa-based conversational AI, and Bengali NLP datasets at Intelsense AI.

He won the Google Nano Banana Hackathon 2025 with MagicSpin 360° (single-image-to-3D rotation pipeline using Gemini Pro Vision + Stability AI + Segment Anything).
