Professional Experience

Senior AI Engineer

2022 - Present

NeuralBridge

  • Built an end-to-end AI Expert Matching platform, designing a LangChain-orchestrated multi-model evaluation system (leveraging LLaMA, Mistral, GPT, and Gemini) to assess expert quality, alongside a hybrid LLM + anomaly detection pipeline for fraud prevention and identity verification. Replaced keyword search with a RAG-based semantic matching engine using vector databases like Pinecone and Weaviate, and independently owned the full stack from system architecture and AI pipelines to frontend development and AWS deployment.
  • Developed an AI Book Writing Assistant using multi-stage prompt pipelines (outline generation → structured drafting → revision loops) powered by GPT and Gemini to automate long-form content creation while preserving narrative consistency through stateful prompt chaining and context management. Delivered as a full-stack product with seamless integration into React and WordPress.
  • Built a Real-time crypto analytics platform (BubbleMap-style) with sub-second latency, streaming on-chain data via Node.js and WebSocket, and visualizing dynamic network activity using React and D3.js. Implemented unsupervised anomaly detection to identify suspicious wallet clustering and transaction velocity patterns, uncovering signals not visible in traditional charting tools.
  • Built MindAI SwapBot, an AI-powered Telegram bot using Telegram and LLMs to interpret natural language swap requests and safely execute on-chain transactions through robust intent-parsing pipelines that handle ambiguity in high-stakes financial contexts.
  • Built a Digital asset access control system with ML-based behavioral anomaly detection — flags access pattern deviations before they escalate to breaches.
