GenAI Engineer \| Backend Engineer — LLM Agents, RAG, LangChain/LangGraph, AWS Bedrock \| Blockchain & DeFi Backend Systems

## About

I'm a Software/GenAI Engineer with 9\+ years of experience, including hands\-on work building and deploying generative AI systems — LLM\-powered agents, prompt engineering pipelines, and agentic workflows using LangChain, LangGraph, and AWS Bedrock — alongside 6\+ years designing secure, scalable backend systems for global financial and enterprise clients\. At Protokol BV, I build AI\-powered chat modules using AWS Bedrock, LangChain, and LangGraph, and integrate Retrieval\-Augmented Generation \(RAG\) pipelines to ground agent responses in real\-time on\-chain and platform data\. I deploy and monitor these services on AWS ECS with AWS CloudWatch, using AWS S3 and AWS Lambda for storage and event\-driven processing\. I've also designed a self\-repaying loan protocol \(Taurus Loans\) and a decentralized governance and security framework for DeFi ecosystems \(Vedyx Network\), applying specification\-driven and test\-driven development practices to keep production systems reliable\. I've managed production systems with real financial stakes — growing a platform's active value from $0 to $100K within its first month at Bhavish Finance, and maintaining $1M in actively managed value at Oddz Finance\. Beyond backend and AI work, I enjoy building full\-stack, end\-to\-end products\. I recently built Aurora, an offline, privacy\-first AI Android app combining a Flutter interface with a Rust core for on\-device inference, and Aignt\.fun, a conversational DeFi strategy agent\. I write technical tutorials on LangChain and LangGraph on my website, and I enjoy mentoring engineers — having trained and onboarded over 20 team members across my career\. I've collaborated closely with distributed, multidisciplinary teams across Europe and globally, and I'm always happy to connect with fellow engineers working on applied AI or backend systems\. 🔗 harishkumargunjalli\.in
