Hello, I build production grade AI, backend, blockchain, Trading, and full stack systems for startups and engineering teams that need clean execution, not just prototypes. My core work includes LLM-powered apps, RAG pipelines, AI agents, automation workflows, trading platforms, algorithmic trading systems, scalable APIs, gRPC microservices, distributed backends, and cloud-native platforms. I work with Python, Go, Node.js, TypeScript, React, Next.js, PostgreSQL, MongoDB, Kafka, Supabase, AWS, GCP, and Azure. On the AI side, I build with OpenAI, LangChain, LangGraph, Hugging Face, vector databases, embeddings, and multi-agent workflows. I focus on clean architecture, reliable data flow, strong evaluation, and systems that can run in production. I also work with fintech, trading, and blockchain systems, including trading bots, market data pipelines, exchange integrations, order execution logic, risk controls, smart contracts, applied cryptography, DAML/Canton Network, Solidity, distributed ledgers, wallets, and Web3 backend infrastructure. - AI Saas products and LLM powered workflows. - Trading platforms, trading bots, and algorithmic strategies. - Backend APIs, microservices, and distributed systems. - RAG, vector search, and automation pipelines. - Blockchian, smart contract, and DAML/Canton solutions - Full stack products with React, Next.js, Node.js, Python, and Go, etc. I am practical, fast, and architecture minded. I care about building systems that are secure, scalable, maintainable, and ready for real users.
