## About

Software Engineer with hands\-on experience building production\-grade AI systems and full\-stack applications across the IT industry\. At Sopra Steria, I design and ship agentic AI systems — LLM\-powered agents that call external tools, retrieve context through RAG pipelines, and execute multi\-step workflows autonomously\. I work across the full backend stack: FastAPI services, RESTful microservices, vector database integrations, and Selenium\-based automation frameworks that cut manual QA effort significantly\. Before that, at 75way Technologies, I built and deployed full\-stack products using React, Next\.js, Node\.js, and React Native — shipping features across web and mobile for real users, with REST APIs and MongoDB/PostgreSQL as the data layer\. My stack: Python · LangChain · LangGraph · OpenAI/Claude APIs · FastAPI · Node\.js · React · React Native · MongoDB · PostgreSQL · AWS · Docker · Selenium I write clean, testable code\. I care about system design, not just syntax\. Open to Software Engineer roles where strong engineering and applied AI intersect\.
