Rijo Reji

Software Engineer, AI Agent Builder, Full-Stack .NET Developer, Cloud & Data Engineer

I craft scalable full-stack applications with ASP.NET Core & React, and build multi-agent AI systems that turn complex workflows into effortless experiences.

Engineer by craft, builder by heart.

I'm a Software Engineer at UST in Trivandrum, Kerala, where I design and build robust web applications with ASP.NET Core, C# and SQL Server, and increasingly, AI-powered solutions that automate real-world workflows.

My sweet spot is where solid backend engineering meets agentic AI: orchestrating multi-agent pipelines with LangGraph, integrating LLMs into products, and moving data reliably across Microsoft Azure with Azure Data Factory.

I hold a B.Tech in Computer Science & Engineering and four Anthropic Claude certifications, including Claude Certified Architect – Professional, and I was honoured with UST's 2026 D3 Award. I keep my problem-solving sharp on LeetCode, and I love learning fast, writing clean code, and shipping things people genuinely enjoy using.
