Shivam Pandey — Software Developer
Available for Work

Software Developer @ TechOTD Solutions

I'm a results-driven software developer with hands-on experience shipping three production AI products from concept to deployment. I specialize in hybrid RAG retrieval, multi-agent orchestration, and cloud-native architectures across Next.js, FastAPI, LangGraph, and native Android stacks.

My work spans Indian and Taiwan legal AI platforms to Android transcription apps — all built on real infrastructure, serving real users. I care deeply about system design and writing clean, maintainable code.
