About Me
A resourceful and results-driven software developer with a strong foundation in algorithms, full-stack development, applied AI and LLMs. From leading multiple academic projects to building end-to-end products, I’ve consistently turned ideas into solutions serving the real world. I’ve built fast, scalable apps with real-time performance using React, React Native, Next.js, Django, Flask, FastAPI, Node, Firebase, SQL, and NoSQL — across both web and mobile (cross-native). On the AI side, I’ve worked primarily on Generative AI side (LLMs, LangChain, advanced RAG pipelines & NLP) and a little of CV to build smart, efficient applications. Across 4+ industry projects, I’ve contributed to products under deadlines and evolving requirements consistently. Hackathons have further sharpened my ability to solve problems fast and work in teams collaboratively. I’ve been an active problem solver on LC (LeetCode) and with a rating of 1750+, placing me in the top 10% globally, with multiple top AIRs in Weekly and Biweekly contests, reflecting my strong grasp of data structures and algorithms. Always up for solving meaningful problems with tech. You can reach me at piyanshugehani@gmail.com.
