hi i'm rishabh.
i'm a cs student at penn state who builds useful AI tools, research demos, and internet products.
lately i've been working on LLM caching, an OCT scan LLM model, and tiny tools that should feel obvious once they exist.
want to talk? email rishabhsaiv@gmail.com. you can also find me on github, hugging face, linkedin, and twitter.
work.
i try to keep the work visible. there are 25 public builds on the projects page: research labs, student utilities, developer tools, hackathon hardware, data APIs, and older experiments that still show the path.
Cache Atlas - a public Hugging Face space for exploring KV-cache memory, notes, and LLM caching research.
OCT Copilot Lab - an OCT scan LLM model lab for classification, Grad-CAM style highlights, and report experiments.
PDFSpacer - a no-login PDF editor that adds blank space into worksheets, diagrams, and forms.
1000dates - a waitlist experiment around simulated dating paths and better matching.

current thread.
2023 - started shipping AI projects for students, mental-health support, and school workflows.
2024 - built local LLM tools, developer utilities, hackathon judges, and product experiments while starting CS at Penn State.
2025 - worked across Perplexity, Mashreq, TrendFlip, Nas, and public Hugging Face research demos.
now - focused on useful AI systems: LLM caching, medical imaging workflows, and small products that people can actually open.
places i worked.
the short version. the full version is on the experience page.
Mashreq Bank - ai/llm intern | Jun 2025 - Aug 2025. built internal AI tools, a unified MCP server, and an intern portal across React, FastAPI, and PostgreSQL.
Nas Company - ai summer resident | Jul 2025 - Aug 2025. selected as 1 of 11 from 18,000+ applicants and built Briefly inside the Dubai AI startup residency.
TrendFlip - founder | Jan 2025 - now. uses AI-assisted sourcing and pricing workflows for collectible resale, scaled to about $30K annual revenue.
Perplexity - campus partner | Jan 2025 - Dec 2025. built a campus UGC network, ran demos and outreach, and drove 250+ Comet browser downloads.
selected builds.
the homepage keeps only the strongest few. the rest live on the projects page.

Building developer tools for Cursor
How two small extensions clarified what developers actually want from prompt automation.
currently building more AI research demos, keeping old projects accessible, and trying to make the useful things easier to find.
