About Me

I'm Achyut Katiyar, a software engineer pursuing a Master's in Computer Science at Northeastern University. Most of what I build now runs on top of language models. PayPhone is an agent that takes one spending authorization and settles $0.01 per active second of a video call on Base. PayGuard AI puts GPT-4 function calling behind a spend limit, and SkillBridge AI pairs GPT-4 with ElevenLabs voice across 70+ components and 14 API endpoints.

I'm currently Co-Chair of Hackathon and Marketing for the MIT Bitcoin Expo, where I built the official event website and coordinate the 36-hour hackathon. I also serve as a Teaching Assistant for CS2000 at Northeastern.

At Maven Realty I work full stack across three codebases: the Aptava agent platform in Angular, its Express API, and the public rentals site in Vue 3. That is where the production engineering lives, from an 18-document DocuSign lease pipeline to a socket leak that was killing lease drafts in production. The range runs wider than that. Solidity and Move smart contracts, a C++ Kanban board with primary-backup replication and vector clocks, and two undergrad ML research projects at 82% and 78% accuracy. I've won over $3,000 in hackathon prizes.
