Almost 3 years building backend systems and automation tools, including an internal AI agent that handles support tickets on its own, plus full-stack apps I design and ship end to end.
About
I spent the last three years as a Software Administrator (functionally a software engineer) at Friedman Vartolo LLP, a law firm, building backend systems and automating manual workflows. The project I'm proudest of is an internal AI agent I helped build on Claude. It researches support tickets, queries databases, and carries out tasks through Playwright and API calls, and now reliably handles more than half of the team's routine tickets on its own. I also built a monitoring framework that's saved the firm 479+ hours of manual work to date, plus full-stack internal tools with Streamlit and FastAPI, deployed on Azure. I also build things on my own time, like Riffstub, a concert tracking app I designed and shipped solo.
I graduated from SUNY Old Westbury with a B.S. in Computer and Information Science in 2022.
Projects
Next.js · TypeScript · React · PostgreSQL · Supabase · Vercel
A full-stack concert tracking app, designed, built, and deployed solo, from database schema through production hosting on a custom domain.
- –Email/password auth with optional TOTP two-factor, and PostgreSQL row-level security to lock down each user's data
- –Integrated Ticketmaster, SeatGeek, and Spotify with custom rate limiting and attribution
- –Built a custom content moderation system with automated filtering and an admin review queue
Set → Playlist
Python · Spotify API · YouTube Data API
A fun side project: paste a YouTube DJ set and get a Spotify playlist of every track in it, with fuzzy matching to find the right version of each song.
- –Parses tracklists from video descriptions, chapters, or comments, cleaning up timestamps, tags, and promo text
- –Scores each Spotify match on title and artist similarity, flagging uncertain ones for manual review
- –Runs as either a CLI or a browser UI, with tests backing the matching logic
