Alexander Szeremeta

BSBA, Management Information Systems Class of 2030

I study business at Northeastern and ship software between classes: a Mac music player, two iPhone apps, and the plumbing that gets 1990s modems online over internet phone lines.

I build for audiophiles, Huskies fans, Ukrainians abroad and 1990s modems.

Selected work

Apps you can download, and research you can check.

01 macOS Released

Vespertine

A Mac music player that shows you the whole signal path.

Vespertine plays stereo, surround and high-resolution libraries, including SACD images, DSD, and Dolby and DTS files. It traces each track from file to DAC, so you can see when playback is bit-perfect. It also runs a spectrum check that flags “hi-res” files that look like upsampled lossy audio.

I built it because I wanted to know what my DAC was getting.

02 iPhone On the App Store

HuskyHowl 2.0 coming soon

Northeastern athletics in one app, so you can stop juggling five tabs on game day.

Scores, schedules, teams and game-day updates for Huskies fans, with home-screen widgets and Live Activities. Version 2.0 is a ground-up redesign with scoreboard type and ticket-stub game cards, and it’s in beta testing now.

HuskyHowl is an independent fan app and isn’t affiliated with Northeastern University.

04 Research Technical report, 2026

Recovering 33.6 kbit/s from a Software Modem on a Packet-Switched Path

Software modems answering calls over VoIP lost more calls than they should have. We found out why.

I directed an AI-assisted investigation that traced the failures to a miscalibrated carrier-loss watchdog inside a closed-source modem datapump. The fix works at link time and leaves the vendor’s object file untouched.

Who did what: Claude Code did the reverse engineering, implementation, experiment design and analysis under my direction. I set the goal, ran the modem hardware and held the work to a standard of evidence. Appendix A of the report spells it out.

    Device integrations

    I added purifier support and a filter-life sensor to the community Dreo integration, plus a fan preset icon. Both pull requests merged in October 2026. I also keep forks for Govee and LEDnetWF Bluetooth lights.

Outside class

  • Hi-fi audio

    I care what happens between the file and the speaker. Vespertine started as a way to watch it happen.

  • Telephony history

    Modems, fax, pagers and office phone systems. I like old protocols, and I like making them work on networks built decades later.

  • Aviation

    Flight sim, a drone pilot certificate and a few tools of mine that read FAA data.
