Yehonatan (Jonathan) Cohen — Systems and Firmware

yehonatan@systems ~

01 / IDENTIFY

Computer Science student in the Burnett Honors College at the University of Central Florida, graduating in 2030. I like getting to the layer most people treat as a black box, whether that is hardware, firmware, or a wire protocol, and making it do what I want.

02 / SELECTED WORK

// Systems in operation
Click to fly the globedrag to orbit, scroll to zoom, then W E T C B D M P H toggle HUD layers

WorldView

A real-time geospatial intelligence dashboard fusing live satellites, aircraft, CCTV, and seismic data over photorealistic 3D tiles, with shader-driven HUD modes. Running live above, click in and drive it.

TypeScript / Three.js / WebGL shaders / Google Map Tiles

TN3270 Web Terminal

A browser-based IBM 3270 terminal emulator (client plus a WebSocket-to-TCP proxy), shown connected live to my FASTER mainframe emulation over the real TN3270 wire protocol. The green screen above is the actual CICS sign-on.

TypeScript / TN3270 / WebSocket / Canvas
Same booking, five dialects

GDS Host Emulator

A multi-dialect GDS host emulator with cryptic-entry parsing, the full PNR lifecycle, pricing, queues, and ticketing. Switch dialects above: the same JFK/LAX round-trip booking is driven in each one's native cryptic. Calibrated against a live Galileo tenant, ~1,580 tests.

TypeScript / 5 dialects / ~1,580 tests
IPP / two terminals
server  npm run start:emulator
client  npm run start:client

Printer Emulator

A virtual network printer that speaks the Internet Printing Protocol end to end. It ships as two halves that run in separate terminals, the emulated printer and a client that drives it, so print pipelines can be exercised without hardware. Both traces above are real output.

TypeScript / IPP / AirPrint / HTTP
// Systems under the hood

UniFi Network Automation

A toolkit that programmatically drives a UniFi Cloud Gateway over the Chrome DevTools Protocol, with automated TOTP login, a loopback SOCKS5 tunnel, CSRF-signed API calls, and dynamic local-DNS record management.

Python / Node / CDP / UniFi OS

Private / hardware

Home Gateway Reverse Engineering

Reverse-engineered a fiber gateway down to its UART serial console and built a custom dashboard around its firmware web interface, with proper challenge-response authentication.
