Mechanical engineering, built around design, analysis, and proof.

I’m Ahmet Hamza Mülayim, a mechanical engineering student at Marmara University. I build physical systems, analyze how they behave, and increasingly lean on data — vibration signals, flight records — to understand them better. This portfolio is the real projects behind that, not a résumé.

Selected work

Projects that show engineering judgment, not just buzzwords.

Aviation Data & Systems

Live flight tracking, a delay dataset I built myself, and the model and comparisons built on top of it.

Aviation Data · Live · Jul 2026

Live Turkish Airlines flight globe

Where is every Turkish Airlines aircraft right now, and what is it flying?

130+Flights tracked live

Aviation Data · Pipeline · Jul 2026

IST flight delay dataset

Istanbul Airport has no public historical delay dataset — so what does one look like once you build it?

  • OpenSky + aviationstack joined on callsign
  • Append-only CSVs with quality flags
  • Collected daily by a zero-maintenance GitHub Actions pipeline

Istanbul Airport terminal from the air

Data story · aviation logistics · Aug 2026

Logistics of IST — the world's 8th busiest airport

84.5 million passengers, 327 destinations, and a terminal laid over abandoned coal pits. How Istanbul built the world's 8th busiest airport — the tender, the ground, the 29-hour move, the metro — with a satellite timelapse of the site from 2017 to 2025.

  • 84.5m passengers in 2025 — 8th busiest in the world
  • 327 destinations and 82,733 connections — the most connected airport on earth
  • 7,600 hectares of former lignite mines and 70 quarry lakes

Experiments & side projects

Built out of curiosity, not part of the mechanical engineering thread above.

A Concorde airliner on the ground

Web / Interactive · tribute · Jul 2026

Mach 2 — a homage to Concorde

A non-commercial fan tribute: the life story of the supersonic airliner, an honest look at whether it will ever have a successor, and an interactive 3D globe of its most famous flights.

  • Biography timeline, 1962 treaty to 2003 retirement
  • Interactive globe — pick a flight, fly the great-circle route
  • Balanced take on Boom's Overture and the XB-1

Web / Interactive · built for the love of it · Aug 2026

Web Piano — falling notes, real MIDI files

A browser piano you can play by hand, with a real MIDI keyboard, or by loading a .mid file straight from your computer — keys light up as they're struck, and colored bars fall from the top to preview what's coming next, the way piano-practice games do.

  • Full 88 keys, sampled piano sound, not synth beeps
  • Mouse, computer keyboard, or a plugged-in MIDI controller
  • Six pieces with real backstory built in, one click to play — or load your own .mid

Systems / Windows · own repo · Aug 2026

BiggerBrother — a traffic observatory for your own machine

Ties every DNS query and socket on Windows to the process that made it, via ETW — plus an in-browser request recorder that shows exactly which cookies your browser handed to which trackers. Local-only: no cloud, no TLS interception, nothing leaves the machine.

  • Per-process attribution: who talked to whom, and who owns the far end
  • In-page cookie/tracker capture without touching TLS
  • Per-process kill switch — drops an app's live TCP connections with Cut or Choke
