Craig Koszewski · SVP, Head of FX Technology & Product Development @ Northern Trust · Chicago, IL
Trading platforms and technology roadmaps by trade. Guitars, bookcases, and machines that make other things by nature. Same discipline, different materials.
TECHNICAL BUILDS
Systems where milliseconds and data models matter. Platforms designed from the schema up, owned from whiteboard to production.
BUILD_01
High-performance retail trading platform
A retail trading platform engineered for speed and correctness. The core is its data architecture: normalized market and account state flowing through an algorithmic execution layer, built to stay deterministic under bursty, real-time load.
BUILD_02
AI-integrated electronics inventory
Hardware meets software: an inventory system for a workshop's worth of components, with AI-assisted identification and categorization so a drawer of mystery parts becomes a queryable database.
BUILD_03
Game tournament tracking system
A tournament tracking system that handles brackets, standings, and match history — built so organizers run events instead of spreadsheets.
BUILD_04
Autonomous multi-agent engineering team
A headless, autonomous agent hierarchy: five specialized agents operating as a private agile team — planning, architecting, building, reviewing, and shipping across Craig's projects. Fully self-hosted within his home network, working whether he's at the bench or not.
PHYSICAL BUILDS
The same precision, different medium. Toolpaths from Fusion 360, fixtures off a Bambu Lab printer, joinery mapped by CNC — technology in service of things you can hold, sit on, and play.
MAKE_01
Fusion 360 → CNC → Finish
A playable instrument that started as a parametric model. Designed in Fusion 360, the body and pockets precision-cut on a CNC machine — toolpaths doing what templates and routers used to, to tolerances they never could.
MAKE_02
Measure → Model → Install
Floor-to-ceiling built-ins designed around the room, not against it. Spatial design and structural woodworking working together: load paths, reveal lines, and scribed fits where drywall refuses to be square.
MAKE_03
Sketch → Joinery → Glue-up
Functional furniture with a job to do: hold a pianist steady for a few thousand hours. Proportioned from the instrument out, joined to outlast the piano it sits beside.
CAREER & CORE
One discipline, two workbenches.
Craig Koszewski is a Senior Vice President and Head of FX Technology & Product Development at Northern Trust in Chicago. His career is rooted in software architecture: he owns the technology and product roadmaps for his institution, making the calls on what gets built, how it scales, and why it matters. The systems under his name move real money in real time, which leaves no room for design by accident.
But the title is downstream of the actual identity: Craig is a maker. His personal time goes to bringing schematics to life — sometimes through a soldering iron, sometimes through a 3D printer, sometimes through an IDE. Lately that includes The Ark, a five-agent autonomous team he built and hosts on his own home network, so even his side projects have an engineering department. A trading platform and a CNC-cut guitar are, to him, the same problem wearing different materials: understand the constraints, design the structure, cut precisely, and ship something that works.
Relentlessly curious. Allergic to the ornamental. If it doesn't function, it isn't finished.
