SELECTED SYSTEMS
THE WORK
Four public projects. Each one built around real data, explicit constraints, and an inspectable technical argument.
Transform a GPX route and elevation data into an interactive terrain artifact.
Turn a source tree into a queryable, evidence-backed architecture graph.
Serve a race session as a time-series store that both charts and agents can query.

OPERATING PRINCIPLES
HOW I BUILD
MEASURE THE REAL SYSTEM
Production distributions, traces, failure modes, and representative data beat architectural theatre.
MAKE EVIDENCE QUERYABLE
Graphs, typed contracts, telemetry, and deterministic tests turn understanding into infrastructure.
SHIP THE SMALLEST SOLID THING
A narrow production-grade loop creates more leverage than a broad demo that cannot be trusted.

WHAT I WORK WITH
THE STACK
Eight years across languages, cloud platforms, and the messaging and observability tooling that keeps distributed systems fast, traceable, and honest.

EXPERIENCE
From on-device ML to platforms serving millions of connected vehicles.
Senior Staff Software Engineer
Stellantis · Connected Services
Merging two decades of divergent FCA and PSA APIs into a single connected-services platform. I set the technical direction for 100+ B2B and consumer services, made the fleet observable with OpenTelemetry and ELK so millions of vehicles can be traced and debugged in production, and moved delivery off TeamCity onto GitHub Actions — releases stopped being events and became routine.
Staff Software Engineer
Stellantis · Connected Services
Joined to turn a green-field team into an organization. Grew it from zero to 20+ engineers, wrote the developer-experience and delivery standards it still runs on, and helped ship the Jeep Avenger connected-services launch across every domain it touched.
Technical Lead
FCA · Connected Services
Owned the telemetry platform ingesting live data from 10M+ vehicles, and wired the car into the world around it — EV charging networks, mapping providers, ecosystem partners — while trimming the AWS bill through architecture the scale finally justified.
Software Engineer
Concept Reply
Built the cloud-native backbone for Grohe's smart-home ecosystem: 100K+ connected devices, their telemetry, device management, and enterprise integrations. On the side, I delivered a Beretta Android app that turned raw performance data into guided, real-time training.
ML Engineer Intern
Docapost · Nice
Started where the data was messiest: an on-device model classifying documents in real time under tight constraints, paired with a semi-automated labeling pipeline that cut manual annotation roughly in half.

OFF THE CLOCK
WHERE THE WORK COMES FROM
The projects aren't separate from the hobbies. The mountains and the night sky are where the problems start; the repositories and the writing are where they end up.
ALTITUDE
ALPINE TREKKING
The Alps are where the terrain work started. Every GPX track I record is elevation, slope, and forest cover waiting to be sampled — which is exactly what Ridgeline turns into a 3D artifact. The mountains are the field test; the code is the souvenir.
SIGNAL
ASTROPHOTOGRAPHY
Astrophotography is telemetry with a longer exposure: stacking faint signal out of noise, trusting your calibration frames, and staying honest about what the data can and can't show. The same instincts behind a clean night-sky image build a trustworthy race-telemetry pipeline.
