Code & contours.

I'm Gwendal, a CS student at UTT building data-driven things — pipelines, dashboards, the occasional model. The other half of my week is spent on rock and bike.

01 / 2025Data Engineering
DataFlow
Real-time pipeline ingesting 50k events/sec from IoT sensors into a distributed warehouse.
→ Reduced p99 latency from 4.2s to 180ms by replacing batch jobs with micro-batching and a custom partitioning scheme.
PythonKafkaSparkClickHouse
02 / 2025Mobile App
Crux
Offline-first climbing logbook with ML-powered grade prediction from accelerometer data.
→ Grade prediction reaches 87% accuracy on 6a–8b range. Syncs to a shared leaderboard when back online.
React NativeTensorFlow LiteSQLite
03 / 2024Backend / API
Velox
GraphQL API serving a cycling community platform — route planning, segments, social features.
→ Handles 1.2M daily queries with sub-10ms median response. PostGIS powers snap-to-road and elevation profiling.
GoPostgreSQLPostGISRedis
04 / 2024DevOps / Tooling
Sentinel
Internal observability dashboard aggregating metrics from 12 microservices into a single pane.
→ Cut mean-time-to-detection from 18 min to 3 min by correlating deployment events with error rate spikes.

Looking for
Spring '27 internship.
Data engineering, ML applications, or anything where a problem can be modeled with a good schema and a few well-shaped functions.
