About Sergen

Need a Computer Vision or Deep Learning specialist who doesn't just train models but actually ships them?

I build production-grade perception systems end-to-end; from data pipeline and model architecture through to optimized inference on embedded hardware. With nearly 4 years in automotive AI, I bring the rare combination of ML research depth and real deployment know-how.

What I typically take on:
— Design and optimization of real-time CV pipelines (6DoF pose estimation, segmentation, object/keypoint detection)
— Multi-task architectures and domain-adaptive training frameworks (synthetic-to-real)
— Hardware-aware model optimization for edge inference (ONNX export, runtime validation)
— Camera calibration, 3D–2D projection consistency, and geometry-aware training
— Prototype to production: from training script to deployed, validated system

What sets me apart: I have a peer-reviewed publication in out-of-distribution detection and work daily at the intersection of research and production — where many ML engineers stop, I'm just getting started.

  • Aptiv
    Computer Vision & AI Research Engineer
    AUTOMOBILE
    July 2022 - Today (3 years and 11 months)
    Wuppertal, NW, Germany
    -Own end-to-end development of a deep learning–based Driver Monitoring System (DMS) model, including alignment of Python training and C++ inference pipelines to ensure production consistency
    -Drove significant KPI improvements across the DMS model, enabling production-level maturity and improving downstream features such as drowsiness detection
    -Replaced a classical pose estimation algorithm with a custom neural network architecture using PyTorch, achieving ~30% inference runtime reduction on target embedded hardware while maintaining accuracy
    -Built domain adaptation training framework bridging synthetic and real data, improving target-domain KPI by ~40%
    -Engineered multi-head neural network unifying sequential tasks, replacing a two-model pipeline and rule-based post-processing with a single forward pass and reducing end-to-end latency by ~15%
    -Implemented coordinate frame transformations and intrinsic parameter adjustment to ensure 3D–2D projection consistency under image undistortion, augmentation, cropping, and rescaling (OpenCV)
    -Conducted semantic segmentation research mapping monocular camera inputs to structured spatial representations
    -Generated semantic segmentation training labels from LiDAR point clouds via voxelization and DBSCAN clustering
    -Architected a multi-task training pipeline with masked loss formulation and GradNorm-based weighting across disjoint label spaces, enabling stable joint optimization and shared backbone representations
