Experience
In industry, I’ve worked on the sensors and SW platforms that drove 18-wheelers weighing 40,000 lbs at 65+ MPH autonomously. I’ve also worked in Academia researching autonomous vehicles, teleoperation, and LiDAR sensors.
Though I love working on challenging problems in Software, I also enjoy the chance to get my hands “dirty” building cutting edge compute systems, toying around with new sensors, using microcontrollers, 3D printing, and so forth.
Here’s some interest areas based on past experiences of mine:
Perception
- object detection and tracking via LIDAR, using both geometric and learning based methods
- detection-track cost functions
- track motion prediction, filtering
- LiDAR pointcloud filtering, projection, voxelzation
- state estimation, Kalman Filters, kinematic / dynamic modeling of vehicles
Sensors 🎥
- sensor sriver architectures
- IMU, GPS, wheel odometry and sensor fusion
- fixed pattern scanning LiDARs, random-scan pattern LiDARs
- stereo cameras, thermal Cameras
Control ⚙️
- lateral control algorithms, (MPC, LQR, PurePursuit, etc)
- longitudinal control algorithms, (PID, MPC, lookup tables)
- dynamic modeling, offline/online model parameter estimation
- linearization of non-linear dynamic models, look-up tables
Platform SW
Everything between the Hardware and Autonomy layer is crucial for reliable robotics! Hot take, but I think that we are often unaware of how small things in this layer can have big impacts upstream.
- Precision Time Protocol (PTP) for Time Synchronization, GNSS disciplined oscillators, estimating time inaccuracies
- sensor driver architectures, fault tolerance, diagnostics
- multi-socket CPU architectures & IO flow optimizations
- OS build systems, SW Provisioning, A/B update schemes
SW / Tools 🛠️
Software and Tools I like using:
- python, C++
- Docker, docker-compose
- ROS
- simulators – Gazebo, CARLA, MATLAB
- data analysis – Jupyter Notebooks, numpy, pandas, scipy, sklearn
- Linux, Ubuntu, bash scripts, command line tools, building custom tools
- CI / CD, Jenkins

Photography
I’m not a photographer. But I have some cool photos, or at least I think they are !
