Python/Machine Learning/Deep Learning Expert

Hi everyone. My name is Nguyen Van Tam. I'm from Vietnam, a beautiful and peace country. At present, I work as a Python/Machine Learning/Deep Learning Expert. I have over 3 years of rich experiences in this field. I have done many Computer Vision projects such as Face Recognition, Object Detection, Object Segmentation. I'm strong at Python, Sklearn, Matplotlib, NumPy, Pandas, Tensorflow/Keras and Pytorch. Hope we can be in touch someday.

About the project.
The client required to convert the original Tensorflow 1x source code to Tensorflow 2x version.
Skills requirements:
- Tensorflow 1x, Tensorflow 2x
Model Based Deep Learning Architecture for Inverse Problems
The client wanted to write a Python script using OpenCV to scan images. The script must detect all boxes in the images and count number of ticked boxes.
Paper Scanner using OpenCV Python
About the project
The employer wanted to learn how model scaling affects in knowledge distillation.
Knowledge distillation is a way to a small model distill knowledge from another well-trained cumbersome one. Therefore, the small model will be able to produce comparable results.
Model scaling means scaling up or down number of filters/layers of model.

The project requirements as follows:
1. Must be written in Tensorflow.
2. Train ResNet110, DenseNet, as teacher model.
3. Train ResNet18 from scratch and as student model to observe how knowledge distillation works.
3. Model scaling experiment.
Knowledge Distillation and Model Scaling Experiment
About the project
The employer wanted to build a Mask RCNN model in Pytorch for object segmentation.
The project requirements as follows:
1. Must be written in Pytorch.
2. Train on his custom dataset (videos were recorded by flycam).
3. Object direction tracking.
4. Clean and readable code.

The object segmentation part is actually not hard as it seems. I have built a Mask RCNN model with ResNet50 as backbone. The model reached 0.34 COCO mAP after 50 epochs.
For object detection tracking thing, SORT (with Kalman Filter) algorithm was used. Movement history of objects were kept. The final step was to calculate the direction based on them.

This guy is incredible!!! The best there is! Super professional with very high working ethics , I ended up giving him a 50$ bonus. I needed to setup a machine learning environment and to compile and build everything from source: cuda, cudnn, opencv, tensorflow , and pytorch. This is a very unpleasant task which consume a huge amount of time. He did a great job and didn't stop until I approved everything. Highly recommended!
