The biggest part of my work was done in the field of CV. The performance and the size of DL models have always been the most important part.
Developed segmentation, classification, and object detection solutions for PDF Expert and ScannerPro, which run in production. One of the key ScannerPro algorithms was reinvented by my initiative. Also custom lightweight YOLO-like and UNet-like models were built from scratch using Keras. Another big task was to reinvent the pen-annotation tool algorithm for PDF Expert using computational geometry. Additionally, I conducted research in the field of NLP for Spark. Read DL course for Readdle employees.
Freelance project, December 2017 — February 2018
Implemented approach from “Attention is all you need” for machine translation using numpy and tensorflow, as a part of the project for translation web-service.
Autobrains.ai — Deep Learning Engineer, January 2022 — July 2023
Implemented from scratch SOTA lane detection algorithm(2105.13680) using PyTorch.
As a part of the object detection team, trained and evaluated models for different object detection tasks on a daily basis.
Implemented solution for sub-classification task on the intersection of classification, object detection, and transfer learning fields.
Work on an internal auto-labeling tool using big object detection networks, transfer learning and custom approaches for 3D configuration detection of vehicles. Worked with mmdetection.
I have BS and MS degrees in applied physics and math.
- Created a detection algorithm for the PDFExpert macOS app with 100% accuracy.
- Created a custom object detection solution that meets KPIs even with a very small dataset for an autonomous vehicle task.
- Implemented the "Attention Is All You Need" paper for a freelance project back in 2017.
