Roman is a senior software engineer with 8+ years of experience. His earlier career progressed through developing in C/C++ (embedded), creating web services in Java, and building services for collecting and storing geospatial data worldwide. Then he joined Agoda to lead a group of engineers developing services for processing and storing hotel prices that handled one million operations per second. Roman is currently working for Motional, developing mapping software for self-driving cars.

Work Experience

Senior Software Engineer

2019 - 2021
Motional (Formerly NuTonomy)
  • Applied convolutional neural networks and classic image processing techniques, using OpenCV for extracting semantic annotations from 2D map images.
  • Profiled and optimized an existing web service to double its serving capacity.
  • Automated various manual operations, which reduced human mistakes and sped up operation cycles.
  • Mentored a team of ten people to rapidly improve their hard skills.
Technologies: Python, C++11, C++17, CMake, PostgreSQL, C#, C++, Web Services, Automation, Team Mentoring, Programming, OpenCV, REST APIs

Software Engineer | Team Lead

2017 - 2019
  • Designed and developed a system that handled one million requests per second.
  • Reduced the load on the internal monitoring system by three orders of magnitude by catching and fixing bottlenecks in the client libraries.
  • Reduced the number of missed on-call phone calls by creating an on-call Slackbot.
Technologies: Scala, Couchbase, Apache Cassandra, Microsoft SQL Server, Docker, Docker Compose, Python, Programming, REST APIs

Software Engineer

2015 - 2017
  • Created an automated pipeline for importing geodata from OpenStreetMap.
  • Developed a geosearch API for querying the imported geodata.
  • Created and maintained continuous integration pipelines.

Technologies: C, C++98, Java 6, Python 2, Python, C++, Java, Programming, REST APIs

Remote-controlled, Self-driving Car
A toy remote-controlled, self-driving car that can perform simple mapping and manual navigation functions. I am developing this personal project as a playground for learning new skills and technologies.

Advanced Lane Finding
My goal in this project was to write a software pipeline to identify the lane boundaries in a video. The project was a milestone in the Self-Driving Cars Engineer Nanodegree on Udacity, and I used OpenCV and Python 3 extensively.

Traffic Sign Recognition Program
I used deep neural networks and convolutional neural networks to classify traffic signs in this project. I trained and validated a model to classify traffic sign images using the German Traffic Sign Dataset. After training the model, I tested it on images of German traffic signs I found on the web.
