The most amazing...

...was working in a team of 4 implementing a complete real-time AR app —API, web app, iPhone app, and preprocessing tons of data (C++, Node.js, Amazon Cloud).

Employment

  • Computer Vision Research Engineer

    2016 - PRESENT
    Blue Vision Labs
    • Developed a TypeScript/Python pipeline using the Amazon stack—processing tons of data with S3, computing on E2, and storage with PostgreSQL.
    • Coded optimized Three.js (JavaScript) and the WebGL viewer—showing millions of objects in the browser.
    • Analyzed and optimized SQL queries over a large PostgreSQL database.
    • Dug into the SLAM system and adapted various open-source projects for internal usage, mostly using C++.
    • Reconstructed a dense point cloud; also did the comparing and tweaking (Python/C++).
    Technologies: C++, Python, ES6, PostgreSQL, WebGL

  • Research and Development

    Photoneo
    • Designed and wrote C++ highly optimized firmware for a 3D camera.
    • Wrote core computer vision algorithms in CUDA on Tegra TX1 in the firmware.
    • Designed and wrote a Qt user interface for a 3D camera.
    • Helped the Bonjour/Avahi network to discover connected devices; also designed and implemented the API and aided in the communication between the driver and firmware.
    • Created Gazebo physics simulations of bin-picking.
    • Designed the multi-platform (Ubuntu, Windows), built it (CMake), and deployed it (CPack installers).
    • Wrote the C++ programming for a real-time 32-bit Teensy microchip controlling mirror.
    • Designed and implemented various real-time APIs using C#, ROS, C++, and Halcon.
