EXPERIENCE

    I have 12 years of experience in software development, with first published freeware product back in school times. Of this, about 5 years strictly commercial, including:
  • Toptal.com - Web & Mobile development
  • Imagination Technologies - working on OpenGL ES ray tracing extension and hardware ray tracing driver for PowerVR
  • Neurosoft sp. z o.o. (Poland) - OCR-ing registration plates of cars
  • Linkbook Poland sp. z o.o. (Poland) - Android programming
  • Atablash LTD (United Kingdom) - Android and iOS programming, self-publishing
  • Wrocławski Portal Informatyczny - writing articles
  • Vratis sp. z o.o. - implemented encoding of medical imaging video using FFMPEG; implemented some linear algebra algorithms to remove alglib dependencies


ACHIEVEMENTS
  • 12th place in Algorithmic Engagements 2015 (also 14th in AE2014), organized by University of Warsaw and Google
  • Got ~60k downloads of my paid mobile apps


PROJECTS
  • J-Fizo (2014) - insanely hard puzzle game for Android / iOS - the idea came from automata theory, theoretical computer science. Includes level editor.

  • • Facebook integration - authentication, custom stories for each level
    • Common platform independent code in C++/OpenGL ES

    Android client:
    • OpenGL ES
    • Java, C++
    • Android NDK / Java JNI

    iOS client:
    • OpenGL ES
    • Objective-C, C++

    Server with leaderboard and player statistics:
    • Django
    • Python, SQL
    • Nginx, uWSGI
    • PostgreSQL
    • HTML / CSS / JavaScript / jQuery






  • Magic Butt (2012) - interactive female buttocks simulation for Android (as a live wallpaper). Also 3 other similar apps, including one for iOS.
• OpenGL ES
• Java
• Android SDK
• Eclipse
• Accelerometer, multitouch
• Some gaussian-shaped masks
• A tool to export image masks to custom file format
• Some high-pass and low-pass filtering
• Some interpolation

Also in modified versions with cats and breasts:
• Frame-based blended animation.
• Gyroscope used for 3D quaternion rotation.
• Simple ragdoll physics for the hanging necklace.
































  • Mandelbox (2011) - real-time raytracing of fractals, e.g. mandelbox, a beautiful n-dimensional fractal discovered in 2010.

    • nVidia CUDA
    • C++
    • Visual Studio
    • Raytraces discretely using given function for testing points in space (inside/outside of fractal)
    • Coloring based on selected branches in point test function
    • Ambient occlusion-like effect









  • CSG (2013) - real-time constructive solid geometry on triangle meshes.

    https://sites.google.com/a/atablash.pl/cv/home/cutworld.png


    • Boolean operations on solids (union, difference, intersection)
    • Infinite adaptive terrain
    • Single-precision floating point arithmetic with extensive geometry fixing (transition to higher precision makes artifacts nearly impossible for random tests)
    • Binary FBX loading
    • DirectX, DirectWrite
    • On the left: 3 round objects cut from the ground
    • I'm working on the next version based on new idea







  • Jim in Space (2015) - a simple physics-based puzzle game prototype made with Unity.
  • • Idea for the game, music and assets by Kamil Wolter
    • Unity 5
    • Some real-time by-vertex deformations of the balloon
    • Play the game prototype here!
       (Shadows don't work in Web Player)
