implementing new features and refactoring some older parts of the codebase.

Contributing greatly to a Sonic Sleep app for iOS and watchOS - cannot share the
details, but it's a lot of high-tech proprietary stuff. Working with AVFoundation,
HealthKit, Websocket, Bluetooth, Airplay and other I/O frameworks to provide a
great insight into the sleep patterns of patients. Swift & Objective-C.

Taking ownership of the iOS app FindMe, working with Parse backend, refactoring legacy
Objective-C codebase, continuous integration via Bitrise.

I'm leading a team of three in an international environment, working with security technologies,
writing Swift code, messaging with Socket.io. We're developing a sophisticated HIPAA
compliant social network for physicians and patients - HealthLinx (now Teleon Health). My
key responsibility was to ensure quality codebase and fast delivery in a tight time schedule.
Deployments are done through Bitrise CI, task management in Trello. Fast iterations and regular
calls with client ensure the project always runs in the right direction. As our client was a health
startup, one of my responsibilities was to ensure security and privacy when handling sensitive
information.

From the beginning I was helping to shape the product, getting people on board, taking the
technical lead. We failed multiple times, but finally we created a sophisticated social
marketing platform and a social network.
The iOS app is written in Objective-C and common frameworks like UIKit, AFNetworking,
MapKit, CoreLocation, Core Data, Auto Layout, Google Analytics, Fabric etc. I also
developed custom image gallery, custom camera and photo editor using graphic card powered
filters by GPUImage. Custom graphics include social followers calculator graph views done in
CoreGraphics. The app is using Facebook and Instagram integrations. Continuous




integration is the part of the development process - at first it was Jenkins, now Bitrise. UI
Automated tests were crafted in KIF. Agile development, SCRUM, shipping to AppStore
almost every week the first year. I've also been responsible for the hiring process, growing the
team from 2 people in the beginning to 12 people. Style InCities app is available on AppStore.

Here I was part of a small app agency and I was involved in development of several enterprise
and AppStore, iPhone and iPad apps. My keen desire was to work with clients on the solution
and make sure the apps we made meet their requirements. One of the first projects was Galerie
Butovice, which is a shopping mall app. Using UI Kit, Core Data, Core Graphics for custom
pseudo-3d map of the mall with selectable shops which were rendered dynamically on basis
of the synchronized Core Data database. This app was designed to work fully offline,
including download manager for PDF versions of the magazine, database of shops and the mall
map and also public transport timetables.
Cribis Mobile app incorporates in-app purchases, restoring purchases, graphs, multiple
languages and multiple data sources, data recalculations via up-to-date exchange rates,
contacts, reminders, RSS feed, data caching, etc.
Hyundai Salesforce app perfects visual experience of Hyundai models on iPad, featuring
comprehensive car configurator, local database synchronization and custom media gallery.
mHostess is a fully configurable iPad presentation app which fetches the campaigns and
prezentations to the local database, works offline and submits batches of filled forms once
the internet connection is available.
Shopsel, Akční Ceny and Zlacnené are three projects from a single codebase. Apps feature
REST API data fetching, Core Data storage, Core Animation.
Apps I've created from start to finish myself: Akční Ceny, mHostess, Shopsel (iPad and
iPhone), Cribis Mobile, Hyundai iPad sales app, Galerie Butovice, Zlacněné and several
promotional iPad apps for Phillip Morris. Most are still available on AppStore. I also made two
HTML5 games in Cocos2d-x framework which are no longer available online.

I've cooperated on project Albert v Kuchyni for iPad. My key responsibility was to develop
preloading of pdf pages efficiently, and create new components that were using them
(gridview, table of contents previews). During that time I was improving my knowledge of
frameworks by studying the lecture material of a C193p course on Stanford University.

Republic.
I started creating games in Game Maker in my early teens, laying my hands on both 2D and
3D games development and graphic design. On high school I've gotten more professional by
co-working with Nifflheim Softworks and several individuals and producing variety of games.
Panzer Tournament is a LAN multiplayer top-down shooter with map editor, stunning
graphics and computer-controlled players (who even chat!). Interactive maps, variety of
weapons and environments, bot personalities make this game a real masterpiece. Visuals
include custom OpenGL renderings, post-screen effects, particle effects and animations. In
Panzer Tournament there are 6 game modes including 3 team game modes. Computercontrolled
players are very competitive and have several layers of reasoning - individual
combat, self-enhancement, chat and team goals. My own physics engine developed for this
game is also worth mentioning.
Inventor Arena is a 3D tank shooter with split screen multiplayer and vehicle editor. A game
that has been developed within 2 months on high school.
I was publishing the games on YoYoGames.com and other portals for free. Both Panzer
Tournament and Inventor Arena are still available at YoYoGames.com.
