ABOUT ME
iOS Developer striving for the cleanest code possible
iOS Developer striving for the cleanest code possible

Hi, my name is Tomáš! You can try to pronounce my name (Tomaash) but I usually go with the English Thomas. I love making iOS apps and I knew I want to do it for living as soon as I bought my first iPhone. That was a long time ago and now I have almost 5 years of professional experience. During my time I coded many apps that are successfuly published in AppStore. I have also lead a small team of iOS Developers and mentored the junior members. I have talked on various events (mDevCamp, mDevTalk) about testing and benefits of a clean code.

Currently, I do the best in:

★ iOS
​ ​ ☆ Swift 5 (Advanced swift knowledge)
​ ​ ☆ Objective-C
​ ​ ☆ All things reactive - ReactiveSwift, RxSwift, ReactiveCocoa
​ ​ ☆ fastlane 🚀
​ ​ ☆ Clean code, system architecture and testing
​ ​ ☆ XCTest, Quick, Nimble
​ ​ ☆ Build automation
​ ​ ☆ Provisioning
​ ​ ☆ Autolayout
​ ​ ☆ Firebase
​ ​ ☆ CoreData, Realm
​ ​ ☆ Performance, Memory management
★ React Native
​ ​ ☆ Hybrid applications
​ ​ ☆ Native bridging
★ Git​ ​
​ ​ ☆ Basic git usage
​ ​ ☆ Hosting services (e.g. GitHub, GitLab, BitBucket etc) ​ ​
​ ​ ☆ Best practices for working in teams (pull request, feature branches, etc..)​ ​
★ Javascript
​ ​ ☆ ReactJS
​ ​ ☆ Redux, Router, ...
★ HTML / CSS
​ ​ ☆ Bootstrap
​ ​ ☆ Quick CSS fixes
★ PHP
​ ​ ☆ Web scraping
​ ​ ☆ Nette framework
​ ​ ☆ Magento
​ ​ ☆ Wordpress
​ ​ ☆ APIs in php
★ Code Review ​ ​
​ ​ ☆ Code review for Swift and Objective-C
​ ​ ☆ Best practices and architecture tips
★ Computer Vision
​ ​ ☆ Using OpenCV
​ ​ ☆ All kinds of recognition

My strongest suite is iOS but I have also a long term experience in Web Development and I keep an eye on new trends making sure I never fall behind. I am very good at solving problems and I enjoy helping people out.

Few extra things so you get to know me better:
★ I love travelling and spent the last year going through most of the countries in South America
★ Once upon a time I wrote a joke programming language that went viral
★ I care about the rights and well-being of unicorns (http://whostolemyunicorn.com/)
★ I've visited 42 countries so far
