I am Serhii. I am based in Zaporizhzhya, Ukraine, Europe. I am a Full Stack Software Engineer, I work full-time remotely. I work with WordPress/Web, Android, and iOS development. Accordingly to my hourly rate - I'm working fast and qualitatively. So, with me, you will save your time and money.
My past long-term clients were: the UK cryptocurrency startup (2018) and the Netherlands hosting provider "Snel.com" (Web) (2018). Also, I have been the Android developer at the UK marketplace startup (2017-2018) and the web developer at the Swedish healthcare startup project (2017-2018).
I have a Master's Degree in Computer Engineering and work experience background.
Now My main skills are Android Development with Java, iOS Development with Swift. Also, I work with Web (JS, jQuery, CSS, HTML, Twitter Bootstrap, WordPress, PHP).
I work with mobile development since Fall 2017. I work with Java since 2012, with the Web since 2013, with Android and iOS since Fall 2017.
I have a plan to improve my skills and experience. Now I improve my skills in iOS development with Objective-C and Android with Kotlin. Also, in my plan, I want to get experience with Play/Java framework, RoR, Django/Python, Go, React and Angular. So if you have projects with these technologies, I can work with you as a trainee/junior developer.
4+ years I work as a web developer in Yolyas Systems, Redwerk, and YolitNen teams and now I work full time remotely as a freelance Software Engineer. YolitNen is my personal brand - one person company.
My skills and Experience:
+ WordPress: I made a lot of websites, fixed tons of bugs and created new plugins and themes. I like coding with WordPress, not just to click with a mouse. I created the useful plugin for the multilingual Amazon wholesaler, the plugin for the trading on different Bitcoin and altcoins trading platforms (Binance, Bittrex, Bitfinex APIs and other). I developed a few custom modules for BeaverBuilder plugin, Visual Composer. I worked with WoooCommerce and created custom endpoints.
+ Android, Java: I completed 3 projects: the app for the online marketplace with Firebase, the webview app with custom intents and notifications, the focus calculator app with secrets (since 2017). With Java Servlets and JSP, I made simple web apps and web services (JAX-WS, JAX-RS) (2013-2015).
+ iOS, Swift: I made the app like Pitch Perfect app of Udacity course (since 2017).
+ PHP: I made several backends for web apps, mobile apps and admin dashboards. I worked with pure PHP: functions and OOP with MVC structure (since 2014).
+ Ruby on Rails, CoffeeScript: I took part in developing the big enterprise system (2016). I have a little experience but I can learn.
+ Python/Bottle framework, MongoDB: I created the backend for the mobile app to store data and upload images (2015).
+ Windows Phone (C++): I developed an image comparison app to compare images from one place. I used the OpenCV library (2015). Also, I developed the app for the lottery club on C# (2016).
I am open to learning new technologies for your projects.
I am a freelancer since 2014. Now I make my own products too. There are a few SaaS projects and plugins for WordPress (search on Envato: YolitNen Labs and YolitNen Labs Pro).
I have experience in using Trello, Asana, Slack, Jira, GitHub, BitBucket, GitLab, Heroku, Google Cloud, Vagrant and other tools and services.
I work with different methodologies: Waterfall + Scrum + Kanban.
My time zone is GMT+3, I am available 9 am - 8 pm Mon-Fri. But I can work during your time zone.
I have more skills and abilities, I will use all of them in your project.

Very good and professional.
Serkhi did some amendment work for me on wordpress. He made the seemingly impossible, possible when so many other developers failed on my request. Highly recommend him!
Thank you for the nice feedback, please feel free to ask me more help.
Very professional...The job was done quickly with no fuss.
Thank you so much
Once again Serhii has completed my task to a high standard.
I am very happy with his work on this project, and he even managed to finish this earlier than was expected.
Thank you, David. I hope to work with you again.
Serhii was very professional throughout this whole process and met all of my expectations to complete the task.
This was quite a complex task which required a lot of JAVA / AJAX expertise and customisation, not only to my site but the Wordpress Plugins which I use. Serhii was unfazed by this and even set out to make an additional plugin to make it easier for my customisation to the site when needed.
I intend to use Serhii's excellent skills and knowledge again for any future tasks I have for my site.
Thank you for your complex and interesting tasks!
Thank you! Everything is good!
Thank you! Nice work done.
