Featured in Washington Post in March 2013 Client Recommendations (LinkedIn & Upwork): "Marek has been our primary programmer for over 10 years. His work is superb. He has an amazing combination of skills and qualities that make him highly successful and effective. He is very smart and reads extensively to continue developing his skills. He is a hard worker and is willing to work long hours if needed to make deadlines. He is an excellent, organized communicator and is available every day, regardless of time zones. He is a renaissance coder, meaning he has a huge breadth of knowledge in many many languages and platforms. He has a keen business sense and will approach all coding with a great understanding of flexibility and scalability for future business needs. Most of all, Marek's code is clean and well-structured. This is critical if you expect your software to last through future revisions and iterations. He does not take shortcuts. He develops a solid foundation, adheres strictly to MVC structure, and produces code that is clean, professional, reliable, and extensible." "Marek and I worked together on a very large PostgreSQL-based database application. At first, I had the ideas and Marek had all of the execution. But as we worked more together, Marek was increasingly coming up with new ideas to do things better and faster than I had considered" "It's a pleasure to work with Marek. He has top programing skills and will deliver top quality job. He is very professional and customer oriented. He understand quickly and precisely the needs and will advise you or make propositions if necessary. He know the importance of deadlines and be on time and on budget. He is always available and can work under tight deadline if necessary. I strongly recommend him." "Mark is #1 on my list of coders. He is a tenacious in his ability to get things done and his solutions are excellent. He is also excellent at trouble shooting problems and super responsive. He communicates effectively and keeps me well informed. My only regret is not having enough work to employ him full time" "Marek worked with us in late 2009 to completely rewrite our website using a new platform (Ruby on Rails) according to specific requirements. He did a fantastic job of pulling everything together, was communicative throughout the entire contract, and was very willing to work with us after the job completion to ensure that we were entirely satisfied with his work. It was a pleasure working with him and I would eagerly do so again in the future." "I met Marek in my home town, Mountain View, California a few years back when he was visiting the US. Over the years, we have also developed a very cordial and fruitful professional relation. He is not only a highly competent software developer with vast expertise covering many areas of software technologies, but also a pleasure to do business with. His technical competence is beyond doubt, and his pleasant personality, intelligence, prompt responses and attention to his clients, and high quality work are what make working and doing business with him always an enjoyable experience. My startup's user facing Web project has won quite a few praises so far from many parties. Marek's contribution and participation in said project are definitely important. I enjoy knowing him both as a person and as a honorable fellow professional, and will recommend him to anyone seeking his consulting services without reservations" "Marek built major pieces of our enterprise transportation product. He's smart, motivated, deeply knowledgeable across the entire web stack, and a consummate professional about his work. Great decision-making skills with a strong sense of practical tradeoffs. Highly recommended as a developer, project lead, or entrepreneur." "Marek did great work for us on BetterPPC - he delivers on time and on budget."

    I'm mostly focused on efficiently making small web applications for personal, rapid prototyping, internal-use only, MVP or proof of concept purposes. Some of my past apps have been converting "spreadsheet apps" into web apps, and web apps that import/export spreadsheets. I build my apps with a strong emphasis on function over form, as I'm more of a backend developer. This means that the apps have a simple appearance, but they get done quickly enough. Some of the features I've implemented for my own and client's apps have been: - Play different sounds depending on response from server - Import data from Zoho Docs (via API) - Import data from Google Docs - Import data from an Excel file - File downloads (for the user or for data import to server) - Geo-caching via Ruby Geocoder gem and Geocod.io, find the nearest address in the database to a user - Background Job Scheduling. Useful for complex calculations or things that can wait, so the user doesn't have to. - Send emails via MailGun - Created a Ruby Gem - Data import automation via Zapier - Data searching/filtering/sorting via AJAX (no page reload) - Search, Sort and Paginate via Ransack and Kaminari gems - Automated testing and specs with Rspec and Capybara. Background: I learned Java and C++ while getting my associate's degree. I then learned Python through Udacity's online courses, and used that for a couple years while researching algorithms, data structures and the hard problems in computer science. In the last couple years, I've been putting my programming skills to work towards becoming a full stack web developer. While I'm familiar with front-end work (CSS/HTML/JavaScript) and use them often, my previous programming experience makes me stronger toward back-end work.

What Is GitHub and Why Should Your Digital Team Use It?

Git and GitHub have completely changed the way we work in web development. They provide a centralized, cloud-based location to store, share, publish, test, and collaborate on web development projects. Git revolutionized version control—crucial when you have more than one developer working on a project. GitHub has added a staging platform that lets developers share prototypes, collaborate on projects, edit and build upon each others’ code, and give stakeholders a chance to take in-progress work on a test run.

Boiled down, Git is a web-based platform for working on projects, and GitHub brings those projects to life.

In this article, we’ll look at the basics of how each works and how they’ve helped to shape the workflow of digital teams like the ones built here at Upwork.

The basics of Git

Git is used by programmers, developers, and designers to store projects and keep track of changes to their files. It’s a cloud-based server that’s revolutionized real-time collaborative work between digital teams.

When software is referred to as open-source, it means it’s been made available to download for free—usually on GitHub. Just download the code and start using it, or building onto it.

Other reasons why developers rely on Git:

  • Collaboration made simple. A programmer uploads code to Git, where other developers can access it and edit it, isolated from each other and with all versions kept intact. Git takes away any confusion with having multiple people work on the same file at the same time.
  • Version control made easy. Every time edits are made to code, Git takes a snapshot. This tracks all the versions of a project along the way, saving a previous snapshot each time the file is saved in its “current state”—this is called a commit. Snapshots also let you revert back to old versions if something “breaks.”
  • Git has three main areas that are uniquely designed to give developers lots of control over workflow:
    • A working directory, which contains current states of files. Numerous developers can access a directory when they’re logged in, so collaboration is easy.
    • The staging area, which contains indexes of everything for the next commit, and any files that have been added or edited since the previous save.
    • The Git repository, where new commits are added. A Git repository contains (a) all the metadata, (b) the files, and (c) a dedicated database that tracks versions of the project.
  • Branches are one of the most important parts of Git, and make collaborating and incrementally adding to code possible, and foolproof. Developers and designers can work on the same project in an organized way—especially digital teams with remote freelancers. In a branch, some or all of the code is isolated from the project so it can be worked on without affecting the master branch. That code can be experimented with and worked on, then either made into its own, new project, or merged back into the original branch. 

The basics of GitHub

GitHub is Git’s cloud-based publishing tool and hosting platform. It also has a desktop application for locally storing projects. With GitHub, you can:

  • Bring projects to life. Git repositories are hosted on GitHub and made “live.” This enables developers to post a site or application when it’s in development stages. By sending a link to a GitHub project, clients can easily test-drive a site in progress with functionality, rather than just looking at flat mockups.
  • Browse the most popular development projects. Browse GitHub for “trending” repositories—an interesting way to check out other developers’ work and check out “starred” projects that are recommended by GitHub staff members. Public repository files can be downloaded as zip files and saved locally on your computer.

On GitHub, you can Star, Watch, and Fork:

  • Fork: Make a copy of a project and start working on it yourself.
  • Watch: Get updates when changes are made to a project you’re following.
  • Star: GitHub’s version of the “Like” button on Facebook, it’s a voting system that enables developers to vouch for projects they think are excellent.

On the collaboration front, GitHub also lets team members set up the following:

  • Issues: These keep track of what collaborators are doing and lets them ask about bugs. Issues can be opened or closed once they’re addressed.
  • Milestones: Set these up and give collaborators goals to work toward.

Have a remote digital team? GitHub is for you

With an emphasis on speed, data integrity, and excellent support for distributed, non-linear workflows, Git is the gold standard for remote digital teams. Also, Git is convenient for working offline or without a VPN (virtual private network), making it easy for developers to work on the go and stay productive. For teams rapidly building sites and prototypes for customers, GitHub is an efficient, safe and seamless way to get projects reviewed, approved, and signed off on.
