My journey in the world of software development has been marked by continuous growth and a passion for solving complex challenges. I've evolved from a Lecturer in web development to a Tech Lead Software Engineer, gaining expertise in various areas along the way. A significant milestone in my career was my role as a Senior Backend Developer / DevOps at Webedia GmbH. There, I not only mastered Ruby on Rails but also improved and configured recommendation systems, elevating user experiences to new heights. In another role as a DevOps / Platform Engineer at anynines, I excelled in automated PaaS management and introduced microservices architecture using Ruby and Golang. My knack for system automation and PaaS application support contributed significantly to the organization's efficiency.

Ruby on Rails developer with a designer background. Built my first website in 1997 Ruby on Rails since 2012 Works solely with “Boring Rails” (Ruby on Rails, Postgres, Hotwire, ViewComponents and TailwindCSS) stack.

I’m Ruby/RoR engineer obsessed with databases and automation. For 12 years I devote myself to the IT industry as (formerly) a technical writer, then a software engineer (10 years), incl. being a business owner and tech lead (since 2018). • I’m deeply familiar with Ruby and/or Ruby on Rails. Since 2014 I’ve been working on and building (incl. from scratch) a dozen of apps from huge monoliths to small apps, full-stack or API-only apps, and worked with versions 3.2–7.0 of Rails and 1.9–3.2 of Ruby; • Besides Ruby/Rails (and Sinatra, and Cuba), my strong points are Oracle & PL/SQL and PostgreSQL (incl. writing and tuning complex SQL queries), Shell scripting (from Bash with grep/sed/awk to Perl/Python/C), and User testing (Watir, Cypress); • I also have a several-year experience with JavaScript as well as React and Vue and I’m capable of talking with the frontend people in the same language as well as doing not-so-complex things; • I speak and write English fluently; • I worked in both enterprise- and startup environments; • I’m unbelievably initiative and enterprising and never-sitting-on-my-hands. I consider myself a well-equipped T-shaped engineer, and I’m tool agnostic and not constraining myself only with Ruby or Rails. For me tools are just tools to build products and work on challenges. Besides, since I treat product development as a single whole, I prefer to be not just a coder and executor, and not in a specific area, but my real power (and, inseparably, passion) is in a diversified approach to the product, that is, diving in the product/business realm, bringing and brainstorming new (or good old) ideas with stakeholders, implementing them on different levels, rethinking processes (of whatever it could be—product itself or development team), increasing the database (and not only) performance, doing/setting up/improving deploys, gathering use cases, breaking them down into test cases and then implementing e2e tests, trying to preserve any knowledge for the current and potential team members by writing structured docs, etc. I do love seeing a big picture and working on various levels of responsibility and parts of the product besides just typing the code, which is still basically the major part of my work. More details on the above or other things we can surely discuss tête-à-tête :)

I can help you with: Refactoring your legacy app into a readable and maintainable codebase Building your MVP in short time Building new cool features and fixing bugs on your app I can build your SAAS Using: - Ruby on Rails - ReactJS - React Native

12+ years building software, mostly with Rails. I consider myself a Rails generalist - someone who's good enough at multiple things but doesn't necessarily fit in standard corporate roles like front-end developer, back-end developer, devops etc. I do a bit of everything, and I love it. I prefer working with small teams, be it a small family business or an early stage startup.

For more than 8 years, I've worked on production Ruby on Rails applications of all shapes and sizes, from MVPs at tiny startups to large, legacy enterprise applications. I have deep experience using proven open source technologies that are built for productivity and offer long term maintainability, including specialized expertise in modern full stack Ruby on Rails (Hotwire, Turbo, Stimulus), PostgreSQL, Tailwind CSS, ViewComponent, and Phlex. I look forward to learning how I can contribute to your product or team.
