JACEK GALANCIAK: RUBY/RAILS DEVELOPER, SOFTWARE ARCHITECT Hi, I'm Jacek Galanciak.

With over 15 years of experience in software development, I had an opportunity to tackle complex problems and gain experience in the following: microservices and asynchronous

ANALYZING, VISUALIZING AND OPTIMIZING JS BUNDLE SIZE IN In this article, we'll create a Rails app with a simple React, analyze the bundle size and try to optimize two common reasons for size

inflation.

JACEK GALANCIAK: RÉSUMÉ. FULL-STACK SOFTWARE ENGINEER. Sourcebits, Inc. Technical Architect (Ruby) 2011 – 2014. I was a leader of web development team working on a long-term project (used by the education system and military), helped other projects with architecture and engineering advice, worked on improving general engineering quality of web development department. WKHTMLTOPDF ON HEROKU: EVALUATING DIFFERENT INSTALLATION The easiest and most flexible way of rendering fancy PDFs is using HTML+CSS as your source. wicked_pdf and pdfkit, the most popular Rails gems, employ wkhtmltopdf under the hood to generate them. It seems that there are multiple options of running wkhtmltopdf on Heroku. This post will explore them, analyze their drawbacks and identify the most

reliable one.

SECURING DEPLOYMENT CREDENTIALS STORED IN HOME DIRECTORY The number 599 is just an example, run dscl . list /Groups PrimaryGroupID and pick a number that is not used by any other group.. Step 2: create the user. Make sure to run dscl . list /Users UniqueID to select a number that is not taken by any other user. In the below example, we'll use 499: JQUERY QUICKSAND PLUGIN Name Default Description; adjustHeight 'call' Adjusts the height of container to fit all the items, 'call' for automatically adjusting before or after the animation (determined automatically), 'dynamic' for height adjustment animation, 'auto' to set the value to 'auto', false for not doing absolutely anything about it (useful on responsive

PLAYING WITH TYPED COLLECTIONS USING DRY-TYPES Things that make Ruby a particularly enticing language can as well become its bane in context of large projects. Dynamic typing enables passing around objects and methods without caring about their type but also makes it unpredictable and requires additional code to coerce

proper types.

IMPLEMENTING DSL IN RUBY, PART 1: CSV IMPORTER Ruby is famous, among many things, for its beautiful domain-specific languages (DSLs). The popularity is well-deserved: everyone loves to use DSLs for their efficient, often declarative, description of intention with very little syntactic noise of typical imperative

implementations.

Remote Ruby, Rails, JavaScript developer; microservices, domain-driven design, software architecture. PLAYING WITH RUBY OBJECT MODEL: PROTOTYPAL INHERITANCE Wrapping up. Is prototypal inheritance any useful in Ruby? Probably not. Some people would say that skipping expensive constructors in favor of fast object cloning or opting out of costly method lookup in the inheritance chain and using local methods instead (cloned from the prototype) can have performance benefits, but that is a weak argument for any high-level language. JQUERY QUICKSAND PLUGIN Quicksand. Reorder and filter items with a nice shuffling animation.

ZED SHAW: 'RAILS IS A GHETTO' Zed Shaw: 'Rails Is A Ghetto' Posted by Jacek Galanciak on Jan 6 2008. Każdy programista Rails zna to nazwisko.

Na pewno dzięki temu jest coraz mniej osób, które uważają, że jest to język zbyt wolny do aplikacji webowych - Merb w końcu pokazał, że potrafi być szybszy niż pythonowi konkurenci (Django, Pylons), a PHP (także pod względem wydajności frameworków) to RUPY - RUBY & PYTHON CONFERENCETRANSLATE THIS PAGE RuPy - Ruby & Python Conference.

About Blog Switch to dark mode HI, I'M JACEK GALANCIAK I’m a Ruby gangster, JavaScript thug, software architecture hooligan and microservices mobster. Just because the industry keeps using silly words like ninja and rockstar, it doesn’t mean I can’t outdumb

that.

I'm a software engineer with a strong focus on implementing maintainable systems through modular design and clean architecture. With over 15 years of experience in software development, I had an opportunity to tackle complex problems and gain experience in the

following:

* MICROSERVICES and asynchronous communication in an EVENT-DRIVEN ARCHITECTURE (via RabbitMQ or other message queues) * DOMAIN-DRIVEN DESIGN in both tactical patterns and business domain

mapping

* mastery in RUBY and RAILS – started in 2007 with Ruby 1.8.5 and

Rails 1.2

* DOMAIN KNOWLEDGE in STAFFING, INTERNATIONAL PAYMENTS, e-learning,

and real estates

* REMOTE WORK: I'm based in Łódź/Poland and worked exclusively remotely for more than 12 years with companies from Europe, Asia and

North America

My primary way of giving back to the programming community is through my blog, but I also have some interesting OPEN-SOURCE work: * quicksand.js : 1.9k stars and 250 forks on GitHub. Create a delightful animation when sorting/filtering your collections * s3-directory-listing

: use AWS Lambda

functions to generate index.html with a clean directory listing whenever you change anything in your S3 bucket

* dotfiles : Not an

open-source project per se but contains my current tools and configurations that took many years to accumulate. Want to learn about a craftsman? Have a look around their workshop! I'm currently a LEAD ENGINEER at Pilot , a Y

Combinator-backed

startup where we create a more open world-wide job market. LATEST BLOG POSTS Securing deployment credentials stored in home
