Mariusz Wyrozębski
I discovered Ruby in 2008. Since then I’ve
successfully delivered a range of projects with both
onsite and remote teams acting in roles from senior
developer to tech lead.
I’m extremely excited by new technologies and
solutions they create. I love being involved in the
business side of the company and staying in contact
with clients and stakeholders. I’m a big fan of
remote working, I believe a remote team can be more
successful then an onsite one if managed correctly.
Wait… but what other people say about me?
all remote jobs!
Great, insightful strategist with top class communication skills. Broad-minded, open minded and
customer-service oriented software engineer. I enjoyed working with him on the various projects we
took on.

Mariusz is a passionate, motivated, and experienced software engineer. Project after project, he has
blown away my expectations with ability to deliver extremely well engineered Rails applications. I trust
his judgement and continue to rely on Mariusz's unfailing ability to deliver working / beautiful software.
Terrance MacGregor
Founder, CTO at LawIQ
I highly recommend Mariusz and his team at Red Warrior Studio. He is extremely talented and
personable with a strong depth of knowledge in rails development.
An overall great guy, if you're looking for some ruby development work done, I wouldn't hesitate to hire
Mariusz and his team.

June 2013 - March 2015
I’m a Ruby on Rails developer working on both backend and Angular
based frontend.
Try Catch is a recruitment company made by developers.
I’m one of Ruby stack experts that are evaluating code pieces sent by
other rails developers.
I’m providing Ruby on Rails development services and support for
Covintus clients.
I have been responsible for two startups: http://www.darkwebid.com/
and one internal tool for TEDCO consultants. In the meantime I have
been creating internal tools suplementing reports from Harvest time
tracker.
At the time when I was hired at ProFinda, the company has been tied to
outsourcing company services and processes. I have been there to
move those processes and create a new culture that could invite other
developers that would be hired next.
I tackled experimental and unconventional approaches to simple
problems and have been tasked with planning new architecture that
would better reflect the needs of our clients.
As processes stabilized we have been working with code reviews, TDD
and CI every day.
I have faced many challenges including building APIs for our matching
services, moving frontend logic to backbonejs, implementing saas
model. Apart of that I was responsible for chef recipes and server
maintenance for our engineyard based cloud.
I have been building Salesforce and Taleo plugins for sister product, that
I have built from just the idea of the CEO.
Bytelion
August 2011 - August 2013
Here I have been implementing startups with Ruby on Rails, Redis,
MySQL/PostgreSQL, Nginx, rspec toolkit and coolest of all Goliath. This
time was a big mix of small and medium sized projects that exposed me
to countless different decisions that had to be made. I have been
building startups mostly from scratch and integrating rails applications
with lots of payment services, but there were even those like TroopID or
parsing Tweeter feeds. Constantly learning and staying on the edge of
ruby technologies with special love towards Rails.
I have been tasked with most of the process around startups like client
interaction, converting requirements into user stories, planning of
iterations, then development, testing and some devops to deploy and
maintain all sites.

TopCoder
around 2004 - December 2009
I have grown here to become more like entrepreneur than developer. As
I recall I have always got difficult tasks and learned to not afraid of them.
Here I got the ruby on rails disease. Thanks for the great coaching I
have learned curiosity and persistence to stay on the very edge. Most of
all I appreciate the empowerment and ways of how the teams could be
led. I have been thrown into a mix of projects as Selleo is an software
outsourcing company. We have been working both with TDD and BDD.
It was my long awaited project management position.
I have gathered my first experiences as a team leader for a small group
of three. I have been responsible for product quality and bug fixes but
keeping an eye on the flow of development to meet its deadlines. My
other duties were to create user stories for developers from client
requirements, plan all iterations and make sure they are delivered.
TopCoder was my turning point in my career. It was first touch with high
quality code acceptance criteria. It gave me a glance on how detailed
programmers should be and how often just a bit more of the effort
makes great difference.
As TopCoder is an online comunity where developers compete with
themselves to deliver software I participated as a competitor and code
reviewer.
At some point I have been acknowledged and couple of times I have
been hired for internal clients outside of competions.
Even more references?
Someone said: You paid them well!
I wanted to recommend Mariusz as a great Ruby on Rails developer. He is keen to accept challenges
and proactively seeks ways to solve problems. He feels best working with new technologies. He is a
good listener and a valuable technical advisor. He easily gets adapted to new environments and has a
cheerful character. I am sure that he will help to leverage your team’s performance.
Arkadiusz Kwasny
CEO at Selleo
Over the past two years Mariusz has been a key member of our development team as a senior Ruby
developer. He has helped shape the architecture of our products and in fact built one from scratch, and
has worked well on independent projects that required thorough research and execution. Apart from
strong core Ruby skills Mariusz also has a great sense of UX and an appetite to learn new skills and
languages (i.e. Apex).
Roger Gorman
CEO at ProFinda
Mariusz has a unique ability to turn complex problem sets into simplified solutions through his
development skills, skills which are at a senior level and border on art. Another even greater attribute is
his ability to communicate early and often to avoid pitfalls in fast paced software development. I would
gladly have him on any team I am on now and in the future!
