Ambisoft has been developing software solutions for over 10 years.
As the sole owner, Marek Publicewicz has completed over
across the U.S. and Western Europe.
I have a M.Sc. in Computer Science and excellent English skills.
With 14 years of experience in writing software, I have expertise in Ruby (Sinatra and Rails), Objective-C (iOS),
I specialize in solving complex problems using multiple technologies,
and I excel at completing every project quickly and with quality code.
What I can do for you:
- create a working prototype of your idea (both web and mobile),
- take over an existing project and add new features,
- refactor and clean up the existing codebase,
- perform audit on your existing project,
- teach you programming techniques via online code mentoring.
To guarantee great quality, I use as much test-driven development
as possible (pragmatically rather than religiously)
You can see customer reviews on my past work, and hire me through these platforms:
Marek was a senior developer on the Parkio team and 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 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.
My team and I were impressed with both with your work and with your communication. Really top notch!
Marek is the best employee/contractor I have ever dealt with. His response to requests is prompt, he never seems to meet a problem he can't solve and his solutions are ingenious. He thoroughly tests and debugs problems, makes great suggestions for improvements. He has great work ethic and integrity.
I would be more then happy to provide anyone interested in hiring him a more detailed recommendation.
Ambisoft delivered above expectations and below the required time.
Mark understands the project scope 100% and goes out of his way to accommodate the employer. He also comes up with solutions for problems that you may face with technology. I have worked with numerous freelancers in the past and Ambisoft is by far the most professional!
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.
The work he did was outstanding and he
reported very quickly with good questions, which show his ability
to think into the problem at hand. Highly recommended!
Great job coming through on a project that went up to the wire. Really appreciate your dedication and reliability.
This man delivers what he promises and then some! He's one of the
best programmers we've met in our 10+ years of experience in the
programming business. We like working with him very much.
We asked Mark to carry out this project very independently so minimal input (and time) was neccesary from our side. He is perfectly able to understand and execute complex tasks in terms of project requirements, SOAP API and Drupal architecture.
He delivered a perfect job, it could literally not be executed any better. We're using him again for our next project, definitely.
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.
kingeri works at a very high level. From the first pre-acceptance
emails where we discussed the scope and approach to the project,
to the final tweaks of the deployed system, kingeri demonstrated
that he is a developer with a head on his shoulders.
We communicated regularly about technical issues and it felt like
I was working with a collaborator rather than a contractor.
His assessment of the project was spot-on with the uncertainties
and difficulties pretty much where we (he) suspected they would be.
I will definitely work with him on future projects.
Top Worker. Fast, reliable, eager to help and sugest better ways
to improve the end result. Excelent, fast and clear communication.
I have used him several times in the past and will continue
to use in the future. Thank you Mark.
If I could rate Mark at 12 I would do so. As a first time user of
Rentacoder, I could not be happier with Mark"s expertise and the service
he provided. He excuted the work with speed and quality. He made
this a very easy process and I"m extremely happy that we worked
together on this project. I highly recommend Mark
Excellent worker, very participative in findind solutions and
helping client. This job was particulary difficult since it involved
upgrading a preexisting application without updated source code.
Extremely cooperative worker. Will use him again for next applications.
Excellent coding, very thoughtful, committed to doing a good job.
Kingeri did a great job. He created a very professional, complete
system which was well-designed and well-organized. His knowledge
and skills are excellent, and he created a script that will be easy
to manage and modify in the future. Most importantly, he
understood the needs of our users, which some programmers
don't focus on. He is a true professional.
Kingeri was superb. He is extremely skilled and knowledgeble,
hard-working, fast, and thorough. He codes using the best practices.
He takes pride in his work, and made sure the project was done
completely to our satisfaction. His skills are broad and deep,
so that every facet of our project could be handled with no problems.
Finally, Kingeri is also a great pleasure to do business with.
Thank you, Mark
A project with considerable amount of frontend and backend components.
Finished with way more features than i initially requested.
Has put serious thought on data model, implementation and algorithm.
Very nice job.
Superb job with postgresql and perl - an outstanding worker.
Very fine sense of humor too. A pleasure to work with.
He's installed bugzilla for us. another worker tried it for one
whole day but it didn't work. It only took him a few hours to install
AND hack it to add some new features. He's just a genius.
He has completed my project again. He is a thorough thinker. For
the sake of the project, he had written me a lot of functions that
I didn"t even ask for. I simply can't thank him more.
I wish he will only work for my projects hehe.
What seemed to be a simple project turned into one of those that are
like an onion. Each layer revealed more complex challenges and
produced more tears. Fortunately Marek was one of those rare
individuals that not only absorbed the added work load without
complaint but had the technical knowledge to overcome the problems.
I would highly recommend Marek not only because of his technical
ablity but also because of his integrity. Fred
Terrific programmer. Mark went above and beyond my wildest expectations,
asked questions I'd never thought of, and was able to handle changes
to the original project I hadn't foreseen. He was able to work with
an older version of some critical that I wasn't even aware of.
He'll definitely be my #1 choice to do any future programming.
Excellent excellent programmer!
Fast delivery of the project. Managed to deliver everything as
required and more. Definitely my port of call for future Postnuke modules.
Went above and beyond the call of duty. Writes efficient and portable perl.
He found the problem quickly and communicated extremely well.
