Ma journée

Aujourd'hui j'ai eté a la maison de ma j'ai resté chez ma tante avec son chien... J'aime les chiens et le chats... En après-midi j'ai etudièé mathemathique les maths et la musique... Je voudrais aller en visiter France pour que je puisse visiter Paris et la Provence...

(J'ai étudié depuis quelques années mais ce n'est pas ma langue maternelle. Alors il est probable que j'ai fait quelques erreurs-- il faudrait consulter quelqu'un d'autre pour être certain) 

Today I stayed at my aunt's house with her dog... I like animals, in particular dogs and cats... In the afternoon I studied Maths and Music. I'd like going to go to France to so I can (technically "I'd like to go to France so I can visit Paris" is correct, but Americans would probably say, "so I can go")visit Paris...

Yo estoy con ma tia... Me gustan el perreo... En la tardes yo hay estudiado....

Introduction job experiences

Hi,

My name is Patrik and im  I am a Software Developer. I am working in the Slovak startup company, Nicereply.
This is my second job (job is implied by the word "position") position and im there I have worked there for over two years.

My first position was in with ("in" might be correct but "with" sounds better) Onlinehost. Onlinehost provided provides B2C webhosting services (I'm assuming the company Onlinehost still exists. "Provided" implies that it provided those services when you were there, but no longer offers those services). I was there as a co-founder with my a friend of mine ("my friend" is correct but "a friend of mine" sounds more formal). We were trying provide provided fast, secure and stable hosting services ("We were trying to provide" is correct, but implies that there's a possibility that you failed. I'm assuming you succeeded in providing those services). Im working I worked there as (insert the word "a," if there were multiple administrators and software dvelopers or the word "the" if you were the only system administrator and software developer) system administrator and software developer. My job was to create and maintain the whole of the infrastructure of our business including the analysis, design, implementation and maintain maintance of our information system.

While i I worked on our business, im was I also working worked on my personal projects.

Very good!

I want to send feedback on the work of my tutor ("tutor's work" is shorter but "the work of my tutor" is also correct."

I really like using the English language to explore the world and discover new opportunities. English is the international language spoken by many people. (perfect.) I can travel to other countries and learn about other cultures. Currently I have a low level of English, but I'm trying to improve it. (lol your English is excellent) Olga is my mentor, my friend, and my critic.
Olga is a great teacher: she gives systematic training, individual approach, selects what you really need, and very often brings something new and interesting in the lessons. I am expressing gratitude to her! I plan to continue with her classes and reach with her to success.

Excellent. Very well done.
