Dear Client
I just read your job posting word by word carefully.
Although I am a newbie on upwork, I am a programming expert with full experience in mobile and web projects.
I have more than 8 years of programming experience, especially the recent 3 years I served as a top developer in Zapporoo, an app design company.
I've published 30+ mobile apps and websites, got great reviews from a lot of clients, and a valuable experience in mobile and web marketing. (I can provide links of previous projects if you want.)
In your job posting, you want to fix some bugs in your source code.
It is not problem for me.
I will guarantee you good credit and high quality about my work.
And I can adjust my working time as your timezone, work 10+ hours per day.
I am looking forward to hear from you soon positively.
Thanks you for reading!
Best Regards.
