1. Cover letter example for Experienced PHP developers

Web, Mobile & Software Dev • Web Development
Hello

I am TyaJin from Thailand (UTC+8).

Please see my comments based on your requirements:
-----------------------------------------------------------------
1) Object model:
- I used UML to develop two similar projects, which exchange XML packages to speed up video broadcasting.

2) Local storage:
- I worked with eAccelerator and familiar with APC. When I was a student, I implemented my own local super-fast simple DB on Java for the University site. 

3) Conflicts resolving:
- I fully understand the requirement. I know how to resolve such collisions on desktop applications, but need more info to figure out how it should work on PHP

4) Simultaneously processing:
- Your solution with EXE files is very interesting, but I have idea how it can be dramatically improved by using system messages technology.

I read and have some questions about your attaches, I would glad to ask them and share my ideas.

Short introduction:
-----------------------
I am very interested in this project because I like PHP coding and working with algorithms, but I am not a database architect/designer.

My profile includes some examples, but not much, because last serious works were done under NDA (it was almost 8 projects).

I worked as system architect in last two projects where I was responsible to design an object model for a development of team.

I do PHP programming more than 5years and within this period I had been working as slave coder, senior developer, team leader and system architect. So, I know all aspect of project development and have great communication skills.

I have experience with the following similar image processing libraries: Google API, GD (great experience), Imagine, Php Graphics Work (less known)

Of course, this work will require strong experience in writing unit test. I would recommend PHPUnit.

If this project will be developed by a team I may suggest to use the following very useful task management systems: Trello, Fogbugz (not free), Bugzilla and Jira.

I worked with all most popular repository systems like: SVN, CVS, BitBucket and GitHub.

My rate:
-----------
My rating is 30$, but I am ready to loosen it, because there is only feedback in my profile. Getting feedback is more important for me rather than money. Let start 22$/hr.

Some tasks may require additional research, which will not be included into payment time.

I am ready to do test job if you wish.

I can share the project progress as often as you wish.

Best regards, TyaJin

4. Cover letter example for MySQL Database Optimization Needed

IT & Networking • Database Administration
Hello

Let me help you with this task. I designed, optimized and support databases for such projects like: mailcast system - more than 10mln recipients/100mln sent emails, custom developed stats for more than 500 projects - processes 100000 pages every day.

I know much about optimization. Before doing any optimization need to decide, where is a problem. Performance issues can be:
  - on database side, on database + server/client side (so I can help here);
  - on server, client and network side (I cannot help here) 

If problem related to database then my steps are:
- gather stats when site operates in regular mode. It means that users open the same pages as they usually do. Maybe make sense to write some automated scripts (by JMeter, for example) to emulate user behavior;
- analyze queries;
- possible solutions: 
1) simple one - create missing indexes; 
2) rewrite queries; 
3) move logic into stored procedures; 
4) create indexed views; 
5) work together with a development team if the issue is partially related to the server side - for example, developer runs one query many times; 
6) separate table on static and dynamic data -  static/history data can be processed automatically by schedule; 
7) use shards - complicated part, but also possible.
8) other - can be provide after detailed analyses

My name is Isabel.

I did jobs where other specialist gave up. 

My rate is $25/hr and I can spent 10h/week. 

I need more details about your site to estimate approximate timelines/time. The details I need: programming language, DB version, hosting and the problem description.

Looking forward to hearing from you.

Best wishes, Isabel 

5. Cover letter example for Basic Database Setup

IT & Networking • Database Administration
Hello sir

I read your requirements; unfortunately, there is no yet fully functional/free and easy online DB.

I  can suggest the following options:
1) use MS Access as DB and create simple forms which allow you add/modify and filter data without knowing SQL queries

2) use MS Excel as DB and create simple forms which allow you add/modify and filter data without/with direct modifying excel sheets. These excel files can be automatically synchronized with GoogleDrive and you can access your data via the Internet - but you cannot do the back synchronization if data is modified via GoogleDrive

3) use Google Excel - this is just excel sheet in the Internet, it is useful if you phone DB is small

4) find any simple and free desktop app to manage your contacts and calls. There are tons of such app

5) search something similar for mobile devices - hope they are, but need to investigate.

Of course, I can work with TeamViewer, RemoteAdmin, RemoteDesktop and other solution to access remote PCs.

My rate is $12/hr. I think such work may take from 2h till 16h (if need to develop forms in MS Access/Excel). 

I am very polite, always answer the questions and can work in your timezone if we need do discuss the tasks.

I would glad if I can help you.

Regards, Maiden

Dear, sir

As I understood the job includes:
- get data from a web site/pages. Can you please give me URL of this site/page? Does this page/site require authorization? 
- run this script periodically to get updated data every N minutes. It can be run from local PC using Windows scheduler or from remote server by cron, for example;
- parse these pages and save results into local DB. Do you have any preferences about DB: MySql, Access, MS SQL, other?
- write queries/reports to display some consolidated stats/results. Do you have preferences: just a list of results or report, which will be nice printed?

The solution depends on your answers, but anyway, whatever you choose I can do it.  

I have great experience to parse, analyze, save, process and report data using PHP, C# + any DB.

My rate is $20/hr and I can start this job immediately as you hire me.
