June, 2008:
After six months of development we launched our Mirrors project into production!
Almost in two weeks we gained the popularity of thousands users per day!

From the start we have 5 web proxies:

May, 2008:
We designed and launched a couple of small sites (in Russian).
One for our local real estate agency Alpari
Another is done for our friends from a sports club Panterra Sport

October, 2007:
After several months of intensive work we finished and launched a real web 2.0 site.
RentSE.com allows people to offer their items for rent and search for items offered by other people.
JQuery library provides base for AJAX and complex interface tricks. Google maps shows location of lessors on the map making it easy to find items offered. With this project I achieved a new, higher level of site usability.

July, 2007:
The financial framework we base our payment and investment sites on has an important addition: we coded the overdraft feature for the user accounts. Currently it is used in the investment system of GF Corporation.
The solution is relatively complex, because the database-level integrity checks do not allow the negative values for the user accounts, and the negative balances are accounted in the application logic. The rule for the non-negative balance value provides the important security mechanism in online the multi-threading environment.
The list of anonymous web proxies ProxVox is complete now and fully functional. The customer provided the graphics design and we coded HTML, PayPal is connected as a payment gateway.

June, 2007:
We integrated a forum (bulletin board) into the investment web system we developed for GF Corporation.
The database used for the forum is different from the one used for the system. This increases security and isolation from the possible bugs of the forum code. The integration provides the fully transparent authentification for the users though.
We have also completed the first phase of the UberCard - complex and very interesting AJAX application.

April, May 2007:
We are developing the second version of the MyActivityMatch.com with AJAX-based features in the interface.
The speed and usability are going to be improved significantly.
A lot of work was done on the new features for the financial portal we develop and support for our customer.
Also we developed the small project: ProxVox.com, hope the customer will find time to complete it and make it running.

March, 2007:
We continue the work on the "Ubercard" project and introduced the beta pre-release of the system on its own domnain ubercard.net
The project has a new design of the front page as well.

January,February 2007:
The work is not very intensive - small projects, support and help customers with the ongoing projects.

December, 2006:
We have prepared an alpha-release of the AJAX application: UberCard. It is a rollodex-type of application. The goal is to allow to create, send, store and manage virtual business cards, being able to update the contact information when it changes.
The financial system we developed for GF Corporation successfully serves thousands of customers processing real-time online money transactions. There were just a couple of uncritical bug reports from the customers during half a year of work.

July, 2006:
The studio has completed the development and launched an online system for an investment company GF Corporation. The system includes an investment module, a virtual stock exchange, and a complex affiliate system.

June, 2006:
We developed an engine for a yellow pages site, it performs the fast context search among 14 mln US companies and 40 mln companies/categories combinations. The unique feature of the system is its speed: we spent several weeks, evaluated a dozen of different approaches to make the database search run enough fast to serve the web site on the single-CPU server.

April, 2006:
A new nice dating site YouWannaChat is completed and launched .
The current projects of the studio are the financial portal with HYIP and stock market modules, and the submission system of advertisement to the craigslist, which came out to be a demanded and very efficient service.

March, 2006:
The transfer of the grik.net domain came out to be a long and sad story.
The registrar subtledomains.com reacts very slowly.
Could not imagine that a registrar may declare the domains registered 2 years ago "unsupported".
Now I really appreciate the quality and speed of support of godaddy.com!

January and February, 2006:
Support of the recently completed projects by the developers is one of the important factors of the projects successful launch. We helped the customers of the all completed projects to get used to their new systems, fixed all issues and implemented the required changes.

December, 2005:
We successfully completed and launched the new metal-based payment system Paysilver (demo available on request).
The system provides reliability of the site's work and one of the highest in the net security standards for the users.

Nov, 2005:
The studio has completed the development and successfully launched the new activity matching (sports partners) service My Activity Match.

Oct, 2005:
Server-side browser: the text parsing engine for rewriting of the HTML, Javscript and CSS is completely rewritten. This was a complex, but very exciting work of finding out the ways the browsers act in the non-standard situations.

The studio has developed the internet banking web system for the Western Commercial Bank.
We expect it to go live when the customer completes their work on the text contents.

Grik.net has moved to the new server. This long and hard process took 3 weeks of preparations. The migration went smoothly, all sites and services were working without any interruption or failure.

Aug, 2005:
The submitter is launched!
Now we are submitting announcements to the craigslist.
The site we are promoting is getting 900 new real visitors during a day. The result is the visual increase of site's sales.
When we finish testing the system in production, we will offer the submission service to the customers and add other popular classifieds as well.

July, 2005:
We are working on the complex web robot, its first task will be to submit numerous announcements to the craigslist.org
The solution uses the core of the Server-side browser for HTTP connection and data processing. The rules in XML files make the system very scalable and flexible.
The blog service is launched online and is available as a part of the grik.net site in the beta version.
Several small projects gave us good feedbacks that you can see on the site.

June, 2005:
Server-side browser core is updated, latest CURL features are used. Current productivity allows us to have the server loaded just by 3-5%.

May, 2005:
The studio has closed a cooperation agreement with the software consulting company InfoParc for developing web based applications on LAMP/WAMP stack.

May, 2005:
The studio has completed several small projects, one of them is an engine for a nice site, dedicated to the pigeon races: DiVinciManger

May, 2005:
The Server-side browser" project suddenly came out to be so popular, that the server is getting overloaded. The most resource-consumptive features became available after the paid subscription.

April, 2005:
After 4 months of work the development of the complex, very secure and scalable financial portal framework is completed. The portal included:
  • the feature-rich payment system, automatically processing operations with the whole number of other popular payment systems, like PayPal, E-gold, Webmoney, and providing the convenient interface to process and account the wire transfers, checks and Western Union transfers;
  • the system for the public e-currency exchange trading floor, where anyone may place his/her quotes to exchange one e-currency to another.


December, 2004:
Developed the web-based virtual stock exchange - the financial site where people may trade virtual stocks, placing the bids for buy and sell and trading on margin, as in the real stock market. Project included the development of the financial model of the stock exchange, so here I was not just a programmer, but a financial analyst also.
