Project architecture selection, evaluating alternatives.
Number of different projects implemented in set of technologies. More details on request.
I was involved as a junior developer into number of commercial projects developed at that moment. Business area: healthcare.
Challenges: to develop robust code generation framework that will allow rapid development of high load capable websites with php4 backward compability. XSLT was used as a powerful framework for code generation. Set of procedural plain php files where generated as a result of transformation. During set of projects, generated websites were able to handle and serve 6000-7000 concurrent business user sessions (up to 8900 in extremum) in following live environment: single server with Nginx supporting PHP fast cgi mode as a web server, MySQL as a DB server, Memcache as server side cache. Server network card was configured to use polling mode.
Facts: since May, 2005 until May,2011 over 160 solutions were implemented by our team using this code generation approach. By using xml based grammar, all websites allow smooth generator version upgrade without need to change business logic code itself.
Deployments: banking sector (bank public sites, bank intranet portals), news and media (number of highload news ukraine sites), entertaiment (websites for tourists, event solutions), b2b and b2c solutions (set of sites solving business needs with custom made logic), custom ( set of custom made websites solving multiple client needs).

Business challenge: Team created a computer-based driving theory test system integrated with a 3rd party web-based test booking system. The system is touch screen based and has an intuitive user interface as well as invigilator console. System runs on 7 test stations, but is extensible. Licensed question bank was used as a initial source of theory test questions. The system features include a generation of unique tests for each candidate and the facilities for the administrative staff to add/edit questions as needed.
Benefits: Provides a standard way of conducting driving theory tests. 3rd party systems consume information (in particular driver licensing software). Minimum effort on maintenance of the testing process, easy to operate during the test - even for people with low computer literacy, automatic assessment of the test results, Immediate communication of the results to the participants. Necessary reports and statistics was implemented management staff per requirements.
Facts: System still operates. Approximate software lifetime expanded up to 2016.
Background:Region: UK, Industry: E-Goverment, Service: Corporate Application Development.
Role: Architect, project leader.
Business challenge: Team created bespoke computer system, that allows citizens to book and pay for theory and practical driving tests online. System includes separate backend with business logic and public front end part in DMZ. System is integrated with customer inner systems serving driving licence workflow, online passport system, 3rd party online payment systems, provides reports in format of inner financial systems, other reporting.
Benefits: Provides more online capabilities for citizens, decreases staff load in the office.
