such as synergy of multiple trading criteria. Developed a security layer for validating of account information,
personal information and expiration date in one popular Forex trading platform. Developed a dll which helps to
validate the expiration date of automated robots using independent date-time information requested from world
time servers. Co-developed large-scale inventory system in collaboration with software development team.
Used technical environments, computer languages: Windows (XP, Vista), C/C++, JAVA (JDK), DB2, C#,
MQL4-language, scripting language and compiler, MethaTrader and MetaStock platforms, MS .Net Visual Studio,
MS Office, scientific libraries, numeric methods
IBM / RATIONAL (2004-2009)
Staff Software Developer (2004-2008), Software Architect (2008-2009)
• Developed several major real-time features and solutions built into the Rational Portfolio Manager (RPM)
database, presently considered to be the world-wide strategic project management tool in IBM. The key features
and solutions that I developed met business requirements, demonstrated robustness and received strong positive
feedback from customers and senior management. Participated in risk assessment process and collaborated with
certain customers to develop “hot-fix” strategies.
• Played important role in determining business requirements, in defining of system requirements and
investigating solutions’ compliance in client-server Web-based multi-tier application such as RPM. Launched a
number of initiatives that helped the team to fix critical situations and escalations, e.g. took leadership in the
enhancement of RPM, developing a special mechanism for handling exceptions, significantly improving the
code diagnostics at the exit points. Recommended solutions to improve reliability and performance of database
and core middle-ware. Also, designed and implemented procedures to ensure instant detection and resolution of
data corruption in the core application during processing of the “Resource Allocation and Scheduling” function.
• Owned the business tracking of a few fundamental real-time RPM’s features including “Calculate/Leveling”,
“What-If? Scenario?”, “Import/Export”, Projects fiscal enrolling and “Time-phased budget” interfaces. A
number of core application’s functions such as tasks scheduling, critical paths, priority control in Project’s work
breakdown hierarchy, dynamic resolving of dependencies and resources allocation had been A to Z developed
by me. About ~80000 lines of developed by me code essentially contributed to the overall database code in
RPM. With the time I optimized the most of developed by me code, which in some cases enhanced
performances of scheduling/allocating functions by 8~12 times. Recommended improvements to a few other
business functions; e.g. initiated the replacement of the code of circular dependencies checker by offering a
conceptually new and robust solution. This resulted in customer satisfaction, enhancing the performance of basic
“Create Dependency” function by 30-40 times.
• Developed a few “extra” features in advance of the forthcoming releases. Despite the underlying technical
complexity, the new features such as “Circular Dependency Checking”, “Dynamic Scheduling of Tasks &
Resources”, and “Determining of scheduling conflicts between Tasks” were recognized for their functionality
and user-friendliness, which made the application more attractive and capable of competing with industry
leaders such as Microsoft Project.
• Developed a number of unique high-efficiency computer algorithms including circular dependencies checking,
heuristic scheduling algorithms, quick ordering of priority driven hierarchical networks, stable quick sorting and
binary search of indexed linked lists etc. Led R&D work in the area of project portfolio optimization. Proposed
solution is capable of competing with recently launched MS Portfolio server product. Importantly, demonstrated
that combining a technique of multi-objective quadratic programming with the synergy of project dependencies
can effectively solve the optimization problem. Played the leading role in the development a conceptually new
idea of “Project Diagnostics and Quality Assurance” and justified a development of a tool that would help
achieve break-through in the future of RPM product.
