• Architect and developer. Redesigned central configuration, caching infrastructure and deployment update flow.
• Designed build flow to enable "always ready for release" develop branch while still allowing commits to appear in QA and be rolled back automatically based on ticketing system.
• Rebuilt the command-and-control system for the entire application which enabled weekly deployment of a monolith application and slow feature exposure using custom hierarchy of contexts.
• Analyzed performance bottlenecks and implemented synchronized cross-node in-memory cache that reduced latency of metadata operations by 37% (as measured by NR).
• Designed WAL system to workaround shortcomings of SQLite, improving "small file upload" by 800%.The most important thing I learned: Some projects require a single dedicated person. Others need a whole team.

• Chief architect, leading 8 architects and experts at various positions, for an IT service management product offered “as a service” handling millions of user generated records in a self-enrolled, multi-tenant.
• Designed a completely new product, from inception to deployment and upgrades.
• Designed the fundamental conceptual (logical) data model for the problem domain. The data model is stable, compared to previous attempts that didn’t maintain compatibility over time.
• Designed an event-based workflow system that reacts to data changes and applies customizable business logic. We achieved significantly higher concurrency (100’s of changes per second) by processing bulks in memory and.
• Designed an expression evaluation language using formal grammar that let customers define binding between actions and data items. Because of its declarative nature, we manage to detect possible issues before evaluation.
• Designed a high capacity SLA tracking system. The new system takes advantage of aggressive denormalization and parallel computation to track millions of on-going SLAs with relatively small impact on foreground jobs.

• System architect for a CMDB system that discovers and holds network topology, software services and logical services. The system is built as a graph database using relational database for storage.
• Designed and led implementation of a single internal configuration storage, unifying over 4 such services in the system. The new mechanism allowed inter-dependencies to be discovered and validated, maintained snapshot.
• Designed a high availability solution based on over-the-network server cache updates using peer-to-peer communication. The solution improved read performance for a 2 server cluster by 80% and reduce time to recover.
• Envisioned and designed a new light-weight UI based on GWT.The most important thing I learned: Not to be afraid of large changes, but rather make them gradually. Even a two- year plan can be done - but it takes two.

• Member of the topology team, responsible for graph based queries and other computational data processing.
• Rewrote a large sub system from scratch, eliminating a significant cache (100’s of MBs) on the server and still managed to improve performance by more than 10x.
• Wrote a significant part of the product SDK while maintaining a "design for future compatibility" attitude. Compared to the previous “APIs are private” behavior, the SDK kept it’s basic compatibility and semantics for.
• Lead the upgrade system effort and wrote a system that analyzes user changes, and re-applies them over new out-of-the-box content, similar to version management systems. Compared to previous upgrades, the new system.

• Responsible for a swing applet as the front end of the product. Awarded “MVP” of the group at 2007.
• Overhauled client side memory issues. Increased stability to 100’s hours of constant operation.
• Overhauled client startup flow. Reduced startup time by 50%.
• Developed caching system to eliminate redundant server calls. Eliminated redundant "fetch data" requests based on cache. Improved performance by 900% for main flows.

Delphi developer: UI, Database model and interaction with Microsoft Word and other 3rd party software.Responsible for the product.

A summer job during my school days.(Continued from a year before) Developed and maintained a system for cataloging documents allowing web-based retrieval (Visual Basic 6)
