Architected and implemented a generic interface infrastructure foundation for FlexTPA™ benefits administration system.Worked closely with both Product Manager and CTO to present implementation strategy and estimate timelines, as well as to provide regular progress updates.Analyzed vendor requirements based on a multitude of interface specifications and established best patterns for interface implementation and testing.Implemented a number of both real-time and on-schedule data exchange interfaces between FlexTPA™ and other insurance systems.

Performed in-depth architectural analysis and identified areas requiring refactoring. Conceptualized and carried out a complete re-engineering of the Data Access Layer using NHibernate which increased feature velocity by ~30% across the teams and reduced code viscosity, while offering a vastly improved uniform pattern and advanced yet simplified data query and manipulation capabilities.Designed and orchestrated the implementation of a fully revised reservations engine that introduced a host of mission-critical enhancements.Authored, architected and laid the foundation for a unified B2B interface infrastructure featuring notification triggering, message queues, flexible value mapping, interface instrumentation and alerts, reliable messaging, payload audit and data archival, - in a multi-tenant cloud-based SaaS solution.Architected, oversaw and guided to a successful completion the implementation of a multitude of B2B integration projects with a range of industry vendors including several Central Reservation Systems, Revenue Management Systems, Access Control Systems, POS Systems, Online Booking Engines, In-room Entertainment Systems and others.Worked closely with Product Management to scope, estimate cost and prioritize user stories, identify potential issues and work out action plans. Gathered requirements and communicated directly with vendors to negotiate messaging specifications and establish proper communication patterns.Identified and allocated tasks for team members, provided continuous development, testing and deployment guidance and coordination using Lean principles. Monitored team progress during Sprints and took action to help resolve impediments and mitigate potential risks. Performed regular code reviews to establish and reinforce best coding patterns and practices, including SOLID.Worked closely with QA team throughout the development cycle and facilitated a number of interface certifications with partner vendors, with a 100% success rate.

Provided architectural leadership in a distributed Agile development team through the design, implementation, delivery and post-production phases of a series of strategic innovative projects including:sms|Diplomat - A multi-protocol B2B communication gateway with asynchronous messaging support and guaranteed delivery capabilities.sms|Commander - A state-of-the-art distributed instrumentation and monitoring solution. Started as a personal project and quickly gained popularity within the company. Enabled the Operations team to remotely monitor, anticipate and proactively resolve potential problems in production systems, while also providing automated resolution for a number of trivial scenarios.sms|GlobalGuest - A multi-directional guest data collection and replication system with CRM capabilities featuring real-time centralization and sharing of guest profiles and preferences across multiple hotels in a hotel chain, allowing to expand overall guest experience by tailoring offerings to each guest’s needs and expectations.sms|WorldXA - A guest-facing online booking system with advanced dynamic content capabilities.sms|InstallCenter - A distributed deployment system for centralized publishing, execution and monitoring of software updates, with scheduling capabilities.sms|Kiosk - A self-service application for unattended guest check-in/check-out.

Shortly after starting, identified primary underlying problems with the solution, initiated and oversaw solution modularization, which resulted in a vastly improved code clarity, proper separation of concerns and elimination of business logic duplication, coupled with a substantially increased application stability.Led the team through multiple rounds of performance tuning and SQL query optimization, which yielded up to 80% performance gain in a number of areas.Oversaw the implementation of an integration project with a Golf booking system to a successful completion.
