Arthur Rybalsky

Provided architectural leadership and developed architectural artifacts for major initiatives across multiple Lines of Business. Notable initiatives: AI Sales Call Analytics • Translated the business proposal into AI analytics platform with comprehensive sales call assessment • Run a proof of concept demonstrating that business objectives could be met under strict budget constraints. Utilized NLP, LLMs, speech-to-text, and speaker diarization • Defined and validated AI analytics outcomes, designed a multi-level scoring model to quantify AI analytics results • Architected the end-to-end solution, including system design, domain and data models, integration with the company’s flagship product. Focused on Secure, Resilient, Cost-Optimized and High-Performance Architecture • Directed three cross-functional engineering managers across design and implementation, driving resource allocation, hiring, provided high-level cost estimates Gamification project • Designed an architecture integrating external data feeds through an ETL pipeline, with an API Gateway for security and flow orchestration, and integrated it with new Gamification and Scoring modules, legacy systems, and enterprise Identity & Access Management • Designed core Gamification and Scoring multi-tenant data models, process flows with user engagements such as Points, Streaks, Budges, Promos, Leaderboards, personal challenges, overlapping draws, user scores, etc • Provided high-level design and template implementation for new Gamification and Scoring modules • Managed four cross-domain engineering managers during implementation CapOptix - Sales guidance system • Participated in product definition sessions for MVP and final solution, identified product improvement and deviations from product philosophy, led requirements gathering and analysis • Created architecture documents including Use Cases, Logical, Physical, and Deployment diagrams, and developed solution for resilience, high availability, and failover

• Played key role in digital transformation roadmap building, aimed to digitize marketing, CRM and sales processes with individuals performance tracking, leads analytic tracking, process decision points, facilitates and guides dialog with customers • Develop Enterprise Architecture vision, roadmaps, principles, models and ensure its implementation and continuous improvement • Created detailed analysis of the current assets, current state architecture and how those components can be reused in target state architecture • Assessed customer requirements, performed gap analysis and translated into logical architecture designs for consumption by the design and development teams • Presented technical architecture to executives, clients, architecture review board, operations and other stakeholders • Defined and published Architectural diagrams: Business and System Context, Conceptual, Logical, Physical and Security Views • Provided assessment of the feasibility of moving from the “as is” to future state architecture by identifying and evaluating impact on the organization and associated risks, benefits and costs. Recommended courses of action to reduce and mitigate risks • Worked closely with technical delivery teams to ensure the project implementation aligns with the enterprise architecture and standards

Responsible for architecture and design, over-see the development, integrations, and deployment, ensured that solutions adhere to corporate and industry standards Project DSIL. Created highly scalable end-to-end solution architecture to integrate external Bell IVR system with CIBC back-end legacy systems

Led the architecture and design of the Lottery Gaming Gateway • Performed Service Specification activities, defining service contracts, service interfaces, message schema/ Canonical Data Model, functional behaviour and Quality of Service (performance, availability, scalability, manageability and changeability), as well as creating deployable WSDLs and XSDs (XML Schema) • Lead proof-of-concept (POC) on low-latency data replication between two datacenter, implemented in-memory data grid, performed stress tests and documented test results Designed template implementation of message flow processing. The flow consumed Web-Service SOAP call from iGaming system, performed request validation on JEE Server, saved state in distributed memory, and performed call to OLG legacy system • Lead design to enhance server security on B2B model with Domain name validation and two-ways SSL/TLS 1.2

Designed end-to-end solution architecture to integrate Panorama - pan-Canadian public health surveillance system with IFIS financial and NOVA inventory Jurisdictional systems • Created Conceptual, Logical and Physical data models, System architecture, SOA Service Specification, Deployment models architecture artifacts required by Zachman framework • Designed application message processes workflow. The flow performed pull data Web-Service call to Panorama through SOAP request, land data in application Oracle DB, transferred data to remote integration server through REST WS call, transformed data to appropriate format and generated SFTP calls to integrated platforms • Created Web UI architecture and design for manual problem resolutions and system configurations • Designed distributed data integrity validation and escalation framework for long-lived transactions to ensure all entities were processed by integrated systems, and their states are synchronized back to the source system • Reviewed performance test plans and test results to ensure compliance on SLAs, helped developers to enhance PL/SQL procedures to improve query performance

Modernization initiative to port legacy systems to Java EE umbrella • Analyzed current state technology environment and developed future state architecture, led an effort to create transformation program road map • Developed solution architecture to support Core Business Processes • Created Enterprise integration approach for SSO, user authentication, authorization and provisioning • Created Conceptual, Logical and Physical architectures for ASR (Admin System Replacement) • Overviewed design of Work Flows and BPM under Pega Rule Process Commander (PRPC), designed User Interfaces (section, harness, flow action), portal representation, created validations (property-validation. obj-validation) rules • Designed compensation transaction workflow to integrate with non-transactional legacy systems. The workflow used Transactional Steps pattern to provide failover capability for long-lived transactions

Provided architectural support for two distributed platforms: in house developed Bureau Interface Server (BIS) and EDGE packaged solution. Lead two development teams • Participated in requirements gathering meetings with both the business and technical teams  • Estimated and planned projects and works, and reported on risks and issues throughout Identified architecturally significant requirements to define the most appropriate system solution and provided high level sizing • Proposed, documented, and presented the architectural views of the system solution from conceptual to deployment – J2EE, SOA, and application integrations • Proposed and applied industry architecture styles, principles, processes and best practices – distributed N-tier, component-based, service-oriented, workflow-driven, model-driven development, service taxonomy, SOA principles & patterns, TOGAF • Coordinate the technical activities among internal technology groups and vendors, according to the formal engagement or RFS processes • Ensure compliance to enterprise technology standards and lead the journey of technology governance processes
