Solution Architect Key Responsibilities: Lead the architecture assessment and technical optimization of the existing in-house web application and its supporting components. Perform a comprehensive current-state architecture analysis , covering: Application and system design End-to-end data flows Database structures Integration points and interfaces Application and infrastructure dependencies Assess the existing technology landscape, including Angular, Java, Python Flask, Nginx, Microsoft SQL Server (MSSQL), Oracle LRCF , and the associated data synchronization architecture. Define the target solution architecture , including: Logical and physical architecture Component responsibilities and dependencies Interfaces and integration patterns Deployment architecture Data and integration flows Review existing architectural decisions and identify gaps, risks, technical debt, and deviations from architectural standards , providing actionable recommendations and mitigation strategies. Review and recommend improvements to authentication and authorization mechanisms , leveraging OAuth 2.0, Azure AD, IAM roles, and FUN groups . Ensure a clear separation between administrator and local-user capabilities through appropriate Role-Based Access Control (RBAC) and authorization models. Assess the automated synchronization of model-point data from the Oracle LRCF database to the QUASII database , including data flow, reliability, consistency, monitoring, and failure-handling mechanisms. Define architectural solutions to support key non-functional requirements , including: 24x7 availability and resilience Responsive application performance Scalability Maintainability and supportability Excel compatibility Secure data processing and handling Update and maintain the Solution Design Document (SDD) , ensuring it includes: Architecture views and diagrams Integration architecture NFRs and quality attributes Architecture decisions and rationale Dependencies and assumptions Identified gaps and risks Quality scenarios and acceptance criteria Collaborate closely with Product, Development, Business, Security, IAM, Infrastructure, Enterprise Architecture, and Architecture Governance stakeholders. Provide architectural guidance to development and technical teams and ensure proposed solutions align with enterprise architecture, security, and governance standards.
