cBizSoft is a Dallas, TX-based SaaS provider of Exelare — a web-based recruiting CRM/ATS covering the full hiring cycle (job requisitions, candidates, communications, documents, reporting). Technical owner of the web application: architecture, code quality, UI platform evolution, and key integrations. • Architected and led development of a large-scale Angular application (100+ feature modules), owning the technical roadmap, modular design, and migration strategy from Angular 8 through 17+ (Angular 21 migration in progress). • Engineered and evolved state management using NgRx (store/effects/selectors), decoupling business logic from components and improving maintainability across the application. • Solved critical UI performance bottlenecks on large datasets — virtual scrolling and fine-tuned change detection cut list- rendering time by ~30% on views with 10,000+ records. • Designed and integrated an AI-assisted workflow using OpenAI: defined MCP tool schemas and client-side call orchestration to automate core ATS tasks (entity search, content generation, action automation). • Use AI coding assistants (Claude, Cursor) and multi-agent workflows as part of daily development to accelerate delivery, owning the review, testing, and validation of AI-generated code before it ships. • Built a full testing and delivery pipeline — a 200+ scenario Cypress E2E suite plus Jest/Karma unit tests — wired into Azure DevOps CI/CD (YAML pipelines, releases, self-hosted Windows build agents). • Mentored a core team of 4–5 engineers through code review and architecture sessions, and ran the team's Agile/Scrum process (sprint planning, estimation, retrospectives) as the primary frontend technical authority.

Moscow-based IT / systems integration company. Worked on a UI Builder — a platform tool for assembling configuration-driven web applications (low-code / metadata-driven UI), generating interfaces dynamically from a data model and configuration rather than a single end product. • Developed the core components for a low-code UI builder, enabling dynamic generation of interfaces from metadata for 50+ distinct data models — including dynamic forms, tables, layout containers, and Angular CDK-based overlays/drag-and- drop. • Optimized rendering of complex, dynamically generated UIs by implementing granular change-detection strategies, reducing unnecessary re-renders by an estimated 25%. • Drove technical standards by leading code reviews and contributing to the Angular/library upgrade strategy, ensuring platform stability and maintainability.

IT outsourcing / systems integration company. • Developed and shipped native Android applications for external and internal clients — including a vehicle-tracking app, a courier delivery app for KFC, and an internal employee time-tracking tool — and contributed to .NET/ASP.NET backend projects and JMeter-based load testing for a government client (MGFOMS)
