Professional Summary
Senior Angular Engineer with 9+ years of experience designing, building, and maintaining
large-scale, data-driven enterprise business applications. Expert in Angular 18+,
TypeScript, RxJS, NgRx and Webpack, with a strong focus on frontend architecture, Nx
monorepos, and Domain-Driven Design (DDD). Experienced in implementing frontend
security best practices, E2E testing (Playwright; familiar with Cypress), and integrating
frontend layers with Java-based backend systems via REST APIs. Highly independent
developer with a proven ability to take full ownership of frontend architecture decisions,
collaborate with UX/UI and backend teams, and deliver production-grade systems used by
thousands of users. Practical knowledge of object-oriented programming and design
patterns, with attention to accessibility (WCAG) and design system consistency.

Angular CLI, Webpack
• Framework Adaptability: Primary focus on Angular; comfortable picking up Vue as
needed
• Languages: TypeScript, JavaScript, HTML5, CSS3, SCSS/SASS
• State Management & Reactivity: RxJS, NgRx, Redux, Reactive Programming
• UI Libraries: Angular Material, PrimeNG, Design Systems, Component
Architecture
• Backend Integration: REST API Integration
• Testing & Tooling: Cypress (E2E — familiar via Playwright background), Jasmine,
Karma, Git (GitHub / GitLab / Bitbucket), ESLint, Prettier
• Methodologies: Agile / Scrum, Domain-Driven Design (DDD), Frontend Security
Best Practices, Cross-functional Collaboration
• Engineering Practices: Object-Oriented Programming, Design Patterns, Web
Accessibility (WCAG), CI/CD
Key Engineering Expertise

• Designing scalable frontend architecture for enterprise Angular applications using Nx
and Domain-Driven Design (DDD) principles for scalable micro-frontend
ecosystems.
• Developing and maintaining complex business workflows and new frontend modules
with DDD-aligned domain boundaries, financial/educational data-driven UI, and
dynamic interfaces.
• Integrating Angular frontends with modern and legacy PHP-backend ecosystems
via optimized REST APIs.
• Ensuring high performance, responsiveness, and code quality with ESLint, Prettier,
and SonarQube, while applying frontend security best practices (XSS prevention,
CSP, secure API communication).
• Demonstrating high autonomy, self-organization, and effective communication within
distributed, cross-functional teams (including business and analytical stakeholders).
• Building interfaces aligned with UI/UX guidelines and digital accessibility standards
(WCAG), collaborating closely with UX teams and Figma to ensure design-to-code
consistency.

Professional Experience

HeRo Study — Kazakhstan / Remote

Senior Angular Developer | 15.08.2019 – 01.07.2026

• Architect and develop large-scale Angular 18+ modules for enterprise platforms,
utilizing Nx monorepos for scalable micro-frontend architecture with DDD-aligned
domain structure.
• Design, implement, and test new frontend modules with E2E testing (Playwright;
familiar with Cypress API); maintain complex business systems with dynamic
workflows, validation logic, and reactive UI — while enforcing frontend security
standards.
• Successfully integrate Angular applications with backend services, collaborating closely
with backend engineers (PHP/REST API teams) to align data structures.
• Take full ownership of frontend deliverables, ensuring code quality, high performance
for large datasets, and compliance with best practices.
• Collaborate daily with analytical, business, and development teams to translate business
requirements into scalable frontend solutions.
• Designed and implemented an AI-augmented development workflow within the project:
integrated Jira with n8n and MCP (Model Context Protocol) to automatically pull ticket
descriptions and context, enabling immediate start on tasks without manual lookup.
Connected MCP servers for design systems, Figma, and Stitch to bring design specs and
prototypes directly into the coding workflow. Authored custom Cursor rules to
standardize AI-assisted work across feature development, testing, architecture
 decisions, and code style — improving consistency and delivery speed across the team
improving consistency and delivery speed across the team, while maintaining
responsibility and quality control over AI-generated output.

Selected Technical Achievements

• Monorepo & Micro-frontend Architecture: Designed and scaled enterprise-level
frontend using Nx monorepos and DDD principles, improving build times, code
reusability, and team autonomy across modules.
• Enterprise UI Systems: Built a complex gradebook/data UI in Angular 18+ capable
of handling large datasets and hundreds of interactive, reactive cells with zero
performance lag; covered with Playwright E2E test suites.
• Backend Integration: Streamlined frontend-to-backend communication by designing
clean data normalization layers for REST APIs, working in environments with PHP
architectures.
