You will get expert fixes, maintenance, or new features for your Angular application
Project details
Improve your existing Angular application without an unnecessary rewrite. I will diagnose and fix a reproducible bug, implement a defined feature, or extend an existing frontend and Node.js API while following your current architecture and coding conventions.
Choose Starter for one focused Angular bug, Standard for one small feature or up to three related fixes, or Advanced for one medium feature across up to three existing pages and an existing API.
The work can include components, forms, routing, state, services, responsive behavior, API integration, validation, permissions, and focused tests. You receive source changes, testing notes, and a concise technical handoff.
The application must have an accessible repository and working setup instructions. Complete rewrites, major Angular migrations, undefined issues, new backend architecture, infrastructure recovery, and unrelated defects are outside the fixed package scope.

About Valerii
Senior Angular & Full-Stack Developer | Vue, React, Node.js, WordPress
Bucharest, Romania - 11:11 am local time
With 9+ years of commercial software engineering experience, I can support the complete delivery process: planning the application structure, building the frontend, developing APIs and database workflows, integrating third-party services, testing critical behavior, and deploying the finished product.
Angular is my primary specialization. I earned the Certified Senior Angular Developer credential in April 2025 and completed specialized Angular Signals training. My experience includes Angular 9+, TypeScript, Angular Material, RxJS, Signals, reactive forms, reusable component architecture, state management, API integration, testing, debugging, modernization, and performance optimization.
I also develop frontend applications with Vue 3 and React. I focus on clear component boundaries, predictable state, accessible responsive interfaces, reliable data fetching, and code that other developers can understand and extend.
Frontend and Full-Stack Development
- Angular, Vue 3, React, TypeScript, JavaScript, HTML, and CSS
- Responsive dashboards, admin panels, portals, and SaaS interfaces
- Authentication, user roles, permissions, forms, tables, filters, and CRUD workflows
- Node.js and Express.js REST APIs
- PostgreSQL, MongoDB, Drizzle ORM, and structured data modeling
- WebSocket and real-time application features
- Unit and integration testing, debugging, code review, and documentation
- AWS and DigitalOcean deployment, Docker, Nginx, HTTPS, and CI/CD
Websites, WordPress, and eCommerce
I create responsive business websites, landing pages, WordPress sites, and WooCommerce stores with a focus on usability, conversion, performance, and maintainable content management.
My website and eCommerce services include:
- Custom page layouts and responsive implementation
- WordPress setup, customization, and content structure
- WooCommerce products, categories, cart, checkout, and customer workflows
- Contact forms, lead generation, analytics, booking tools, and technical SEO foundations
- Payment gateways, Stripe Checkout, subscriptions, customer portals, and webhooks
- Third-party APIs, shipping, marketing, and business-service integrations
- Domain, hosting, HTTPS, deployment, maintenance, and performance improvements
WebRTC and Real-Time Communication
I develop browser-based real-time communication features using WebRTC, WebSocket, and Node.js. This includes one-to-one audio and video calls, small-group rooms, signaling, media-device controls, screen sharing, STUN/TURN configuration, Coturn, and integration with existing SFU or managed WebRTC platforms.
My broader video experience includes low-latency streaming and production workflows using WebRTC, SRT, RTMP, HLS, H.264, and cloud-based media systems. This helps me diagnose connectivity, browser compatibility, media, and infrastructure issues beyond the UI layer.
How I Can Help
- Build a new Angular, Vue, or React application
- Create a full-stack SaaS MVP with authentication and dashboards
- Extend, debug, modernize, or maintain an existing frontend
- Develop Node.js APIs and database-backed business workflows
- Create or improve a WordPress or WooCommerce website
- Integrate Stripe payments, subscriptions, and billing webhooks
- Add WebRTC calling or other real-time functionality
- Deploy applications to client-provided cloud environments
I work best with clients who value clear scope, direct communication, and production-focused engineering. If you have an idea, an existing application that needs improvement, or a specific integration challenge, I can turn it into a practical implementation plan and a reliable release.
Steps for completing your project
After purchasing the project, send requirements so Valerii can start the project.
Delivery time starts when Valerii receives requirements from you.
Valerii works on your project following the steps below.
Revisions may occur after the delivery date.
Reproduce and review the affected code
I set up the provided application, reproduce the reported behavior, and review the affected components, services, dependencies, tests, and related application flow.
Confirm root cause and implementation scope
I identify the root cause or required extension, confirm that it fits the selected package, and outline the focused implementation and testing approach.
