Frontend Developer (React / Next.js / Angular)

Worked remotely on multiple outsourcing and staff-augmentation client projects, taking ownership of frontend architecture decisions including state management, SSR strategy, and reusable codebase practices. Developed React, TypeScript, and Next.js solutions for product-focused applications across AI, media, SaaS, and ecommerce domains.

Improved rendering performance through render-critical component refactoring, reduced render-blocking resources, route-based code splitting, dynamic imports, stricter chunk boundaries, TanStack Query caching, and responsive image loading. Migrated a legacy SPA to Next.js with SSR and SSG, implemented GA4 and Google Tag Manager conversion tracking, and introduced Cursor and Claude workflows for faster routine feature delivery.

Delivered end-to-end features across six production client engagements in SaaS, fintech, insurance, legal-tech AI, automotive marketplace, and ERP/CRM domains. Built React and Angular applications involving state management, payment systems, administration interfaces, AI chat, and high-volume data experiences.

Implemented and tested merchant and payment gateway checkout integrations, created a content and catalog management admin panel, and integrated an SSE-based AI chat with DOMPurify protection against XSS. Architected an Angular Universal marketplace with more than 2,000 listings and 50 filters, built a virtualized ERP/CRM table for more than 5,000 rows with Jest tests, and established GitHub Actions CI/CD pipelines across Vercel, AWS, and Nginx environments.

Completed part-time remote bachelor's studies alongside full-time frontend development work.
