Business or sector: Customer Engagement & Rewards Platform

Project: High-Load Multi-Brand Loyalty Platform

About the project

A multi-brand, high-performance web platform serving millions of users with personalized dashboards featuring tiered levels, bonus balances and VIP statuses. Fraud prevention and payment processing workflows were extracted into standalone micro-frontend (built with React, Nx and micro-observables) and deployed across all brands. This architecture enabled independent releases, brand-specific theming and robust real-time fraud detection in a high-throughput environment.

Responsibilities and achievements

Analytics Implementation & Monitoring

• Implemented and instrumented event and conversion tracking using Facebook, TikTok, and Bloomreach pixels.
• Configured Vercel Metrics to monitor production performance and surface runtime errors.

Zendesk Live Chat Integration

• Integrated and configured Zendesk Live Chat for multiple brands, tailoring chat widgets and workflows to each brand’s requirements.
• Extended integration with Zendesk tags and departments, dynamically routing conversations based on user attributes and business logic.
• Implemented JWT-based authentication and session management: developed TypeScript utilities to securely store, refresh, and retrieve tokens in sessionStorage, and injected signed JWTs into Next.js API routes to authenticate live chat sessions.

React, Redux & Next.js Experience

• Built scalable, component-driven UIs with React Hooks (incl. custom hooks), organized via feature folders.
• Managed state using Redux Toolkit (typed slices, actions, reducers), handled async flows with thunks and improving performance by memoizing selectors with createSelector.
• Developed SSR, SSG and ISR pages in Next.js; created custom API routes (for ex: JWT auth), analytics ingestion and live-chat initialization.
• Tuned performance through Next.js Image optimization, code-splitting, HTTP caching and Incremental Static Regeneration.

React/Nx Micro-Frontend Architecture

• Contributed to migrating fraud-related features (KYC flows, OTP verification) into isolated micro-frontend architecture using React and Nx
• Utilized a pub/sub event system to trigger brand-specific features across micro-frontends
• Extracted and maintained shared UI components and utilities as standalone Nx libraries for reuse across all micro-frontends
• Implemented centralized authentication and JWT session management across micro-frontends
• Optimized bundle sizes through lazy loading, code splitting, and deduplication of common dependencies

Code Review, Mentorship & Standardization

• Conducted technical interviews and evaluated candidates for Mid- and Senior-level frontend roles.
• Championed adoption of Clean Code practices, SOLID principles, and design patterns across team projects.
