Comprehensive SaaS platform for SEO monitoring, keyword tracking, and websitechange detection with multi-domain and enterprise support.
Architecture & System Design
• Architected large-scale Next.js 14 application using advanced App Routerpatterns:
• Parallel routes for modal systems• Route groups for auth boundaries• Nested dynamic segments for multi-domain handling
• Designed scalable data layer using TanStack Query (15+ query domains) withcentralized caching strategy and optimistic updates.Product & Business Impact
• Built advanced SEO monitoring engine:
• Visual diff reports (HTML, text, screenshots)
• Crawl history tracking• Custom severity-based notification filters
• Created competitor analysis system with side-by-side SEO comparison dashboards.
• Built full subscription flow using Stripe:
• Plan upgrades/ downgrades
• Credit system• Invoice history
• Payment management
• Implemented role-based access control with domain-level visibility permissionsfor enterprise clients.
• Designed onboarding and activation flow improving early user retention (guidedsetup, tutorials, Calendly integration).Engineering Excellence
• Built reusable UI kit (~130 components) including:
• Virtualized data tables
• Interactive charts
• Motion-driven UI interactions• Responsive mobile-first layouts
• Integrated Google OAuth, Slack notifications, FullStory analytics, and webhookintegrations.

Leadership & Architecture
• Architected and implemented the core shared library @atlas/core — event-driven platform core with centralized Event Bus and singleton manager pattern, used across desktop and mobile applications.
• Designed multi-instance betslip architecture using namespaced Bus events(betslip:main, betslip:quick, betslip:edit) enabling concurrent isolated bettingcontexts.
• Led greenfield rewrite initiative (“yellow-project”) migrating legacy Webpack stack to Vite 6 with strict TypeScript and Redux Toolkit.
• Defined frontend architectural standards and modularization strategy acrossmultiple product domains.
• Mentored developers and conducted systematic code reviews to ensure high engineering quality.Engineering Impact
• Built real-time betting engine with WebSocket streaming:
• Live odds updates
• Betslip state synchronization
• Bet validation, placement, cashout
• Topic-based pub/ sub subscription model• Implemented complex sportsbook business logic:
• Multi-format odds calculation (Decimal, Fractional, American, Hong Kong,Indonesian, Malay)
• System bet combinatorics using precomputed Pascal’s triangle lookup• Developed dynamic JSON-driven form engine (@atlas/ react-forms) allowingoperators to configure registration, deposit, and KYC flows without frontendreleases.
• Built and maintained design system (@atlas/ ui) with Storybook documentationand shared component library in strict TypeScript.
• Implemented SCSS-based white-label theming system with per-partner featureflags, PWA configs, branding tokens, and deployment-ready skins.
• Led full TypeScript migration, introducing typed DTOs, generics, strict contractsacross API layer.
• Established CI/ CD pipelines with Jest coverage reporting and enforced linting/formatting standards across the organization.

Developed a Single Page Application (SPA) for car sharing with Domain-DrivenDesign (DDD) architecture. It is a platform where users can reserve cars for bothlong and short periods. Additionally, an admin interface was created, allowingadministrators to generate reports, manage, and add new cars for users.
