Xnoll is a comprehensive SaaS business suite I built from the ground up. At its core is a central authentication portal (like Zoho Accounts) that handles SSO across all sub-applications, multi-tenant company management, role-based access control, subscription billing via Razorpay and PayU, WhatsApp Business API integration, support ticketing, and a full marketing website. Connected via SSO is the Xnoll Booking app — a complete online booking management system for service-based businesses with customer management, service catalogs, appointment scheduling with calendar views, time-slot management, expense tracking, GST-compliant invoicing, and rich analytics. The entire platform follows a true SaaS architecture with tenant-isolated data, centralized auth, and seamless app switching.

Key Features

• Central SSO authentication portal with Laravel Passport OAuth2 across all sub-apps
• Multi-tenant company management with create, switch, and member invitations
• Role-based access control (RBAC) with custom roles, permissions, and role assignments per company
• Subscription & billing engine with Razorpay and PayU payment gateways
• Recurring subscription plans, addons, credit packs, and usage-based metering
• Credit wallet system with auto-recharge and expiring credit management
• Entitlement system for app/module access control based on subscription
• Automated invoice generation with PDF download and email delivery
• WhatsApp Business API integration — connect Meta WABA, send template messages, track delivery
• Support ticketing system with priorities, categories, internal notes, and satisfaction tracking
• Invoice template engine with custom layouts (standard, minimal, retail, GST, service)
• Desktop app license key generation and version management
• Marketing website with product pages, pricing, solutions, documentation, and SEO sitemap
• Multi-language support (English, Hindi, Gujarati)
• Admin panel for users, billing, apps, plans, support, and WhatsApp integration logs
• Online booking system with customer management and service/service catalog management
• Appointment scheduling with day/week/month calendar views and time-slot (slab) management
• Booking status workflow with cancel and invoice generation from bookings
• Tax management with GST support and one-click import of Indian tax structure
• Expense management with categorized expense tracking and reporting
• GST-compliant sales invoicing with print, download, and customizable print templates
• Comprehensive reports — booking register, payment register, daily collection, outstanding balance, expense register, GST summary
• Dashboard with booking trends, status distribution, recent bookings, and top customers
• Custom fields per module (customers, services, bookings) for flexible data capture
• Audit logging for all user activities with archive and export
• Company-level settings with template selection and configuration

Complex Features

• Centralized SSO architecture: A single auth server (xnoll.com) handles all authentication via Laravel Passport OAuth2. Sub-apps (booking, ERP, invoice) authenticate through the same SSO flow. Users log in once and can switch between apps seamlessly. Session tokens, bearer tokens, and app-session tokens are all supported with proper middleware resolution.
• Multi-tenant company switching: Users can belong to multiple companies. The system stores a current_company_id in session and all sub-apps scope queries by this ID. Switching companies or switching to personal context updates the session and refreshes permissions across all apps.
• RBAC with permission implications: Custom roles with granular permissions (view/create/edit/delete per module). Permission implications are built in — e.g., "company.update" automatically implies "company.view". Cached permission lookups with version-based cache busting for performance.
• Subscription billing engine: Supports recurring plans (monthly/yearly), one-time addons, and credit packs. Integrates with Razorpay for subscription creation, payment verification, webhook handling, and auto-renewals. PayU handles alternative payment flows. Full lifecycle tracking with plan change history and prorated billing.
• Credit wallet & usage metering: Polymorphic wallets per user/company with per-meter keys. Credits can be purchased, consumed, granted, or refunded with idempotent transactions. Usage meters track consumption with configurable aggregation and reset modes. Auto-recharge when balance drops below threshold.
• WhatsApp Business API integration: Full Meta Cloud API integration — OAuth connect flow, WABA account management, message template CRUD with versioning, template syncing with Meta, message sending with idempotency, delivery tracking via webhooks, and wallet-based pricing deduction per message.
• Dynamic invoice template engine: Schema-based rendering with configurable sections (header, from, to, items, totals, payment, footer) and customizable column display. Multiple layouts for different use cases (standard, minimal, retail, GST, service). Template versioning with draft/publish workflow.
• Booking calendar engine: Full day/week/month calendar views showing all appointments. Time-slot (slab) management for defining available booking windows. Real-time slot availability calculation. Drag-and-drop friendly structure for managing bookings visually.
• GST-compliant invoicing: Indian GST tax structure with CGST/SGST/IGST support. One-click import of complete Indian tax rates. Invoice auto-numbering, print templates, PDF generation, and tax reports (GST summary, invoice tax register).
• App launcher with session proxying: When a user clicks "Open" on an app in the central portal, a secure session token is generated and verified. The sub-app validates the token, establishes its own session, and redirects the user — all without exposing credentials between services.

ITracxTMS is an enterprise transportation management platform used by 250+ carriers across Canada and the USA. As Senior PHP Developer I led backend architecture and built mission-critical features — from a drag-and-drop scheduler to payment integration and robust audit logging. I designed scalable, fault-tolerant systems for report scheduling and large data exports using Laravel Scheduler, Queues and job batching to ensure reliable deliveries and great user experience.

Key Features

• Drag & drop scheduling interface for planners
• Stripe payment gateway integration
• Custom audit logging system for compliance
• Subcontractor load assignment and management
• Report Scheduler with flexible recurrence (daily / weekly / monthly / yearly)
• Background CSV export pipeline with job batching and email delivery

Complex Features

• Report scheduler (end-to-end): User opens any report, applies filters and clicks "Schedule". A popup captures name, recurrence (specific date / every week / month / year) and time. These schedules are stored in DB and evaluated by a daily command. The command checks scheduled reports, triggers generation jobs at the right time and delivers the report to the user by email.
• Large CSV export pipeline: For instant small exports we keep synchronous CSV downloads. For large datasets I implemented an async export flow — on clicking "Download CSV" the request is persisted, user sees a popup informing them they will receive an email, and the system queues a job. Exports are processed in batches (chunking) to avoid memory/timeouts, with retries and failure handling. When all batches complete, an email is sent with a secure expiring link for download.
• Scalability & reliability: Used Laravel Queues, cron-scheduled commands, and job batching to make long-running tasks reliable. Implemented logging, retry/backoff policies and monitoring-friendly events so operations and support teams can track progress and failures.

This platform uses Lumen for high-performance API development and Laravel for a feature-rich admin panel. MongoDB was used for flexible and fast document-based data handling. As the backend lead of a 5-member team (2 frontend developers and 2 QA engineers), I designed the entire system architecture, developed Lumen REST APIs consumed by the Vue.js frontend, integrated MongoDB using the Jenssegers package, and built the Laravel admin panel with Bootstrap. I also developed the custom role and permission engine used across the system.

Key Features

• High-performance API backend developed in Lumen

The website combines server-rendered Blade pages for SEO-friendly public content with a React 19 SPA dashboard for the authenticated user experience. I built the complete Laravel backend with RESTful APIs, real-time messaging via Pusher, role-based access for transporters, companies, and admins, document verification workflows, and a comprehensive admin panel for managing all platform operations.
