Architected and engineered an end-to-end B2B SaaS platform for managing physical asset inspections, employee safety certifications, and automated compliance reminders. The system streamlines compliance and maintenance tracking, unifying them under a tiered SaaS architecture.
Managing physical asset inspections, fleet tracking, and employee safety certifications required a centralized, automated system. Previous industry methods relied on scattered spreadsheets and manual follow-ups, leading to costly delays, missed renewals, and compliance violations.
Engineered a centralized B2B SaaS platform utilizing a robust Node.js/Bun backend. Integrated automated cron jobs and RabbitMQ queues to seamlessly dispatch Twilio SMS and AWS SES email reminders, alongside a feature-gated Stripe billing system.
Delivered a production-ready compliance engine that eliminated missed inspections. The system successfully gates features across multiple subscription tiers and provides offline-ready PDF reports for field audits and regulatory compliance.

Integrating RabbitMQ with Twilio and AWS SES enabled reliable, asynchronous delivery of critical compliance reminders without blocking core API threads.
Decoupled the notification engine using RabbitMQ to ensure timely dispatch of SMS and email alerts, even during traffic spikes or third-party API rate limits.
Implementing Stripe webhooks for subscription lifecycles required careful architectural planning to handle transient network errors.
Built idempotent webhook handlers to guarantee that subscription upgrades, downgrades, and cancellations were processed exactly once, preventing duplicate billing states.
Generating comprehensive compliance reports on the fly required optimizing server memory allocation.
Offloading PDFKit report generation to asynchronous background workers prevented the main thread from blocking during large multi-page compliance exports.
