Bellabox is a subscription-based beauty box service that delivers curated cosmetic samples from local and international brands to users monthly. The platform allows customers to discover new beauty products before committing to full-size purchases. The business model enhances brand exposure for partnered beauty companies while offering users a convenient and cost-effective way to explore skincare, haircare, and cosmetics.

The platform streamlines the subscription management process, ensuring seamless user sign-ups, automated billing, order fulfillment, and personalized recommendations based on user preferences. With a focus on customer retention and engagement, the system incorporates loyalty rewards, referral programs, and promotional discounts to boost recurring sales.

Commute is a ride-sharing platform designed for short, recurring trips like daily commutes. It features automated fare calculation, in-app wallets, real-time tracking, and integrated driver/passenger workflows — all managed through a robust admin panel and backed by scalable APIs and third-party integrations.

The primary objective of this project is to design and implement an event-driven backend system that automates the generation, validation, and delivery of healthcare-related EDI (Electronic Data Interchange) files, such as 834 (Eligibility and Enrollment), 837 (Claims), and 835 (Remittance Advice). These files are essential for secure, standardized, and compliant data exchange between healthcare providers, payers, and regulatory partners.

This system aims to:

• Ensure compliance with HIPAA and EDI X12 standards through rigorous validation (via Cotiviti).
• Enable seamless integration with external vendors like Avesis, Nations Benefits, and Reveleer through SFTP-based delivery mechanisms.
• Maintain operational transparency and traceability using real-time monitoring and logging via SigNoz.
• Support future scalability and workflow orchestration through modular design and integration with AWS services like SQS and Step Functions.
