• As a Backend Engineer at Nykaa, I had the privilege of contributing significantly to the success of the company. I was a key member of the team responsible for managing the Checkout and Payment services, which are integral to Nykaa's diverse business units, including Beauty, Man, Fashion, Superstore, and Retail stores.
• Key Achievements:
• PCI-DSS Compliance Project: I led a critical project aimed at making Nykaa's card payments PCI-DSS compliant. This involved optimizing the existing flow to minimize in-scope code, achieving compliance within set deadlines.
• Unified Checkout Service: I successfully unified the Checkout service across all Nykaa business units, streamlining deployment models, reducing infrastructure costs, and simplifying maintenance.
• Enhanced Customer Experience: By integrating Payment Gateway callbacks for real-time payment verification, I significantly reduced customer wait times for order confirmations, contributing to improved customer satisfaction.
• Backend Control and Performance: I implemented server-to-server integrations with industry-leading payment gateways, providing the backend with more control over various processes and reducing dependencies on front-end components. This resulted in consistent performance across different devices and app versions.
• Security and Monitoring: I introduced security measures such as JWT authentication and checksum validations for data integrity. Proactive monitoring, including alerts on logs, dashboards, and database tracking, ensured prompt response to deviations in success rates.
• Mentorship and Collaboration: Beyond technical contributions, I actively mentored and assisted team members in overcoming design challenges and conducted second-level reviews to maintain code quality.
