“Automate complex pricing updates and data migrations without disrupting the existing customer base or revenue flow.”
Managed the engineering lifecycle for the Subscription platform, utilizing event-driven microservices to integrate Node.js with Chargebee. Led system migrations and pricing updates for a 100k+ customer base, driving a 20% growth in sales.
“Integrated a logic-based cancellation flow using Chargebee's retention suite, successfully deflecting 44% of potential churn and securing recurring revenue”
High revenue loss due to a lack of automated, personalized interventions during the customer cancellation process.
“Developed a Chargebee-based promo service that empowered marketing teams to launch independent subscription campaigns, significantly accelerating time-to-market for new promotions.”
Marketing agility was hindered by a dependency on engineering for every promotional launch, creating bottlenecks and delaying campaign timelines.
“Deployed a "Silent Network Authentication" (SNA) and Twilio 2FA framework for the Club Pret ecosystem. This implementation effectively mitigated widespread subscription fraud while maintaining a seamless, high-conversion login experience.”
Balancing the need for a robust defense against account takeovers and subscription fraud without introducing excessive "friction" (annoying steps) that could lead to user drop-off.
My stack is ever-evolving. I focus on the primitives of engineering: clean code, reliable testing, and high-quality user empathy.
I am currently accepting new challenges and creative collaborations. The first step of every great collaboration is a simple dialogue.
