At SimClaire, I build and operate the backend for a production eSIM marketplace serving customers across 150+ countries. I work on global data plans, order processing, country-based pricing, and Stripe payment workflows handling around 40 orders per day.
I've built idempotent Stripe webhook processing, BullMQ pipelines for eSIM delivery and provider fulfillment, Redis caching that reduced latency from 10–12 seconds to about one second, and JWT and rate limiting across roughly 20 REST APIs.
I've also built Node.js/Express platforms for travel bookings and custom CMS workflows, contributed scalable backend planning for farm management, and created secure Linux administration and kitchen management systems.
