At Reply, I architected a digital-asset offering service with NestJS and PostgreSQL, and owned an investment purchase flow from product review through release. I connected React interfaces to Node.js APIs and payment-provider callbacks, and built Kafka consumers that cut processing catch-up time from 18 to 6 minutes.
At msg systems Romania, I developed services and interfaces for a financial client’s payment reconciliation flow, reducing a daily run from 31 to 17 minutes. Earlier, at Sigma software, I built APIs and React components for a client’s account and billing portal, including payment-provider callbacks that reduced manual status corrections from 14 to 5 per week.
