At Nest Data Group, I own the backend of nyronX, a multi-tenant retail and pharmacy SaaS platform used commercially every day. I take its Node.js, Express, and TypeScript services from data model through production operations on PostgreSQL and AWS.
I built nyronX’s offline-first synchronisation protocol for LAN hubs and satellite registers, with idempotent writes, offline fiscal commits, and automatic reconciliation. Replacing full-table synchronisation with gzipped delta sync reduced cloud egress costs by approximately 75× per tenant.
I also integrated three national regulatory systems for fiscal receipt reporting, e-invoicing with X.509 digital-signature authentication, and pharmaceutical track-and-trace. The platform includes subscription billing across three national payment providers and a drug-data pipeline for catalogue and government-classifier records.
Previously, at IPM – Integrated Projects Management S.r.l., I led front-end development for two enterprise IoT monitoring products, shaping architecture and API contracts and establishing unit and end-to-end test coverage. I’ve also taught and supported full-stack students at Strive School, and built independent APIs and a question-and-answer platform.
