What Internetario does

  • Software Engineering Building and maintaining production systems, end to end — TypeScript, Node.js, and Python; web and PWA front-ends; cloud on AWS and Google Cloud.
  • Software Architecture Designing systems that scale — distributed and real-time infrastructure, large-volume data, search and aggregation, cost and reliability.
  • Product Management Deciding what to build and in what order, alongside the engineering — including AI product management: translating user needs into technical specs and driving teams through the current AI stack.

  • Data at scale — indexing, search, aggregation
  • E-commerce & real-time systems
  • Blockchain / DeFi

Two-plus years shipping AI features for retail and reselling — content understanding, classification, matching, and mapping.
