    Voice ordering and stale menus

    Velozient / HungerRush · Remote contract

    I am contracting at Velozient now, embedded with HungerRush on OrderAI, a voice ordering system for restaurants. I work on the .NET side of LLM calls, Twilio ConversationRelay, menu snapshots, Teams alerts, and the parts where a retry should not send the same order to the POS twice. It is still restaurant software: the customer wants food, the system wants edge cases.

    Remote backend contract work

    BairesDev · Remote

    I did remote contract work for a few US products. There was fleet telematics with 150M+ daily vehicle signals, Shopify sync against a 100K+ item catalog, Lambda image processing, queues, reports, and privacy APIs. A lot of it was getting old and new systems to agree long enough for nobody to notice the seam.
