Things I've built, written down.
Short technical write-ups from real projects. No fluff, no theory, just what worked.
- 01 Routing invoices through SQS, Lambda, and an AI server How Flowbills moves an invoice from an inbox to structured data: SES to S3, Lambda as the router, SQS between every hop, and a Python AI server for the messy files.
- 02 Filtering free-form WhatsApp queries with Mistral AI The FleetTrack bot listens in WhatsApp groups where users report fleet issues in whatever format they like. Mistral AI turns that mess into something the backend can act on.
- 03 Routing SMS across two SIMs: a local gateway and FloLive The same FleetTrack bot sends SMS through two very different paths: a local SIM driven by the SMS-gate app, and a cross-border SIM managed through the FloLive portal.
