Projects by Ralph Jonas Mungcal
the work i'm proudest of — payments, search, scrapers, and ai pipelines. each one has a write-up.
- flight-rewards-search node · ts · postgres · gcp
reward flight availability search across major airlines — node.js and typescript backend, postgresql search index, and gcp ingestion pipelines.
- billing-payment-platform node · ts · gcp · event-driven
payment orchestration across multiple gateways with unified subscription billing, dunning, and smart retries — typescript on an event-driven gcp stack.
- subscription-event-bus node · gcp · pub/sub
event-driven subscription billing on gcp pub/sub — lifecycle fan-out, idempotent consumers, retry policies, and dead-letter handling under load.
- ai-meeting-editor python · whisper · deepgram · ffmpeg · pytorch · aws
ai meeting editor that detects where a discussion really starts and ends, trimming dead air with whisper, deepgram, ffmpeg, and pytorch on aws.
- ai-dev-workflow-standards claude · openai
internal standards for ai-assisted development — agent setup, prompt patterns, and review gates that keep claude and openai coding consistent across a team.
- airline-data-bots ts · puppeteer · bullmq
scheduled scrapers collecting flight availability from multiple airline sources — typescript and puppeteer with bullmq job scheduling and retries.
