Senior Software Engineer • Philippines (UTC+8)

I'm Christian Dave Montalban, a senior software engineer focused on accelerating platform and product velocity across mobile, web, and cloud teams.

At Vitable I led the migration from a monolith to AWS microservices, orchestrated Shopify and Tapcart transitions, and modernized our React Native apps on Expo with zero downtime and a 40% runtime gain.

I enjoy building guardrails that let teams ship faster—Bitbucket CI/CD automation, Sentry-driven feedback loops, and AI-assisted QA workflows that keep releases resilient.

Impact highlights

  • Backend platform modernization: Directed the shift from a PHP monolith to AWS microservices with event-driven messaging, service guardrails, and architecture reviews that improved release agility and reliability.
  • Composable APIs for mobile velocity: Designed BFF layers and GraphQL gateways feeding Shopify and Tapcart experiences, pairing caching + observability to deliver 40% faster mobile runtimes without downtime.
  • Delivery guardrails & observability: Built Bitbucket CI/CD with gated checks, infrastructure-as-code, contract tests, and AI-assisted QA triage—cutting release cycles 60% while raising code quality 20%.
