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
- Platform modernization: Directed end-to-end migration from a monolith to AWS microservices, introducing service guardrails and architectural reviews that improved release agility.
- Mobile velocity: Transitioned React Native and web experiences to Shopify and Tapcart plus upgraded Expo SDK 36→50 without downtime, delivering a 40% runtime performance lift.
- Delivery guardrails: Built Bitbucket CI/CD with gated checks, trunk-based workflows, and AI-assisted QA triage—cutting release cycles 60% while raising code quality 20%.
