EXPERIENCE
Full-stack — NDA (marketing-analytics SaaS, 6 production products) Jan 2024 – Present
Remote
• Architected a shared modular component library and distributed it as an internal npm package, eliminating code
duplication and enabling cross-functional teams to independently ship UI updates across 6 production codebases.
• Transformed a manual support process into a self-service flow by engineering a unified integration architecture,
reducing related support tickets by an estimated 30% while enabling customers to autonomously link Facebook,
Google Ads, TikTok, and CRMs.
• Successfully led the platform through Meta App Review by implementing the required privacy and compliance
workflows, ensuring uninterrupted Facebook Ads integrations and eliminating the risk of API access suspension
for customer ad accounts.
• Decoupled marketing operations from engineering by integrating a headless CMS, saving over 10 engineering
hours monthly and enabling marketers to independently publish bilingual content without code releases.
• Eliminated dependency on backend queues by independently engineering Node.js API routes, database schemas,
and deployment configurations for 5 core integrations, including Google Ads, Google Analytics, Pipedrive, Meta
Ads, and TikTok.
