HIEN Marketing Automation

HIEN Marketing Automation addresses a real operational bottleneck for small e-commerce businesses: the manual process of applying branding templates to dozens or hundreds of product images for each social media campaign. The tool transforms this from a per-image manual task (open Photoshop, position template, export, repeat) into a batch automated process that maintains pixel-perfect brand consistency across all output formats.

The template engine overlays brand frames, promotional badges, price callouts, and decorative elements onto product photos with configurable positioning rules. Social media presets encode the exact dimensions and safe zones for Instagram (square and story), Facebook (post and banner), Zalo, and TikTok — output is sized and composed correctly for each platform without manual cropping. Zustand manages the complex template editor state: selected template, active product image, overlay positions, color scheme overrides, and export queue.

Google APIs integration handles content distribution workflows — processed images can be organized and distributed via Google Drive for team access, fitting into the broader content calendar workflow. Sharp handles the image processing pipeline server-side: compositing layers, applying compression, converting formats, and generating web-optimized output files. The result is a marketing workflow that a small team can operate without a dedicated graphic designer for routine social media content production.
