Problem

Preparing app-store screenshots is a manual, repetitive release chore involving device setup, manual navigation, copy editing, and manual graphic splicing.

Solution

An automated developer tool combining ADB deep-link screen routing, signature-based screen stabilization, background job concurrency, and Puppeteer HTML/CSS rendering for repeatable release screenshots.

Responsibilities

• Built Node.js CLI and local browser UI for managing configs, capture runs, previews, and Play Store upload workflows.
• Designed deep-link scene navigation and ADB md5sum signature-based screen stabilization loops.
• Integrated Puppeteer headless browser rendering for high-resolution HTML/CSS screenshot templates.
• Added Play Store API integration for direct metadata and asset uploads.

Achievements

• Automated full screenshot generation pipeline from deep links to final store assets.
• Reduced screenshot generation time from hours of manual work to seconds.
• Supported localized titles, multi-slot device frames, and direct Play Store upload automation.
