ESP32-S3 E-Reader — Splash, Ukrainian UI & Re-branded Book Upload (BlinkRead)

BlinkRead is a pocket speed-reading device on the Waveshare ESP32-S3-Touch-LCD-3.49 (rev1). This is NOT a from-scratch build. A working firmware base for this exact board already exists (open-source, MIT) and will be provided. It already includes the word-by-word RSVP reading engine and an on-device book-upload page. I only need 3 small additions/changes on top of it: 1. Boot splash — show a fixed BlinkRead image on power-on (high-quality file provided). Simple decode and display. 2. Ukrainian language — Ukrainian interface (menus, buttons) + correct rendering of Ukrainian text in books (full Cyrillic incl. Ґ Є І Ї, UTF-8, embedded font subset). 3. Re-brand the existing upload page — the device already serves a Wi-Fi upload page; re-style it as BlinkRead (logo, Ukrainian “Додати книгу” button) and remove original names/links from the user-facing parts. Please review the BlinkRead website first to understand the intended look and upload logic. All user-facing parts must show only BlinkRead branding. The MIT notice stays in the source code (not on screen). Effort: roughly 1.5–2 days of work on an existing, working codebase, not a ground-up project. Hardware: I have the board. You send compiled builds, I flash them and send back video/photos for feedback. Deliverables: documented source, compiled .bin, short README, quick demo (book uploaded from phone + laptop). Please share relevant ESP32 + touchscreen work, and your price + timeline for this scope.
