A privacy-first Windows desktop app for automatic speech recognition (ASR) / speech-to-text (STT). Qevoxyl runs Whisper offline, ships with an FFmpeg shim, and offers a clean CustomTkinter UI with optional Online TTS playback. Built for per-user installs (no UAC), with right-click Explorer integration and an AV-friendly one-folder packaging approach.

• Offline Whisper (PyTorch) with local model caching and GPU fp16 when available.
• FFmpeg hardening: resolves via imageio-ffmpeg; local fallback copy to models/ffmpeg-bin.
• Explorer context menu: “Transcribe with Qevoxyl” for .wav/.mp3.
• Per-user install: Inno Setup to %LOCALAPPDATA%\Qevoxyl (no admin/UAC).
• One-folder PyInstaller build with version info + manifest; UPX disabled for stability.
• Session guard & reset: cancel in-flight work, start new session, and keep the UI responsive.
• Persistent settings: appearance, model selection, and Online TTS toggle in settings.json.

I developed and deployed a production-grade web application for Teaching Practice Posting and Letter generation, hosted at oouteachingpractice.name.ng. The platform streamlines student posting, school capacity management, approval workflows, and printable posting letters.

• Core Stack: PHP (with MySQLi prepared statements), JavaScript (ES6), AJAX, HTML/CSS, Python utilities.
• Admin Dashboard: Manage schools, courses, student enrollments, capacities, and assignments with search, filters, pagination.
• Data Ops: CSV import/export (schools, courses, students), bulk actions, and change logs for auditability.
• Capacity Rules: School capacity enforcement, live counts per school, safe rename/cascade handling.
• Student Portal: Secure enrollment lookup (by matric), posting confirmation, and printable/postable letters (PDF/print-friendly).
• Real-time UX: AJAX modals and toasts for edits, validations, and status updates without full page reloads.
• Security & Reliability: Server-side form-status checks (prevents UI tampering), input validation, prepared queries, role-based access.
• Insights: Dynamic charts for departments/levels/schools (Chart.js) and downloadable reports.
