Department of Computer Science to Website

A world-class single-file departmental website powered entirely by Google Sheets as a live backend. All content — staff, news, events, documents, alumni — updates instantly when staff edit a Google Sheet. Built as sole designer, developer, and project lead.

• Dynamic settings sheet for stats, WhatsApp, contact details — zero code changes needed
• Password-protected admin panel: create, edit, delete calendar events synced to Google Calendar
• Skeleton loaders, dark mode, mobile hamburger menu, countdown badges, print stylesheet
• Alumni registration, student project showcase, upcoming events with Nigerian WAT time
• Stack: HTML5/CSS3/Vanilla JS · Google Apps Script · Google Calendar API · Cloudflare Pages · GitHub

Capstone Project Portal

End-to-end management of final-year projects: topic submission, supervisor clearance, payment tracking, panel acceptance, and automated email notifications — all without a traditional database.

• Role-based dashboards: student, supervisor, coordinator
• Real-time topic uniqueness check, drop/resubmit, full audit log
• Secure token-based password reset (30‑minute expiry)
• Automated email alerts via Resend API for all workflow stages
• Stack: Flask · gspread (Google Sheets API) · Bootstrap 5 · Resend · Render

Research Participation Portal

A multi‑study web platform for computing education research. Enables researchers to deploy custom studies with surveys, pre/post‑tests, interactive puzzles, bilingual instruction, weekly reflections, automatic resume, and certificate generation. Currently hosts three active studies, with a flexible architecture that supports both JSON‑driven configuration and custom extensions for advanced study designs.

• AlgoLadder – bilingual computational thinking tutor with pre/post‑tests and a 7‑day delayed post‑test. Participants learn algorithm design through scaffolded puzzles.
• Impostor Phenomenon – survey‑only study (Clance IP Scale, MSLQ, engagement & belonging) adapted to the Nigerian context from an international multi‑institutional study led by Prof. Andrew Petersen (University of Toronto Mississauga).
• Professional Dispositions – new study examining collaborative, meticulous, persistent, and self‑directed behaviours. Features a pre‑survey, four weekly time‑locked reflections (each with Likert and open‑ended questions), and a post‑survey. Completed studies are automatically filtered from the "My Certificates" page until all phases are done.
• Recent enhancements: weekly reflection time‑locking with DD/MM/YYYY date display for Nigerian participants; dynamic institution/programme drop‑downs (with fallback lists); robust resume logic that restores reflection week and post‑survey answers; inline certificate download/print handlers for reliable operation across all studies.
• JSON‑driven study configurations for standard survey and puzzle studies; the platform is extensible to support custom phases (e.g., weekly reflections) with minimal code additions.
• Global registration, automatic resume across sessions, admin dashboard with statistics, enrolment control, and email reminders.
• Ethics‑ready: consent, anonymisation, randomisation, attention checks.
