Beyond a generic quiz website
Certification candidates need more than question lists. They need practice under realistic timing, navigation constraints, and format variety, while retaining a clear view of progress across attempts. The opportunity was to unify those needs across many professional certification bodies without turning the experience into a generic multiple-choice quiz.
A modular exam-simulation and learner-progress platform
We designed CertGuru as a modular Vite React application on Cloudflare Pages, backed by Supabase for authentication, PostgreSQL, Row-Level Security, and server-authoritative scoring. Candidates can search and compare certification paths, review exam-specific rules, complete timed attempts across multiple question formats, and return to dashboards that surface attempt history, score trends, streaks, and weak domains — all with answer keys kept out of the public client.
Capability highlights
The engineering and design work behind the product.
Exam-accurate simulation
Timed full attempts with exam-specific counts, durations, flagging, review grids, section gates, and CAT-style behaviour where configured.
50 certification paths
A searchable catalogue across six professional categories, each with an exam-specific introduction and rules.
12 question formats
Multiple-select, matching, hotspot, image hotspot, fill text/numeric, case, practical, and task-simulation — not just radio buttons.
Learner analytics
Attempt history, best/latest/average scoring, animated score trends, streaks, and weak-domain reporting.
Secure administration
MFA/AAL2-gated admin console, subscription enforcement at exam start, complimentary-access keys, and audited privileged actions.
Server-authoritative scoring
Attempt creation, answer submission, and grading run server-side; answer keys are never exposed to the browser.
