Most Nigerian students prepare for JAMB and Post-UTME with random PDFs and no clear path after the exam. I built Propeida to fix that. It is a full web application with timed mock exams, verified questions, student progress tracking, dual dashboards, and Paystack integration for optional upgrades. Over 250 students now use it regularly to practice and explore real career options connected to their courses. The platform feels light on data, works smoothly on any phone, and finally connects exam preparation to what comes next.
250+ students actually using it regularly is the real proof point here — most exam-prep side projects never get past the demo stage. Dual dashboards + Paystack for upgrades is a smart monetization layer on top of a genuinely useful free tool. How are you handling the timed mock...
React plus Supabase is a solid combo for this, row level security handles the per student data isolation without much custom backend work. I run the same stack for BookBed, and Paystack integration was actually one of the easier parts once the webhooks were mapped out correctly....
Thanks for the solid breakdown, Dusko! Hearing that from someone running a similar stack on BookBed is encouraging. For the timed mock exams, I'm using a React state countdown backed by server-side timestamps to ensure fairness and prevent any timer manipulation if a student refreshes. Really appreciate the feedback

This UI was really great nice job Piotr🔥🔥🔥
Hello everyone, this is a prototype of a B2B Marketplace that can help construction companies sell more, manage easily supplier contacts and quotes request from theirs clients, the platform can be adapted to many fields in construction starting from metal to interior home suppliers. reach me out if you think this is useful for your business so i can customize it for you 😊
Quote requests usually need a status per supplier—sent, answered, revised or expired—so buyers can compare offers in one place. Did you model each supplier’s response separately from the original request?
An interaction study for Mare’s collection feed, exploring how to make groups legible within a dense, mixed-format archive.
The layout preserves image proportions and integrates collection labels into the packing system. On hover, image-derived gradients establish the collection boundary, while subtle displacement creates space around the active group without changing its position or scale.
The motion studies isolate assembly, packing, colour and proximity, using real collection content to examine timing, spatial continuity and hover behaviour.
