About CodeQuest — Interactive Frontend Developer Assessment Platform

frontend interview-style simulation with Monaco debugging, scored challenges

CodeQuest is a ready-to-deploy interactive frontend engineering assessment platform built with React + TypeScript. It turns traditional coding assessments into a short, game-like engineering simulation where developers make real-world technical and product decisions. Candidates progress through challenges covering production debugging, React, performance optimization, accessibility, and product trade-offs, finishing with a scored engineering review. Unlike a static coding quiz or portfolio project, CodeQuest simulates how a frontend engineer thinks under realistic constraints. Potential customers include recruiting teams, technical hiring platforms, coding bootcamps, engineering courses, and companies conducting frontend interviews. The MVP is already built and deployable, with scoring, interactive challenges, Monaco code editor integration, Firestore logging, tests, Firebase deployment setup, and transfer documentation. Pre-revenue and ready for a new owner to expand the challenge library, add accounts and candidate reports, and monetize as an assessment or training product.

Next step: CodeQuest can be expanded from the current MVP into a technical assessment or developer-training business. Hiring SaaS: Add company accounts, candidate invitations, timed assessments, candidate reports, and recruiter dashboards. Developer training: Add more frontend challenges covering React, TypeScript, debugging, accessibility, performance, testing, and system-design decisions. Bootcamps & education: License CodeQuest to coding bootcamps or courses as an interactive assessment and practice platform. White-label: Offer branded assessments to recruiting agencies, bootcamps, and companies. AI evaluation: Integrate an LLM API to provide more detailed feedback and personalized engineering reviews. Accounts & competition: Add authentication, saved attempts, achievements, leaderboards, and progress tracking. The current MVP already includes the interactive challenge flow, scoring system, code-editor experience, deployment setup, and UI foundation, allowing a buyer to focus on content, customer acquisition, and monetization rather than starting from zero.

Reason for selling

I built CodeQuest as an interactive alternative to traditional frontend coding assessments and brought the concept to a functional, deployable MVP. My focus is now on other projects, so I'm looking for a buyer who can expand the content, market it to developers or hiring teams, and develop it into a larger assessment or training product.
