BuiltProof
A recruiting dashboard where engineering hiring managers can review candidates' actual build-from-scratch projects — Redis clones, Git implementations, ray tracers — with AI explanations of what the code does and skill badges auto-generated from the implementation.
Engineering hiring managers and technical recruiters tired of resume-driven candidate screening
- Candidate uploads GitHub repo; AI generates plain-English summary of the architecture and key design decisions
- Skill badges auto-extracted from code (e.g., 'implemented TCP socket handling,' 'built B-tree indexing,' 'wrote a PEG parser')
- Side-by-side candidate comparison across the same project type (e.g., five candidates' Redis clones)
- Interview question generator that probes the candidate's specific implementation choices, not generic trivia
Build-from-scratch learning platforms are trending and producing graduates with verifiable projects; employers are increasingly skeptical of resume claims and want proof of systems understanding
73% of engineering managers consider public repo activity a significant hiring factor and 87% of recruiters review GitHub profiles, confirming strong pull for evidence beyond resumes, though not yet proof of willingness to use a dedicated dashboard over free profile review.Skills-based hiring replaces credentials in tech industry ↗The Complete Guide to Repository Analytics: What Your GitHub Projects ... ↗Hiring managers: do you actually look at portfolios? - Reddit ↗
CodeCrafters already occupies the 'rebuild Redis/Git/SQLite from scratch' niche at $5M ARR and explicitly positions itself for interviews; combined with HackerRank, CodeSignal, CoderPad, and TestGorilla, the buyer is crowded and BuiltProof risks being a feature rather than a category.Build your own Redis | CodeCrafters ↗CodeCrafters Revenue 2024: $5M Est.
