CertPath — Credential Gap Tracker That Tells Self-Taught Devs Exactly What to Learn Next
Self-taught developers collect random Udemy certificates like trading cards but have no idea if they are actually closing the gap to their target job. CertPath maps your current credentials against a specific job title, shows exactly what is missing, and builds a week-by-week learning schedule that does not send you down a YouTube rabbit hole for three months.

What is it?
There are 30M+ self-taught developers globally who are stuck in the endless tutorial loop — they learn React, then see a job requiring TypeScript and GraphQL, pivot to those, then see Kubernetes and spiral again. CertPath asks for a target job title and seniority level, pulls the top 50 job postings for that role via SerpAPI, extracts the required skills using Claude NLP, compares them against the user's uploaded certificates and self-reported skills, and outputs a ranked skill gap list with specific free and paid course recommendations and a weekly study schedule. It is a focused, single-workflow tool that solves one problem better than any career coaching spreadsheet. Buildable in two weeks because SerpAPI, Claude API, and Supabase are production-stable and the job posting extraction pattern is a known solved problem.
Why now?
The April 2026 vibe-coding wave has flooded the self-taught developer market — more people than ever are learning to code with AI tools but have no structured way to validate they are learning the right things for real jobs.
- ▸Job posting skill extractor that reads 50 real job listings for a target role and surfaces the most required skills by frequency.
- ▸Gap analysis comparing extracted job skills against uploaded certificates and self-reported skills.
- ▸Week-by-week study schedule with specific free course links for each missing skill.
- ▸Progress tracker that lets users check off completed skills and rescan the job market monthly.
Target Audience
Self-taught developers and career switchers targeting their first or second dev job — estimated 5M+ such learners active on freeCodeCamp, The Odin Project, and r/learnprogramming.
Example Use Case
Dani is a self-taught developer targeting junior React roles in Berlin, uploads her freeCodeCamp certificate and JavaScript course completion, gets a gap report showing TypeScript and testing as critical missing skills, and follows the 6-week schedule CertPath generates to close those gaps before applying.
User Stories
- ▸As a self-taught developer, I want to see exactly which skills I am missing for my target job title, so that I stop learning random things and focus on what matters.
- ▸As a career switcher, I want a week-by-week study schedule based on my specific gaps, so that I have a concrete plan instead of an overwhelming list.
- ▸As a learner, I want the gap analysis to reflect current real job postings, so that I am not studying skills that were required in 2022 but not today.
Done When
- ✓Skill extraction: done when entering a job title returns a ranked list of top 10 required skills sourced from real job postings in under 10 seconds.
- ✓Gap comparison: done when uploading a certificate or adding a skill removes it from the missing skills list immediately.
- ✓Study schedule: done when each missing skill has at least one linked free course with an estimated completion time.
- ✓Payment: done when Stripe one-time checkout completes and the full 20-skill gap report and 6-week schedule appear without page reload.

Core User Journey
Enter target job title -> see free teaser with 3 top missing skills -> pay $9 -> receive full gap report and 6-week study schedule.
Architecture Pattern
User enters job title -> SerpAPI fetches 50 job postings -> Claude extracts required skills by frequency -> user uploads certs or self-reports skills -> gap comparison runs in Supabase -> gap report and study schedule rendered -> Stripe payment unlocks full report.
Data Model
User has many SkillProfiles. SkillProfile has many UserSkills and many GapReports. GapReport has requiredSkills, missingSkills, and StudySchedule. StudySchedule has many WeeklyTasks.
Integration Points
SerpAPI for job posting data, Claude API for skill extraction and NLP, Supabase for user skills and report storage, Stripe for one-time and subscription payments, Resend for report delivery email.
V1 Scope Boundaries
V1 excludes: employer-side matching, cohort features, LinkedIn OAuth skill import, mobile app, certificate verification.
Success Definition
A self-taught developer pays $9, receives a gap report with a study schedule, and starts the recommended course within 48 hours without any founder involvement.
Challenges
Self-taught developers are notoriously price-sensitive — $9 is the ceiling before conversion drops sharply, which caps revenue unless the subscription tier retains well.
Avoid These Pitfalls
Do not hand-curate course recommendations — link to freeCodeCamp, The Odin Project, and MDN by skill keyword so it stays evergreen. Do not skip the free teaser — showing 3 missing skills before the paywall is the conversion moment. Finding your first 10 paying users takes active forum participation, not SEO.
Security Requirements
Supabase Auth with Google OAuth. RLS on GapReport rows by userId. Rate limiting 30 req/min on scan endpoint. Certificate filenames only stored, no file content retained.
Infrastructure Plan
Vercel for Next.js, Supabase for Postgres and Auth, Cloudflare R2 for certificate uploads if needed, Sentry for errors, GitHub Actions for CI.
Performance Targets
300 DAU at launch. Job scan and skill extraction under 8 seconds. Dashboard load under 2s. SerpAPI call cached per job title for 48 hours to reduce cost.

First Run Experience
On first run: landing page shows a demo gap report for a junior React developer role pre-generated with 8 missing skills and a 6-week study schedule. User can immediately browse the demo report before signing up. No manual config required: demo data is hardcoded JSON, no API calls needed on first load.
How to build it, step by step
1. Define Supabase schema for User, SkillProfile, GapReport, and StudySchedule tables. 2. Build SerpAPI route that fetches 50 job postings for a given job title and location. 3. Write Claude prompt that extracts required skills from job posting text and ranks by frequency. 4. Build skill input UI where users add their current certificates and skills. 5. Write gap comparison function that diffs job skills against user skills and returns ranked missing list. 6. Build study schedule generator that maps missing skills to curated free course links. 7. Wire Stripe one-time payment that unlocks full report beyond the 3-skill teaser. 8. Build report page with gap visualization and downloadable PDF via html-to-pdf. 9. Seed demo account with a pre-generated junior React developer gap report. 10. Verify: enter a real job title, confirm 50 postings are fetched, pay $9, receive full gap report with study schedule in under 60 seconds.
