I built AimVantage — an AI tool that turns your CV + a job link into a full interview prep pack in 90 seconds

Job applications are brutal. Company research, CV tailoring, cover letter writing, interview prep -- each one eats 45-60 minutes. Multiply that by 10-15 applications a week and you've lost your entire week.

I built AimVantage to fix this. Upload your CV, paste a job link. 90 seconds later you get:

  • Company intelligence brief -- culture signals, recent highlights, auto-extracted from the job URL
  • CV fit score -- match points, gaps, closing moves
  • Tailored cover letter in 4 tones -- Direct, Formal, Warm, Creative
  • Mock interview questions with model answers
  • 5-minute pitch outline for the opening of your interview

One workflow replaces Jobscan ($49.95/mo) + Final Round AI ($99/mo) + manual Glassdoor research. AimVantage starts at $5 one-time.

The tech

Built solo in 53 days:

  • React 19 + TypeScript + Vite 6 -- 72,735 lines of code, 92 components
  • Gemini 2.5 Flash for all AI generation (not GPT -- Gemini is faster and cheaper for structured output)
  • Stripe LIVE with multi-currency (GBP + USD), webhook idempotency
  • Vercel serverless -- 10 API endpoints
  • Supabase for auth + database
  • 334 passing tests, zero TypeScript errors

The entire thing runs on ~$1/month in free-tier infrastructure.

20 free tools (no signup)

Built 20 standalone tools as an acquisition funnel. These work instantly, no account needed:

141 blog posts

Company-specific interview prep for 100+ employers (Stripe, Anthropic, Google, Meta, Amazon, Revolut, Monzo...). 19 interview question role packs. 9 honest competitor comparisons. All with JSON-LD structured data so AI search engines can cite them.

72,735 lines of code for AimVantage is a huge solo project! It's impressive that it runs smoothly on free-tier infrastructure for just $1/month. I see the appeal of automating the prep process, but I'm skeptical about AI-generated company briefs being as useful as real research. For coding interviews, I've been using LeetCode for DSA, but recently, PracHub has become my favorite for technical rounds. Their question banks are pretty close to what actually gets asked.
