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.
