About

I just pushed my latest launch live: DecaJob.Like many developers and analysts, I've experienced the exhaustion of the modern job search. Platforms like LinkedIn and Indeed have turned into infinite-scrolling feeds full of sponsored listings, expired posts, and ghost jobs. It forces you to apply to 100+ positions a day just to get a single rejection email.I wanted to fix this fatigue by creating a product focused on constraint and quality.How DecaJobs Works:The Constraint: Instead of searching through endless listings, candidates get exactly 10 highly-targeted, AI-matched jobs delivered to their inbox every morning.The Tools: We also built-in an AI Resume Scorer, AI Cover Letter Optimizer, and an AI Career Coach to help candidates write high-intent, targeted applications rather than bulk-spamming.Pricing: A 7-day free trial, then a ₹299/month Pro subscription.The Technical Challenges (and how we solved them):Since the daily digest matches job listings against candidate resumes dynamically, sourcing external jobs (using parallel APIs) and scoring them takes about 1.5 seconds per user.During early tests, running this sequentially for all candidates inside a single serverless worker function caused execution to exceed 10 seconds, crashing on Vercel (serverless timeouts).The Fix: We refactored our worker architecture to use Inngest's Fan-Out pattern. Now, our main daily cron function takes less than 1 second to fetch candidates and dispatches parallel, isolated events for each user. A candidate-specific worker handles the scoring and email delivery in under 2 seconds. It scales infinitely for pennies on the dollar!Our tech stack is Next.js, Supabase (for database & Auth), Inngest (for background workers & crons), Google Gemini (for resume analysis/scoring), and Resend (for emails).What's Next:Our goal is to reach our first 100 paid subscribers.I’d love for you to check it out at decajob.com, run your resume through the scorer, and let me know:Does the 7-day free trial onboarding feel friction-free?How is the matching accuracy for your specific skills?
