Applera - AI powered job applications, tailored to every posting

Sup huntas I built Applera because I was sick of rewriting the same cover letter every single time I applied to a job. It always felt like the boring part of job hunting: same experience, same skills, just repackaged over and over depending on who was reading it. So Applera does that repackaging for you. Upload your CV once, paste in a job listing, and it generates a tailored application built around what that specific role is actually asking for. Once you're through to the interview stage, it also builds you a prep guide based on that job description instead of a generic question bank. One thing I cared about a lot: the matching isn't just "throw everything at an LLM and hope." Applera runs a deterministic scoring pass first, skill matching with alias resolution (so it knows "Node.js" and "NodeJS" are the same thing) plus text overlap. AI only gets called in to refine the match when that score is unclear or low confidence, so it's used deliberately rather than by default. Every CV and job pairing is also cached, so running the same match twice never recomputes from scratch. I also didn't want the classic SaaS friction of a card wall or a demo call before you can even see if the tool is useful. You upload a CV, paste a listing, and you're looking at a tailored application right away. Stack wise it's a TypeScript monorepo, React 19 on the frontend, Express 5 on the backend, Groq for generation, Clerk for auth. Happy to go deeper on any of it in the comments. Would really appreciate your feedback, especially on tailoring quality since that's the part I've iterated on the most and I'm always hunting for edge cases to fix. Thanks for checking it out :)
