Launch Recap: What I Learned Building & Launching SkillFitly
An honest recap of building SkillFitly — a free, $0-to-run resume checker — and launching it: what worked, what I'd do differently, and lessons for indie builders.
I built SkillFitly — a free tool that matches your resume to a job description, checks ATS-friendliness, and shows the exact skills you're missing — and just put it in front of real users. This is an honest recap of what I learned building and launching it, for anyone building their own side project.
The idea: solve one annoying, universal problem
Qualified people get auto-rejected by applicant tracking systems because their resume wording doesn't match the job. That's a narrow, painful, universal problem — the best kind to build for. I resisted the urge to make a 'career super-app' and shipped one clear job: paste a JD + resume, get a match score and a fix list.
The constraint that shaped everything: $0 to run
I decided SkillFitly had to cost effectively nothing to operate so I could keep it free. That one constraint drove the whole architecture: keyword/section-based analysis instead of an LLM in the hot path, resumes processed in memory and never stored, and static generation for every content page. The result runs on a free hosting tier and stays free for users — no paywall pressure.
What worked
- Shipping narrow. One clear promise beat a feature pile-up.
- Programmatic SEO. Hundreds of skill, role, and interview-question pages generated from structured data gave search engines a real reason to index the site.
- Privacy as a feature, not a footnote. 'Your resume is never stored' is genuinely reassuring and genuinely true.
- Free-first. No signup for the first analysis removed all friction to trying it.
What I'd do differently
- Start distribution earlier. Content and product were ready before I'd built any audience — ranking and reach lag by months, so the outreach should have started on day one.
- Instrument sooner. Analytics and Search Console should be live before launch, not bolted on, so you can learn from the very first visitors.
- Write the launch copy while building. Drafting the story after the fact is harder than capturing it as you go.
Lessons for other indie builders
- A hard constraint (like $0 cost) is a design tool, not just a limit — it forces simpler, more durable choices.
- SEO is a compounding asset but a slow one; pair it with active distribution to get early signal.
- Ship the smallest honest version, then let real usage tell you what to build next.
Try it and tell me what's missing
SkillFitly is live and free: paste a job description and your resume into the resume checker to see your match score, ATS check, and skill gaps — or build an ATS-friendly resume in the free resume builder. It's an ongoing project, and feedback shapes what I build next.
