Show HN: How I built a resume editor using AI with zero web dev experience

Built a resume editor with AI and zero web dev experience. Show HN + demo: https://www.tailortojob.app/ Stack: Vercel, Render, Supabase. Timeline: ~180–200 hours over 4 months. Take: agents accelerate feature code — but infra, glue, and decisions still eat time. What actually worked: a high/low model split. Use a larger model (author used Opus 4.6) to plan in Markdown, then smaller models to implement. Reality check: agents hallucinate API availability — feed them current API docs or they’ll suggest non‑existent models. UI lesson (and money saved): spent 5 hours on an interactive tutorial nobody used. Take: instrument first. Prefer inline affordances, defaults, and tiny examples. Measure clicks/abandonment before investing in long tutorials or hand‑holding. For builders/agencies: agents buy you velocity, not ownership. Quick checklist: 1) host, DB, auth in place 2) plan with a big model 3) split coding to smaller models 4) feed live API docs 5) instrument UX 6) keep a human approval st
