Your Prompt
prompt.txt
Optimize my developer resume for Senior Full-Stack Engineer positions at Series A-C startups and mid-size tech companies. My experience level: 5 years.

Current resume content:
[resume_content]

Optimize by:
1. **Rewrite bullet points** using the XYZ formula: "Accomplished [X] as measured by [Y] by doing [Z]"
2. **Quantify impact** — add metrics where possible (%, $, users, latency reduction)
3. **ATS optimization** — ensure keywords match Senior Full-Stack Engineer job descriptions: React, Node.js, TypeScript, AWS, PostgreSQL, system design
4. **Technical projects section** — rewrite 3 projects with:
   - Problem it solved (business context)
   - Your specific contribution
   - Tech stack and architectural decisions
   - Measurable outcomes
5. **Skills section** — organize by proficiency: Expert / Proficient / Familiar
6. **Red flags** — identify anything that hurts my chances and suggest fixes
7. **Summary/headline** — write a compelling 2-line professional summary

Output the complete optimized resume in clean markdown.

What this prompt does

This prompt runs your raw resume content through a structured rewrite pipeline built around the XYZ impact formula — "Accomplished X, measured by Y, by doing Z." That single constraint forces every bullet point to carry a result, not just a responsibility. Vague lines like "worked on backend APIs" become "Reduced API p99 latency by 38% by migrating synchronous DB calls to Redis-backed async queues."

Beyond bullet rewrites, it addresses ATS specifically — you supply the target role and key skills, and the output aligns your language to what parsing systems and hiring managers are actually scanning for. The technical projects section is the most differentiated piece: instead of listing a tech stack, it frames each project around a business problem, your individual contribution, and a measurable outcome. That shift from "what I built" to "what it changed" is what separates resumes that get callbacks from resumes that get archived.

When to use it

  • You are applying for a senior or staff role and your current resume reads like a job description, not an achievement record
  • You are switching from agency/freelance work to product companies and need to translate client work into product-relevant framing
  • Your resume has passed zero ATS screens for a role you are clearly qualified for and you need a diagnostic plus rewrite
  • You are applying to FAANG-adjacent companies where the bar for quantified impact in bullet points is explicit and well-documented
  • You just shipped a major project and want to capture it while the metrics are fresh before it gets diluted into a generic line item

Example output

For a mid-level backend engineer targeting fintech startups:

**Senior Backend Engineer**

• Reduced payment processing failure rate from 3.2% to 0.4% by replacing synchronous
  Stripe webhook handling with an idempotent queue-backed retry system (Laravel Horizon + Redis)

**Projects**

### Real-Time Fraud Detection Pipeline
Problem: Client's manual review team was reviewing 100% of flagged transactions —
8-hour average review time blocked legitimate users.
Contribution: Designed and implemented a scoring microservice in Go that consumes
Kafka events and applies rule-based + ML thresholds.
Stack: Go, Kafka, PostgreSQL, Docker, deployed on AWS ECS
Outcome: Automated 74% of decisions; avg review time dropped to 22 minutes

Pro tips

  • Set [experience_level] accurately — "mid-level" and "senior" generate different emphasis. Senior output leads with architecture decisions; mid-level leads with delivery and ownership
  • For [key_skills], copy-paste 5-8 skill phrases verbatim from 3 real job postings you are targeting. ATS matching is literal, not semantic
  • Run the output back through the prompt a second time with a tighter [target_role] after you see the first draft — iteration sharpens specificity
  • The red flags section is the most honest part of the output; read it before you edit the rewrites. It surfaces ordering problems, unexplained gaps, and overloaded tech lists that hurt more than help
  • Pair this with a cover letter prompt that references the same [company_type] variable — consistency between resume framing and cover letter framing is a signal most candidates miss

Frequently Asked Questions

Does this prompt work if I do not have strong metrics for my bullet points?
Yes. The XYZ formula still applies even without hard numbers — you can express scale ("across a team of 12"), frequency ("reduced a 4-hour manual process to under 20 minutes"), or scope ("sole engineer responsible for..."). The prompt's instruction to 'add metrics where possible' means it will use what you give it and flag where you should go find the real number before submitting.
How much resume content do I paste into [resume_content]?
Paste everything — full text, all sections. The prompt needs your actual bullet points and project descriptions to rewrite them; summaries or abbreviated versions produce shallow output. If your resume is long, that is fine. The model processes the full context and applies the XYZ and ATS passes across all of it.
Will the output be ready to submit or does it need editing?
Treat it as a strong first draft, not a final submission. The rewrite will often over-metric things you cannot verify or attribute contributions more cleanly than is entirely accurate. Read every bullet against your actual memory of the work. The framing is right; the facts need your review. Ten minutes of editing a solid draft beats two hours rewriting a bad one.
