Mid-Level Full Stack Web Developer Resume Example
Mid-level full stack web developers get hired when they prove end-to-end feature ownership, not by listing tickets completed without technical context.
This resume is for full stack developers who own end-to-end features and mentor junior peers, but aren't yet responsible for defining technical roadmaps or department-wide engineering strategy.
- End-to-end ownership of significant product features
- Evidence of performance optimization across both frontend and backend
- Contribution to team growth through mentorship or architectural improvements
- Skills categorized by technology stack and infrastructure
- Experience bullets leading with technical actions and business outcomes
- Education and location details positioned for quick scanning

Frequently asked questions
Is this resume right for someone with 3-5 years of experience? Yes if you’ve transitioned from simple bug fixes to owning complete features and making independent technical trade-offs.
Yes if you’ve transitioned from simple bug fixes to owning complete features and making independent technical trade-offs.
Yes, if you have moved past simple bug fixes into owning entire feature sets and making technical trade-offs. No, if you are still primarily working under the direct guidance of a senior lead for every architectural decision.
What if I have only worked on the frontend or backend? Use this template by emphasizing how your deep expertise in one area, such as SQL optimization, directly improves the other side of the stack.
Use this template by emphasizing how your deep expertise in one area, such as SQL optimization, directly improves the other side of the stack.
This template still applies, but you should emphasize how your deep expertise in one area impacts the other side of the stack. In Maya's resume, notice how she connects her backend SQL optimizations directly to frontend page load improvements.
What if I don't have metrics like this? Substitute business metrics with proxy signals like reduced build times, improved code standards, or faster ticket turnaround.
Substitute business metrics with proxy signals like reduced build times, improved code standards, or faster ticket turnaround.
You can substitute hard metrics with proxy indicators like reduced build times, decreased ticket turnaround, or standardized code patterns. The goal is to show that you are measuring the success of your work beyond just verifying that the code runs.
How much should I change before applying? Maintain the impact-heavy structure but swap the specific tech stack and cloud providers to mirror the requirements in the job description.
Maintain the impact-heavy structure but swap the specific tech stack and cloud providers to mirror the requirements in the job description.
Keep the structure of the impact-heavy bullets but swap the specific tech stack to match the job description. If a role emphasizes AWS over Docker, ensure your most prominent bullets reflect your cloud infrastructure experience.
What do hiring managers focus on at this level? Recruiters look for evidence that you can own a feature from ideation to deployment without needing constant senior-level supervision.
