Mid-Level Web Developer Resume Example
A mid-level web developer resume is evaluated on feature ownership measured by developer velocity, not task execution under constant supervision.
This resume is for web developers who own full-feature lifecycles and optimize application performance, but aren't yet responsible for defining the technical roadmap or managing entire engineering departments.
- End-to-end ownership of complex features or services
- Evidence of technical decision-making that improves performance or developer velocity
- Successful collaboration across teams and informal mentorship of peers
- Professional experience listed in reverse-chronological order
- Technical skills categorized by language and infrastructure
- Bullet points lead with specific metrics and technical outcomes

How to write better bullet points
Built a component library for the front-end team.
Engineered a reusable React component library for the template editor, reducing front-end development cycles for 6 product teams by 24%.
It specifies the technology and quantifies the massive efficiency gain for the broader engineering organization.
Improved database performance for the audit service.
Refined database indexing strategies for the audit log service, decreasing query latency by 42% for high-volume enterprise accounts.
It identifies the specific technical action taken and the resulting performance improvement for a specific user segment.
Helped junior developers with their code.
Mentored 2 junior engineers on modern TypeScript patterns and established new documentation standards for internal API consumption.
It demonstrates leadership and the creation of lasting team assets rather than just passive assistance.
Mid-Level Web Developer resume writing tips
- Link technical tasks to team-wide benefits, such as reducing development cycles or technical debt.
- Highlight instances where you improved system performance using specific metrics like LCP or query latency.
- Include examples of informal leadership, such as establishing documentation standards or mentoring junior engineers.
Common mistakes
- Listing only technologies used without explaining the scope of ownership for the features built with them.
- Over-emphasizing minor bug fixes instead of large-scale initiatives like migrating legacy architectures or launching new services.
- Failing to show growth between roles, such as moving from task execution to leading cross-functional feature launches.
Frequently asked questions
Is this resume right for someone with 3 to 5 years of experience? Yes if you have moved from ticket implementation to owning entire services; no if you still require constant supervision for technical decisions.
Yes if you have moved from ticket implementation to owning entire services; no if you still require constant supervision for technical decisions.
Yes, if you are moving beyond simple ticket implementation toward owning entire features or services. No, if you are still working under constant supervision without making independent technical decisions.
What if my experience is primarily in front-end or back-end rather than full-stack? Yes, adapt the structure by swapping full-stack examples for deep-dives into your specific domain while maintaining the focus on measurable impact.
Yes, adapt the structure by swapping full-stack examples for deep-dives into your specific domain while maintaining the focus on measurable impact.
You can still use this structure by emphasizing the depth of your impact within your specific domain. Simply swap the full-stack examples for deep-dives into your specialization while keeping the focus on ownership and metrics.
What if I don't have access to specific percentage improvements like the ones shown? Use proxy metrics like the number of users impacted, reduction in manual steps, or the frequency of a service call to demonstrate scale.
Use proxy metrics like the number of users impacted, reduction in manual steps, or the frequency of a service call to demonstrate scale.
You can use proxy metrics such as the number of users impacted, the frequency of a service call, or the reduction in manual steps. In this resume, Rachel Parker uses a mix of user counts and performance percentages to build credibility.
How much should I change before applying? Retain the action-to-outcome bullet structure, but swap the specific technologies and scale to reflect your actual professional experience.
Retain the action-to-outcome bullet structure, but swap the specific technologies and scale to reflect your actual professional experience.
Keep the structure of the bullets that link action to outcome, but replace the specific technologies with your own stack. Ensure you adjust the scale of the achievements to reflect the actual size of the user bases you have supported.
What do hiring managers focus on at this level? Managers look for independent technical decision-making and signs of senior-readiness, such as architecture choices and informal peer mentorship.
