How to write better bullet points
Helped build a new billing system for the company using Node.
Architected and deployed a multi-entity billing engine using Node.js and PostgreSQL to process $1.4M in monthly transaction volume.
It replaces a passive task description with active ownership, specific technologies, and a clear business scale.
Managed the migration of old services to Docker and Kubernetes.
Spearheaded the migration of 8 legacy monolithic services to a containerized microservices architecture, reducing infrastructure costs by $120K annually.
It quantifies the scope of the migration and ties the technical effort directly to a financial outcome.
Mentored junior developers and helped them improve their coding skills.
Mentored 4 junior developers on system design principles, increasing the team's average sprint velocity by 32% over three quarters.
It moves from vague support to a specific mentorship focus with a measurable impact on team productivity.
Senior Full Stack Developer resume writing tips
- Highlight architectural transitions, such as migrating legacy monoliths to microservices, to prove system-level thinking.
- Quantify mentorship by linking it to team-wide metrics like sprint velocity or code review turnaround times.
- Explicitly state the scale of data or traffic your full-stack features handle to demonstrate reliability under load.
Common mistakes
- Listing only features shipped without mentioning the underlying architecture or design decisions that made them possible.
- Omitting the impact of technical leadership, which makes a senior candidate look like a high-output individual contributor instead of a lead.
- Focusing on small-scale UI tweaks rather than end-to-end performance optimizations that affect the entire application stack.
Frequently asked questions
Is this resume right for someone with five years of experience? Yes if you have moved beyond feature execution into designing systems and leading technical initiatives rather than just taking direction.
Yes if you have moved beyond feature execution into designing systems and leading technical initiatives rather than just taking direction.
Yes, if you have moved beyond feature execution into designing systems and leading technical initiatives. No, if your work is still primarily directed by more senior engineers or focused on single-stack tasks.
What if my background is in startups rather than large firms like Goldman Sachs? Focus on scale and complexity; hiring managers value the ability to build robust systems with limited resources or during rapid growth.
Focus on scale and complexity; hiring managers value the ability to build robust systems with limited resources or during rapid growth.
The core signal for this role is the ability to handle scale and complexity regardless of company size. You can emphasize how you built robust systems with limited resources or navigated rapid growth phases.
What if I don't have access to specific dollar amounts like the billing volume shown here? Use proxies for impact like the volume of daily data processed, percentage reduction in latency, or the total number of users affected.
Use proxies for impact like the volume of daily data processed, percentage reduction in latency, or the total number of users affected.
You can use other proxies for impact, such as the number of users affected, percentage reduction in latency, or the volume of data processed daily. In this resume, Rachel Mitchell uses a mix of financial, performance, and team productivity metrics to show a well-rounded impact.
How much should I change before applying? Update the tech stack to match the job description while maintaining achievement bullets that highlight architectural ownership and improvements.
Update the tech stack to match the job description while maintaining achievement bullets that highlight architectural ownership and improvements.
The technical stack should be updated to match the specific requirements of the job description while keeping the structure of the achievement bullets. You should maintain the focus on architectural ownership and leadership even if the specific tools differ.
What do hiring managers focus on at this level? They look for evidence of high-stakes technical decision-making and the ability to elevate the performance of the engineers around you.
They look for evidence of high-stakes technical decision-making and the ability to elevate the performance of the engineers around you.
They look for evidence that you can be trusted with high-stakes technical decisions and that you make the engineers around you better. The focus shifts from proving you can code to proving you can design and lead.
