How to write better bullet points
Helped build the real-time sync engine using WebSockets.
Architected a real-time sync engine using WebSockets and Node.js, reducing client-server synchronization latency by 42% for concurrent users.
It transitions from passive participation to active architectural ownership with a quantified performance outcome.
Mentored junior developers on the team.
Mentored 4 mid-level engineers through weekly system design reviews, resulting in the adoption of standardized TypeScript patterns.
It provides a concrete number of mentees and a specific organizational outcome rather than a vague activity.
Improved the search service and database speed.
Optimized SQL query execution plans for the search service, decreasing database CPU utilization by 34% during peak traffic hours.
It specifies the technical method used and the exact impact on system resources during critical load times.
Senior Full Stack Engineer resume writing tips
- Highlight architectural decisions where you chose specific technologies to solve scaling or performance problems.
- Include specific outcomes of your mentorship, such as team-wide adoption of new standards or junior engineer promotions.
- Focus on end-to-end ownership of features that impact both the frontend user experience and backend efficiency.
Common mistakes
- Focusing only on feature delivery rather than the underlying architecture or system design decisions that enabled them.
- Omitting mentorship and leadership contributions because they don't feel like 'technical' work to the candidate.
- Listing a long list of tools without showing how they were integrated to solve a complex business challenge.
Frequently asked questions
Is this resume right for someone with 5-7 years of experience? Yes if you’ve moved from execution to leading technical direction and mentoring; no if you are still primarily focused on completing assigned tasks.
Yes if you’ve moved from execution to leading technical direction and mentoring; no if you are still primarily focused on completing assigned tasks.
Yes, if you are moving from individual execution to leading projects and mentoring others. No, if you are still primarily focused on completing assigned tasks without influencing technical direction.
What if my background isn't in high-growth startups like Discord or Linear? Yes, emphasize the complexity of the problems you solved and how you introduced new technologies to improve your existing team's systems.
Yes, emphasize the complexity of the problems you solved and how you introduced new technologies to improve your existing team's systems.
You can still use this structure by focusing on the complexity of the problems you solved. Emphasize how you improved existing systems or introduced new technologies to your current team to drive efficiency.
What if I don't have access to specific latency or conversion metrics? Frame impact through scale, such as user volume or data throughput, if you lack access to specific latency or conversion metrics.
Frame impact through scale, such as user volume or data throughput, if you lack access to specific latency or conversion metrics.
In this resume, Ali quantifies performance gains, which is the level of specificity recruiters expect. If you lack metrics, frame impact through scale, such as the number of users affected or the volume of data processed.
How much should I change before applying? Maintain the impact-heavy structure but swap the tech stack to match the job description and specific libraries requested by the employer.
