개발자 영향의 6가지 유형

Source: Dev.to

1. 기능, 버그, 그리고 기술 작업 배포

What it is: The features you build, the bugs you fix, the technical work that ships to production.
What it is: 당신이 만든 기능, 수정한 버그, 프로덕션에 배포되는 기술 작업.

Why it matters: This is the most visible work. It’s what users see, what product teams request, and what leadership tracks.
Why it matters: 가장 눈에 띄는 작업이며, 사용자가 보는 것이고, 제품 팀이 요청하며, 리더십이 추적하는 항목입니다.

How to document it:

• Focus on business impact, not just technical implementation.
• Answer: What problem did this solve? Who did it help? What metrics improved?

How to document it:

• 기술 구현만이 아니라 비즈니스 영향에 초점을 맞추세요.
• 다음 질문에 답하세요: 어떤 문제를 해결했나요? 누구에게 도움이 되었나요? 어떤 지표가 개선되었나요?

Examples

• ❌ Vague: “Built user dashboard”
  ✅ Clear: “Built a user analytics dashboard that surfaced usage patterns and feature adoption metrics. The product team now uses it daily to inform roadmap decisions, reducing the time to identify underperforming features from weeks to minutes.”

• ❌ Vague: “Fixed payment processing bug”
  ✅ Clear: “Identified and resolved a race condition in payment processing that was causing 2–3 % of transactions to fail. This recovered ~$45 K in monthly revenue and eliminated 30+ weekly support tickets.”

Pro tip: Keep a running log of PRs you ship. Note the business context, not just the technical changes. Tools like BragDoc’s achievement extraction can capture this from your Git history automatically.

2. 멘토링, 코드 리뷰, 그리고 지식 공유

What it is: Code reviews, pair programming, onboarding new team members, writing documentation, answering questions, giving tech talks.
What it is: 코드 리뷰, 페어 프로그래밍, 신규 팀원 온보딩, 문서 작성, 질문 답변, 기술 발표 등.

Why it matters: Senior developers are force multipliers. Your ability to accelerate others is often more valuable than your individual output.
Why it matters: 시니어 개발자는 생산성을 크게 높이는 역할을 합니다. 다른 사람을 빠르게 성장시킬 수 있는 능력이 개인적인 산출물보다 더 큰 가치를 가집니다.

How to document it:

• Quantify the time and scope.
• Name the people you helped and what they accomplished as a result.

How to document it:

• 시간과 범위를 수치화하세요.
• 도움을 준 사람과 그 결과 달성한 성과를 명시하세요.

Examples

• ❌ Vague: “Mentored junior developers”
  ✅ Clear: “Mentored two junior engineers through their first production features, spending 4–5 hours per week on code reviews, pair programming, and 1‑on‑1 technical guidance. Both engineers now contribute independently and have taken on increasingly complex work.”

• ❌ Vague: “Improved documentation”
  ✅ Clear: “Wrote comprehensive onboarding docs for our GraphQL API after noticing new engineers spent 2–3 days ramping up. New team members now become productive in under a day, and the docs are referenced 50+ times per month by the broader engineering team.”

Pro tip: Track code reviews separately. Example: “Reviewed 120+ PRs this quarter, averaging 1–2 hours daily. Provided detailed feedback that improved code quality and caught 3 security issues before they reached production.”

3. 시스템 설계, 아키텍처, 그리고 기술 전략

What it is: System design, technology choices, technical strategy, refactoring, reducing technical debt, setting technical direction.
What it is: 시스템 설계, 기술 선택, 기술 전략, 리팩토링, 기술 부채 감소, 기술 방향 설정 등.

Why it matters: These decisions compound over time. Good architecture enables faster development; bad architecture creates years of pain.
Why it matters: 이러한 결정은 시간이 지날수록 누적됩니다. 좋은 아키텍처는 개발 속도를 높이고, 나쁜 아키텍처는 수년간의 고통을 초래합니다.

How to document it:

• Explain the problem, the options you considered, why you chose what you did, and the long‑term impact.

How to document it:

• 문제, 고려한 옵션, 선택 이유, 장기적인 영향을 설명하세요.

Examples

• ❌ Vague: “Led architecture discussions”
  ✅ Clear: “Proposed and championed migrating our monolithic API to a microservices architecture after identifying scalability bottlenecks. Led technical design discussions, evaluated trade‑offs, and built consensus across four engineering teams. The migration is now underway and will enable us to scale to 10× current traffic.”

• ❌ Vague: “Refactored legacy code”
  ✅ Clear: “Refactored our authentication system to eliminate a 3‑year‑old legacy codebase that was blocking feature development. This unblocked five engineers who were previously spending 30 % of their time working around limitations in the old system. New auth features that previously took weeks now take days.”

Pro tip: Architecture decisions often happen in RFCs, design docs, or Slack threads. Save these artifacts—they’re evidence of your technical judgment and leadership.

4. 프로세스 개선 (CI/CD, 도구, 자동화)

What it is: Improving CI/CD pipelines, dev tooling, testing infrastructure, deployment processes, reducing build times, automating manual work.
What it is: CI/CD 파이프라인, 개발 도구, 테스트 인프라, 배포 프로세스 개선, 빌드 시간 단축, 수동 작업 자동화 등.

Why it matters: Process improvements multiply everyone’s productivity. A 10 % efficiency gain across a 20‑person team is massive.
Why it matters: 프로세스 개선은 전체 생산성을 크게 높입니다. 20명 팀에서 10 % 효율성 향상은 엄청납니다.

How to document it:

• Quantify time saved or problems eliminated.
• Show the multiplier effect across the team.

How to document it:

• 절감된 시간이나 해결된 문제를 수치화하세요.
• 팀 전체에 미친 곱셈 효과를 보여주세요.

Examples

• ❌ Vague: “Improved CI/CD pipeline”
  ✅ Clear: “Reduced CI build times from 25 minutes to 8 minutes by parallelizing test suites and optimizing Docker layer caching. This saves every engineer ~1 hour per day in context switching and enables faster iteration. Across a 15‑person team, this recovers ~300 engineering hours per month.”

• ❌ Vague: “Automated deployment process”
  ✅ Clear: “Built automated deployment tooling that replaced a 30‑minute manual process with a one‑click deploy. This eliminated deployment errors that were causing 1–2 production incidents per month and freed up ~10 hours of engineering time per week.”

Pro tip: Before/after metrics are gold. Measure time saved, error rates reduced, or manual steps eliminated. BragDoc can help you track these automatically.

5. 신뢰성, 온‑콜, 그리고 인시던트 관리

What it is: Debugging production issues, on‑call rotations, monitoring and alerting, postmortems, proactive reliability improvements.
What it is: 프로덕션 이슈 디버깅, 온‑콜 순번, 모니터링·알림, 사후 분석, 사전 신뢰성 개선 등.

Why it matters: Keeping systems running is often invisible until something breaks. Reliability work prevents future fires.
Why it matters: 시스템 가동을 유지하는 일은 문제가 발생하기 전까지는 눈에 보이지 않지만, 신뢰성 작업은 향후 사고를 예방합니다.

How to document it:

• Focus on severity, speed of resolution, and preventative measures you implemented.

How to document it:

• 심각도, 해결 속도, 구현한 예방 조치에 초점을 맞추세요.

Examples

• ❌ Vague: “Fixed production issues”
  ✅ Clear: “Diagnosed and resolved a critical database deadlock that was causing 15‑minute outages every few days. Root cause was a race condition under high load; I identified it within 2 hours using query logs and APM traces. Implemented connection‑pooling changes that eliminated the issue entirely. No recurrence in 3 months.”

• ❌ Vague: “Participated in on‑call rotation”
  ✅ Clear: “Covered on‑call rotation for 6 weeks, responding to 12 incidents with an average resolution time of 45 minutes (team average is 90 minutes). After noticing repeated alerts for the same issue, I proactively fixed the underlying problem, reducing alerts by 40 % for the entire team.”

Pro tip: Keep a log of significant incidents you resolved. Note the business impact (users affected, downtime, revenue impact) and how you prevented future occurrences.

6. 교차 기능 협업

What it is: Working with product, design, sales, customer success, or leadership to solve problems, unblock projects, or improve processes.
What it is: 제품, 디자인, 영업, 고객 성공, 리더십 등과 협력해 문제를 해결하고, 프로젝트를 차단 해제하며, 프로세스를 개선하는 활동.

Why it matters: Senior developers bridge technical and business contexts. Your ability to collaborate across functions becomes increasingly important as you grow.
Why it matters: 시니어 개발자는 기술과 비즈니스 사이를 연결합니다. 성장함에 따라 다양한 부서와 협업하는 능력이 점점 더 중요해집니다.

How to document it:

• Explain the business problem, how you contributed, and the outcome.
• Make your role clear without taking sole credit.

How to document it:

• 비즈니스 문제, 자신의 기여 내용, 결과를 설명하세요.
• 자신의 역할을 명확히 하되, 전적인 공로를 주장하지는 마세요.

Examples

• ❌ Vague: “Worked with product team”
  ✅ Clear: “Partnered with product and design to redesign our notification system after customer feedback showed users were missing critical updates. Led technical feasibility discussions, prototyped three different approaches, and implemented the solution. User engagement with notifications increased 45 %, and support tickets about missed notifications dropped 60 %.”

• ❌ Vague: “Helped sales team with technical questions”
  ✅ Clear: “Supported eight enterprise sales deals by joining discovery calls, answering technical feasibility questions, and providing proof‑of‑concept demos. My contributions helped close $2.3 M in new ARR and reduced the sales cycle by two weeks per deal.”
