https://brunch.co.kr/@@2c66 개발자는 제 꿈이 아니었습니다. 꿈이 아닌 길을 걸으며 살아남고자 고군분투하는 이야기를 담았습니다. ko Mon, 04 May 2026 09:43:32 GMT Kakao Brunch //img1.kakaocdn.net/thumb/C100x100/?fname=http%3A%2F%2Ft1.daumcdn.net%2Fbrunch%2Fservice%2Fuser%2F2c66%2Fimage%2Fks-FWwoC_GS7u1Eb3-mJ4sXTOBI.png https://brunch.co.kr/@@2c66 100 100 https://brunch.co.kr/@@2c66/432 최근 Spring MVC 프레임 워크에서 Reactor Core를 사용한 코드를 보게 되었다. 새로운 기술을 도입하는 것은 좋으나 원래의 목적에 맞게 잘 사용되고 있는지가 의문이었고 코드 리뷰시 어떤 목적과 의도로 사용된 것인지 확인하고자 하였으나 깊게 의논할 겨를 없이 코드는 머지가 되고 말았다. 코드를 작성한 당사자의 의도는 성능 향상을 위함이 Sun, 19 Oct 2025 03:29:14 GMT youngstone https://brunch.co.kr/@@2c66/432 https://brunch.co.kr/@@2c66/417 After we opened the early access program, our team was inundated with feedback we didn’t anticipate. 얼리 액세스 프로그램을 열자마자, 예상을 뛰어넘는 피드백이 밀려들어 감당할 수 없었어요. Sat, 19 Jul 2025 00:00:14 GMT youngstone https://brunch.co.kr/@@2c66/417 https://brunch.co.kr/@@2c66/419 After the feature launch, we got a deluge of support tickets we weren’t ready for. 기능을 출시하고 나니, 감당 못 할 정도로 고객 문의가 쏟아졌어요. Fri, 18 Jul 2025 00:00:24 GMT youngstone https://brunch.co.kr/@@2c66/419 https://brunch.co.kr/@@2c66/415 We thought AI would save us time, but all it did was generate AI sludge that we had to clean up manually. AI가 시간을 절약해줄 줄 알았는데, 결국 사람이 직접 치워야 할 쓸모없는 찌꺼기만 잔뜩 만들어냈어요. Thu, 17 Jul 2025 00:00:19 GMT youngstone https://brunch.co.kr/@@2c66/415 https://brunch.co.kr/@@2c66/408 Instead of helping, he just kept one-upping everyone with his “better” solutions. 도와주기보다는 자기 솔루션이 더 낫다며 괜히 잘난 척만 했어요. Fri, 11 Jul 2025 23:00:14 GMT youngstone https://brunch.co.kr/@@2c66/408 https://brunch.co.kr/@@2c66/409 He kept interrupting the demo and upstaging everyone else on the team. 그는 계속 데모를 끊고 팀원들의 빛을 다 가로채 버렸어요. Thu, 10 Jul 2025 22:09:28 GMT youngstone https://brunch.co.kr/@@2c66/409 https://brunch.co.kr/@@2c66/410 We missed the release date, but I’d put this down to the fact that the scope kept changing. 출시일을 놓친 건 범위가 계속 바뀐 탓이라고 봐야겠죠. Wed, 09 Jul 2025 23:40:17 GMT youngstone https://brunch.co.kr/@@2c66/410 https://brunch.co.kr/@@2c66/404 When the production server went down, I almost lost my composure — but staying calm helped us fix it faster. 운영 서버가 다운됐을 때 거의 멘탈이 나갈 뻔했지만, 침착함을 유지해서 더 빨리 해결할 수 있었어요. Sun, 06 Jul 2025 00:00:12 GMT youngstone https://brunch.co.kr/@@2c66/404 https://brunch.co.kr/@@2c66/403 The live demo crashed halfway through — it was such an embarrassing ordeal for the whole team. 라이브 데모가 중간에 멈춰버려서 팀 모두에게 정말 창피하고 곤란한 경험이었어요. Sat, 05 Jul 2025 00:00:17 GMT youngstone https://brunch.co.kr/@@2c66/403 https://brunch.co.kr/@@2c66/365 Don’t worry — meeting the launch date is still within our reach if we stick to the plan. 걱정 마세요 — 계획만 잘 지키면 출시일 맞추는 건 아직 충분히 가능합니다. Thu, 03 Jul 2025 22:50:21 GMT youngstone https://brunch.co.kr/@@2c66/365 https://brunch.co.kr/@@2c66/392 The team’s overall performance was dragged down by poor communication between frontend and backend engineers. 프론트엔드와 백엔드 엔지니어 간의 원활하지 못한 소통 때문에 팀 전체의 퍼포먼스가 부정적인 영향을 받았습니다. Thu, 26 Jun 2025 00:00:17 GMT youngstone https://brunch.co.kr/@@2c66/392 https://brunch.co.kr/@@2c66/397 He stretched the truth during the sprint demo to make it seem like the feature was fully completed. 그는 스프린트 데모 중 기능이 완전히 완성된 것처럼 보이게 하려고 사실을 좀 과장했어요. Sun, 22 Jun 2025 23:00:11 GMT youngstone https://brunch.co.kr/@@2c66/397 https://brunch.co.kr/@@2c66/400 When the deployment failed, the manager threw the junior developer under the bus to avoid taking the blame. 배포에 실패하자, 매니저는 책임을 피하려고 주니어 개발자에게 책임을 떠넘겼어요. Sat, 21 Jun 2025 23:00:05 GMT youngstone https://brunch.co.kr/@@2c66/400 https://brunch.co.kr/@@2c66/398 The app’s performance after the latest optimization was off the chart — response time dropped by over 80%! 최근 최적화 이후 앱 성능이 엄청났어요 — 응답 시간이 80% 이상 줄었거든요! Fri, 20 Jun 2025 23:00:07 GMT youngstone https://brunch.co.kr/@@2c66/398 https://brunch.co.kr/@@2c66/399 You missed a small bug in the code review, but don’t beat yourself up — everyone makes mistakes sometimes. 코드 리뷰에서 작은 버그를 놓쳤지만, 자책하지 마세요 — 누구나 실수할 수 있어요. Thu, 19 Jun 2025 23:00:20 GMT youngstone https://brunch.co.kr/@@2c66/399 https://brunch.co.kr/@@2c66/363 If you apply yourself to understanding system design principles, you'll become a much stronger engineer. 시스템 설계 원칙을 이해하는 데 전념하면, 훨씬 더 유능한 엔지니어가 될 거예요. Wed, 18 Jun 2025 13:32:15 GMT youngstone https://brunch.co.kr/@@2c66/363 https://brunch.co.kr/@@2c66/362 During the postmortem, they tried to gloss over the fact that the outage was preventable. 포스트모템 회의에서, 그 장애가 예방 가능했다는 점은 대충 얼버무리려고 했어요. Sun, 01 Jun 2025 03:26:30 GMT youngstone https://brunch.co.kr/@@2c66/362 https://brunch.co.kr/@@2c66/334 To handle thousands of requests per second, we had to rethink our design and exploit concurrency. 초당 수천 건의 요청을 처리하려면, 설계를 다시 생각하고 동시성을 적극 활용해야 했어요. Sun, 01 Jun 2025 03:24:34 GMT youngstone https://brunch.co.kr/@@2c66/334 https://brunch.co.kr/@@2c66/364 I don’t know how she did it, but she conjured up a working prototype overnight. 어떻게 했는지는 모르겠지만, 하룻밤 만에 작동하는 프로토타입을 만들어냈어요. Sun, 01 Jun 2025 03:22:50 GMT youngstone https://brunch.co.kr/@@2c66/364 https://brunch.co.kr/@@2c66/367 We were ready to deploy, but a weird bug cropped up during final testing. 배포 준비는 다 됐는데, 마지막 테스트 중에 이상한 버그가 불쑥 생겼어요.
