Note: Technology evolves faster than certification cycles. I focus on shipping working solutions rather than maintaining certificates. translatedBy: “단풍이 (Danpoongi) - z.ai Translation Agent” translationNotice: “이 글은 단풍이(Danpoongi)가 z.ai의 3단계 번역 에이전트를 사용하여 번역했습니다. 원문은 영어로 작성되었습니다.” translationAgent: “https://z.ai”

안녕하십니오, 알렉스 스페조카입니다.

십 년이 넘는 경험을 바탕으로 확장 가능한 시스템을 구축해왔으며, 인프라부터 사용자 인터페이스에 이르기까지 완전한 기술 솔루션을 설계합니다. 저는 레거시 시스템을 현대적인 아키텍처로 전환하고, AI 기반 애플리케이션을 구현하며, 전체 스택에서 복잡한 기술적 문제를 해결하는 데 전문성을 가지고 있습니다.

현재 프리랜서로 활동 중입니다. 만약 귀사에 ‘거점 해커’가 필요하시다면, 대화해봅시다.

핵심 철학

저의 디자인 철학은 초기능주의(hyper-functionalism)에 기반합니다: 임기를 초과하는 시스템을 구축하고, 현재의 필요를 넘어 확장 가능하며, 향후 팀이 유지보수할 수 있는 시스템을 만드는 것입니다. 모든 아키텍처 결정은 탄력성, 관찰 가능성, 개발자 경험을 최우선으로 합니다.

발표 및 리더십

컨퍼런스 발표:

  • NCRAC 2023 - “노 코드 라디오: 저 코드 도구가 비영리 환경에서 어떻게 활용될 수 있는가”
  • 사운드오프 서밋 2024 - “라벨 자동화: 간단한 도구가 생산성을 높이고 비용을 줄이는 방법”

기술 리더십:

  • 공식 코드 리뷰 프로세스를 도입하여 버그 발생률을 60% 감소
  • 문서화 표준을 만들어 개발자 온보딩 시간을 주에서 일로 단축
  • 2-10명 개발자 팀의 기술적 의사결정을 주도
