Senior software engineer driving cloud modernization and scalable systems.
South KoreaWhat I'm looking for
I am a senior software engineer with a track record of taking initiatives from concept to production; I spearheaded a full-scale implementation of a cloud-based document processing system, replacing legacy on-premise infrastructure and achieving a 35% reduction in operational costs.
I evolved an internal monitoring tool into a full-featured, integrated operations suite, freeing around 15 hours per week across departments and improving incident response time by 30%. I also developed internal tooling that reduced average troubleshooting time of operational incidents by 50% and improved system observability.
I focus on building high-velocity, quality-focused teams by codifying technical standards, mentoring junior developers, and formalising workflows based on automated testing, CI/CD, and learning-focused code reviews—efforts that increased team velocity by 3x.
I co-founded Manager Kim’s Korean and lead its technical development while conducting user research to validate core features; I hold a Full-Stack Web Development credential from OpenClassrooms and enjoy balancing product thinking with hands-on engineering.
