Jaeil (Brasley) Byun: Shaping Korea’s Career Development Scene with Authentic Thought Leadership
Jaeil (Brasley) Byun is currently a Sales and Marketing Associate at ZEISS Vision Korea. His professional journey began with a distinctive spark during his internship at SAP Korea, where he first started producing content related to CSR, sustainability, and employee engagement. Even at that early stage, Brasley demonstrated not only initiative but a commitment to turning corporate experiences into learning moments for a wider audience.
Beyond his job titles, Byun has consistently positioned himself as a bridge between companies and communities. His career is driven by a personal mission: “to become a shining light for us.” That mantra isn’t just philosophical—it’s visible in the events he has organized, such as a 300-person collaboration with Bayern Munich Youth Academy, and in his public-facing efforts to humanize the work experience in Korea.

Brasley’s content centers on topics often overlooked in traditional Korean corporate culture, such as mental health during job hunting, confidence building, and inclusive networking. He does so in a tone that is both empathetic and courageous—making him a valuable mentor figure to many in the Korean LinkedIn space. His posts are candid, often visual, and provoke honest discussions in the comments.
As a graduate of Hanyang University, he maintains strong academic ties and is passionate about democratizing career opportunities, particularly in education and STEM. His identity is interwoven with the causes he champions, and he isn’t afraid to take up space where it matters—especially on LinkedIn, where he has become one of Korea’s rising thought leaders in the careers and education vertical.
An Influencer Active on LinkedIn

Brasley Byun leverages his growing LinkedIn platform to empower Korean professionals and students through honest, educational, and purpose-driven content.

LinkedIn: Korea’s Morning Mentor with Relatable Corporate Insights

Brasley Byun has built a loyal audience of over 17.8K followers on LinkedIn by turning his professional journey into actionable learning for others. He consistently posts every day at 6PM, establishing a predictable presence that aligns with the start of the Korean workday. His early-morning routine reinforces trust and reflects discipline—traits that resonate with his largely student and junior professional audience. The result is a creator who feels accessible, reliable, and professionally credible.
What makes Brasley’s content stand out is his willingness to expose workplace vulnerability. He discusses real experiences—from fumbling through his first corporate presentation to facing online harassment in networking spaces—with a tone that’s candid but composed. These stories are not curated for perfection; instead, they show process and growth. His audience engages because they see their own struggles reflected with clarity and care.

Visually, Brasley mixes minimal design with high emotional resonance. He uses text-message screenshots, simple illustrations, or in-event photos—not to showcase branding, but to tell human stories. These visuals spark immediate recognition and scrolling pauses, particularly among students navigating similar career stages. Every visual serves the story, never the other way around.
He also responds frequently to comments, turning his posts into micro-communities. His content doesn’t just inform—it invites reflection and sharing, especially around the emotional realities of early career life. Brasley’s influence isn’t built on virality, but repetition, rhythm, and relatability. His presence functions less like an influencer and more like a trusted morning mentor.

Newsletter: SAP Korea STAR Intern Diary

Brasley Byun extends his digital influence through his newsletter, SAP Korea STAR Intern Diary, which has attracted 3.2K followers. The newsletter began as a reflective journal during his internship at SAP Korea, but quickly evolved into a guide for students seeking real-world corporate insights. Unlike typical internship recaps, it offers specific stories, such as learning how to communicate project ideas to senior leadership or adjusting to unexpected feedback loops. Each post is crafted to make professional growth feel less abstract and more achievable.
What makes this newsletter unique is its strategic storytelling approach. Brasley doesn’t just describe what happened—he breaks down how he responded and what others can learn from it. Topics range from navigating imposter syndrome during high-stakes presentations to understanding cross-functional teamwork in a large tech environment. His writing is clear, concise, and personal, which helps maintain authenticity while still delivering structured learning. It's especially effective for Korean readers seeking local, relatable workplace narratives.
The newsletter fills a noticeable content gap in Korea’s education-to-career pipeline. Most career content in the region is either too formal or too vague—Brasley hits the middle ground. He provides insight into the nuances of Korean corporate culture, such as hierarchical communication or silent performance expectations, without alienating younger readers. As someone close in age to his audience, his content feels peer-to-peer rather than top-down, which builds long-term trust.
More than just a personal archive, SAP Korea STAR Intern Diary is becoming an evergreen resource for aspiring professionals. Students can return to older posts and still extract value, thanks to Brasley’s focus on transferable lessons and emotional transparency. In doing so, he has established not only a content format—but a content standard—for future interns looking to share their experience in a meaningful way.
