Jacob Slutzky

Product Lead @ FoodFluence AI
Software Engineer @ Wayfair

February 10, 2026 · Jacob was senior to Youngjun but didn’t manage Youngjun directly

I’ve had the privilege of working with Youngjun and would strongly recommend him as a teammate. He brings relentless drive and grit to shipping features quickly and never shies away from a challenge. Jun consistently executes with speed, often taking on additional work and proactively expanding his scope to help his team move faster.

He is highly collaborative with a strong growth mindset and is especially knowledgeable about AI, thoughtfully leveraging it to improve his productivity, code quality, and problem-solving. Beyond being a skilled developer, he deeply cares about the product he’s building and is committed to delivering the best possible user experience.

Branson Packard

CEO, Co-Founder @ FoodFluence AI
January 21, 2026 · Branson managed Youngjun directly

Youngjun is one of the most driven and resilient engineers I’ve had the pleasure of working with. At our early-stage tech startup, he consistently demonstrated grit, ownership, and a true builder’s mindset. When something needed to get done, Youngjun did not wait for direction or ideal conditions, he simply took responsibility and executed.

There were countless times he was working late into the night or up early in the morning to ship a feature, fix a bug, or unblock the team. He approached problems with persistence and focus, and he never shied away from the hard or unglamorous work that startups demand.

It is genuinely rare to find a Gen Z engineer with Youngjun’s level of work ethic, reliability, and commitment to excellence. He would be a huge asset to any team looking for someone who not only has technical ability, but also the discipline and determination to see things through.

Dae Kwang Lee

Senior Software Engineer @ Samsung SDS
August 5, 2025 · Dae Kwang was Youngjun’s mentor

During his internship, he demonstrated strong responsibility, creativity, and a genuine passion for AI. He contributed to an AI agent project, where he thoughtfully designed and implemented the agent’s memory. His ability to structure complex ideas in writing and his respectful, collaborative attitude stood out. I’m confident he’ll grow into an exceptional AI engineer.
