About
I completed a full spectrum accounting education from my bachelor's, master's, CPA to working at a big accounting firm. This was all in a half-hearted attempt to rebel against my parent's wanting me to be a doctor/lawyer. In the end, I lost years of doing the work I actually love: using factual data to make important decisions for all things and making that accessible through open source, not just accounting. I wish I had mentors that empowered me to run towards problems that excite me rather than run away from one career to another. I hope to be that mentor I wish I had. Whether it's career or specific tech advice related to my skills, I've lived and breathed the problems you're facing now.
I'm excited to see you step closer to becoming someone you're proud of.
What mentees say
5 out of 5 stars
Sung was a fantastic mentor! I started working with Sung about 3 months ago. At that time, I was a data analyst at a large company and my job duties were a lot of data pipelines, dashboards, SQL, python, etc. I wanted to work on more interesting work beyond just data analyst work building dashboards. Sung and I worked on a plan for what I wanted my role to look like, what kind of company and industry I ideally wanted to join, and what I wanted my career to get to. Along the way we'd have calls where he would test my understanding of things, whether that be dbt, SQL, or python and would tell me how a hiring manager would understand my answer. We'd also go over what red flags to look for in job postings to make sure I wasn't joining a team/company that would not grow my skills. All in all, 3 months later, I'm happy to say I landed a role that I wanted at the company I wanted, having a 60k salary increase from my previous role!

I'm a data operation/analyst at a small HR/payroll company with no senior engineer to learn from, and I'd felt stuck for a 2-3 years. I picked Sung because he switched careers himself. We shared similar but not identical career pathways. He got it right away. In our first call he sized me up honestly as an "Advanced Beginner", then built the plan around my actual job (implement dbt + Airflow properly in prod and use that as the interview story) instead of a generic course list. He also told me to stop grinding LeetCode and focus on SQL, Airflow and data modeling, which saved me a lot of wasted hours. Reviewed my resume the next day, blunt about which tools and job postings are worth your time, and genuinely responsive async. If you're an analyst trying to move into real data engineering, he's a great pick for sure.

Good job, 30 minutes call is a bit shorter for me to get proper help.
