Wonsub Song (Tony)
Backend Engineer Building Operational Systems
Summary
I identify repeated manual work and operational friction, then turn it into stable systems teams can use every day. My background spans Sports Science and programming, which trained me to ramp quickly in unfamiliar domains and structure workflows and constraints before building.
With LawNGood POC, I automated a legal-news monitoring workflow. With ClubKebi, I turned sports-academy operations based on paper and spreadsheets into a live web service. I use DAEMON-ONE principles to build domain boundaries that remain maintainable as operational work grows, and take responsibility through deployment and operation.
Communication & Thinking
Asian Parliamentary Debate — University-level champion
University-level Asian Parliamentary Debate champion. Repeatedly trained to analyze unfamiliar topics and structure persuasive arguments within 15-minute preparation windows across economics, policy, healthcare, and technology. WUDC participant. Founded SEDA and ESC and led both.
English: Professional working proficiency.
Experience
Backend Engineer — Intern
Automated a LawAndGood workflow in which one employee monitored and classified up to 60 articles per day against internal guidelines. In a two-person team, designed and implemented the operating pipeline from collection and parsing through AI classification, grouping, and review.
Solo · Backend Engineer / Product Builder
After observing the burden of paper-and-spreadsheet operations at a sports academy, I built and now operate ClubKebi in ongoing dialogue with its operator. I designed and applied DAEMON-ONE principles to keep growing operational workflows maintainable.
Architecture
DAEMON-ONE — Django architecture template
DAEMON-ONE is a set of principles for preventing complex field operations from becoming entangled as features grow. It turns repeated work into maintainable systems by preserving the following boundaries:
- Modular Monolith over microservices — single deployable unit, domain boundaries enforced via
interface.py. - HTMX + SSR over React — server-driven state, zero JS build step, LCP-first rendering.
- Vertical Slicing — logic, template, and style colocated per feature. Delete a folder = feature gone cleanly.
Selected Projects
ClubKebi
A live operations Web SaaS that turns a sports academy's paper-and-spreadsheet workflows into student, attendance, makeup-class, and revenue management.
LawNGood POC
A legal-news operations POC that automated an employee workflow of monitoring and classifying up to 60 articles per day.
