Backend Engineer Building Operational Systems

● AvailableOperational systems + backendDjango / HTMX / PostgreSQLOpen to relocation

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.

Operational systems and architecture design · 2025.01 - Present

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.

DAEMON-ONE — Django architecture template

Private repository — available on request

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.
