binbin

Full-stack developer, still a student.

Since June 2025 I've been working on an AI nail platform and a multi-tenant HRIS at Manience Inc. Outside work, I independently built and now run two systems in daily use at NKUST. This site records how these systems were designed — the trade-offs made and the lessons learned — in the form of engineering notes.

BACKEND · SYSTEM DESIGN · AI INTEGRATION

Simplified view: the microservice topology I work on day to day — every node is a real service.

01 / SELECTED PROJECTS

Each system is documented in the same format: problem, constraints, architecture, challenges, results.

Multi-tenant SaaS HRISFULL STACK

A multi-tenant HR platform — attendance, scheduling, payroll, approvals, recruiting — across 36 modules; currently in acceptance and remediation.

04 / PRINCIPLES

A few principles these projects kept proving true.

Measure first. Optimize second.

Boundaries matter more than components.

AI amplifies engineering — it does not replace it.
