Full-stack product developer · China · remote
I build useful software that reaches production.
AI applications, multilingual products, learning platforms, and complex client systems. I use Codex to accelerate implementation, while keeping architecture, business rules, review, testing, and release accountable to a human.

The delivery contract
Codex accelerates the work. Review still decides what ships.
-
01
Define the boundary
Acceptance criteria, roles, data, edge cases, and a first milestone that can be demonstrated.
-
02
Inspect the system
Trace the existing pages, APIs, schemas, call chains, and deployment constraints before changing code.
-
03
Delegate bounded slices
Use Codex for navigation, repetitive edits, implementation drafts, and test scaffolding — one verifiable slice at a time.
-
04
Review and prove
Check authorization, money, inventory, state, and failure paths; verify with tests, logs, SQL, deployment, and a working demo.
About
I care about the unglamorous parts that make a product work.
I am Le Li, a full-stack developer with approximately five years of experience across Java, TypeScript, Web, and mini-program delivery. My strongest work sits where product behavior meets engineering constraints: permissions, state transitions, amounts, inventory, migration, failure recovery, and release verification.
I work remotely with clear written requirements, short feedback loops, working demos, and handoff notes that let the next developer continue without reverse-engineering the project.
