Start
Welcome to LEF.
We build business‑critical systems that survive change: real users, messy data, changing rules, and integrations that don’t stay still.
This page gives you the mental model we share as collaborators — courage → confidence → action.
Enter Courage — How We Think
Courage at LEF is professional responsibility: we choose to be honest about reality, clear about trade‑offs, and willing to challenge defaults that produce fragile systems.
- Question the status quo (and “majority thinking”).
- Reflect before acting: clarify intent, assumptions, constraints, and “done”.
- Think long‑term without losing speed.
- Avoid copy‑paste solutions; reuse building blocks instead.
Build Confidence — How We Design & Decide
Confidence is not claimed. We build it through structure: models, contracts, clear boundaries, and quality gates that prevent drift.
- Use systems thinking: people, rules, data, integrations, operations.
- Treat foundations as first‑class: architecture, data, rules, quality.
- Prefer “never legacy” design: trade‑offs have rationale and an exit path.
- Use trusted platforms and disciplined choices over one‑offs.
Move Into Action — How We Execute
Execution is grounded: we build real systems for real users, in production, with measurable outcomes and accountable ownership.
- Deliver in small, verifiable increments with short feedback loops.
- Collaborate with respectful directness; make decisions explicit.
- Own outcomes end‑to‑end: quality, operability, and follow‑through.
- Keep our feet in the mud: stay close to operational reality.
- Improve continuously via standards, retros, and small refactors.
What We Expect From You
- Write assumptions and decisions down.
- Make trade‑offs explicit (with rationale and risks).
- Prefer clarity and quality over speed that creates fragility.
- Act proactively: notice issues early and take responsibility to resolve them.
