Engineering Playbook

How 2Logics designs, builds, and operates software that lasts.

A living reference for clients, partners, and engineers—not marketing slogans.

01

Architecture Principles

Boundaries first. Contracts explicit. Failure modes designed early.

02

Security by Design

Threat modelling precedes features. Least privilege is structural.

03

Accessibility

Inclusive interfaces expand reach and reduce institutional risk.

04

Cloud Strategy

IaC, reproducible environments, and cost-aware capacity.

05

Testing

Automated critical paths make frequent release safe.

06

Performance

Budgets are acceptance criteria—not aspirational slides.

07

Maintainability

Typed systems and living docs survive staff changes.

08

Documentation

ADRs, runbooks, and handoff packs for audits and operators.

09

CI/CD

Release trains with quality gates and reversible deploys.

10

Monitoring

You cannot operate what you cannot see.

11

Disaster Recovery

Backups and restore drills before the first incident.

12

Governance

Architecture, security, QA, and executive reporting in sync.
