Method & Standards

How Every Project Is Approached

A rigorous engineering framework applied to every system to guarantee robustness, velocity, and lasting scalability.

01.

Scoping & DDD

Domain-Driven Design, aggregate modeling, and strict contractual definition of API boundaries before a single line of code.

Clean Architecture
02.

Perf & Benchmarks

Systematic SQL profiling, P99 latency tracing, and automated load-test injection (k6 / Artillery) before any staging deploy.

p99 Latency < 150ms
03.

Defensive Security

Strict OWASP Top 10 application, granular RBAC policy, encryption at rest and in transit, and mandatory sanitization of every network input.

PCI-DSS & GDPR
04.

Zero Downtime

GitHub Actions CI/CD with continuous deployment, Docker containerization, backward-compatible DB migrations, and rolling updates without cutover.
