# Diego Cárdenas

> Sr FullStack Engineer | PHP (Laravel), Java (Spring), React (Next.js) | Plataforms ISP/FTTH y ERP. Hands-on Software Architect focused on Laravel, React/TypeScript, CRM/ERP platforms, ISP automation, and systems integration.

Canonical profile: https://www.5diego.dev/
Location: Venezuela, UTC-4
Work preference: International remote
Languages: Spanish (native), English (self-assessed B2 for technical work)
Laravel: used daily; adopted in 2013 after prior Yii experience; versions 8–13 used in recent projects.

## Primary professional history

- WISPLAY Connections C.A., January 2020 to November 2025: Senior Full-Stack Developer / ISP Systems Engineer.
- VASQGROUP IT C.A., January 2026 to August 2026: Software Architect / Senior Full-Stack Engineer.
- These roles form one continuous ISP career path under the same owner. Qeza at VASQGROUP evolved the CRM/ERP and network-operations knowledge developed at WISPLAY.

## Verified areas of work

- Laravel CRM/ERP systems for ISP operations.
- Customer, contract, billing, collections, support, and cash-register workflows.
- Wispro data synchronization.
- MikroTik RouterOS REST API: provisioning, queues, VLAN, suspension, and reactivation.
- FTTH GIS, V-SOL OLT, PPPoE, telemetry, and subscriber portal APIs.
- LEsys fiscal-document integration.
- WhatsApp workflows with Hola Suite and Baileys.
- Real-time interfaces with Laravel Reverb.
- LLM integrations with DeepSeek, OpenAI, and Anthropic-compatible providers.

## AI-first engineering workflow

- Measure and document the problem before generating code.
- Write canonical Markdown specs covering architecture, data, failure modes, scope, and acceptance criteria.
- Use AGENTS.md for global constraints where applicable.
- Use compact Cursor Rules selected by file glob.
- Use separate versioned Skills for architecture, database schema, Redis, testing, forms, and UI.
- Delegate implementation by layer and verify the result against the spec.
- Use Unit tests for isolated logic, Feature/API tests for business rules and persistence, and Playwright only for critical browser journeys once the UI is connected.

Example: Qeza WAN traffic was designed from a measured 288 MB footprint where traffic represented 86% of the database. The documented architecture defined one multi-interface REST call per server, raw persistence every five seconds, Reverb updates every second, and retention rollups before implementation.

## Parallel contracts and products

- RapiKargas, March 2023 to July 2026: freelance logistics-platform project, currently paused.
