# Jorge Alonso > I'm a developer and sysadmin at EnfoquesTIC in Galicia, Spain. I build Rust and Tauri desktop apps, Go and TypeScript backends, and MCP servers for SAP and SQL. My work also includes IoT, Linux hosting and hardening. [Website](https://jorgealonsodev.xdev.es/) ## I build software and work with the systems that run it. At EnfoquesTIC, I work as a developer and sysadmin. I build firmware and apps for connected devices and develop backend services. I also manage Linux servers. I started most of my public repositories as tools I needed myself. Some have since become products, including PlexusTerm. ## What I work on ### IoT & mobile - Go services and a Next.js portal for an IoT platform designed for wearables - Wear OS app that handles calls and sends health telemetry over MQTT - ESP32 firmware and a Flutter app talking to each other over BLE ### Backend & AI - MCP servers for AI agents to query SAP Business One on HANA, SQL Server and MySQL - AI agent workflows in n8n - Python service that unfolds sheet-metal parts from STEP files with OpenCascade and the DIN 6935 K factor ### Linux & hosting - Plesk hosting servers, Nginx and Apache - DNS and mail: SPF, DMARC, relay through AWS SES - Docker and Portainer, Prometheus and Grafana, Zitadel ### Security - Server audits and pentests with Strix - Cleanup of compromised WordPress and PrestaShop sites - Linux hardening against CIS Benchmarks with Vallumix ## Selected work ### vallumix Linux hardening engine Applies CIS Benchmark controls idempotently, writes auditable reports and supports safe rollback.
