Welcome to SYNTAX. This isn’t a textbook—it’s a workspace. I share Simple Yet Necessary Tips And eXperiments in technology, covering everything from the code snippets you need today to the deep-dive projects you might try tomorrow.

👋 Hi, I’m Alfredo Sanchez

I’m an IT professional based in the Philippines, working extensively in systems, networks, software, and shipboard IoT technology. I enjoy building practical systems that solve real operational problems — from ERP modules to GPS tracking, CCTV integrations, solar-powered vessel systems, and various in-house applications.

My focus areas include:

• 🚢 Maritime technology – GPS, AIS, Starlink integration, shipboard IoT
• 🖥️ Systems & Network Administration – firewalls, servers, structured networks
• 🛠️ Software Development – ERP, REST APIs, monitoring dashboards
• ⚡ Solar & Power Systems – inverters, battery setups, shipwide solar projects
• 📡 Connectivity Solutions – Starlink deployment for vessels & remote sites

🏢 What I Do

I handle technical operations, infrastructure, and system development for our company. This includes:

• Designing and maintaining ship-to-shore communication systems
• Overseeing hardware, networking, and system verifications
• Building and maintaining in-house software and ERP modules
• Ensuring our fleets stay connected and monitored across the Philippines
• Managing deployments like servers, CCTVs, solar power systems, and kiosks

I also enjoy researching new tools, optimizing workflows, and integrating emerging tech to improve operational efficiency.

🧰 Technologies I Work With

• Backend: PHP (CodeIgniter), Node/Express
• Frontend: React, Next.js
• Databases: MySQL, Redis, PostgreSQL
• Network: Mikrotik, Ubiquiti, Ruijie, SUS, VPNs, VLANs
• IoT: ESP32, GPS, AIS, custom sensors
• Power: Solar panels, MPPTs, inverters, LiFePO4 & deep cycle batteries
