ROBERT

VAN 'T HUL

Systems-focused developer from Kampen, NL. I build across backend, networking, geospatial frontends, and hardware — and I prefer understanding the plumbing before writing a single line of code.

Not Just A
"Web Dev"

I'm a systems-focused full-stack developer with a strong interest in networking, infrastructure, AI integration, satellite communications, and hardware-level independence. I don't just deploy software — I want to understand every layer of the stack.

Currently working as a Junior Software Developer at De Boer Marine in Urk, building production satellite monitoring pipelines for maritime fleets. Simultaneously in my first year of HBO ICT — Data Science & AI.

Most developers argue about frameworks. I think about architecture before implementation, prefer building over buying, and experiment widely instead of staying in one niche. That combination is dangerous — in the best way.

Tech Arsenal

Stacking competencies across backend, networking, geospatial, hardware. Not dabbling — building.

🖥️
BACKEND & INFRA
Production PHP (Joomla-heavy), complex JOIN queries, custom monitoring portals, cron job automation and server-side data pipelines. Infrastructure efficiency is a core principle.
PHPSQLJoomlaCron JobsREST APIs
🛰️
SATCOM & MONITORING
Working with VSAT and Starlink APIs in maritime production. Processing iDirect Pulse telemetry, LibreNMS integration, and building dashboards for satellite network health.

🤖
AI INTEGRATION
Designing AI pipelines that separate compute loads — portal writes to DB, AI server reads and processes on a NAT-isolated machine, results feed back. Systems thinking applied to ML.

🗺️
GEOSPATIAL FRONTEND
Custom Leaflet controls with great-circle calculations, satellite beam polygon distance math, antimeridian handling, and live vessel tracking inputs for heading and speed.

NETWORKING & SECURITY
DNS, DNSSEC, Cloudflare config, Let's Encrypt / Certbot, WHOIS infrastructure analysis. Building DIY TOTP generators with radio time sync — zero dependency on external services.

Selected Work

01
// MARITIME SATCOM · De Boer Marine
AI Satellite Monitoring Portal
Production monitoring pipeline for maritime VSAT and Starlink fleets. VSAT data ingested every 5 min, Starlink every 15 sec. AI analysis runs on a separate NAT-isolated server to prevent portal performance degradation.
