N.01 OWN PRODUCT
CORESYNTH.IO
A hosting platform I'm building to make server management simpler. Provisioning, automation, an AI agent and operational tooling in one place.
WEBSITES, SYSTEMS. AND SOLID. BACKEND_
I'm Filip Džudža — a developer from Sychrov. I build websites, internal tools and hosting systems with Next.js, PHP and TypeScript. I like practical work: a fast website, a stable server, automation that saves time and code that is easy to maintain.

PRACTICAL DEV.
I don't sell buzzwords. I take a problem, split it into smaller parts and build something people can actually use and maintain. I work across frontend, backend and server operations — so I care about how it looks, how it works and how it runs.
WEBS & APPS
Next.js, Astro, React, PHP. Fast presentation sites, admin panels, internal tools and customer-facing systems.
SERVERS & HOSTING
Linux, Nginx, Docker, Proxmox, databases and automation. Things that should run reliably without unnecessary drama.
AUTOMOTIVE
Besides web work, I also do programming around automotive. It's a technical overlap, not the main face of this portfolio.

WEB DEVELOPMENT
I build websites and applications with Next.js, Astro, React and PHP. I like clean interfaces, fast loading and a backend that still makes sense a month later.
N.03 SERVERS / TOOLS
AUTOMATION
If something can be simplified with a script, cron job, API or internal panel, it's usually worth doing. Time saved is the best feature.
PRICING.

→ DISCUSS SCOPE PRINCIPLES.
01
UNDERSTAND FIRST
Before writing code, I want to know what the result should actually solve. A good website is not just pretty — it helps people or work.
02
SIMPLE AND HONEST
I don't add technology just because it's trendy. If PHP and Nginx are enough, they're enough. If Next.js makes sense, I use Next.js.
03
THINK ABOUT OPERATIONS
A website doesn't end at deploy. I care about performance, backups, logs, updates, hosting and being able to find issues quickly.
04
NORMAL COMMUNICATION
No corporate fog. I'll tell you what makes sense, what is unnecessary and what I would do first in your place.
TESTIMONIALS.
Filip brought our bookings, e-shop and client accounts into one system that finally makes sense. We save a ton of time on admin and clients book online themselves. Straight talk, no fluff.
I needed a website, service bookings and an e-shop in one place. Filip built it so I can run it alongside my work in the workshop — fast, stable, and whenever something needs tweaking it's handled right away.
