Hi, I'm Daniel 👋

I find where people get stuck. Then I build the thing that removes it.

Portfolio LinkedIn Based in Hungary


I build software because it's one of the most direct paths from an idea to a working product.

Web applications, AI integrations, and the automation that holds them together, personalized around whoever's actually using them, not built from a template. Self-taught, which means every project here was both the lesson and the thing that shipped.

By day I work in desktop and endpoint support. Different surface, same instinct: find where someone is stuck, and remove it.

So that's how this page is organized: each project is filed like a support ticket, by the problem it removes.


🎫 Resolved tickets

ScreenPrompt

Ticket #001  ·  The problem: looking away at your notes during a call or recording makes you seem unprepared.

Status: resolved

Your notes, scripts, and reminders: visible to you, invisible to everyone else.

A transparent, always-on-top overlay for Windows. You can read it; screen shares and recordings can't. It's excluded from capture in OBS, Zoom, Teams, and Windows' own Snipping Tool, so your notes stay on screen during a call or stream without anyone seeing them. Runs 100% locally, no telemetry.

The first version was written in Python; the current one runs on Tauri 2.

Perch

Ticket #002  ·  The problem: a Windows snip only lands on the clipboard, so it can be pasted but not dragged into an upload box.

Status: resolved

A temporary screenshot shelf for Windows. Snips land, perch for a while, then fly off.

Win+Shift+S only puts a screenshot on the clipboard, so you can paste it but you can't drag it. Perch catches every snip, shelves it as a card at the edge of your screen, and lets you drag one or a whole batch into any app or upload box as real PNG files. Snips expire on their own. No network calls, no telemetry.

🕐 LinkedIn Post Date Extractor

Ticket #003  ·  The problem: LinkedIn only shows relative times like "3d ago", never the exact moment a post went up.

Status: resolved

A Chrome extension that turns LinkedIn's vague "2h ago" into a precise timestamp, decoded straight from the post ID. Useful when the order of events actually matters.
