Cled Ngoy — systems engineer, backend & security.

I design for the failure mode first — architecture, data boundaries, and the security assumptions that hold when something goes wrong. Frontend when it's asked of me. A fictional universe on the side.

About

I'd rather understand a system than just ship it.

I'm a developer who leans hard toward the backend — logic, architecture, systems, and how the pieces fit together. Given a problem, I want to know why it's built a certain way, what the alternatives were, what it costs, and how it holds up two years from now. That habit shows up in most things I build, from platform architecture down to how I structure a fictional universe.

My day-to-day stack runs on Node.js, TypeScript, React and Next.js, with PostgreSQL and MongoDB behind them, shipped through Docker and Railway. Frontend is less of a comfort zone — but I still end up doing plenty of it, this site included.

Outside of code, I'm building a fairly massive narrative world, chasing webtoons and manga, and usually gaming.

Based in: Nicosia, Cyprus · from Lubumbashi, DR Congo
Focus: Backend, architecture, systems design
Also does: Frontend, when the project needs it
Runs on: Late nights, gaming breaks, and a lot of "why"

Architecture and security decisions, not just tickets closed.

Project

Something built end-to-end, on my own

One project, given room instead of competing for space in a grid of badges.

.Flex

An always-running desktop suite that stands in for ten single-purpose apps — file explorer, media player, PDF viewer, image editor, text editor, format converter, QR generator, file-recovery tool, and a paint/vector/3D workspace — behind one shell and one plugin architecture.

Engineering notes

PyWebView over Electron: a local Flask server renders a static frontend inside the OS's native webview — no bundled Chromium runtime shipped with the app.
10 tools (DExplorer, DPlayer, DText, DPDF, DPicture, FormatFlex, QRCode, DRecover, DStudio, DDimension) load as independent plugins; a broken import degrades one tool, not the shell.
Each extension ships its own self-updater — checks, downloads, and extracts a new version in place with a live progress bar.
One static-asset pipeline serves every extension's detail page, carousel, and About section — no per-tool duplication.

Building a world on the side

The other half of the imagination — stories, not systems.

Beyond the code

I've got a big imagination — I build fictive worlds. I'm drawn to webtoons, manga, anime, gaming, long stories, books (novels and short stories), and movies.
