DIGITAL IDENTITY — FILE 001
COBALT
Backends, bots, tooling and the infrastructure they run on. Mostly self-taught, built by breaking things first.

About
PERSONAL FILEI'm Cobalt — a 20 year old hobbyist developer who spends most of his time building and maintaining software that has to keep running when nobody is watching.
Usually that means backends, bots, small tools and the infrastructure underneath them. I like working across the whole stack: servers, networking and DNS, reverse proxies, and the interface people actually end up touching.
Almost all of it is self-taught. I learned by building things, breaking them, and figuring out how to put them back together — which is still, by some distance, the fastest way I know to understand a system.
Arsenal
BEST → STILL LEARNING-
01
C#
MainMy primary language. Tools, backends and most of what I actually ship.
05/05 -
02
Python
StrongScripting, APIs, bots and anything that should have been automated yesterday.
04/05 -
03
Lua
StrongYears of gameplay systems and scripting, most of it on Roblox. Where it started.
04/05 -
04
JavaScript
ComfortableFrontend work and Node backends — including the page you're reading.
03/05 -
05
Elixir
BasicsStill learning. So far mostly circling how it handles concurrency and failure.
01/05 -
06
Rust
BasicsJust started. I can follow the code, but I haven't built anything real with it yet.
01/05 -
07
C++
BasicsI can read it and make small changes. I don't write much of it from scratch.

Domains
WHAT I WORK WITHNetworking
Routing, ports, firewalls and VPNs — plus working out why one machine refuses to see another.
Backend
APIs, databases, bots and services that are expected to stay online without supervision.
Frontend
Interfaces that load fast and stay out of the way. Motion only where it earns its place.
Domains & DNS
Domain setups, records, SSL, reverse proxies and the mail configuration nobody enjoys.
Self-Hosted Servers
Built and run my own servers for games that never shipped with support for it.
Hardware
Builds, upgrades, troubleshooting, and assembling servers from loose parts upward.
Systems
Windows and Linux, deployment pipelines and the monitoring that tells you it broke.
Reverse Engineering
Non-professionalTaking software apart purely to understand how somebody else decided it should work.
Record
2016 — PRESENT-
2016ENTRYRoblox Studio
First line of Lua
Opened a game engine to change one number and stayed for the scripting. Everything after this is downstream of that afternoon.
-
2018SCRIPTOutside the engine
Picked up Python
The first language that wasn't tied to somebody else's game. Scripts that ran on my own machine and did whatever I told them to.
-
2019NETWORKrequests
Found out how the web actually talks
HTTP methods, headers, status codes, auth. Once
requestsclicked, every service on the internet turned into something I could script against. -
2020WEBNode.js
Started building the web, not just calling it
Moved from consuming APIs to serving them. Node backends first, then the frontend on top — which is where the interface side of this finally started to matter.
-
2022TEARDOWNNon-professional
Took things apart to see inside
A stretch of reverse engineering, purely out of curiosity. Never professionally — but nothing taught me more about how software is actually put together.
-
2023BACKENDC# / .NET
Backends in C#
Swapped scripting habits for a typed language and a real compiler. Services built to stay up on their own rather than to run once and exit.
-
2024TOOLINGConsole → interface
From console tools to real tools
Started with command-line utilities for my own problems, then gave them interfaces, installers and error handling — the unglamorous part that makes something usable by someone else.
-
2026NOWCurrently
Elixir and Rust
Two languages that disagree with my habits on purpose — one about concurrency and failure, the other about ownership. Both are still very much in progress.
