I’m Christopher Talke a 🇩🇪 🇵🇭 self-taught dev based in Australia.

• Currently working as a DevSecOps Engineer at Regional Australia Bank.
• Previously a Systems & Integrations Developer at Canopi Online.
• Moonlight as an ICT Consultant under Talke Tech.
• On a rare ocassion I will get asked to carry a camera and press record under Talke Media.
• Before all this, I was in Customer Success, Sales, Procurement, and Support, which basically means I speak human too.

I love building stuff for the web, but Automation, DevOps, and Security are where my interests lie right now.

I've got a bit of a habit of finding security issues in the wild, exposed APIs, PII leaks, overly trusting apps, you name it (I'm not hunting for them, I just seem to catch them randomly), here are three notable ones:

• 250k+ accommodation booking records (including staff addresses) exposed via unsecured API and cached in localStorage.
• Hashed passwords and PII stored in localStorage due to misconfigured state caching in production frontend.
• Django debug tools left enabled in production for a live political engagement platform for the 2025 Australian Federal Election, exposing credentials, infrastructure details, and platform metrics showing usage of 500k+ unique users.

So I’ve helped clean up some pretty hairy situations for orgs, no crazy hax or amazing discoveries, just the kind of issues that get through when focus slips and bad practices are in-place.

I’ve written about a few of them here if you’re into that kinda thing.

I mostly work with:

But honestly, I’ll pick up whatever gets the job done, even ol' Excel formulas if that’s what it takes.

This profile is a bit of a dumping ground for stuff I’ve made. Some polished, some half-finished, most of it built to solve problems I had or to learn something new.

• 🕹️ SPT Raid Review, A self-hostable, browser-based replay system for Escape From Tarkov (SPT), because watching back your own failures is the best way to improve... or suffer twice.
• 💼 SwiftCPQ, A configure, price, quote (CPQ) tool for IT consultants with the idea to let you build detailed proposals fast and in a reusable fashion, without the enterprise 💩 price tag.

• 🤖 FindMeARentalBot, A rental property scraping bot to automate property searches.
• 🖨️ Puppeteer in a Container, PDF rendering from HTML via Node inside Docker.
• 🧠 2D Raycasting w/o Canvas, a little brain-bender project using DOM + geometry.
• 📶 NL1901 LTE Inspector, hacked together a modem dashboard out of sheer spite.
• 🐳 Supabase Docker Dev Env, a quick local setup for hacking with Supabase to learn Bash.
• ♦️ Discord Roulette Bot, a discord bot to play roulette with friends across discord servers.

I'll just echo something my old boss said to me...
