Professional
I am a finance and technology leader with extensive FinTech, blockchain, cyber security and international banking experience. I have a proven track record of leading teams to successful execution of high-quality, production ready technology products.
In mid-2023 I sold my last venture through private sale. RT Reporting, which I co-founded with my brother was a cloud-based advisory and financial forecasting product for accountants and virtual CFOs. I led the technology build out and the development of the product and IP.
I have held various engineering and technical leadership roles, primarily focused on digital transformation, blockchain, AI integration, FinTech and data solutions.
My international banking and finance experience spans more half a decade across Australia and New York with ANZ Bank and later Hong Kong with the Hongkong Shanghai Banking Corporation. During this time I worked across financial institutions coverage, including: funds, hedge funds, banks, public sector and insurers.
Background
Born in Melbourne, Australia, I was fascinated by the world, languages and technology from a young age. As a young kid I would listen to the BBC World Service on radio late into the night, a habit I've never kicked although these days its podcasts and books.
My first computer ran a Pentium III 733mhz processor and introduced me to the world of technology, gaming and programming. While I spent my 20's studying and working in international finance, I finally came full circle in 2018 when I left banking and turned my life long passion for tech into my profession.
Based in Chiang Mai, Thailand. I enjoy exploring, hiking, motorcycling, travelling and discovering new places. I have a passion for languages and culture. I am fluent in German, and conversant in Mandarin and Spanish.
I have been blessed to live all around the world, including Germany/Austria, China/HK, Thailand and spend significant stints in the USA, Spain, Malaysia and Mexico.

Technology I Use
Operating System: I use Arch linux mostly (checkout my guide/tutorial here). I have also used Fedora and Pop!_OS extensively in the past.
Desktop Environment: I use System76's Cosmic DE. It is still rough around the edges, and so you might also see me using the Qtile tiling window manager in some of my videos.
Email: I use Proton Mail. (PGP Public Key can be downloaded here).
Messenger: I use Telegram.
Browser: I use LibreWolf. (A custom version of Firefox, focused on privacy, security and freedom).
Text Editor: I use NeoVim. Specifically, I use a minimal, pluginless configuration which can be found here.
Code Editor: In 2026 I am experimenting with Zed. I used to develop exclusively with NeoVim and TMUX. Check out my NeoVim + TMUX course here.
Precious Metals: Yes, precious metals are a technology - specifically a monetary one. I have been an investor in silver and gold for 15+ years. On the balance of probability, I believe that the current monetary system will expire within the next decade. I also believe however, that while in the long run pessimists are right, optimists are rich.
Crypto: Monero is the most promising major cryptocurrency presently available. I consider BitCoin to have run its race (precious metals are a more robust store of wealth, but crypto can still facilitate payments).
Phone: nothing better embodies the failure of modern technology to improve our lives than the mobile phone. I (reluctantly) use a Google Pixel 8.
Camera: my YouTube videos are filmed on a GoPro Hero 10.
AI: In 2026 I have started using Google's Gemini model for some development tasks. You can read my thoughts on AI here.
Languages: I am most proficient in JavaScript/TypeScript and Python. I also have experience with Golang, C, Lua, Rust, Solidity and Bash/POSIX shell scripting.
Libraries & Frameworks: This website is built with rssg, a Static Site Generator I coded in Rust. I have also used Vue.js/NUXT.js, FastAPI, Gin, tRPC, gRPC, Express.js, Django, as well as frameworks that should never have seen the light of day (React.js/NEXT.js). I have extensive blockchain development experience (hardhat, ethers, viem).
Cloud: I mostly use AWS for my commercial projects. Cloudflare and self hosting with old PCs for my personal work.
Databases: I love MongoDB, and it is usually sufficient for what I need. I also have experience with SQL databases such as Postgres and MySQL along with in memory databases (e.g. Redis).
Shell: I use zsh.
eSIM (travel): I use Saily (use code: RADLEY4599 for US$5 credit).
Machines: My main machines are a Lenovo ThinkPad P1 Gen 8 (review here) and a t480 Lenovo ThinkPad (youtube video here). I use an older ThinkPad t440p as my home server.
Keyboards: I am a big believer in high quality keyboards for long writing sessions. I use a GMK67 65% custom keyboard. Other than this, I also have a Ducky Mecha Mini v2 and Keychron K8 Wireless Mechanical Keyboard.
Mouse: I use a Logitech MX Master 3s as well as a Logitech G Pro Wireless.
Monitor: I use a EX2780Q 144Hz Gaming Monitor with HDRi Technology | BenQ.
