ABOUT ME
Software Engineer, 10+ years experience, CTO at FinTech & AI startups
Software Engineer, 10+ years experience, CTO at FinTech & AI startups
I wrote my first computer program at the age of 12 to do my physics homework for me (15 years ago).
Since then I’ve learned 12+ programming languages, graduated Computer Science with 1st class honours, sold a profitable business, worked at challenger stockbroker Freetrade, built a stock exchange for real estate (Proptee), built an AI assistant (Molin AI), read 100 books, and spent thousands of hours learning.
My hobbies include finance, crypto, rationality, optimization, PKM, fitness, and anti-aging.
I’ve been mentoring since 2015, which makes me a Codementor OG.

Highly proficient with the latest web standards including: ES6 and web components; modern frameworks such as Vue.js, React, Next.js; modern tools such as esbuild, vite, prettier, eslint, etc.
I come from the days of Macromedia, jQuery, and Backbone.js. I was part of all the subsequent trends: AngularJS, Flux, React. Does anyone remember Bower, Grunt, and Fluxible?

I have experience with unit/functional/e2e/snapshot testing, REST APIs, SSE, WebSockets, databases (e.g. MongoDB, PostgreSQL), ORMs, and many other tools.
I still remember the first time I created a node.js app. It was a simple HTTP server. I love how easy it was to create it: just 1 file, a few routes with req/res, done.
Nowadays the stacks are a lot more complicated, but you don't have to figure it all out on your own. I'm here to help you with any issue.

I have production experience with: query optimisation, schema management, rollbacks, backups, disaster recovery, self-hosting, user management, extensions, procedures, triggers, transaction isolation, encryption, upgrades.
At Proptee I built a stock trading engine, double-entry bookkeeping system, and additional internal tools (campaign management, KYC/AML) on top of PostgreSQL.

I have experience with popular IDEs, Kotlin, Java, the latest releases of Android, build systems, advertising SDKs, Google Cloud Messaging, Firebase, Facebook/Google SDK, Square's suite of libraries and many others.
When I was 18, I jumped head-first and created my first Android apps. One of them had over 50,000 users and made my mom proud when I showed her the first $100 I earned on the internet.
Since then I've built many more apps, both on Android and iOS, in multiple languages.
