Why I'm Writing This

After 13 years of shipping code, I'm finally documenting what I've learned building trading platforms, AI tools, and everything in between.

Why I'm Writing This

I've been building software professionally since 2011. Started with VBA macros and Access databases. Now I'm shipping AI-powered apps and crypto trading terminals. Somewhere along the way, I realized I'd learned a lot of things the hard way that might be useful to others.

What I Actually Build

My work falls into a few buckets:

Trading & Crypto — I built my first altcoin trading bot in 2014. Since then I've shipped copy trading platforms, NFT marketplaces, and most recently Hyperscalper, a fully client-side trading terminal for Hyperliquid. Zero backend. Your keys never leave your browser.

AI Integration — Not building foundation models. Building with them. Language learning apps, legal document analyzers, ad creative generators. The interesting part is figuring out where AI adds value and where it's just hype.

Enterprise Architecture — I spent 3+ years at AWV transforming a maintenance nightmare into a proper monorepo with 8 Angular apps. Also architected frontend systems at Fednot. The unglamorous work that keeps large teams productive.

Weekend Projects — iOS apps, Garmin watchfaces, e-commerce platforms. I ship a lot. Most things fail. Some stick.

Why Write Now

Three reasons:

1. Writing clarifies thinking. When I wrote the Hyperscalper deep-dive, I found bugs in my own mental model. Had to actually understand my code to explain it.

2. Documentation for future me. I've forgotten more architectural decisions than I remember. Writing them down means I won't have to re-learn the same lessons.

3. The internet gave me a lot. Stack Overflow answers, random blog posts, open source code. Time to contribute back.

What To Expect

Technical deep-dives into things I've actually built. Tradeoffs I faced, decisions I made, bugs I shipped. No "10 Tips for Better Code" listicles. No content for content's sake.

I'll cover frontend architecture, AI integration patterns, crypto/trading infrastructure, and the occasional career observation. Probably some Swift and mobile stuff too — I've been shipping iOS apps lately.

If something I write saves you a few hours of debugging or helps you avoid a mistake I made, that's the goal.
