every block below actually hashes the one above it. I checked. twice.

building on solana · learning rust · awake before you

I started with web development, got curious about blockchains, and then made the questionable decision to find out what actually happens underneath all the abstractions.

Now I'm learning Rust, building on Solana, reading more docs than is strictly healthy, and figuring out why this particular transaction failed.

Started by making things work in the browser. Stayed because apparently I needed to know what was happening underneath it.

web development

Made things move in the browser. Assumed that was the whole job.

MERN

Built enough CRUD apps that the CRUD stopped being the interesting part.

TypeScript / Next.js

Types turned out to be past-me leaving notes for future-me. I like both of them more now.

blockchain

Opened one whitepaper out of curiosity. Structurally, this is where the portfolio comes from.

Ethereum / Solidity

Learned what gas is. Learned what a revert is. Learned to read stack traces properly.

Solana

Accounts instead of contracts, rent instead of gas. Fast enough that my mistakes arrive immediately.

Rust — currently here

Somewhere between learning Rust and negotiating with the borrow checker. It's still winning, but by less than last month.

THINGS I'VE SURVIVED

                    — MERN, start to finish
                    — Solidity, and its opinions
                    — web3 tooling that changed under me
                    — deployment bugs that only exist in production
                    — CORS. all of it.
                    — env vars that worked locally and absolutely refused to work on Vercel
                  

                learning: rust

Things I've built while figuring things out.

What's actually on my screen right now, rather than what sounds good on a résumé.

→Learning Rust properly - not tutorial-properly

→Building on Solana, mostly with Anchor

→Reading Solana internals: accounts, rent, CPI, the runtime

→Poking at blockchain infrastructure to see where the edges are

→Looking for people building something interesting, to build it with them

→Running on an amount of coffee that would concern a doctor
