Hi, I'm Harry Altman! I was the maintainer of Truffle Debugger (https://github.com/trufflesuite/truffle/tree/develop/package...), a Solidity smart contract debugger, for 5 years. I eventually ended up writing my own decoding and encoding libraries to support it, as well as a bunch of other things.
I'm good at this sort of nitpicky work, spotting and thinking about edge cases. I like getting things exactly right, even though that obviously isn't always possible due to various constraints. I've been kind of wondering if I should get into embedded development; I find it appealing when things are low-level or similarly constrained. I've beaten Microcorruption. :) (The original levels, I haven't played the new ones.)
I'm also quite interested in unusual or obscure data formats, and working on Truffle Debugger and its associated libraries certainly involved a bunch of having to figure undocumented formats and interfaces. :) I put down above what languages I've worked substantially in but I'd say I'm a generalist and will figure out whatever you give me (I knew approximately no Javascript, Typescript, or Solidity when I started working at Consensys).
I'm a mathematician by background and in my spare time, so after the Truffle Debugger project was shut down I took some time off to focus on my mathematical projects. But now I'm looking for work again! If you need someone like me, I'm available for hire!
