Knowledgable & helpful person, available for hire :-)
I'm looking for more work, ideally on a consulting / freelance / part-time basis.
LinkedIn is better than email to make first contact if you'd like to talk, whether for work or just chat about something you liked here on HN! (I often miss interesting one-off mails among the deluge, and don't check it every day.)
I work 80% time at a funded stealth startup as hands-on tech lead, with zero-knowledge (ZK) cryptography, Bluetooth low energy (BLE), and peer-to-peer distributed systems, linking physical devices as well as the usual web stack. Can't say more, but it is intended to become open source. This a really fun and challenging project, with a great team! (It's not on my LinkedIn - stealth).
With my remaining 20% I am currently available and looking for software dev and/or tech leadership and/or business strategy consulting.
I'm versatile but develop mostly low-level or "system" software in C, C++, Go, Rust and Nim, with Linux as my main OS (but MacOS and Windows also). I have about 30 years professional dev experience over a wide range of systems, from embedded to supercomputers, Linux kernel, database engines, as well as GUIs, the web, and even games. Good at performance optimisation, debugging. Also good math & physics.
I've worked as an Ethereum core dev (EVM), so I know that environment well, especially improving EVM database speed, which is a critical factor! Currently my rabbit holes are ZK cryptography speed optimisation, and a novel fast database engine (neither B-tree nor LSM-tree, but with characteristics of both).
(ZK = zero-knowlege cryptography).
