Position: iOS/macOS Product Engineer
Category: iOS
English level: upper
Years of experience: 5

I'm good at teaching and sharing knowledge. I'm very curious about things, and I like to apply knowledge from the adjacent fields—design and copywriting.

I do a lot of side projects and have a good command of product development, alas I have not made them super sustainable—making apps alone is hard.

More technical stuff:
I wrote ransomware protection apps, I used plain C for better performance. The apps used lots of cryptography, and low-level APIs to observe processes(forcs, execs, pid groups, etc.)

Once, we needed to encode some information inside a font to track a user, for marketing purposes, on the Web. I came up with a solution using some weird metrics and heuristics inside font format API. Not the most ethical stuff but it did its job. The user could be tracked after uninstalling our app on the Web (it was in times when local fonts were used for tracking).

I worked on hybrid apps where native and web combined for fast prototyping, and we were able to build apps under a two-weeks deadline steadily.

I'm okay with IPC, if you need to develop an app using XPC architecture with lots of multi-threading—go for it.
I worked both as an iOS and macOS engineer on large consumer apps. I have experience in leading a team. Also, I'm a UX nitpicker and consider it part of good engineering.

I spent plenty of time working as an RND researcher, primarily focused on security and breaking OS/API limitations. 

I can choose between different tech stacks to solve a problem most efficiently. 

I'm good with architecture, but sometimes can be bogged down and slowed by technicalities. I'm working on becoming more sustainable to get results faster.
Companies bigger than 50 people won't do for me; social products are not my cup of tea either.

I'm interested in anything hard, unsolved, and involving real users with their problems. A founding engineering role would be ideal.

Startups—YES!
