Hi, I am an electrical engineer from Canada, and I work on a number of software projects. I am especially adept at customizing open-source software to fit specific business use scenarios. Some examples:

  • Git - customized for private client
    • added a specialized guided merge strategy, to save time on conflict resolution
    • new log format that highlights dependencies of merge commits
    • integrated brotli compression
    • added in-depth analysis and reporting of inter-branch relationship pre-merging
  • openvpn - customized for private client
    • implemented Path-MTU discovery and auto-tuning connection parameters
    • implemented SSL session management to make re-connections instantaneous
    • implemented fast-fallback to enable seamless, fast roaming
    • redesigned main event loop for performance. Each server instance can handle 20k+ clients, up from ~1k
  • Curl - customized for private client
    • integration with libusockets event loop application
    • redesign multi state machine and API to scale perfomance from ~9k to ~40k connections
    • implement latency feedback into DNS resolver cache to prefer closer, faster connections when available
  • Squid - customized for private client
    • implement custom rewriter filter
    • integrate auto-certificate generation for sslbump with local Certificate Authority Issuer
  • unnamed video game
    • implement an algorithm described in an academic research paper as the brains/'AI' of an in-game feature.

I would use your funds to motivate my creativity. Even if the customization you need should remain private, it is inevitable that I will find that adjacent open source projects need some TLC, and I freely contribute bug reports and/or patches to those adjacent projects. (eg, while doing the git work, I found, reported and/or fixed some issues in a JWT library, graphing library, and curl and based on the new expertise gained I was able to answer some previously unanswered StackOverflow questions). Most projects are connected together in some ways. Funding one inevitably benefits the neighbours in unforeseen ways.

This will suggest a need exists to focus more on open source customizations. Would your business benefit if the OSS you use were better fitted to the purpose? You can make it happen. Sponsor me to fix what irks you.

A small bug or bounty question.

Small means something you'd expect to take 1-2 hours of skilled effort.
It might take longer to complete (wall time), but should require around this level of effort.
Be sure to let me know what the bug is (a @drok mention works)

  • One bug or medium sized bounty

"Medium sized" = something you estimate would take 1-2 days of skilled effort.
It could a be a bug-fix, or even a bounty question "how do I get program X to interact with Y and accomplish Z"; a puzzle that might take 1-2 days of research like "reading the source"?

The work might take longer to complete.
