    Discontinued AI-based Pull Request Summarizer and Reviewer with Chat Capabilities.

  • FluxNinja [0] founder here. I developed an in-house AI-based code review tool [1] that CodeRabbit is now commercializing [2].

    I did it because of the increasing frustration due to the time-consuming, manual code review process. We tried several techniques to improve velocity - e.g., stacked pull requests, but the AI tool helped the most.

  • routerino

    Tiny, SEO-focused router for React websites

  • I have had to build landing pages for various products of my startup, and I was annoyed that there wasn't a great way to handle the sitemap generation and SEO metadata together with the route configuration.

    So, Routerino was born. It's very early still, but it works great for my needs. It is built to work together with pre-rendering, so that a client side rendered React app can have good SEO performance. I experienced this problem while working for a large blog company that faced many SEO issues from using Angular & React SPAs.

    I'm working on vastly improving the documentation and hope to release that soon. Repo if interested is at https://github.com/nerds-with-keyboards/routerino

PHP, ASP.NET Core, and Node.js.

  • data-drift

    Metrics Observability & Troubleshooting

  • We used static testing framework like great expectations but that was not enough. We did not have the budget for the big data observability players like Monte Carlo, so we kept it simple.

    Repo if interested: https://github.com/data-drift/data-drift

    (Disclaimer: I am focusing full time on this project to see if it's an interesting business opportunity. It's 100% open-source -- feedback welcome!)

  • I wrote a kafka connect single message transform (SMT) to remove PII fields embedded in json messages:
