Hello World! Building tools to filter the noise (and sharing the open-source code)

Hey DEV community!

I’ve been lurking here for a while, reading up on architecture patterns and soaking up the knowledge, but I figured it was finally time to step out of the shadows, introduce myself, and share a couple of the things I’m hacking on.

I’m a big believer in building tools that solve systemic headaches. Right now, I'm tackling two very different problems: managing the absolute firehose of weekly todo’s, and fixing how organizations handle sustainability data.

Here is what I am currently building:

1. Weeklymark (Open Source)
   
   I read a lot of articles, docs, and threads, but my todo system was a graveyard of good intentions. I wanted a stupid-simple, clean way to collect leftover todo‘s throughout the week and easily bundle them into a digest format.
   
   So, I built Weeklymark.
   
   It’s completely open-source. It strips away the bloated features of enterprise markdown tools and just gives you a fast, markdown-friendly way to organize your weekly todo list leftovers.

2. ChangePoints.net (Rethinking ESG & Sustainability Systems)

While Weeklymark handles my static links, my bigger project is addressing a massive flaw in how we handle behavioral data.

For decades, sustainability policy has been designed around means, medians, and aggregated datasets. Most sustainability strategies fail not because the science is wrong, but because the strategy treats people as averages. Policy documents cite "the average household", and net-zero roadmaps project behavior change across populations as though individuals were interchangeable units in a spreadsheet. 

They are not. Behavioral change is not a communications problem. It is a systems problem, embedded in the rhythms, norms, and material conditions of everyday life. 

To fix this, I am building ChangePoints.

ChangePoints developed out of rigorous academic research into practice theory, social norms, and policy levers. I took this methodology and rebuilt the toolkit from the ground up. It is now a complete, modern digital operating system built as a comprehensive Notion workspace for practitioners, policy teams, ESG leads, and sustainability consultants. 

Instead of a static PDF, the ChangePoints OS includes: 

• Active Interventions Kanban: Track your current ESG campaigns directly within the framework. 

• Anomaly & ChangePoint Log: Monitor baselines and track shifting behavioral metrics in real-time. 

• Stakeholder Mapping: Manage the actors required to make systemic shifts possible. 

• Historical Reference Library: Pre-loaded with 50 structured case studies spanning energy, food, mobility, and housing. 

If you are working in the ESG or policy space, it is available as a one-time purchase with instant Notion duplication. You can check out the philosophy and grab the OS at changepoints.net. 

Let's connect!

If you are also navigating the chaotic world of building open-source tools, working in Notion architecture, or tackling systems-level data problems, I’d love to connect. Drop a star on the Weeklymark repo if you find it useful, or let me know what you think of the ChangePoints methodology!

Cheers,

Alex
