Porting LevelDB[1] to Seastar[2], for internal metadata storage in Redpanda[3]. Before you ask why can’t something off the shelf be used, seastar has unique constraints around its runtime and its memory allocator that means we can’t reuse an existing library.

Prediction model for false positives to help my University SOC.

Automatic dataset builder and cleaner. (End product would be something like, you type that you want a dataset for dog breeds, and it builds and cleans the data automatically)

A flashcard app for my main stakeholder (My wife)

I’m working on an AI-powered page optimizer for SaaS & eCom sites: https://peakagent.ai

No complex setup – drop in a script, keep your existing stack

Auto-generates variants for hero, copy, CTAs, and social proof

Continuously tests and routes traffic to the best-performing variants

Optimized for key pages (pricing, signup, product, checkout)

Reports focused on conversion & revenue lift, not just clicks

Would love feedback, tear-downs, or ideas for must-have features before you’d trust this on your main pages.

PS: Deeper ad→page→revenue attribution + personalization by segment coming soon.

I suspect AI company want improved efficiencies and developing a framework that can be applied in determining the minimal-energy, maximal-efficiency architecture for ai models. Calculating the precise limits, like a Cognitive Event Horizon, where a model becomes so complicated it literally costs more energy to run than the knowledge it provides, and the Semantic Horizon, where it simply gets too complex to be accurate, etc. Lots of cool implications such as around a fundamental mathematical maximum learning rate which results in trying to get anywhere close to that that by doing stuff like aggressively filtering of the data.

Basically small data tools for myself.

A non-bloated HTML, CSS and pure Vanilla JS framework to create dashboards.

A cross-platform JSONL viewer where I am learning ImGUI. Haven’t found any other open source GUI framework that‘s small, provides out of the box components for tables, sorting

An open-source, local database which collects all your personal data, hooks it to an LLM (BYO), and gives you an assistant that can answer any question about your life.

It also allows you to vibe-code (or just code) small apps on top of your data (e.g., your custom dashboard for your expenses).

I have a short demo here: https://www.youtube.com/watch?v=gqAyvENDjSA

I've been exploring getting some deeper experience with Claude Code (my org only allows Copilot) and exploring vibe coding by using CC to design a functional programming language that transpiles to JS and build out a full language specification and the tooling to go along with it. I haven't pushed anything to Github yet but it's been very educational, and also a little terrifying to see how easy it is now to produce tens of thousands of lines of code that you totally don't understand.

I am building Mizu, a lightweight web framework for Go that aims to keep things simple and Go-first. Everything is written in plain Go with no hidden abstractions, and you can start with a single file then grow into a full project without changing your coding style. The name means "water" in Japanese; the framework tries to flow with your code rather than force its own patterns.

For the first time in years I'm working somewhere that doesn't use JIRA or Trello and find myself without a Kanban system. I'm having serious withdrawals. I have limitations on using a non-approved IT system because I use customer data so I vibed a PWA Kanban system. Stores data in browser and only vanilla code. No external dependencies.
