Crucial Exams

Continuing to build https://crucialexams.com/, a platform that helps people prepare for IT certifications like CompTIA, AWS, and Microsoft/Azure. It offers realistic practice tests and study tools. I also have partnered with educators and universities who now offer it to their students and get dashboards to review student progress and identify where they are struggling.

ExploreJobs.ai

I'm working on 2 projects right now: 1. Fluxmail - https://fluxmail.ai Fluxmail is an AI-powered email app that helps you get done with email faster. I think there's a significant opportunity for AI to change the way we use email, and I'm experimenting with ways to improve the status quo. I'd love to hear what features you'd like to see in such an app! 2. ExploreJobs.ai - https://explorejobs.ai This is a job board for AI jobs and companies. The job market in AI is pretty hot right now, and there are a lot of cool AI companies out there. I'm hoping to connect job seekers with fast-growing AI companies.

Ghostty

I'm working on a notes app that is as simple as Apple notes, but has native markdown support and uses semantic search. Uses SwiftUI for the UI, and Zig does most of the heavy lifting on the backend. It's inspired by ghostty which uses a similar setup[1]. Right now it only works for Mac, but I'll be porting to iOS as soon as I get the markdown renderer polished. It's not available to the public yet, but I'm using it as my daily driver and hope to release it later this year. I've open sourced it. 1. https://ghostty.org/ 2. https://github.com/emmettmcdow/nana.

I'm working on Macscope (https://macscope.app), a better Cmd+Tab for macOS. I built it because macOS window management feels slow compared to the keyboard-driven speed of a terminal or code editor. It augments your existing muscle memory: a quick tap of a shortcut switches apps like normal, but holding it opens a powerful interface with features like: Unified Search: Instantly find any window, app, or browser tab. Scopes: Save and restore entire window layouts for different projects (perfect for after you unplug a monitor). Placement Modes: Snap windows to screen halves as you switch to them. The goal is to make the OS feel as fast as my other tools. I'm always looking for feedback on how to make window management less frustrating!

Simple Observability

I’m still working on Simple Observability: https://simpleobservability.com I built it because I needed two things: - A super easy-to-install monitoring tool that doesn’t require bash scripts or config files - A mobile-friendly, UX-first interface where I can check everything from my phone It’s now pretty feature complete. I can see a full picture of all the servers and VPS I run straight from my phone. Setup is one command, no config files, and everything else happens in the UI. There’s a catalog of predefined alert rules, and creating new ones is easier than anything else I’ve used. There’s a free tier if anyone wants to try it!

Thumbnail.ai

I'm working on an AI thumbnail/graphics maker using the various image models. https://thumbnail.ai/ You just upload a picture and pick a design type and it generates a thumbnail for you. Got good feedback last time I posted, steadily and slowly growing now.

With Audio

* Non-technical: The product has seen some success with minimal marketing, but I keep getting distracted by spending too much time on technical work. I know I need to do more for marketing but I keep going to my safe space (my IDE). I believe in the product but it keeps reminding me how difficult is to get it to a polished, finished state for all users. Appreciate any feedback. https://desktop.with.audio.

Vedro

I'm working on Vedro, a Python testing framework as a pytest alternative without the magic and with clear output. The main idea is that tests should just be Python: plain `assert` statements instead of custom matchers, no fixture magic, and when tests fail you get readable diffs that actually show what went wrong. Tests can be simple functions or structured with steps that self-document in the output. https://vedro.io I would be very happy to receive any feedback!

Medium

Https://doctly.ai We're build Doctly.ai - PDF Extraction with AI. We started out with document conversions to Markdown but quickly realized that most use cases were for JSON conversion. We recently launched our "Extractor Studio" where you can have AI analyze a few sample variations of your documents and come up with a schema for you and publish it to an API endpoint. We've built a technique on top of AI models that dramatically improves run to run consistency of JSON output. Checkout the blog post here: https://medium.com/@abasiri/introducing-doctlys-extractor-studio-a-faster-way-to-build-pdf-extractors-999093a0ad11.

Ganttify

I’m building Ganttify for a while now https://gantt-chart.com The goals is to become THE Gantt chart add-on for anything. Currently works with Todoist, Basecamp and Trello. I’m struggling to find more markets. It’s basically “Turn X into an editable timeline with syncing capabilities and dependencies” Open to suggestions and ideas how I can make this take off. I’m currently in the process of consolidating every integration into a single account. Previously (currently) it was “Ganttify for Trello” or “Ganttify for Basecamp”. It will become “Ganttify, connect one or more integrations to your liking”. That might help simplify things for users I suppose.
