Ask HN: What are you working on? (February 2026)

I'm a solo dev founder working on Potniq (https://potniq.com) - a business travel tool that tells you exactly when to leave based on your entire itinerary.

I used to work in devrel, and traveled a lot for events, and I always struggled skipping things like workouts, looking at the time on the last day of a conference trying to check whether it's time to leave yet - so this gives me the opportunity to build a tool I would have loved to use.

Currently I'm working on a LLM-powered booking email parser, that ingests forwarded booking confirmations and adds flights, hotels, etc. to your itinerary.

I built https://measuretocut.com after too many DIY projects ended with another trip to the hardware store. It figures out how much material you actually need and how to cut it to minimize waste or costs. When I released it in December it just handled 1D cuts for things like boards, bars, and pipes. You enter what you need, and it lays everything out visually on stock lengths. This morning I released the 2D sheet cut calculator to do cut plans for plywood and similar sheet materials. Any feedback is welcomed from fellow engineers turned woodworkers!

Orchestera (https://orchestera.com/) - Fully managed Apache Spark clusters in your own AWS account with no additonal compute markups, unlike EMR and Databricks.

Currently implemented the following:

- Automated scale in / scale out of nodes for Spark executors and drivers via Karpenter

- Jupyter notebook integration that works as a Spark driver for quick iteration and prototyping

- A simple JSON based IAM permissions managementent via AWS Parameter Store

Work-in-progress this month:

- Jupyterhub based Spark notebook provisioning

- Spark History Server

- Spark History Server MCP support with chat interface to support Spark pipeline debugging and diagnostics

Open to feedback and connecting. Docs at https://docs.orchestera.com/

I’m building Historic, a private AI video journal for founders.

You record short morning, evening, or ad hoc sessions, and it transcribes and indexes them into a searchable archive of your thinking. It uses simple Apple Fitness–style rings to encourage consistency, plus monthly insight reports and suggested “build in public” posts.

I built it because notes apps weren’t capturing my thinking in full fidelity. Using Reflect I averaged ~65k words per year. With Historic I logged ~85k words in one month.

Your thoughts are already your most valuable asset. Historic just makes them accessible.

Still no actual game of course :')
