16 KB page size (Android)

Newer Android devices use 16 KB memory pages; apps with native libraries built for 4 KB pages must be rebuilt or they will not run there.

Pure Kotlin or Java code is not affected; native .so libraries are, including ones pulled in by React Native, game engines and SDKs. Each must be aligned to 16 KB, which recent NDK versions do by default, and Google Play requires support for apps targeting Android 15 or higher on 64-bit devices. The fix is often an SDK update, sometimes a library swap when the vendor never updated it.

Target API level (Google Play): The Android version an app declares it was built for; Google Play raises the minimum every year and hides apps that fall behind.
Dependency updates (Dependabot, Renovate): Keeping libraries and frameworks current, usually with bots that open pull requests for new versions.
LTS and EOL (long-term support, end of life): LTS is a release supported with fixes for years; EOL is the date after which a version gets no more security fixes at all.

“a true bias for action” client CTO, public LinkedIn recommendation

Confidential by default. NDA is standard. I never show your project, name or screenshots without written consent, which is why this site names no clients without permission.
Your code, your accounts. Code and data stay in your repository and accounts. AI tools run with training on your data turned off, and secrets never reach a model.
A handover you can use. Every project ends with the same checklist: a README that gets it running, one architecture diagram, written decisions, CI, a runbook and a recorded walkthrough. It is done when someone outside the project can run it from the docs.
Boring technology where it counts. I pick a stack you can hire for. Anything experimental needs your yes and an exit plan.
Approach matched to your risk appetite. Prototype, product or regulated: the level decides how much autonomy the agents get and how much review and validation each change needs.
Everything checkable. Every number on my pages links to its source. My tools are free, and the idea validator skill is open source (MIT).

My pledge

Reply within 24 hours. I reply within 24 hours on working days, personally, not a bot. Weekend messages: by Monday noon.
Late means free. If I am late, the first hour of work is free. You do not have to ask.
Scope in writing within 24 hours. A free 30-minute call with no company deck, then the scope and the price in writing within 24 hours. You decide.
The person who does the work. You talk to the person who does the work. No sales layer, no handoff.
Follow-up only with news. I follow up only when I have something new for you. Never a "did you see my offer".
Honest "not a fit". If I am not the right person, I say so on the call and point you to someone who is.
