I’m Nicolas Tenn, a technical product manager in Miami.

Hardware. Software. Data. I build the clean tech products where all three meet.

Data pipelines for solar arrays at Boeing. NASA programs, proposal to delivery. A Mac app with Apple Intelligence, built and shipped solo.

The drawing above is the long game. Machines that build the next machine from what’s already on the ground. It starts on Earth.

Now

Mac app Encore

Everything you copy, ready for an encore. A clipboard that lives in the Mac menu bar, where Apple Intelligence titles and rewrites what you copy, on device. No account, no cloud. Designed, built, shipped, solo.

Source on GitHubComing soon to the Mac App Store.

Encore’s menu bar popover on a Mac desktop, listing pinned and recent clippings with the apps they came from. The headline reads: Everything you copy. Ready for an encore.

Encore’s History window. Long clippings carry short titles such as Flight confirmation email and Retry function definition. The headline reads: Know what you copied at a glance.

A casual message, rewritten by Apple Intelligence into a professional one, inside Encore’s popover. The headline reads: Rewrite it before you paste it.

A copied price of 1,249 euros, converted to US dollars, pounds, yen and Canadian dollars at European Central Bank rates. The headline reads: Copy a price. See it in your currency.

Encore’s Privacy settings, ignoring passwords and apps such as Keychain Access and Terminal. The headline reads: Your clipboard stays yours. No account. No analytics. No tracking.

Selected work

Design and analysis engineer Boeing
Solar array design ran on manual workflows. I replaced them with machine-readable data pipelines, built in Python and local LLMs. Adoption grew tenfold.
Lead product engineer NASA
Wrote the winning proposal. Built the team. Shipped a hardware-integrated computer vision platform, sensors and software working as one. Then presented it, solo, to the review panel at Kennedy Space Center.
B.S. Computer Engineering University of Central Florida
Computer engineering, from silicon to software. On NASA student teams I wrote the embedded code, assembled the hardware on site, and helped deliver a prototype planetary rover.
