02 / Personal lab

The things I build
for myself.

Coffee recipes, a family collection, home routines, and a smaller internet for my girls. Personal problems make excellent reasons to learn something properly.

Built outside my role at Terakeet. My employment experience lives in my resume ↗.

Product design / Applied AI / Calibration

A better cup, with a memory.

Coffee Dialer connects the bag, the equipment, and the history of each brew. Extraction gets a recipe into the system; calibration makes it usable; a shot log makes the next adjustment informed.

The question

How do you turn somebody else’s recipe into a useful starting point on your equipment?

Engineering takeawayAI gets the information in. A thoughtful data model and a habit of recording outcomes make that information useful.

02Home automation

A house that pays attention.

A collection of smart devices became a coordinated system: local signals describe what is happening, named zones give those signals context, and a shared message bus connects that context to action.

Question

How do you automate a home without writing a separate rule for every room?

Engineering takeawayThe real product is the coordination layer: a way to make many small devices behave like one understandable system.

03Computer vision

An inherited collection. A second look.

An overhead camera, independent image and text reads, and an explicit rules layer turn album pages into an inventory and a manageable queue for closer inspection.

Question

What if the label is the very thing you need to verify?

Engineering takeawayThe useful output is not a confident-looking prediction. It is an inventory with the uncertain and interesting parts made visible.

04Web / Parenting

A small internet. By design.

A hand-curated directory, a restricted browser shell, and a network allowlist shape a deliberately small browsing experience. The interface is simple because the boundaries underneath it are explicit.

Question

What changes when the goal is a finite set of choices rather than more time on screen?

Engineering takeawayThe visible product is a handful of tiles. The engineering work is keeping the experience aligned with that small, deliberate promise.

ANOTHER SIDE OF THE PORTFOLIO

Personal curiosity. Practical experience.

These are personal systems. The independent work and career history elsewhere on this site cover the professional side.
