Each card is a bet. What the pain was, how I answered it, and where it stands today.

DIGEST

AI research digest for arXiv

Visit digest.ltd
The pain

AI research moves faster than any person can read. Discovery isn't the bottleneck — filtering the flood into what actually matters to you is.

My solution

A personalized daily digest of arXiv papers, ranked around your interests and streamed to your inbox before the day starts.

Stampo

Digital loyalty cards for small businesses

Visit stampo.cards
The pain

Paper stamp cards get lost, smudged, and left in the wrong jacket. Small businesses lose the loyalty touchpoint entirely — and repeat customers lose the reward they earned.

My solution

Digital stamp cards that live in Apple Wallet and Google Wallet, right next to the boarding pass. The merchant scans, the customer taps, the reward always survives the laundry.

The multilingual tokenizer tax, measured across 16 Asian languages

Visit doi.org/10.5281/zenodo.21069313github.com/Helmo21/asia-fertility
The pain

LLM tokenizers structurally overprice non-English languages by 3–12× on the same content. Most teams pay the tax without ever seeing it in a line item.

My solution

A reproducible measurement across 16 Asian languages that turns 'language difficulty' into a procurement decision — with every run pinned to config, prices, and tokenizer versions.
