I’m working on a platform that makes it easy for people in West Africa to buy and sell cryptocurrencies (like USDT, USDC, ETH, BNB, POL, AVAX, etc.) directly with mobile money — the most popular payment method in the region.

The goal is to bridge crypptocurrencies and local mobile wallets to make crypto useful in everyday life — not just for trading, but also for online payments.

A few key features:

Mobile money integration (MTN, Moov, Orange, etc.)

Instant buy/sell of USDT, USDC, ETH, and other assets

Crypto payment gateway — businesses can now accept stablecoin payments directly on their websites

I’m currently focused on improving liquidity and expanding to more countries.

Would love feedback from the community — especially around :

- Liquidity and Marketing to find the first users.

Happy to share more details or collaborate with anyone working on similar problems.

building a location-based game that captures Taiwan's absurd convenience stores density[1]. Players stand at any 7-11/FamilyMart/etc, take a photo showing you can see the next store, walk to it, repeat. Chain as many stores together as you can.

It sounds silly but Taiwan really is this convenient - you often can see 2-3 stores from one spot. Here[2] one route where you can actually link 7 convenience stores in a row! Now trying to make maps look a bit nicer with mapbox.

system to test and calibrate an analog traction control system. the system uses a frequency to voltage converter and a bunch of opamps to compare wheel speeds then determines wheel slip or slide and either reduces engine power or braking.

Test system uses ADCs, DACs and a DDS to produce a sine wave that simulates wheel speed.

I would rather be fishing.

Developing a fingerprinting method for identifying music masterings! Like Shazam but to tell what version of an album you have.

The idea being able to compare measurements to see what mastering you're really getting - because they are NOT all equal. With the remasters and stealth replacements on streaming, it seems like every other month I wake up one day and my favorite music sounds worse (or is gone...). Now I can measure it and help find what versions I really want to collect!

I may end up trying to make a fingerprint database/tool that sits in between MusicBrainz and Discogs. That way hopefully the community can standardize and quantify some of this info that only lives ad hoc in Steve Hoffman forum threads or partially on sites like https://dr.loudness-war.info

Working on https://gametje.com (a Jackbox games competitor). Been working on the Android TV app lately. Will probably start creating a new game next week with acronyms similar to the old game Acrophobia from the late 90s/early 2000s.
