The thing on the mainnet I have is the Vote Coin project. It is open standard and open source implementation on onchain voting solution. Onchain community (for example DAO) can ask a question through the blockchain by writing specific json with their asa with self sign tx, any community members can cast a vote, there is also implemented encrypted voting so that the vote casts are not public until the dao publishes the encryption key, there is also voting delegation so that the onchain community members can delegate their voting power to other accounts so that the voting is in long term efficient.
I also have created AWallet, where i tried to make the official algorand wallet (now Pera wallet) to become open source (after one week on mainnet I suceceded 
). Interesting thing is that this wallet is still the only one which supports rekeying of multisig accounts, is using public set of nodes so that person can select one he trusts, or it is the only place where person can make his account to online state.
I am main coder / CTO of Aramid finance - EVM 2 AVM bridge. We have passed the audits, and launching mainnet soon. We have some delays because we need at least some VC funding so that we dont start with dry accounts. Daniel was at ETH Denver last week. https://www.youtube.com/watch?v=5Aw3osxi2BI
I am main algorand coder for Diatomix. Impermanent loss solution. Basically you can profit from AMM moves and stick the investment to dollar value. Verum capital received VC funding and raising now for second round. The project is deployed to testnet for closed group.
I submitted to the GHH3 project stabilitas - National stablecoins minting by smart contract with oracle from ECB, but for some reason it did not make it to top 4 projects. Chat project is according to judges better. (Or my conspriracy theory algorand foundation did not want to do nowadays anything to do with stablecoins because of the Gary Gensler)
I was overall winner of swiss blockchain hackathon with project DREM - Decentralized real estate marketplace. I have not found any VCs yet to invest into real estates. But i am developing it slowly in my spare time. The vote coin or stabilitas are basically support projects with my long term vision.
I was in the past president of the exchange chamber at regulated commodity exchange (CEB), later I was profitable prop equity trader doing arbitrage and market making in one of the largest investment banks in eastern europe (Wood&Co), later i created data center for EP holding (EPC), later i have created covid testing app which has tested something like 1 mil people in EU.
I was winner at few hackathons… For example eID hack, EU vs Virus, HackujStat, Encode hack, SB Hack, El salvador bitcoin bankathon, DAO hack, Algo hackjam, Greenhouse hack, … With the vote coin I was in Encode accelerator.
What I am the mostly grateful to the AF is that I am one of the relay node runners, however I believe that the relays should be in open competition who provide better services, not selected in the competition by central authority.
