Who is who
👋 I am Grégory Saive, and I live in Spain; I am a software artisan whom stepped into
software in 2002. I have a great deal of professional experience to offer with regards
to software development and for every step of the lifecycle of your software project!
🧐 I have previously acted as a Head of Development for NEM Foundation, as a Blockchain Lead in Web3 for dHealth Foundation and as a CTO for UBC Digital Magazine. I have also worked closely with teams building on top of Solana, TON, Cosmos and more technically with integrations of custom consensus protocols based on CometBFT / Tendermint. All the while, of course, continuing to grow my technology skills. My latest research includes:
✅ Development of a Framework for Parallel Runtime of Tendermint Consensus (cometbft) ;
✅ Deployment of COSMOS/Solana/TON/Ethereum blockchain networks (historical data migrations) ;
✅ Deployment of next-generation blockchain networks (dual blockchain migrations) ;
✅ Distributed and modular patient identity using BIP32 algorithm and key derivation ;
✅ Verifiable end-to-end encrypted (E2EE) messaging and identity using key derivations ;
✅ Distributed rewarding mechanism for e-fitness platforms including Strava (health2earn) ;
✅ Wallet-, Explorer-, Monitoring software and software development kits for blockchain networks ;
✅ Generative AI software (NLG) for kids using our software SaaS in schools ;
✅ Expert SaaS software developer with over 21 years of experience in the industry ;
✅ Published Author in the iX Magazine by Heise with "In Signo Veritas" ;
✅ Published Tutor for ECCouncil Learning with "Hands-On Cryptography with C++" ;

Our work
As a team, we have contributed to the many open standard definitions published by @eVias over the past years, including but not limited to NIP13 for defining Security Tokens and NFTs with Symbol from NEM, NIP6 for using Hierarchical Deterministic Wallets with Symbol from NEM and NIP16 which focusses on providing a smooth Components experience when working with Symbol from NEM and compatible networks like dHealth Network.
Note that the above open standards have all been *used* in production with dHealth Network from 2021 to 2023. We put our focus on qualitative and innovative development skills and our headline is that **open source is a beautiful way to collaborate**. Many of our software packages are available at Github. That is because we believe in an open access to innovation.
Our latest products and editorial works include:
