Senior Blockchain Developer

Hello there,

I am Grégory Saive, and I am a software artisan whom stepped into software in 2007. I offer a great deal of professional experience in software development and for every step of the lifecycle of your software project!

I think that I stand out from the crowd with my leadership skills, my enthusiasm for software development and my 19-years experience as a software engineer which led me through using many different technologies.

Find attached a quick overview of technologies that i used or developed before:

✅ Node.js/Laravel/Golang services, SSR, SSE, Websockets APIs, RESTful APIs. Examples: pacnem.com, dings.app

✅ Modern Javascript/Typescript with active interest in Web APIs, Speech API, Websocket API. Examples: public js libraries and several frontends including dings.app.

✅ Previous work in EdTech, FinTech, DeFi, NFTs, Tokenization, eLoyalty, MLM, Play2Earn. Co-inventor of "Health2Earn" for dHealth Network.

✅ Managed several different AWS/GCP/Docker container clusters for microservices, mostly for Web3 projects including a "health-2-earn" protocol implementation.

✅ Developed, maintained and monitored a CometBFT production fork which sustained 150K TPS with 2M active users at peak.

I am available to start a few days after agreement. I am a very professional and experienced software developer and need a little less onboarding usually, due to my deep knowledge with many different technologies that I have come across during my career.
