Stuff I've built so far @Holdex, mostly in Golang:
- The GraphQL API - Business logic using DDD, CQRS, and Event Sourcing patterns - Events streaming between microservices using gRPC - Background data aggregation processes backed by Postgres/SQLite/Redis - Background email notifications schedulers - Authentication system + OAuth2 and OpenID Connect for 3rd parties to integrate "Login with Holdex". - CI/CD pipelines using Google Cloud Build, Docker and Docker Compose - Background processes to retrieve and aggregate Transactions & Events data from the Ethereum blockchain
Also, Smart Contracts for Tokensales/Airdrops using Solidity.
- Learned Golang and started using it as the main programming language for writing a more robust and elegant code - Built GraphQL/gRPC/REST APIs for freelance projects in Golang - Learned new patterns like DDD, CQRS, and Event Sourcing which improved a lot the way I write code and approach business logic problems - Written an Event Sourcing library in Golang which uses PostgresSQL as an EventStore
- Co-founded Elysio Digital Agency with my 2 best friends: a designer and a frontend dev - Worked on freelance projects like Online Marketplaces and E-Commerces mostly using PHP and the Laravel Framework
