Full-stack Developer  •  Applied Blockchain (consultant at ADENTIS Portugal)

Applied Blockchain applies blockchain technology to their clients projects. They offer specialized teams for full-stack web and mobile to build production-ready blockchain applications.

Worked at WyzePay (client’s project). It is a marketplace to purchase coins with discount for spending on their merchants (like a fidelity program): 

- Helped build mobile apps (for consumers and merchants), also an admin website (for the merchants), and their main API for integration (e.g. with the blockchain network). 

- Fixed bugs and gave support to the production environment, dealing with a wide variety of technologies, like: Node.js (for back-end issues), React (for front-end issues), and React Native/Swift/Java for (mobile application issues). 

- Also managed to solve a huge impacting issue related to one internal library written in Swift to integrate with the blockchain network, recovering the mobile app to a whole distribution platform (iOS).

Worked at Reguard Protection (clients project). Which is a marketplace of protection plan providers for home-related items (e.g., Furniture and Mattress): 

- Integrated a SaaS learning platform (TalentLMS) into the merchant portal, for different types of user roles of that merchant. Giving them the ability to provide content sourced by the learning platform. 

- Implemented an internal “2FA“ solution for user data creation/update requests, for higher security and transparency.

- Integrated an email platform (Sendgrid) for better distribution of communication/marketing emails from the platform (for both customer and merchant portals). Also, using designed templates at Figma in the design library held by the email platform service (increasing the user’s experience). 

- Responsible for researching and integrating a chatbot functionality into the customer portal, to give them another channel of guided usage of the platform (at most about the main feature of claiming a product repair under a paid protection plan).

Back-end Developer  •  Deliverful Co

Worked on two different projects: Deliverful and Carmigo.io.

Deliverful's product is a hiring platform for drivers.
- Implemented integration with SaaS products, for customized experiences, such as Argyle (a gateway for employment data).
- Developed a "sync tool" to transfer the data from a NoSQL database (Firebase - Cloud Firestore) to a SQL one (CloudSQL for PostgreSQL). This project used the data coming from its job application surveys, to deliver analytical data to Deliverful's clients.

Carmigo's product is an auctioning platform for vehicles.
- Implemented integration with SaaS products, for customized experiences, such as VIN Decoder service (VIN Decoder and Vehicle History Check), and Black Book service (to offer more precise VIN-specific valuations, Black Book sources, and integrate vehicle history report data).
- Implemented scheduled routines to ensure the correct work of every auction (closing auctions running out of time or having a winner).

Common tasks developed on both projects:
- Implemented the culture of using TDD and also the project organization and design pattern. The development team didn't have applied this method of development until when it was proposed and first attempted.
- Deployed web services as serverless functions on Firebase.
- Applied CI/CD for all the deployable projects (Back-end and Front-end).
