At the end of 2021, me and my 2 cofounders started building DogPay, a Stripe-like system for crypto payments. After movements in the market, we pivoted to build Karamelo, the MetaMask for Gamers. It was a web3 wallet designed for the gaming ecosystem that has a built-in solution for lending NFTs (without the need for a collateral or requiring any new integration by the game). Being the Technical Founder, I was responsible for (1) implementing and deploying our product, (2) setting guidelines for a secure system, using both web2 and web3 architectures, (3) all activities related to engineering and technical insights.

As a Lead Software Engineer for a Monetization Tech squad, I was the owner for the technical deliveries made by the squad (end-to-end), helping design and deliver our LiveOps tools. Also, I helped define cross-squad practices, to be used by the whole vertical. Additionally, I was the owner for the mobile area of the Monetization Tech vertical. Being responsible for the mobile guidelines, designs and deliveries of our vertical.

Initially, I worked on the Tools team, which was responsible for creating and managing the SDKs that are included in each of our games in production, such as, Ads Mediation, Analytics, Purchases, Notifications, Networking, etc. As a Software Engineer for the Tools team, I was the owner of both Jenkins and Android SDKs. Also I was a general contributor and maintainer, proposing and implementing SDKs and internal tools to be used by the whole company. We were responsible for the end-to-end design and development: backend, internal frontend, SDKs, infrastructure (via terraform, supported by the SRE team), and build pipelines.After some internal rearrangements, I became a Software Engineer for the Monetization Tech initiative, where we focused on designing and developing tools aimed on improving the LiveOps and Monetization of our games.

As an intern for the Tools team, I specified and created unit and integration tests for both iOS and Android SDKs. Also, I helped with the maintenance for SDKs developed internally.
