About Alberto

Hello, I am a Senior Fullstack Developer with more than eight years of experience.

Lately I have been focused on helping companies to build and optimize their projects: from creating a Nextjs MVP to optimizing their AWS costs and obtaining more than a 50% decrease of expenses.

From coding a multiplatform mobile app using React Native and Expo to designing an API with Nestjs able to handle millions of requests per hour without downtime and low costs.

I have also worked in amazing projects like finetuning AI models for the backend of an e-commerce SaaS, training custom Llama and Qwen models for the API of a mobile app or building some AI agents with the help of N8N and different APIs.

I think of myself as a builder. I know lots of technologies and I try to use the best for the job. Obviously, I have my favorites, the one I am more expert on; but that doesn’t determine the tool for the job but the clients' requirements and the project specifications!

I am not only interest in building but also in how to build a better team. The best tool for a job is not using Typescript nor Golang.

It is your team.

I focus on being able to explain in non-technical terms to the stakeholders the progress and new features; and I try to get the customer feedback and translate it into detailed tasks for the technical team (think about me as a translator).

Finally, I am always open for a talk about your project. Who knows if at the end we will work together, but no matter what happens both we will earn a new contact for the future, and we will enjoy a nice conversation 😄

If you are more of a techie and want to know some technologies I have used and I love to work on, here you have: Golang, SST, Nextjs, Remix, Typescript, Nestjs, Hono, AWS (Lambdas, DynamoDB, cost optimization), React Native, Expo, N8N, Make and currently I am enjoying a lot Astro. Of course, I have used other technologies, and I can always learn fast any language, but these are the ones I currently use the most.
