Profile
I’m a software engineer who likes building pragmatic systems. I write Go backends, React frontends, and fullstack products that span web, mobile, and desktop. I’ve been shipping production software for more than 12 years, working with both startups and established companies.
My AI expertise helps companies save significant money by combining paid frontier models with locally hosted ones, or by deploying an open weight frontier model on local servers or in the cloud, cutting thousands of dollars in subscriptions to providers like OpenAI or Anthropic. The same path also guarantees the privacy of sensitive company information, ensuring it is not exposed to other organizations or accidentally shared by the models.

As an Android Developer and Project Manager, I worked on the Welo app, a native Android application written in Java that provides transportation services to users. It incorporates a sharing economy model, allowing drivers to use their own vehicles to earn money by transporting customers who request on-demand services. My primary role involved maintaining, improving, and optimizing both the application and its infrastructure. I implemented a CI/CD process using Bitbucket and Pipelines on DigitalOcean.
