What I'm looking for

I am looking for opportunities that foster growth, innovation, and collaboration in technology.

I am an Electronic Engineer with 4 years of experience in systems integration, specializing in MuleSoft and API-led architecture. My background spans the finance and construction industries, where I have successfully delivered scalable and secure integrations across enterprise platforms like Salesforce, NetSuite, SAP, and various AWS services.

Currently, I work as a Software Engineer at Recurly, where I participate in the architecture design and enhancements of MuleSoft applications. I also support MuleSoft integrations, working on CH 2.0 and integrating with systems such as NetSuite and Google services like BigQuery. My previous role as a Full Stack Developer at Holcim ADC involved designing and developing MuleSoft APIs, implementing CI/CD pipelines, and ensuring best development practices.

Throughout my career, I have focused on delivering reusable integrations and enhancing internal MuleSoft products. My technical expertise includes working with AWS cloud solutions, NodeJS, and various web application frameworks. I am passionate about leveraging technology to create efficient and effective integration solutions.
