Senior full-stack engineer specializing in scalable fintech and cloud systems, from frontend architecture to performance.

What I'm looking for

I’m looking to build scalable fintech/SaaS products with strong frontend architecture, measurable performance gains, and reliable cloud deployments on AWS/Azure. I want an agile team that values maintainable code, testing, and mentorship.

I’m a Senior Full-Stack Engineer with 7+ years of experience building scalable fintech and SaaS applications. I focus on frontend architecture, application performance optimization, and cloud-based systems across AWS and Azure environments.

In my recent role at Racklify, I built and maintained full-stack applications with React, TypeScript, Python, and Go for enterprise financial systems. I modernized legacy platforms with reusable frontend components, cleaner backend architecture, and performance improvements through optimized REST APIs and PostgreSQL query tuning.

Earlier, as a Frontend Developer at Predictiva S.A.S, I developed responsive web applications using React and TypeScript, built reusable UI components, and improved platform usability. I also optimized PostgreSQL queries and data workflows to boost reporting and transactional system performance.

I started as a Junior Software Engineer at Lifti, where I delivered cross-platform mobile and web experiences with React Native, React, and TypeScript, and built backend integrations using Python.
