Senior Software Engineer
I build scalable, reliable software — from geospatial platforms to payment systems.
About
I'm a Senior Software Engineer with over five years of experience building scalable software with TypeScript, Python, React, Next.js, and FastAPI. I turn innovative ideas into deployed, reliable software that meets evolving business needs.
I work across the stack and in the cloud — AWS, Firebase, and GCP — with a focus on Test-Driven Development, CI/CD pipelines, and turning complex requirements into maintainable systems.
