I build APIs, data workflows, and backend systems that power real-world platforms.

About

Backend systems with product context

I’m a backend-focused software engineer specializing in TypeScript systems, distributed workflows, and data-driven applications.

At Victaulic, I’ve worked on modernizing legacy internal platforms into scalable services using NestJS, Angular, SQL, and Azure. This included refactoring tightly coupled systems, improving background processing reliability, and supporting integrations across teams.

In parallel, I’m building AISeq, where I lead the architecture of a wellness genomics platform using TypeScript, PostgreSQL, Prisma, and clean architecture. This includes designing versioned data models and workflow-driven APIs.

I focus on backend systems involving APIs, workflows, integrations, and data platforms.
