Software developer building Python/Node microservices and web apps with a focus on scalability and performance.

United States

Message

I’m a Software Developer who designs and builds message-driven microservices and backend APIs for big data scenarios, then brings the work to production with robust testing and CI/CD.

In my recent role, I leveraged Python, Postgres, and Apache Pulsar with FastAPI, Pydantic, and Alembic to develop and maintain dockerized RESTful services, while using Kubernetes and Linux monitoring tools (including Grafana) to optimize performance and stability.

Previously, I developed Node.js web applications with React, TypeScript, and Express, improved automated test suites with Cucumber and Jest, and performed Java performance testing that drove a 20% processing time improvement. I enjoy system design conversations that ensure scalability and reliability for mission-critical projects.
