What I'm looking for

I’m looking for a backend role building reliable, secure Node.js systems—especially fintech/payment solutions—where I can design scalable event-driven architectures, own RESTful APIs, and collaborate with cross-functional teams.

I’m a back-end engineer focused on Node.js, delivering reliable, efficient, and secure systems that meet business needs. I specialize in building ACA-ready, high-quality backend solutions using modern frameworks and tools.

As a Senior Node.js Developer (03/2025 – present) at BitBreeze, I lead backend development for fintech/payment solutions, with an emphasis on scalability and multi-tenant architecture. I’ve designed secure payment processing flows and integrations with Stripe, Authorize.net, and NMI, while improving reliability through event-driven patterns, Nest.js/Express.js, and message queues (RabbitMQ, BullMQ).

Previously, as a Middle Node.js Developer at SMARTSOFT LLC (03/2023 – 03/2025), I implemented RESTful APIs, system architecture, and CI/CD pipelines, leveraging Clean Architecture, microservices, and event sourcing. I also bring strong DevOps and code-quality habits—Docker/Kubernetes, Prometheus/Grafana monitoring, Swagger documentation, Git-based workflows, and tooling like ESLint/Commitlint/Prettier—having started as a Node.js Intern and Junior/Middle developer across multiple teams.
