Senior Fullstack & Infrastructure Engineer

Fabio Cingottini

Open to contract & permanent

I build the product and the cloud infrastructure that runs it — from React and TypeScript apps to the Kubernetes, Terraform, and AWS underneath. Nine years turning complex systems into things that ship, scale, and stay up.

Let's Talk

What I Do

Infrastructure & Platform

I build and own the infrastructure under the product — Kubernetes, Talos, Terraform, AWS, and Linux. Zero-downtime cloud migrations, infrastructure rebuilds across 15+ environments, and platforms engineered to stay up under load.

Fullstack Development

Nine years of TypeScript and JavaScript across the whole stack — React and Next.js on the front, Node.js, Bun, and Rust on the back, with databases, message queues, and containers in between.

Architecture & Scalability

I design systems built for growth: caching strategies serving 10,000+ requests at peak with minimal cost, and applications optimized to absorb 2x traffic increases without downtime.

Technical Leadership

I've led and mentored engineering teams of 5–8 through example-driven mentorship, staying hands-on in architecture decisions while shipping platforms that scaled from startup to enterprise.

Selected Work

Brokerage & Algorithmic Trading

Fintech · Current

Building the infrastructure and backend services for a financial brokerage and algorithmic-trading platform — Kubernetes and Talos clusters, containerized deployments on AWS, and high-performance services in Bun and Rust, with contributions upstream to the Bun runtime.
