Standing on Shoulders: The Stack That Makes Floci Start in 24ms

A dev.to write-up on the open-source stack behind Floci's ~24 ms startup: Netty, Vert.x, Quarkus, and GraalVM Mandrel, and how years of production hardening in those projects make it possible.

Why Floci Is Built in Java (and Why That's the Right Call in 2026)

A dev.to write-up on why Floci is built with Java 25, Quarkus, and GraalVM. A choice driven by hard constraints (cold start, memory, single binary) rather than preference.

The Floci Philosophy: Stay Tiny, Feel Like Real AWS

A dev.to write-up on the design philosophy behind Floci: how it stays tiny while still behaving like real AWS, instead of forcing you to choose between fast-but-fake and heavy-but-faithful emulation.

Floci Storage Modes: Pick the Right Trade-off Per Service

A dev.to write-up on Floci's four storage modes (memory, hybrid, persistent, and WAL), how to choose the right durability versus speed trade-off per service, and why none of it sits behind a paywall.

Floci on dev.to: the Short Version

A shorter, community-friendly intro to Floci that I published on dev.to, the fast, free, zero-auth AWS emulator. Cross-post with links to the original and the full deep dive.

Don't Ask, Don't Poll: Just React to Your Database

Contributing to the Data Streaming Revolution: Debezium

Sharing my experience contributing to Debezium, the leading open-source platform for Change Data Capture (CDC), and its impact on real-time data architectures.

My Journey as a Linux Admin Instructor (2007 to 2012)

Reflecting on my years as a Linux Administration instructor at Fundación Código Libre Dominicano, where I helped train the next generation of sysadmins in open-source technologies.

Floci: Local Cloud Emulators for AWS, Azure & GCP

Floci is a suite of fast, free, MIT-licensed local cloud emulators for AWS, Azure, and GCP. Built with Quarkus and GraalVM, each starts in ~24ms and idles around 13 MiB, with no accounts, auth tokens, or usage limits.

Introducing Floci: The Fast, Free, and Open-Source AWS Emulator

A deep dive into Floci, a lightweight, zero-auth AWS service emulator built with Quarkus and GraalVM that starts in 19ms, uses 42 MiB at idle, and passes 100% of AWS SDK compatibility tests.
