# about

Hi, I'm Jossué! I'm a Computer Scientist graduated from the Faculty of Mathematics and Computer Science at the University of Havana. I currently teach programming while researching in theoretical computer science, particularly computational complexity, formal languages, and Boolean satisfiability.

At the same time, I have nearly three years of experience building software, currently working as a Full-Stack Developer at AIKoders LLC, working on SaaS products, web applications, automation, CI/CD, and mobile development.

# doclib
A blazingly-fast, memory-safe, tag-indexed shelf for books and articles.

[active] [2026] [Rust · SQLite]

A tag-indexed document library for books and articles, built as an alternative to organizing knowledge through traditional directory trees.

Written in Rust, doclib combines full-text search, content-addressable storage, metadata resolution, local caching, and eventually consistent replication across multiple storage locations.

# hulk-r
A compiler for a type-safe, object-oriented programming language. Built in Rust.

[active] [2025] [Rust · LLVM]

A compiler for HULK (Havana University Language for Kompilers), a didactic, type-safe, object-oriented and incremental programming language

Made in Rust, targetting LLVM intermediate representation. A Project focused on language design, parsing, semantic analysis and code generation.

# eagle-chat
A chat messaging application with a decentralization and freedom premise

[active] [2025] [Go · Docker Swarm]

A decentralized chat application built as a distributed system, designed around secure communication, identity management, and reproducible infrastructure.

Developed in Go and deployed on Docker Swarm, EagleChat explores service orchestration, overlay networking, PKI-based authentication, and distributed system management through a CLI-driven infrastructure layer.

# sem-classifier
AutoML framework and model implementations for semantic segmentation of SEM images of materials

[active] [2026] [Python · PyTorch]

An AutoML pipeline for semantic segmentation of Scanning Electron Microscopy (SEM) images, designed to explore and evaluate different model architectures and data augmentation strategies.

Built in Python, the project combines automated k-fold experimentation with dedicated Swin Transformer training, learning curve analysis, early stopping, and reproducible evaluation pipelines.

# faster-cli
Measure the speed of your internet connection from the terminal. Inspired by fast.com

[active] [2026] [Rust · CLI]

A command-line tool for measuring internet connection latency, download speed, and upload speed directly from the terminal.

Written in Rust, faster-cli focuses on a responsive terminal experience while remaining script-friendly, with structured JSON output, interactive live measurements, and predictable behavior when used in shell pipelines.

# portfolio
This site. A tmux session that happens to be a resume.

[wip] [2026] [Rust · Leptos · WebAssembly · Trunk]

A terminal emulator that renders my career.

Scrolling replays a tmux session: commands type themselves, panes split,
output lands. Reach the bottom and the prompt goes live — the scroll script
and your keystrokes run through the exact same command registry.

Every word of content lives in `content/*.toml`. A build-time xtask parses
it, validates it against the shared schema, and bundles it into a single
`content.json`. No prose is compiled into the binary.
