I'm a senior backend engineer specialized in Rust, Python, AI, blockchain, and distributed systems. With over 15 years of experience, I've contributed to open-source projects, built trading, distributed and AI tools, and designed robust peer-to-peer architectures. you can check my personal web, 8 years coding in Rust or more. 20 years coding in Python (from the University) and other languages (Java, Elixir, C++, etc)

• 🧠 (zkMiniVM, zk_docsim) – Starting to play with zero-knowledge, mini virtual machine built in Rust for zk-proof and AI-LLM experimentation .
• 🔗 P2P Voting System – A decentralized voting system using libp2p and a custom consensus layer.
• 📈 Crypto Real-Time Tracker – A WebSocket-based tracker for live BTC/ETH price feeds with sled database integration.
• 📚 [SimpleDBNN](https://github.com/carlosb1/simple-db-nn) – A pluggable embedding-backed k-NN vector database built on LMDB + Arroy.
• 📚 [BoeSearcher](https://github.com/carlosb1/projects-rust/tree/main/search-example) – A search website for BOE (Official Spanish documents) via embeddings and in an near future LLMs.

• 🛠️ summarization-editor – Web tool to refine AI-generated transcriptions with edit tracking and playback.
  Being cleaned up and documented for broader use.

• 🛠️ examples-c14 – Experiments in C++ 14 Personal lab to test ideas and patterns.

• 🛠️ infra-projects: django-rds-celery-mlflow – A complete stack setup with Django, RDS, Celery and Docker.
  Currently improving Docker setup and infra automation.

• 🗃️ upc-aidl-19-team4 – Final university project involving Android, AIDL, and inter-process communication.
  Archived, but kept for historical and academic context.

• ✅ workshop-distributed-systems – Hands-on material to learn how to build distributed systems in Rust.
  Used in internal workshops and now shared publicly.

• 🗃️ Publisher/Subscriber Library – Tokio-based pub-sub communication example in Rust.

• 🗃️ Serverless Workshop Examples – Demonstrations used for serverless architecture workshops.

• 🗃️ Bot News Detector – Crawls news and detects fraud-like content.

• 🗃️ Java Clean Architecture – Demonstration of clean architecture principles in Java.

• 🗃️ Siamese Neural Network – Model for image-based identity matching using Siamese architecture.

• 🗃️ CBIR Search System – Content-Based Image Retrieval system using VGG16 + Flask.

• 🗃️ Old Rust Projects – My drawer of past Rust experiments and learning exercises.

Ofc, I have a lot of projects, like katas, ideas for different languages (kotlin, elixir, python, etc...)

• I worked in more projects, but these (right now) is my main stack.

I try to contribute when I can (though time is limited!).
Some examples:

• tokio contributions
• kornia (computer vision)
• nix-rust ecosystem
• meilisearch

I've helped and participated in several tech communities and open collaboration spaces:

• Akasha Hub Barcelona Rust Bcn
• Software Crafters Barcelona video
• Labdoo (tech for education)

• 🌐 LinkedIn
• 📬 Email
• 🧠 Blog: carlosb1.github.io

I'm currently open to opportunities as a Rust backend engineer, especially in Web3, blockchain infra, or peer-to-peer systems.
