  • Intermediate command line knowledge
  • Used to Debian and Arch machines
  • Cron jobs scheduling and management
  • UFW knowledge
  • Bash scripting
  • Performance monitoring
  • Low level OS knowledge


Minimalism is something that is not usually connected with coding but I like writing concise and highly reusable modules using just the necessary NPM dependencies and relying on the core node.js API when possible.

On deployments I avoid using external dependencies such as Redis, Docker, etc. unless it is really needed to scale the service.

Decentralized technologies

  • Decentralized systems theory
  • Knowledge of blockchain and alternative decentralized ledgers
  • IPFS
  • OrbitDB decentralized databases



A C++ implementation of the Paillier cryptosystem including homomorphic operations and some very useful zero knowledge proofs such as set membership and correct decryption.


A fully typed Typescript function memoizator compatible with node.js and browsers alike with a huge focus on performance. Originally created to memoize some DB calls seamlessly without requiring huge packages or dependencies like Redis.


A WIP decentralized cryptocurrency network that makes use of a directed acyclic graph to increase its throughput during activity peaks or adverse network conditions.

It features a nice set of primitives like tokens and data storage that can be accessed and manipulated from smart contracts within the network.

Smart contracts are executed within a custom and very basic VM implementation.

The network can be tested from a graphical UI at
