He worked on iOS development, system administration, UX design, and video and audio content production, and eventually decided to focus on web development.

Diskreta | An E2E Encrypted Chat System
An end-to-end (E2E) encrypted chat system based on MongoDB, Express.js, React, and Node.js, fully developed in TypeScript from scratch, optimized as PWA.

The clients generate deterministically, using a 24-word mnemonic, a pair of RSA keys, and only the public key is sent to the server. Users then encrypt the messages with their recipient RSA key and store the chat history in their device, which is encrypted using a military-grade encryption Advanced Encryption Standard (AES) algorithm and the SHA-512 mechanism for digesting their username and password as the key.

The main challenge has been the password recovery system. Without an email address to prove the user identity, the only way was to save the digest in local storage, encrypted with the generated public user key. If users still have access to the mnemonic, they will be able to regenerate the old private key, decrypt the old digest, recover the data, insert a new password and update the server with their new credentials, and re-encrypt the data with the new digest.
