Interpreter for business application

Interpreter for business application

Competencies: Virtual Machine, Algorithm Development, Compiler, Software Architecture, Software Development, WebAssembly, Rust

The project is intended to simplify business calculations and is built on its own programming language. On the project we mostly worked on a parser and interpreter. One of the important tasks was implementing API and business logic for the generation of tooltips in the expression editor. At the initial stage we used lalrpop parser. It's a good parser for syntactically correct code and it is very hard to use for syntactically incorrect code.And the task with hints is precisely related to incorrect expressions. In the first iteration, we bypassed the limitation through String based error analysis.
The project has a layered structure and the interpreter is separated into its own layer. Parser and interpreter are on their own layers.
The following crates were instrumental in the implementation of the project: lalrpop (parser generator), logos (lexer generator), bumpalo (bump allocator), expect-test (snapshot testing).
The application is compiled in WASM. And the expression editor uses the API WASM module for hints. APIs are provided for use by the graph content expression editor.

Microservice Development

Microservice Development

Competencies: Neo4j, Amazon Web Services, Google Cloud Platform, Rust, Microservice

A solution included initializing a Neo4j database with values from an Amazon S3 bucket.
In addition, we conducted research on other databases and potential solutions for implementing the desired behavior.
Our task was to explore possible ways to initialize a database with values from a remote resource.
It included investigating how to retrieve the values, how they should be transformed, and how to deliver all the necessary values from one resource to another.

Schnorr signature

Schnorr signature

Competencies: cryptography, rust, fuzzing

This Rust library provides an implementation of Schnorr signatures based on the curve25519_dalek library. Schnorr signatures are a cryptographic primitive that provides a secure and efficient way to prove the authenticity of a message or transaction. They offer several advantages over other signature schemes, including compactness, resistance to side-channel attacks, and simplicity.
Key Pair Generation: Key Pair Generation: To create a Schnorr signature, user generates key pair consisting of a private key (xi) and a corresponding public key (Xi), where Xi = xi * G and G is a known generator point on the elliptic curve.
Signing: The signing process involves the user combining his private key, public key, nonce and the message to create a signature. Verification: The signature can be verified using the public key, public nonce and the message. If the verification equation holds, the signature is considered valid.
