Welcome! I am Yuri Zamyatin,
Full-Stack web developer.


Profile Image

I am passionate about building software that makes lives around me more comfortable. A fan of performant, scalable, reliable and interoperable solutions built via simple modern instruments and distributed as free software.

As a Full-Stack developer, I have Frontend and DevOps knowledge, although my strongest skills and interests are in the Backend field. Currently keen on Node, Typescript, SQL, Linux and architectural patterns.

My greatest strength is my will to challenge the suboptimal status quo.

Featured projects


A new approach to the permission management.

hierbac is a role-based access control system accessible via HTTP interface. Its key principle is that user can grant a subset of their own permissions to someone else. All roles are defined by the grant hierarchy, not by unique admins.

Each user has a list of identities representing them on different platforms. This allows hierbac not to roll out authentication despite being a multi-platform system.

Service works as an open platform where anyone can create realms, permissions, users and other entities.

Coming soon


Personal financial data model & tools.

This repository contains the SQLite schema and scripts to handle financial data. It takes a generic approach to assets, transactions, balances and other things providing heavy automation capabilities, extensibility & deep analysis opportunities.

By publishing this I would like to share some experience on the subject and look for further ideas.

For the last couple of years focusing on my main job. There were some interesting entries before, however they do not meet my current quality standards. Hopefully this will change someday.
