Lev Nemirovskii

With 15 years in IT, I went from web developer to CTO. I specialize in managing cross-functional teams, development, analytics, DevOps, and architecture. I launched high-load projects from scratch with 20k+ RPS. In my spare time, I teach at HSE, speak at IT conferences, write articles, and mentor. My passion for travel, motorcycles, and music complements my technical activities, helping me maintain a creative approach to solving complex problems.

Personal projects you can explore through code, demos, and architecture notes.

ZenMoney Export

A tool to export and sync data from ZenMoney into a personal database.

As a ZenMoney user, I missed advanced financial analytics and the ability to experiment with ML for personal finance analysis.

ZenMoney Dashboard

A Grafana-based dashboard for visualizing and analyzing personal finances from ZenMoney.

I needed a BI tool for financial analysis without extra complexity, so I went with a familiar choice: Grafana.

Observability Pet Projects

Docker Compose configs and code samples for observability setup (metrics, logs, traces) in Laravel, Go, and Node.js projects.

I often talk about observability, but materials were scattered. I wrote an article and built a repo to show it is simple and very useful.

ZenMoney Go SDK

A Go SDK for the ZenMoney API.

While exploring the ZenMoney API, I found the docs were off and the structure was complex. I needed a tool that captures these quirks and serves as living documentation.

Nginx Proxy Docker

Quick setup of a reverse proxy with SSL support in Docker.

An older project I update from time to time to solve a simple task: nginx with SSL on a VPS for quickly hosting small projects.

Auth Service Example

A full authentication and authorization example for microservices using Ory Hydra, Ory Kratos, and Apache APISIX.

I wanted to share experience with authN/authZ in microservices. I built this example and wrote an article, and also dug into Apache APISIX as planned.

Before 2020 — the path to CTO

Ten years of hands-on work shaped every decision that followed: freelance websites, my own web studio, and the first serious e-commerce load. The habits stayed — standardize the stack, automate releases, and build teams around clear processes.
