Experience

ERP System for Railway Logistics Company

This project involved integrating the company’s core business processes into the ERP platform, starting from a price/margin calculation and ending with financial reports, delivery notes, and invoices. This enabled real-time tracking of up to 5,000 railway carriages for clients and internal purposes.

I was a back-end developer and a team lead of three developers.

Finrazor | Independent Crypto Market Navigator

A crypto market project with three main parts: interactive financial charts, market-related news, and a blog platform.

I solved numerous key challenges, including real-time market data and related news tracking (Twitter, RSS/Atom, and Telegram), ML-based news clusterization, and sentiment analysis.

Lambada Market | Handmade Crafts Marketplace

A marketplace for handmade and vintage goods. It's like etsy.com for the local Russian market.

We built the MVP and launched the project to production in six months. I was a back-end developer and led a team of four developers.
