Dezinnia
Senior Software Engineer & Solution Architect
April 2015 — Jan 2026- I served as the sole developer responsible for designing and building a web-based ERP system, working directly with the team to gather requirements and define integration scenarios. Over 10 years, I independently developed a robust, feature-rich platform that automates all core business processes—project and artwork lifecycle management, financial reporting, estimates, purchase orders, time tracking, and a customer portal for project requests and approvals.

Datakrat
Software Developer
April 2012 — November 2013- Full-stack web and backend development for retail, POS and mobile devices running WinCE/WinMobile for barcode & RFID identification. Developed a web application for an electronic article surveillance system, including a dashboard for configuring and monitoring components of the system (e.g. lines of check points), updating firmware, handling system events, building statistics and generating reports. Created an inventory tool for barcode scanners running on WinCE for scanning and synchronization with ERP-system. As a part of a team I contributed to the development of an inventory system with responsibilities centered on mobile and backend development. The solution was built for inventory accounting and synchronization between barcode scanners and a backend server, server-side reporting and role-based management.

Featured Projects

Enterprise ERP platform for creative agencies. Complete ownership from business analysis to production. Hundreds of concurrent projects, real enterprise workloads, now a market-ready product. Multi-stage approvals, 34+ reports, 35+ background jobs.
Built over a 10-year partnership with Dezinnia, a Minnesota-based company, helping them streamline operations and optimize business processes.
BestBnB
Airbnb shows 300 listings but won't let you sort by rating and number of reviews. After 50 tabs, you forget which had good Wi-Fi and which had noisy windows. This tool scrapes all listings, lets you sort and filter by what matters, and save notes per listing—so you remember why you liked or rejected each one.
Telepoisk
I've often run into situations where important, practical information can't be "just Googled" or obtained as a one-size-fits-all answer from ChatGPT—especially when it comes to healthcare, travel, restaurants, career decisions, business, or legal questions. In those moments, what matters most to me is real people's lived experience: their discussions, clarifications, nuance, and the freshness of the information. This problem turned into a product. I've built a search engine for hundreds of millions of messages from public and private Telegram chats.
