Igor portrait

I automate processes, connect systems, and stabilize complex projects.
Possibilities begin with your idea. I work through legacy systems, CRM/ERP, 1C, websites, bots, and internal portals. I take on bold challenges and turn complexity into working products that can keep growing.

My Experience

August 2024 - Present

Senior Backend / Integrations Engineer - DataSoft

Connected 6+ enterprise systems into one 1C ↔ Web ↔ CRM circuit. Added Redis caching (×4 speedup), removed race conditions, applied AI agents to development workflows, and accelerated MVP delivery: in some scenarios to 1-5 days instead of 3-4 months.

July 2019 - April 2023

Technical Lead / Lead Fullstack - Prime Systems Group

Recovered a critically unstable Laravel project and moved it into a controlled release cycle. Stabilized WebSocket chats and C++ agent communication, reduced production chaos, and helped the project grow to ~$1M in profit.

May 2016 - May 2019

Fullstack Developer - Innova Systems

Built an ERP module with roles, cost accounting, and transparent order flow. Reduced production estimate turnaround from about 10 days to 2 days. Also handled R&D: Web3 prototype, latency, and concurrent transaction testing.

February 2013 - April 2016

Web Developer / System Analyst - Alterna

Removed order chaos and Excel macros: built a web cost calculator, warehouse accounting, and first REST integrations. The team gained transparency over estimates, materials, and statuses instead of manual reconciliation.

How I approach complex systems

From chaos to a working system

I show how I work through legacy, manual processes, and scattered integrations: find bottlenecks, shape a clear architecture, and turn a troubled project into a system that can keep growing.
