Case studies

Architecture and AI first; engineering projects show the depth behind them. Each case states my role, the decisions and how results were verified.

Architecture & platforms2026

Modular CRM/ERP platform, designed and built solo with AI agents

A modular CRM/ERP designed to replace an off-the-shelf portal at a medical-equipment distributor. I did the analysis, architecture, implementation and hardening; AI coding agents wrote most of the code under my control. Deployed on the client’s server as a pilot.

Bitrix24 recovery: a silently stopped 1C integration and data nobody trusted

I took over a Bitrix24 portal that several vendor teams had worked on before. The exchange with 1C had silently stopped. I audited it, found the root causes and put the data back in order — AI agents wrote the audit scripts and code, decisions and production steps were mine.

AI agent platform: agents plan, code and review — a human approves merges and production actions

A self-hosted platform where AI agents turn a task into a reviewed pull request. An independent reviewer model (LLM judge) gates quality, a private RAG gives agents project memory, and production actions go through human approval.
