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.
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.
Manufacturing & warehouse portal for an endoscope production line
Deployed and upgraded a modular .NET / Blazor portal next to the existing Bitrix24 CRM, and migrated full bills of materials from Excel.
Firmware for an endoscopic medical device, IEC 62304-ready
Audited and hardened AVR firmware of an endoscopic medical device, then prepared the software documentation required for device registration.
ESP32 devices: voice assistant, motion gloves, USB printer emulator
A series of ESP32-S3 devices from schematic idea to working firmware: offline wake word, wireless sensors, and USB protocol emulation.
Wireless keyboard firmware: 50 ms → 0.1 ms latency
Split keyboards on ZMK/Zephyr with an e-paper dongle: profiled and removed input latency, added live typing metrics.
