Игорь Бартенев
Software Architect · Technical Lead
Software architecture, backend engineering, business automation and AI tooling. Industrial engineering foundation since 2013.
Work
Onlihub
Lead Developer · architecture, implementation and delivery
I took technical ownership of a growing platform connecting suppliers, products, marketplaces and fulfillment. The work connected the product lifecycle from catalog and inventory to orders, fulfillment and tracking, with ownership extending beyond individual services.
BOS / Business Operations System
Business modelling and system architecture
I designed and developed a Python operations platform combining dynamic documents, formulas, workflows, communications and employee compensation around a mortgage business. Mortgage workflows gave the platform its first concrete business use case. The reusable core was deliberately designed to support other organizations and processes through configuration, documents and rules.
MCP Hub
Agent infrastructure and integration architecture
I built a working AI operations service that connects agents to project data, logs, communication and tasks through controlled tools and reusable project knowledge. MCP Hub is used in real work: reviewing messages, checking errors, querying project activity and tracing a user journey across systems. The service is currently private, with reusable project knowledge and controlled execution at its core.
Amazon Data / Trends
Data acquisition and processing architecture
I designed and built an Amazon data service that scanned categories across the marketplace, excluding books, and used Elasticsearch bulk processing to identify trends. The service ran for about five months at a historical scale on the order of millions of listings. It supported category-wide trend analysis before the team changed focus and the project was archived.
Liqsale / Daily Snipes
Product architecture and data processing
I built a pipeline that turns fragmented liquidation offers into structured, searchable product listings. Supplier files became listings connected to prices, stock and warehouses, within a product supporting buyers, sellers, chats and orders.
Unity MCP Efficient
Facade design and implementation
I built a compatibility layer that lets agents discover Unity operations without loading every tool schema into context. The published author benchmark of 24 August 2026, against upstream v10.1.0, records 48 → 6 model-visible tools and access to 377 operations. Schema context falls from 23,280 to 915 estimated tokens (characters ÷ 4); this is a documented estimate, not an independently reproduced runtime or cost benchmark.
MySellerHub
Multichannel architecture and integrations
I designed a multichannel model linking listings, warehouses, inventory, orders and fulfillment across external platforms. The architecture supported a connected path from publishing a product in another channel to returning its fulfillment status; the current public product emphasizes Shopify and Amazon inventory.
Onlihub Catalog
Architecture and implementation of the catalog service
I designed and implemented a dedicated Onlihub catalog service with a Rust primary path, Python fallback, Redis caching and Elasticsearch. Search and high-frequency reads gained their own path while transactional storage and business logic retained separate responsibilities.
Manufacturing Engineering
Manufacturing engineering and CAD/CAM
My engineering foundation comes from designing parts, machining operations and the processes that bring products into production. This work established the method I still use: understand the real process, identify constraints and only then design its automation.
ERP / 1C
Business analysis and application development
I built and supported 1C solutions for Ukrainian companies, working directly with customers on accounting, production planning, material consumption and logistics. The experience connected software models to physical stock, money and operational consequences, forming a foundation for later financial and business systems.
Financial Systems
Cross-project financial modelling and integrations
In Onlihub and Liqsale, I built subscriptions, one-time payment flows and transaction models connected to statements, recalculations and business documents. This practice links my ERP background to modern payment systems: financial operations are modelled through explicit states, categories and movements.
Zipurch
Order-data integration and geospatial workflows
I worked on connecting order activity, product information and geographic context in a commerce map. The work brought a geographic view to commerce events, connecting map activity with the underlying product catalog.
Meeting-to-Actions
Speech and agent workflow integration
I worked on a workflow that transforms meeting audio into decisions, action items and tasks in Teamwork through MCP. The workflow connected meeting content to actionable records in the team’s task system.
Local AI / Lightweight ML
Applied research and workflow prototypes
I explore local models and lightweight inference for speech, documents, retrieval and practical automation. A collection of applied experiments informs how I choose models and connect them to useful workflows.
TON Tanks
Product lead, backend and game systems
I helped shape, build and launch a Telegram-connected game with a TON-based NFT economy. The game reached real users and brought product, engineering and launch responsibilities together in one independent project.
Modular Vehicles / Unity
Independent game systems development
I am building and experimenting with modular vehicles, damage, tracked physics and procedural environments in Unity. An ongoing independent development space for testing how physical simulation, modular design and gameplay fit together.
Blender / 3D
Independent modelling and asset preparation
I use Blender to build and prepare hard-surface models, materials and textures for game environments. A collection of independent 3D work that complements my experience with game systems and physical engineering.
Engine Sim Unity Audio
Independent audio tooling
I worked on automated generation of engine audio banks for Unity from a physical engine simulator. A tooling project connecting simulation, automation and game-asset production.
Crypto Trading Terminal
Independent application development
I built a trading terminal combining market data, charting, custom strategies, backtesting and live exchange execution. The application brought strategy analysis and exchange execution into one workflow, including commissions, P&L and recorded results.
