I design and build complex business systems from scratch.

Business Systems Architect and Fractional CTO. I design the architecture of processes, integrations, data and infrastructure and carry it through to working systems — from CRM/ERP and web platforms to offline apps and AI automation. I choose technology to fit the business goal.

Positioning

I work at the intersection of software engineering, business operations and AI automation. For 12+ years I have built systems that connect sales, procurement, warehouse, documents, finance, communication and management analytics.

Architecture is my core skill. I get into the business process, find the bottlenecks and design the whole system: business applications, integrations, the data model, access rights and infrastructure. Then I take it all the way to the users and make it work in daily operations.

I build complex systems from scratch around the processes of a specific business. For example, a quality control platform for a large construction business: a web app and an offline app for inspectors on sites without internet access, with roles and access control, contractor data isolation, an audit trail and documents in the client's own forms.

A broad technical outlook helps me fit the technology to the problem, not the other way round: sometimes the answer is an AI agent with access to CRM and ERP, RAG over internal handbooks or call quality control; sometimes it is data extraction from messy sources, offline sync or a careful server migration. For me technology is a means to a business goal.

Where I Fit

I am useful when the problem is not a single screen or script, but the operating system around the business.

01

Businesses that need a complex system from scratch

Spreadsheets and off-the-shelf tools no longer cope: you need your own data model, roles and permissions, documents in your own forms, field work without connectivity, and an architecture that can grow with you.

02

Companies choosing or migrating CRM/ERP

You need someone who has already lived through AmoCRM, Bitrix24, MoySklad, ZoHo, Odoo and the tradeoffs behind each choice.

03

Teams adding AI to real workflows

You do not need an AI demo. You need agents, extraction, summaries and QC connected to actual systems and permissions.

04

Founders without a full-time CTO

You need senior technical judgment, vendor decisions, roadmap ownership and implementation oversight without hiring a permanent executive yet.

What I Build

Hands-on architecture and delivery across business systems, integrations, data, infrastructure and AI workflows — from design to a working system.

01

Business Systems Architecture

CRM, ERP, WMS and custom platforms designed around the actual flow of deals, orders, stock, documents and field work.

  • Target architecture and process map
  • CRM/ERP selection and migration, or a custom platform from scratch
  • Roles, permissions, data model and audit trail
02

Integration & Automation Layer

Python/FastAPI services, webhooks, background workers and APIs that make disconnected tools behave like one operating model.

  • Bitrix24, Odoo and external API bridges
  • Document, payment and shipment workflows
  • Reliability, monitoring and access control
03

AI / LLM Business Tools

Practical LLM systems for internal teams, built around a specific business task: agents, RAG, transcript analysis, structured extraction and quality checks.

  • Tool-use agents with role-based access
  • Meeting summaries, action items and QC
  • Parsing email, WhatsApp, PDF, OCR and voice notes
04

Fractional CTO & Technical Operations

Senior technical leadership for companies that need decisions, roadmaps, infrastructure and vendor management without a full-time CTO hire.

  • Build-vs-buy and vendor decisions
  • Infrastructure, migrations, backups and security
  • Delivery ownership from idea to adoption

Selected Cases

The kinds of systems I work with, shown through projects: platforms built from scratch, CRM and customer journeys, business system integrations, AI products, infrastructure and my own e-commerce business.

Large construction business / architecture and delivery

Construction quality control platform from scratch

A construction quality control system for an industrial site: from a request to inspect works to the on-site inspection, defects and documents in the client's own templates. A web app for the office and an offline Android app for inspectors on sites without internet access.

Web + Android offline work on site
RLS contractor data isolation
KS-2 volumes tracked against the estimate and acceptance certificates
  • A platform for several products: a shared core with roles and permissions, an append-only audit log, file storage and background jobs.
  • Field work without connectivity: the tablet receives tasks in the morning and hands in results in the evening; syncing photos and data is safe to retry, and conflicting edits are resolved.
  • Construction data and documents: contractor data is separated both in the application and in the database; estimate volumes are reconciled with quantities accepted under KS-2 certificates (a Russian standard form); photo-documented defects become documents in the client's templates.

Events / CRM built around the team's process

CRM and participant journey for a festival, from scratch

A CRM built around a festival team's process: registration for several participant types, a journey from application to payment, and a back office where each role sees only its part of the work. Before building, I piloted off-the-shelf CRM platforms and chose a custom system: lighter on resources, with server-side validation of public forms.

3 application types, each with its own forms and rules
Roles data access matched to each job
Email + VK notifications, reminders and messaging
  • A customer journey shaped by the process: multi-step forms, a personal status page with no sign-up, team decisions, approval of participation details, and payment links with payment deadlines and reminders.
  • Business rules on the server: the price comes from date-based tariff tiers, accommodation surcharges and child discounts; accommodation options have capacity limits with no double booking.
  • Team and personal data: each role has its own screen and "waiting for you" counters, payment and sensitive data are kept apart, and staff get VK notifications that contain no participant personal data.

Major Medical Solutions — business systems from zero

Built the operating infrastructure for a European aesthetic medicine distributor: CRM, ERP, WMS, documents, access policies, integrations, internal tools and AI automation.

2021-2025 period
5 system migrations
0 → stack from no IT to operating stack
  • Changing platforms as the business grew: AmoCRM → Bitrix24 + MoySklad → ZoHo Inventory → Odoo Online, with a clear view of the tradeoffs at each step.
  • CRM and ERP as one model: a bidirectional Bitrix24–Odoo bridge keeps deals, orders, payments, shipments, tracking, products, contacts and documents in sync.
  • Event-driven processes instead of manual entry: deal stages move on Odoo events, and document sets are checked and assembled into PDF packages.

Debrif — meeting recording and analysis system

A system for recording online meetings, transcription and summarization that turns conversations into searchable team knowledge.

Chrome extension recorder
RU+EN multilingual scenarios
LLM QC communication analysis
  • Recording meetings where they happen: Google Meet, Yandex Telemost, and Zoom and Teams in the browser, through a Chrome extension.
  • Speech recognition with a choice of provider and speaker diarization; transcript storage and review backed by PostgreSQL, Redis and MinIO.
  • Communication analysis: sales call quality scored on the full transcript against sales handbook criteria.

Agents with access to CRM and ERP

AI assistant and agents for the team

An assistant that answers employees in natural language and chooses its own tools for Bitrix24, Odoo, the procurement service and the sales handbook.

Tool use the agent picks its tools
RBAC role-based access
MCP personal agents for the team
  • Role-based access: sales, procurement, documents, admin and tech support each see what they need; CRM and ERP tools are read-only.
  • Fast answers instead of manual searching: deal status, shipment tracking, margin, purchases, order lines and process questions.
  • Personal agents for the team: each person has their own profile, memory and toolset (CRM, ERP, procurement), connected over MCP.

Supply — supplier offer intelligence

A system that collects supplier offers from chats, email and files, normalizes product names and turns messy offers into a procurement knowledge base.

640+ products
40+ suppliers
multi-source sources
  • Extracting data from messy sources: WhatsApp, email, Telegram, PDF and Excel become structured offers — product, supplier, price, terms.
  • Data quality: validation, synonyms, typo correction and new-product detection before anything reaches the database.
  • Procurement analytics: supplier comparison, price history and trends, Telegram access and an API integrated with Odoo and Bitrix24.

VIES / VAT-helper — VAT checks as a SaaS

A standalone SaaS for checking the EU VAT numbers of counterparties: web UI, Telegram bot and API, bulk checks, monitoring and billing.

VIES official API
PDF confirmations
SaaS productized service
  • Official EU VAT checks through the VIES API, with PDF confirmations stored for paid users.
  • Resilience to an unstable external API: retries, cooldowns, pending checks and background workers without double processing.
  • SaaS security: token revocation, CSRF and IDOR protection, rate limiting and webhook signatures.

Design, migrations, backups

Infrastructure built around business requirements

I design and run the infrastructure behind projects: hosting that meets EU and Russian market requirements, migrations with minimal downtime, backup and recovery, and server security.

EU + RU hosting matched to market requirements
Backups backup and recovery
CVE fresh vulnerabilities tracked and patched
  • Migrations with minimal downtime: moving production systems to new servers and OS versions, rehearsed on a copy, within a pre-planned window.
  • Backup and recovery: backups, a recovery plan and hands-on experience bringing sites and services back up on another provider from backups.
  • Server security: restricted access, firewall, fail2ban, security headers and timely updates for fresh vulnerabilities.
