Where I’m useful
Organisation first, technology second. Conway’s Law: a system reproduces the communication structure of those who built it. This works beyond IT — social forms shape technologies, not the other way around. The steam engine waited half a century until the social form — the factory — was ready to adopt it.
Hence the two vectors of my work:
Business Organisation
How your organisation is structured — that’s how your systems work. What is Organisation? →
State Organisation
How an industry is structured — that’s how the market works. What is State Organisation? →
I’m useful where IT has long become a critical part of the business — yet business and IT still speak different languages.
Industries
Banking
Regulatory burden, high cost of errors, complex approval loops, legacy dependency, and the gap between formal architecture and living practice. I know it from the inside — not from books.
Utilities & Infrastructure
The opposite of banking in financial capacity, yet no less IT-dependent. Long cycles, high inertia, the need to work with real organisational fabric on minimal budgets. City-scale utility billing in production since 1997 — now at Rosvodokanal Group, 10+ cities.
IT & Software
Fragmentation, loss of the cognitive cloud, false modularity, inflated cost of change, and weak coupling between business and IT.
Practice321
I develop Practice321 — a unified practice of organisational resilience. Not three products — one framework in three refractions:
IT-Strategy
The language of digital and operational risk for owners, boards, and CxOs. Not about technology — about dependency, cost, and controllability.
BizOpsDev
A team model where business, operations, and development are not siloed but woven into a living working fabric. In practice since 1990. The longest-running Team321 — 40+ years.
BizOpsVibe
AI amplification of Team321 without losing controllability, accountability, or common sense. Not replacing people — amplifying people.
This is the result of 40 years of work amid continuous Perestroika.
AI-amplified prototyping
Since 2025 — a dedicated practical focus. Tasks that used to take months and a long chain of meaning transfer between analyst, architect, and developer are now solved in days. By 1–3 people with an AI assistant. Including highly regulated domains — banking, utilities.
But a prototype is not production. Sustainable delivery to working operations requires a full Team321 and a managed organisational framework.
Trajectory
Started in a research lab — Laboratory 321 of Superconducting Sensors, Omsk State Technical University. Built an electronic model of a DC-RSQUID, discovered the fractal form of its current-voltage characteristic. Co-author of a peer-reviewed publication in Physica B (1991).
Own businesses since 1990: Lab321 GmbH (Bad Homburg, Germany, since 2020) and Hardsoft321 LLC (Omsk, Russia).
Then — Omsk Bank. 1992–1995. Built one of the first Oracle-based core banking systems in Russia from scratch. Deputy Chairman of the Board. In parallel — developing financial engineering and mortgage operations. Training at Leeds Permanent Building Society and University of Leeds — banking, financial engineering, mortgage.
From 1995 — Compatriots Bank: built the clearing mathematics for net interbank settlements. From 1998 — crisis, wiring buildings, engineering, backup power, warranty maintenance. Ten years of building engineering in parallel with IT.
1996–2026 — Waterman system: city-scale utility billing system. Rosvodokanal Group, 10+ cities.
Sobinbank, Otkritie FC (2008–2013) — advisor to top executives. M&A, crisis management, support of mission-critical client services in the banking perimeter.
1992–2022 — IT infrastructure for business-critical applications. Sun Microsystems, NetApp — design, deployment, maintenance.
2008–2026 — deployment and maintenance of business-critical open-source CRM systems in the banking sector. First app321 deployment — Uralsib Bank (2021): migrating retail banking operations (cash and settlement services) from heavyweight core-banking into an open-source solution. app321 is listed in the Unified Register of Russian Software (No. 28559, 23.06.2025).
Public participation in industry and state-level discussions — CNews, IBM Forum, State Duma commission, “IT+Sovereignty” forum.
Who I work with
How I engage
I come in as an advisor to the owner or CxO, as an external partner on the owner’s side. Working through your existing contractor is also an option.
Engagement usually starts not with a “deployment project” but with a blitz audit. Where the organisation is actually losing controllability. What exactly it depends on. Where business, IT, InfoSec, and AI are disconnected. What can be strengthened quickly without breaking the living fabric of work.
The blitz audit delivers a short working framework: a dependency map, an initial diagnosis, a set of priorities, and an understanding of what can be done immediately and what cannot be touched without risk.
I can also help practically at the operational level — not just with advice.
How I don’t work
I don’t promise “turnkey transformation.” I don’t substitute myself for the internal responsibility of the top executive. I don’t sell a platform instead of understanding the situation. I don’t amplify chaos with more tools and more participants.
What the organisation gets
A result. Significant, tangible, verifiable — one we agree on before we start.
A clearer picture of where things actually stand. Reduction of false complexity. A more honest language for discussing digital risks and losses. A better understanding of where AI helps and where it creates a new layer of dependency. A foundation for a more resilient team and organisational structure — one that holds in unstable times.
And you will see what sets a clear-sighted practitioner apart from just a practitioner. “Theory without practice is dead; practice without theory is blind.”
