Independent consultant · Solopreneur

Hi, I'm Lars Barkman.

I bring clarity to complex digital solutions and the enterprises that run them — and help make both work in practice.

As an interim solution architect, I help build and run digital solutions: I make decisions and trade-offs clear, bring people together, and stay hands-on through production.

As an interim enterprise architect, I help build and run the enterprise around them: the operating model, ownership, and governance that let those solutions be delivered and sustained.

My approach draws on twenty years across insurance, shipping, manufacturing, and energy. Explore my experience.

Outside client work, I’m building a self-hosted platform for systematic trading. Explore my ventures.

    Modeling the Digital Enterprise as a Connected System
    A coherent metamodel for a Digital Enterprise Operating Modelβ€”connecting context, products, organization, capabilities, processes, information, digital solutions, assets, and governance without reducing the enterprise to a hierarchy of boxes.

    The Types of Enterprise Service

Consulting

Interim solution architecture and enterprise architecture: stepping into the seat, making the decisions, and staying hands-on until the work holds without me.

  • Solution Architect (Interim)
    Clear technical direction. Practical architecture. Hands-on support through delivery.
  • Enterprise Architect (Interim)
    Clear ownership. Clear decision authority. An operating model that supports delivery.

Ventures

Where I build: retail systematic trading, worked as knowledge, tooling, and services β€” the RST Model, the RST Platform, and the control planes that run it.

  • Retail Systematic Trading Model
    The knowledge that defines how retail systematic trading should be done β€” treating trading as a disciplined, repeatable process rather than a series of discretionary decisions.
  • Retail Systematic Trading Platform
    A self-hosted systematic trading platform for retail traders, just starting development β€” data, strategy, execution, and risk as one coherent system you own and control, with no vendor lock-in.
