Independent consultant · Solopreneur

Hi, I'm Lars Barkman.

I bring clarity to complex digital solutions and the organizations behind them — and help both work in practice.

As a solution architect, enterprise architect, and engineering manager, I connect solution design, team capabilities, and how the organization operates. Sometimes that means changing the design; sometimes it means helping the team learn, adapt, or grow.

Twenty years across insurance and pensions, shipping, manufacturing, energy, and enterprise software.

Outside client work, I’m building i26g, a self-hosted platform for independent systematic trading.

Notes on organizations, technology, and the full lifecycle of digital solutions — from tactical detail to strategic perspective.

    Handing the Trading Platform a Boundary
    Why the i26g Control Plane does not take its foundation on trust: you give it a bounded environment and boot one VM, and from there it verifies its preconditions and manages everything inside — VMs, networks, and the platform itself — while your infrastructure stays yours.

    From RST to i26g
    Why Retail Systematic Trading became i26g, Independent Systematic Trading: the word that was wrong, the alternatives I weighed, the numeronym, the domains, and what changed with the name.
  • Nov 8, 2026solution-design
    My Laptop as Infrastructure Control Plane and Client
    Why my laptop owns the infrastructure but not the workloads: it bootstraps the foundation, hands day-to-day operations to a Git-driven Application Control Plane, and connects to remote VMs that keep working when the lid is closed.

Consulting

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

  • Solution Architect
    Clear technical direction. Practical architecture. Hands-on support through delivery.
  • Enterprise Architect
    Clear ownership. Clear decision authority. An operating model that supports delivery.
  • Engineering Manager
    Steady leadership for your engineers. A team structure that fits the work. Delivery that improves.

Where I build: i26g, independent systematic trading, worked as knowledge, tooling, and services — the i26g Library, the i26g Platform, and the control plane that runs it.

  • i26g Library
    The knowledge around independent systematic trading — data, research, testing, sizing, risk, and operations — with a model of how the work should be done at its core. Methods and engineering, never trade recommendations.
  • i26g Platform
    A self-hosted platform for independent systematic trading, just starting development — data, strategy, execution, and risk as one coherent system you own and control, with no vendor lock-in.
  • i26g Control Plane
    Everything inside the trading environment it is given — VMs, networks, and storage — and the life cycle of the i26g Platform on them, reconciled continuously from Git with trading-aware checks.
