Interim tech lead · Stockholm

An interim tech lead who still writes code.

When the team lacks direction, when releases run late or when a tech lead has left. I step in, set architecture and ways of working, and stay in the code. At Vattenfall I spent five years making sure four teams followed the same standards for design, performance and security.

Taking new assignments

What you get

  • Direction on one page

    Architecture, priorities and ways of working that everyone in the room understands. Written down, so it outlives me.

  • Decisions that get made

    Framework, platform, build or buy. The experience to choose fast and right, and to say no to what is not needed.

  • A team that grows

    Code review, pairing and mentoring. The goal is that you do not need me when the assignment ends.

Selected work

Relevant experience.

  1. Solution designer2019–2024

    Web services that meant customers no longer had to call. One shared Angular framework across departments, CI/CD in Azure, and deployments without downtime.

    Angular · Azure DevOps · .NET · Optimizely

  2. Senior frontend2016–2017

    A video editor that runs entirely in the browser: cut, handle frames, caption. Built side by side with the backend team.

    AngularJS · REST · Jenkins

  3. Developer experience consultant2026

    Split a 259-project Nx monorepo so type-checking and the editor were fast again. Built tooling that keeps the structure intact.

    TypeScript · Nx · Drizzle ORM · Next.js

How it works

Three steps. No surprises.

  1. We talk

    Thirty minutes. You tell me where it hurts, I listen and ask the questions that usually decide things.

  2. I draw the plan

    What gets built, in what order, and what it costs. On one page, so everyone in the room understands it.

  3. We build

    Short cycles. Real code in production early. You see progress every week, not at the end.

Common questions

Common questions about interim tech lead and solution architect

What does an interim tech lead do?

Takes technical responsibility for a team for a limited time: architecture, code quality, priorities and decisions. The difference from a manager is that I write code and make decisions from inside the team.

How long is a typical assignment?

Three to twelve months. Often until you have recruited, or until the team stands firmly on its own.

Can you help recruit my replacement?

Yes. Requirements profile, technical interviews and onboarding. I hand over when it is done, not when the clock rings.

Can you review our platform before a decision?

Yes, technical due diligence before an investment, acquisition or a major rebuild. You get a plain-language report with what actually matters.
