Business controlling · Data · AI
I’m Joachim Solvang — a business controller who codes. I turn financial and operational data into insight management can act on, using AI and the systems you already have.
Experience & education
Services
Advice, hands-on building, or both. I work across the whole chain — from the question management needs answered to the data, the model and the tool that answers it.
Reporting, KPIs and analysis that show what is driving the result — not just what it was. Hands-on, as an extension of your finance team.
Use AI where it makes analysis faster and sharper: finding drivers, explaining deviations, drafting commentary and answering questions from your own data — with a person accountable for the conclusions.
One set of numbers everyone trusts. Data models, integrations and dashboards across your ERP, CRM and project systems — and internal tools where standard systems fall short.
AI for analysis
AI is shifting finance from producing reports to explaining them. The value isn’t in a chatbot — it’s in faster, sharper analysis: finding the drivers, testing scenarios, drafting the story behind the numbers.
I help you find where that pays off, build it on data you can trust, and keep a person accountable for the conclusions.
Typical starting points
Deviations against budget and last year found and explained — drivers, not just differences.
First-draft management commentary on the numbers, ready for you to sharpen.
Plain-language questions answered from your own financial and operational data.
Forecasts and scenarios updated faster, with every assumption visible.
Margin by project, customer and product — and the patterns behind it.
Shifts in sales, cost and capacity flagged before they reach the result.
AI suggests. A person owns the conclusion.
Every figure can be followed back to its source.
Built with the providers and data boundaries you approve.
No large system replacement project required.
Selected work
Projects from independent work and earlier roles. The common thread: understand the business question, then build the model and the tool that answers it.
An internal portal for a Norwegian accounting and advisory firm. It brings project profitability, time entry, tasks and compliance reporting from the practice management system and Altinn into one place — rebuilt on the firm’s design system. I work as full-stack developer in a small team with a tech lead.

How we work together
No large setup project, and no long report before anything happens. We start with one concrete question and answer it properly.
Bring one concrete question — a decision you lack numbers for, a report nobody trusts, or a forecast that takes weeks. We look at it together for 30 minutes.
We pick one problem and agree a clear scope. You get a working model or tool — not a slide deck about one.
Extend it, scale it, or hand it over to your team. I can stay on for ongoing support — or step back.
About
I work where finance meets technology — so the analysis and the tool that delivers it are built by the same hands.
My work centres on business controlling and finance advisory: management reporting, budgets and forecasts, profitability and supplier analysis — at BDO, at Aider, at Coop — first as Business Controller, now building Power BI reporting — and with my own clients since 2020.
I also build. I added a degree in informatics to my business and finance degrees, led a financial data warehouse project at BDO, headed Digitalisation & Innovation at Aider, and today work as a full-stack developer on internal tools.
AI has changed how I explore ideas, analyse data and build software. Now I bring that way of working to the leaders and finance teams I work with.
