Developer for SaaS productsAvailable now
SaaS products that keep shipping long after version one.
SaaS is where most of my career has been. Six years on Dinero, a mature accounting SaaS with a large customer base. Two years and counting growing Målbar's LCA product. A year on Storebuddy. And my own booking SaaS, Tiltiden, where I handle subscriptions, payments and support myself. I know what it takes to ship features every week without breaking paying customers.

Is this a fit?
An honest fit check before we talk
I would rather tell you no on the first call than waste your budget. Here is what a good match looks like in this sector.
A good fit if
- You run a B2B SaaS product and need senior capacity to ship features and keep quality up.
- You are a founder building a SaaS MVP and want it built so it can become the real product.
- Your product needs billing, subscriptions, roles and permissions, onboarding and an admin back-office done properly.
- You want a developer who has run a SaaS himself and thinks about churn, support load and upgrades, not just code.
Probably not a fit if
- You need a full product team with design, growth and support in one contract.
- You want a no-code or low-code build. That can be a fine choice, but it is not what I do.
- Your product is built on a stack far from TypeScript, React, Vue and Node.js.
What I do
What I typically build in this sector
- Product features
- Customer-facing features shipped in short iterations from your backlog, in React or Vue with TypeScript, with a weekly written update.
- Billing and accounts
- Subscriptions and payments with Stripe or similar, plans and limits, teams, roles and permissions, invoicing and the edge cases of upgrades and downgrades.
- Admin and internal tools
- Back-office tools for support, operations and finance, so the team can help customers without asking a developer.
- Scaling the codebase
- Upgrades, performance work, tests and structure that keep feature development fast as the product and the team grow.

Process
How we'll work together
The same four steps for a two-day fix and a two-year engagement.
Intro call
A free 30-minute call where you tell me about your project, goals and constraints. I ask a lot of questions and tell you honestly whether I'm the right fit.
Proposal & estimate
You get a short written proposal: scope, approach, timeline and price. Fixed price for well-defined projects, hourly or retainer for ongoing work.
Build in the open
Short iterations, working software early, and a weekly update you can actually read. You see progress and can change course before it gets expensive.
Launch & support
I handle deployment, hand over clean documentation, and stick around for support and further development if you want me to.
FAQ
Questions I get asked
- Have you built a SaaS from scratch?
- Yes. Tiltiden is my own booking system for Danish service businesses, with online bookings, payments and reminders. I also co-built eManager's tournament platform from zero as a partner. And I have spent years inside large, mature SaaS codebases, which is a different and equally useful skill.
- Can you take over a SaaS product from a previous developer or agency?
- Yes, that is common. I start with a short audit of the code and infrastructure, write down what I find, and agree on priorities with you before changing anything important.
- What happens after launch?
- I stick around. My clients have kept me for one to six years, first for the build and then for support and further development, usually on a retainer of reserved weekly hours.
- How quickly do you learn our domain?
- Faster than most, because I ask a lot of questions before writing code. I have picked up LCA methodology, building physics, bookkeeping rules and pharma processes on previous engagements. Expect me to be useful in the first week and fluent in the domain within a month or two.
- How do you price work?
- Fixed price for well-defined projects, hourly or a monthly retainer for ongoing work. My preferred engagement is 20-40 hours a week for six months or more. Rates are in the proposal, not on the site.
- How quickly can you start?
- Current availability is on the homepage. If it says available, usually within one to two weeks after a free 30-minute intro call and a short written proposal.
