Subscription Platform Developer
Looking for subscription platform developer? I'm Olle Evertsson, an independent fullstack engineer based in Stockholm helping teams ship production-grade systems across recurring billing dev, stripe saas integration, subscription engineer.
Stockholm is full of developers — but few have deep experience shipping production-grade systems end-to-end. My focus is work that actually ships, gets paid for by real customers, and is maintained over time.
In practice I work with: recurring billing dev, Stripe SaaS integration, subscription engineer.
Why work with me
- Senior fullstack experience across Next.js, React Native, AI, and Postgres.
- Fixed price per phase — no hourly billing for uncertain work.
- You own 100% of the code, infrastructure, and credentials.
- Delivered from Stockholm, working with clients across the Nordics and EU.
- GDPR-compliant architecture from sprint one — not bolted on afterwards.

Frequently asked questions
How long does it take to build a SaaS MVP?+
A focused MVP typically ships in 8–12 weeks. We prioritize the three core features that drive retention and expand iteratively based on real user data.
What stack do you recommend for a B2B SaaS?+
Next.js + TypeScript, Postgres (Neon or Supabase), tRPC or REST, and Vercel for deployment. Low ops cost, fast iteration, and EU data residency for GDPR.
What does SaaS development cost?+
An MVP usually lands between €25k–€60k depending on scope. I work fixed price per phase so you know what you pay for before we start.
Do I own the code?+
Yes. You own 100% of the source code, repositories, infrastructure, and credentials. No vendor lock-in.
How is GDPR handled?+
All data lives in EU regions. Consent management, data minimization, export endpoints, and SSO/MFA are implemented from day one.
