You will get Stripe Payments Integration into custom or under any CMS website
Project details
I've integrated Stripe across 4 production projects covering 35 countries, 13 currencies, and 6 payment methods. All live right now:
• pikkuna.fi — 35 countries, 13 currencies. Fully automated: Stripe webhook → CRM → accounting → PDF invoice. Zero manual order processing.
• pi-pi.ee — B2B across 32 EU markets. Cards, PayPal, Revolut Pay, SEPA, Bank Transfer, Multibanco. VAT reverse charge.
• vatnode.dev — SaaS subscriptions with Customer Portal, plan upgrades, usage tracking.
• htpbe.tech — Tiered billing ($15–$499/month), live/test API key environments, quota enforcement.
Most developers handle checkout.session.completed and call it done. I handle the full lifecycle: payment failures, grace periods, dunning, idempotent webhooks, and edge cases that silently break billing at scale.
From one-time checkout to multi-currency subscriptions with EU VAT compliance — message me with your billing model and I'll confirm scope.

+$1,500About Iurii
Senior Full-Stack Dev | React, Next.js, Node.js | SaaS & E-commerce
Lappeenranta, Finland - 5:48 pm local time
That's what I do.
I'm Iurii — a senior full-stack developer with 25+ years of experience, based in Finland. I started coding in 2001 at a web agency. Spent 12 years as CTO at a logistics company, building all digital infrastructure from scratch. Most recently was Head of Development on an international e-commerce platform covering 25+ markets — multi-currency, automated order pipelines, AI chatbots, complex payment integrations.
Now I'm freelancing. I take on projects where I can make a real difference.
What I build:
- SaaS products and MVPs (from concept to live in days, not months)
- E-commerce platforms (multi-country, multi-currency, Stripe, VAT automation)
- REST APIs and backend services (Node.js, Python, FastAPI, Hono)
- AI integrations (OpenAI, RAG chatbots, embeddings, automation pipelines)
- Third-party integrations (Stripe, Zoho CRM, Airtable, PostNord, GA4, Meta CAPI)
- Rescue projects (when a project stalled, a contractor disappeared, or the code is a mess)
Tech I work with daily:
React, Next.js, TypeScript, Node.js, Python, PostgreSQL, Redis, Docker, Stripe, OpenAI
Recent projects (all live, all built by me):
Pikkuna — International E-commerce
30 languages, 35 countries, 13 currencies. Fully automated: Stripe → Zoho CRM → Airtable → PostNord → PDF invoice. Manual order processing: 30 min → under 2 min. RAG-based AI chatbot in 25+languages.
HTPBE — PDF Authenticity SaaS
5-layer forensic analysis in under 9 seconds. API-as-a-Service $15–$499/month. Solved Vercel's 4.5 MB limit with two-stage upload handling files up to 10 MB.
vatnode — EU VAT Validation API
REST API replacing unstable EU VIES SOAP service. Redis caching: 2–5s → under 100ms. ~10,200 lines of fully typed TypeScript.
pi-pi.ee — B2B E-commerce for 32 European Markets
28 languages, automatic VAT + VIES validation, 6 payment methods, server-side PDF invoices.
How I work:
I over-communicate. You always know what I'm working on and when it'll be ready. I deliver a working first milestone fast — something you can show, test, or demo. I read your spec before asking questions. I come prepared.
I don't just write code. If I see something blocking the project, I flag it early. You hired me to solve problems, not to invoice you.
Good fit for:
- Startups that need an MVP without burning months of runway
- E-commerce businesses expanding to new markets
- Companies that need complex integrations done right
- Teams that had a developer disappear and need someone to pick up the pieces
Send me a message with what you're building. I'll tell you honestly if I can help — and how.
