From Manual Work to Shipped
The point of the work isn’t the code – it’s what changes for the business once it’s running. A couple of real examples.
Custom Curtain Orders, End to End
Before
Two employees handled every custom order by hand – reading dimensions, sketching the shape, calculating the price, and emailing a quote. Slow, and mistakes led to returns.
After
Customers configure the exact product on the site. The order runs itself: PDF drawing to the plotter, PostNord shipping, invoice, and account update – no one touches it manually.
Shipping Labels for 20–50 Parcels a Day
Before
Every shipment took 5–7 minutes of manual work: validating the address, booking PostNord, printing the label, and updating records by hand.
After
One API call does all of it – address validation, PostNord booking, thermal label, and tracking. Manual work gone, and shipment errors down to a few isolated cases a month.
One engineer,
the whole stack
Building software since 2001 — 12 of those years as the sole technical owner at a Finnish logistics company: web, servers, automation, integrations, all hands-on. No major outages in those years, and the small things got fixed fast. Now I do the same, end to end, for other businesses. Based in 🇫🇮 Finland, remote worldwide.
I’m a proud father of a big family and I play ♟️ chess — it keeps the strategic thinking sharp.
Clear communication – you’ll always know what’s happening
Bugs and outages get fixed before they affect your customers
One engineer for everything – code, infrastructure, automation, AI
Software Development, Built and Shipped Hands-On
Software development for startups and growing businesses – websites, automation, AI, and the systems that keep them running. Whether you need a build or someone to own it end to end, I’ve done it.
E-commerce
Scalable online stores with everything you need: payment processing, inventory, order management, and integrations with your logistics.
Ideal for: Brands launching or scaling their online store
Business Website
A professional website for your company – services, team, case studies, contact – fast, well-structured, and easy for you to update yourself. No online store required.
Ideal for: Service businesses that need a strong site, not an online store
MVP Development
From idea to working product – fast. I’ll help you validate your hypothesis with a real, deployable product before you commit to a full build.
Ideal for: Founders and startups testing a new idea
AI Integration
Add AI features to your existing product. Whether it’s a chatbot, document processing, or smart recommendations – I’ll plug it in cleanly.
Ideal for: Products that want to add intelligence without rebuilding from scratch
Rescue Projects
Legacy modernisation for projects that are stuck, broken, behind schedule – or an AI-generated codebase that won’t quite ship. I’ll assess it honestly and get things moving, without rewriting from scratch.
Ideal for: Companies with stalled, broken, or AI-generated codebases that need to ship
API & Integrations
Connect your systems – CRMs, ERPs, payment gateways, logistics providers. I’ve integrated with 32+ markets and dozens of external platforms.
Ideal for: Companies with disconnected tools that need to talk to each other
Automation & Workflows
Replace manual, repetitive work with automated pipelines. CRM updates, reporting, notifications, data sync – hands-free.
Ideal for: Teams losing hours per week to manual processes
Telegram Bots & Mini Apps
A bot your customers or staff actually use – orders, bookings, support, internal lookups – plus Mini Apps with payments inside Telegram. From €1,600.
Ideal for: Businesses whose customers or staff already live in Telegram and are doing by hand what a bot should do
Fractional CTO
Your technical co-founder without the equity. I step into the CTO role – setting architecture, making technology decisions, and keeping your team on track.
Ideal for: Startups and scale-ups without a full-time technical leader
Technical Due Diligence
Independent review of a target company’s codebase, architecture, and team – for investors, acquirers, or founders who need an honest second opinion. Written report in 3–5 days.
Ideal for: Investors, acquirers, and founders who need an honest, fast technical assessment without paying Big4 consultancy rates
Technical SEO/GEO Audit
A developer’s audit of why your site isn’t showing up – in Google results and in AI answers. Fixed-price written report covering technical SEO, schema, indexing, AI-crawler access, and per-market keyword research.
Ideal for: Founders and CTOs whose site has technical SEO problems they can’t diagnose from a marketing audit
SEO & AI Search Optimization
Not advice – the work itself. Monthly done-for-you search optimization: technical fixes, per-market keyword research, content and blog, schema, and visibility in AI answers. €1,200/month, no minimum term.
Ideal for: E-commerce and service businesses that want search work executed, not another audit to act on
Paid Ads Management
Google Ads, Meta and Reddit run properly – conversion tracking that actually works, keywords and audiences chosen on data, and a fixed fee per channel instead of a percentage of your budget.
Ideal for: Businesses that need results this month and want the account run by someone who can also fix the landing page
Not sure where to start?
Technical Consultation €200
Stuck on an architecture decision, a tech choice, or a tricky problem? Describe it in writing – I’ll study it, prepare, and come to the call with a concrete solution proposal.
Are We a Good Fit?
You’re Probably Looking for Someone Like Me If…
- Your team burns hours on manual work that software should be doing
- You’ve outgrown spreadsheets and need real systems behind the process
- Your developers are stretched thin and things are starting to slip
- Integrations keep breaking and nobody actually owns them
- Stripe (or any payment flow) doesn’t map cleanly onto how your business works
- You want one person who understands the code and the business behind it
I’m Probably Not the Right Fit If…
- You’re hunting for the cheapest freelancer you can find
- You already have a large in-house engineering team
- You just need pixel-perfect HTML/CSS from a finished design
- You’re looking for a designer, not a technical partner

Our Meta ad account had grown into a mess of duplicated audiences and ad sets nobody remembered creating.

We’d already paid for a generic SEO audit that listed hundreds of items with no priority order.

We run both Google and Meta and previously had two separate agencies who never talked to each other – different numbers, different explanations for the same drop in leads.

We’re a small SaaS team and had no idea our sitemap only listed half our pages until Iurii’s first monthly report flagged it.

I’d built most of our MVP with Cursor and it looked finished – it compiled, the tests were green, the demo worked. It just wouldn’t survive real users.

What made me switch from our agency was the pricing model – they charged a percentage of spend, which made every conversation about ‘should we scale’ feel biased.

After the webshop launched, Iurii added a Telegram bot that pushes a notification for every order the moment it comes in, plus a daily sales summary so I don’t have to open the admin panel to know

What sold me was that Iurii didn’t promise a ranking number for month one – he explained that the technical layer is where results are guaranteed, and that rankings move on their own schedule.
