Custom Software Development for Startups and Growing Businesses
I provide custom software development and technical consulting — from the first MVP to the systems that run your operations every day. One senior engineer who has been the CTO, not a chain of handoffs.
Most growing companies reach a point where IT stops being invisible. Orders are processed manually. Data lives in spreadsheets. Systems don't talk to each other. One manager spends half their day copying information between platforms.
I bring order to IT infrastructure that has grown without a plan — automate the manual work, connect the systems that should already be talking to each other, and build workflows that run without someone babysitting them.
25+ years in development. 12 years as CTO at a Finnish logistics company — one person responsible for everything. Now I do the same for other businesses.

Technologies in production
Real orders and payments running through production systems I built and still maintain.
Business Systems
The software that runs your operations — internal tools, dashboards, and the wiring between your CRM, ERP, and payments.
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.
What's included
- Full-stack web application (Next.js + Node.js / Python backend)
- Authentication, user management, basic roles
- Payment processing (Stripe) if needed
- Deployed to production (Vercel, Railway, or your infra)
- Clean, documented codebase — you own it fully
Ideal for: Founders and startups testing a new idea
Connect your systems — CRMs, ERPs, payment gateways, logistics providers. I've integrated with 32+ markets and dozens of external platforms.
What's included
- REST and GraphQL API design and implementation
- Stripe, Zoho CRM, Airtable, ERP integrations
- Webhooks, event queues, and real-time data sync
- OAuth 2.0 and API key authentication flows
- Rate limiting, retry logic, and error alerting
- API documentation
Ideal for: Companies with disconnected tools that need to talk to each other
Automation & AI
Take the manual, repetitive work off people — automated pipelines, integrations, and AI that does a real job in production.
Replace manual, repetitive work with automated pipelines. CRM updates, reporting, notifications, data sync — hands-free.
What's included
- Business process automation (order flow, reporting, notifications)
- Telegram and WhatsApp bots as the front end to an internal process — status lookups, approvals, on-demand reports
- Data pipelines and ETL between systems
- Scheduled jobs and background workers
- Multi-channel notifications (email, Slack, Telegram, SMS)
- Monitoring and alerting for automated processes
- Dashboard for visibility into automated workflows
Ideal for: Teams losing hours per week to manual processes
Add AI features to your existing product. Whether it's a chatbot, document processing, or smart recommendations — I'll plug it in cleanly.
What's included
- OpenAI (GPT-4o) and Claude integration
- RAG (retrieval-augmented generation) with vector search
- AI chatbots with conversation memory and context
- Chatbots on the channels your customers already use — Telegram, WhatsApp, Slack, or a widget on your own site
- Document analysis, extraction, and classification
- Embedding pipelines and semantic search
- Prompt engineering and output validation
Ideal for: Products that want to add intelligence without rebuilding from scratch
Telegram Bots & Mini Apps
from €1,600
A bot your customers or staff actually use — orders, bookings, support, internal lookups — plus Mini Apps with payments inside Telegram. From €1,600.
What's included
- Conversation design — the flow, the menus, and what happens when the user says something unexpected
- State and storage: a real database behind the bot, not in-memory state that dies on restart
- Integration with the systems you already run — CRM, ERP, spreadsheets, your own API, or a webshop
- Payments inside Telegram (card providers or Stars) with order records you can reconcile
- Mini App (Next.js) when the task needs a real interface instead of a chat flow
- Admin side: who can use what, an operator view, and alerts when something fails
- Deployment, monitoring, and logs — plus the source code and the hosting setup, in your accounts
From €1,600 for a bot with a defined flow, storage, and one integration. Mini Apps and payment flows are quoted on top, after the scope is written down.
Ideal for: Businesses whose customers or staff already live in Telegram and are doing by hand what a bot should do
E-commerce
Storefronts and B2B platforms built to sell across Europe — Stripe and Klarna, multi-currency, EU VAT, and customer portals.
Scalable online stores with everything you need: payment processing, inventory, order management, and integrations with your logistics.
What's included
- Custom storefront (Next.js) or headless integration
- Stripe, PayPal, Klarna, and local payment methods
- Multi-currency pricing and EU VAT handling
- Inventory management and order automation
- CRM and ERP integrations
- Shipping and fulfilment provider integrations
Ideal for: Brands launching or scaling their online store
Technical Leadership
Senior technical judgment when a full-time hire is too early — architecture, audits, performance, and rescue.
Your technical co-founder without the equity. I step into the CTO role — setting architecture, making technology decisions, and keeping your team on track.
What's included
- Technology strategy and quarterly roadmap
- Architecture decisions and code reviews
- Engineering team structure and hiring support
- Vendor and tool evaluation and selection
- Technical due diligence for investors or acquirers
- Weekly involvement — calls, reviews, decisions
Ideal for: Startups and scale-ups without a full-time technical leader
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.
What's included
- Full codebase audit: architecture, security, performance
- AI-generated codebases: dead-code removal, dependency cleanup, real test coverage
- Honest written assessment of what's there and what it'll take to fix
- Prioritised fix plan: critical bugs first, then tech debt
- Bug fixing, refactoring, performance improvements
- Documentation and knowledge transfer
Ideal for: Companies with stalled, broken, or AI-generated codebases that need to ship
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.
What's included
- Codebase quality review: maintainability, test coverage, dependency health
- Architecture assessment: scalability, single points of failure, technical debt
- Security posture: authentication, data handling, common vulnerabilities
- Infrastructure and deployment review: CI/CD, observability, resilience
- Team and process assessment: documentation, knowledge concentration, on-call readiness
- Written report with executive summary, risks ranked by severity, and remediation cost estimates
Ideal for: Investors, acquirers, and founders who need an honest, fast technical assessment without paying Big4 consultancy rates
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.
What's included
- You submit the problem in writing (I send a template)
- I research and prepare — no improvising on the call
- 50-minute video call the next day with my concrete recommendations
- Written summary with action points after the call
100% prepayment — I book time only after payment is received.
Ideal for: Founders and CTOs who need expert input without hiring full-time
Search & Visibility
Being found — in Google results, in AI answers, and in paid placements. A one-off developer's audit, or the monthly work of actually doing it.
SEO/GEO Optimization
€1,600/mo
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. €1,600/month, no minimum term.
What's included
- Technical SEO, done and kept done — crawlability, robots.txt, sitemaps, canonicals, hreflang, indexing issues, redirects, broken links, Core Web Vitals
- Per-market and per-language keyword research, mapped to search intent and to actual pages on your site
- On-page optimization — titles, meta descriptions, headings, internal linking, page structure, rewriting pages that target nothing
- Content and blog — I plan it, write it, and publish it, in the languages your markets use; not a content calendar for you to fill in yourself
- Schema.org / structured data implemented in the code: Organization, Product, Service, Article, BreadcrumbList, FAQPage, LocalBusiness where relevant
- GEO layer — AI-crawler access (GPTBot, ClaudeBot, PerplexityBot, Google-Extended), llms.txt, answer-ready pages that state facts an assistant can quote
- IndexNow and Search Console operations — instant indexing on change, plus monitoring and fixing what Google reports
- Analytics you can actually read — Search Console and GA4 or a cookieless alternative, wired up so the numbers mean something
- Monthly written report: what was done, what moved, what's planned next month
€1,600/month for the first 6 months — the phase where errors get fixed, the blog gets set up, and the research is done. €800/month from month 7, when the work becomes maintenance.
Ideal for: E-commerce and service businesses that want search work executed, not another audit to act on
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.
What's included
- Per-market and per-language keyword research — actual search demand in the countries and languages your site targets, not a generic English list
- Broken-link scan with Linkinator — every internal and external link checked; broken links cost crawl budget and tank user trust
- Schema.org audit and recommendations — what structured data is missing, what's malformed, what should be added (Organization, Service, Article, BreadcrumbList, AggregateRating, FAQPage where relevant)
- AI-crawler access review — whether GPTBot, ClaudeBot, PerplexityBot and Google-Extended can actually reach your content, and whether that matches what you want; blocked by accident is the most common finding
- llms.txt review — the emerging standard for telling LLMs what your site is about, checked against what your site actually offers and charges
- Answer-ready content check — whether your key pages state facts (prices, coverage, terms, who you serve) in a form an AI assistant can quote instead of paraphrasing a competitor
- IndexNow setup check — instant indexing protocol used by Bing and Yandex; pings search engines the moment content changes instead of waiting for the next crawl
- OG image recommendations — what's missing, what's wrong, how to make link previews work properly across LinkedIn, X, Slack, iMessage
- Core technical SEO: crawlability, robots.txt, sitemap.xml, canonical tags, hreflang for multi-market sites, Core Web Vitals, indexability issues from Search Console
- Written report (PDF or Notion) — prioritised findings, severity, and exactly what to change. No filler.
Fixed price €800, paid upfront. Delivered as a written report within 5 working days of access being granted.
Ideal for: Founders and CTOs whose site has technical SEO problems they can't diagnose from a marketing audit
Paid Ads Management
€400/mo per channel
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.
What's included
- Conversion tracking done properly first — GA4, Google Ads and Meta conversions, server-side tracking and Consent Mode where the browser loses events, verified against your real orders or leads
- Account structure built or rebuilt — campaigns, ad groups, match types, audiences, exclusions; most inherited accounts are structurally broken rather than badly bid
- Keyword and audience research per market and language, with the negative-keyword list that stops you paying for the wrong intent
- Ad copy written and tested — variants that get measured against each other, not one set written once and left alone
- Weekly optimization: search-term review, negatives, bids and budgets, placement and audience cleanup, pausing what doesn't convert
- Landing-page fixes when the page is the bottleneck — I change the page myself instead of filing a ticket with your developer
- Monthly written report: what was spent, what it produced, what I changed and what happens next month
- Channels: Google Ads, Meta (Facebook/Instagram), Reddit Ads — pick one or several
€800 for the first month per channel (setup), €400/month per channel after. Channels: Google Ads, Meta, Reddit.
Ideal for: Businesses that need results this month and want the account run by someone who can also fix the landing page
How It Works

Fill in the contact form or send an email. A few sentences is enough — what are you building, what's the challenge, what's your timeline.
02
We have a short call
Usually 30–45 minutes. I'll ask questions, understand the scope, and tell you honestly if and how I can help.
03
I send a proposal
A clear scope of work, timeline estimate, and price. No hidden costs, no vague deliverables.
04
We get to work
First milestone is always something you can see or test. I over-communicate and you always know what I'm working on.
Not Sure What You Need?
That's completely fine. Most of my best projects started with "I have this problem, I don't know how to solve it."Book a consultation call and we'll figure it out together. If I'm not the right person for the job, I'll tell you that too.
AvailableReady to start?
Tell me what you're building or stuck with. I'll reply within 24 hours.
