What does Kiril Urbonas do?

Kiril Urbonas is a freelance full-stack and AI engineer. I design, build, deploy, and run websites, web apps, e-commerce stores, SaaS platforms, and AI automations end to end for founders and small teams. I also build and operate my own live products — from a 400+ article engineering publication (DevOpsNess) to a real-time AppSec intelligence platform (ZeroDayAttack) and a native iOS app (MyHomeStock) — so clients can see the standard before they hire.

What technologies and stack does Kiril Urbonas use?

My core stack is Next.js, React, and TypeScript on the front end; Node.js, PostgreSQL, and Prisma on the back end; and OpenAI and Claude APIs, RAG, and AI agents for automation. I deploy on Vercel and AWS with Docker and CI/CD. I build on modern frameworks rather than WordPress page builders, which is why the sites I ship typically load in under 1.5 seconds and score 90+ on Lighthouse.

Which service or package is right for my project?

A quick guide: choose a Landing Page (from €500) for one focused page to capture leads or validate an idea; a Business Website (from €1,500) for a multi-page site that builds credibility and ranks in search; an E-Commerce or Web App build (from €3,000) if you sell online or need custom functionality, dashboards, and integrations; and an AI / SaaS Platform (from €5,000) for products with accounts, billing, multi-tenant infrastructure, or AI agents. If you're unsure, send the contact form and I'll recommend the smallest scope that solves your problem.

Why hire you instead of a cheaper freelancer or an agency?

Cheaper freelancers often disappear after handoff or ship a generic template; agencies layer on account managers and developers, so costs climb, communication slows, and you rarely speak to whoever is actually building your product. I do the strategy, design, development, and deployment myself - one point of contact, full accountability, no handoff gaps. You can judge the standard from the products I build and run end to end - DevOpsNess, MyHomeStock, QRify and more, all live.

What is your process for new projects?

Step 1: You fill in the contact form or we jump on a 15-minute call. Step 2: I send a custom proposal with scope, timeline, and fixed price within 48 hours. Step 3: Before writing a line of production code, you get a full design mockup to review and approve. Step 4: I build, you get weekly progress updates, and we launch. Post-launch, I'm available for a support window to fix anything that comes up.

What is your typical pricing range?

Every quote is fixed-price with no surprises. As a guide: landing pages and lead capture sites start around €500–€1,500; e-commerce rebuilds and custom web apps range from €2,000–€8,000+; AI integrations and SaaS platforms are quoted per project scope. The contact form takes 2 minutes - I'll send a custom proposal with a precise number, no obligation.

How long does a typical project take?

Landing pages: 1–2 weeks. E-commerce stores and marketing sites: 3–6 weeks. Custom web apps and SaaS platforms: 6–12 weeks. AI integrations: 3–6 weeks depending on complexity. I'll give you a specific delivery date in the proposal - not a range. If something comes up that affects the timeline, you hear about it before it's a problem.

How quickly can you start?

Usually within 1–2 weeks of proposal sign-off. I keep my project load intentionally small so I can give each client real focus - I'm not running 10 projects at once. If you have a hard deadline, mention it in the contact form and I'll tell you upfront whether it's achievable.

What if I'm not happy with the result?

That's unlikely by design. Every project starts with a full mockup - design, layout, and copy - that you review and approve before any production code is written. You request changes, I refine it, and the build only begins once you sign off. The proposal also defines clear revision rounds, so expectations are set from day one.

Do you work with clients outside your time zone?

Yes - the majority of my clients are in Western Europe and the US. I work async by default (detailed written updates, Loom videos for walkthroughs) and schedule calls to overlap with your working hours when needed. Time zones have never been a problem.

What do you need from me to get started?

An idea of what you want to achieve, your approximate timeline, and any existing brand assets or content you have. You don't need a detailed spec - that's what the discovery process is for. Fill in the form, describe the problem in plain English, and I'll take it from there.

Do you offer support after launch?

Yes. Every project includes a post-launch support window (typically 2–4 weeks) where I fix any issues at no extra cost. For ongoing support - new features, content updates, performance monitoring - monthly retainers are available. I've had clients on retainer for 2+ years.

How much does website maintenance cost?

Plans start at €200/month for monitoring, updates, security patches, and priority bug fixes. AI agent maintenance starts at €350/month, and retainers with 10 hours of development time for new features start at €800/month. All flat-priced - no hourly surprises.

Can you maintain a website you didn't build?

Usually, yes - I work with Next.js, React, Node.js, and most modern stacks. I start with a free audit of your site's code, performance, and security, and tell you honestly whether a maintenance plan makes sense or whether a rebuild would serve you better.

What happens if my site goes down?

Monitoring alerts me automatically, usually before you notice. Critical issues get worked on the same day under every plan, with faster guaranteed response times on higher tiers. You also get automated backups, so recovery is a restore, not a rebuild.

Is there a long-term contract?

No - plans are month-to-month and you can cancel anytime. Clients stay because the site keeps performing, not because of a contract; several have been on retainer for 2+ years.

What if I need new features, not just upkeep?

That's what retainer hours are for: from €800/month you get 10 hours for feature development, A/B tests, or anything else, with priority scheduling and unused hours rolling over one month. For bigger pieces of work, I'll quote a fixed price separately.

Website maintenance & retainers that keep your site earning

Websites don't stay fast, secure, and ranking on their own. My maintenance plans start at €200/month and cover updates, security patches, monitoring, and priority fixes - handled directly by a senior engineer, not a ticket queue. Your site keeps performing; you keep running your business.
