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 a business website cost?

Landing pages start at €500; multi-page business websites start at €1,500. Every quote is fixed-price - you see the exact number and a free design mockup before committing. If the scope changes mid-project, we adjust the quote before any extra work begins.

Do I own the website when it's done?

Yes - 100%. You own the code, the design, the domain, and the content. No lock-in, no proprietary platform, no ongoing licence fees. If you ever want another developer to take over, they can.

Why not just use WordPress or Wix?

Page builders are fine until you need speed, search rankings, or custom functionality. I build on Next.js and React, which is why my sites load in under 1.5 seconds and score 90+ on Lighthouse - performance most template sites can't reach. That speed translates directly into better rankings and more conversions.

What happens after launch?

Every website includes 1-2 months of post-launch support - bug fixes, minor adjustments, and performance monitoring at no extra cost. After that, optional maintenance plans start at €200/month if you want ongoing updates and monitoring.
