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 an AI chatbot or automation cost?

Projects start at €1,500 for a focused automation or customer-facing chatbot, fixed price. More complex builds - multi-step agents, deep CRM integrations, document processing pipelines - are quoted per scope, typically €3,000-€8,000. You get an exact number and a working prototype before committing.

Will the AI give wrong answers to my customers?

Every agent I build has confidence-threshold escalation: when it isn't sure, it hands the conversation to a human instead of guessing. It's also trained only on your approved content, and we review real conversation logs together during the first weeks to tighten accuracy.

How long does it take to launch?

A focused chatbot or automation ships in 3-6 weeks depending on complexity. You see a working prototype on your own data within the first two weeks, then weekly demos until launch.

What tools does it integrate with?

Website chat, Slack, email, WhatsApp, and CRMs and helpdesks like HubSpot and Zendesk. I build on OpenAI and Claude APIs with RAG over your own documents and databases, so the agent plugs into the tools your team already uses.

What happens when the AI needs updating?

Every project includes 3 months of post-launch support. After that, an AI maintenance plan from €350/month covers model tuning, knowledge base updates, escalation rule adjustments, and a monthly performance report - so accuracy improves over time instead of drifting.

AI automation & chatbots that take real work off your team

I build AI automations and chatbots for businesses from €1,500, fixed price. Agents trained on your own data - product catalogs, policies, past conversations - that answer customers, qualify leads, and process documents around the clock. Clients typically automate 60-80% of the manual work we target.

Automate the work your team dreads

If a task happens more than 10 times a week, it can probably be automated. Clients automate 60-80% of targeted manual work - support tickets, reports, data entry, lead qualification.

Trained on your business, not the internet

Your agent runs RAG over your actual documents, catalogs, and policies - so it answers like someone who works for you, not a generic bot.

Humans stay in the loop

Confidence-threshold escalation means the AI hands anything uncertain to a person. You get speed without the risk of a chatbot going rogue.

Fixed price, measurable ROI

You get a fixed quote and a working prototype before full rollout. Most automations pay for themselves within months in saved hours alone.

MyHomeStock - AI-Powered Household Inventory

A self-initiated product I built and run end-to-end - live at myhomestock.cc with a native iOS companion. Most pantry-tracker apps die from data-entry friction; MyHomeStock kills that friction by letting you scan a grocery receipt with your phone - Gemini extracts the line items, merges them into your inventory, records prices for spending insights, and feeds a shared shopping list that builds itself.

ZeroDayAttack - AppSec Intelligence Aggregator

A self-initiated security product I built and run - live at zerodayattack.net. The single real-time intelligence source an AppSec engineer checks: CVEs, CISA KEV, EPSS, exploit signals, threat actors, IOCs, vendor/PSIRT advisories and security research - unified, normalized, deduplicated, searchable and pushed live from ~85 feeds. Plus an authenticated workspace that turns intel into action: asset profiles drive a personalized patch queue, with watchlists/alerts, triage, remediation SLAs and Jira/GitHub/SIEM hand-off.

StocksView - Personal Stock Analysis Terminal

A self-initiated stock-analysis terminal I built and run - live at stocksview.app. A single-screen "personal terminal" that pulls watchlists, real-time quotes, 1-month trends, sector heatmaps, bias/convergence signals and per-ticker news into one fast dashboard - aggregating Finnhub, FRED, SEC EDGAR, Yahoo Finance and Stooq.
