A solo developer for founders. I take it from decision to production, without step-by-step specs.
TypeScript, React, Next.js, Astro, Node.js, Cloudflare Workers, Anthropic API, MCP
Fully solo: front end, back end, payments, deploy.
Answerly: real-time chat, auth, Stripe Checkout and Connect, payouts. Built solo.
LLM features, agents, MCP servers, answers only from your data.
Money Track: ~97% categorisation accuracy at ~80% lower cost.
An agent that does one job and checks its own work.
Keyline: the agent animates a live scene, renders its own frames and checks them against your references.
Speed, AI cost, reliability, SEO.
AI Telegram Assistant: running cost down from $75–150 to $3–6 a month.
Code that broke, can't handle the load or falls over on real data.
Money Track: the model invented numbers. Every calculation moved into SQL, and a check blocks any figure the database didn't produce.
Every edit, yours or Claude's, is one undo step.
Motion editor where your own Claude animates a live scene and you point at any frame to fix it.
The model never computes a number.
An AI finance app where every number comes from SQL: ~97% categorisation accuracy at ~80% lower cost.
Sole developer: chat, auth and Stripe payouts.
A creator startup built end to end by one developer: real-time chat, auth, Stripe Checkout and Connect, payouts.
The product, the users and the goal. I don't wait for a step-by-step spec.
ppc.io: solo for ~22 months, tools library grew from 19 to ~78.
I explain why and bring my own option. If you still want it your way, I build it and write down the risks.
Money Track: better prompts didn't stop the model inventing numbers, so I moved every calculation into SQL.
Fewer features, faster to users.
Job Radar: the model only where it's needed, cost down from ~$15 to $1–2 a month.
Money, conversion, cost, stability.
AI Telegram Assistant: running cost down from $75–150 to $3–6 a month.
Kyiv, Ukraine
Hi, I'm Vitaliy, or just Italik. I'm a full-stack developer from Kyiv who's been shipping for the web for 3+ years, taking products from a Figma file all the way to production.
Now I focus on AI: I build agents from scratch, wire LLMs into real products and keep them honest about the data. In Keyline your own Claude edits a live animation through an MCP server; in Money Track the model never computes a number.
I enjoy owning a feature from idea to something that actually ships. I work remotely from Kyiv, alongside designers and, where there are any, the client's own developers, and I'm happy to own the whole stack or slot into an existing team.
Live demo
It knows my projects and how I work. Ask anything about building your product with me.
Site content and my notes are loaded into one cached prompt. The model answers only from them and cites the files it used.
Italik.aiExample answer
It keeps the model away from arithmetic. Every number comes from one canonical SQL layer over D1, and each user's data is isolated in its own Durable Object. The LLM advisor only receives those query results as grounded context and explains them; it never computes totals or writes to the data itself.
Send me the goal, not a spec. Telegram or email, I reply the same day.
