Cases

What I have done, told briefly.

Client names are shared in conversation, not on a website.

AI · Own product

An AI agent working for real businesses

Situation
Freelancers and small businesses with no time to learn AI and afraid of putting their data into a generic chat.
What I did
I designed and built Zina: one agent per customer on its own server, Telegram as the only channel, voice transcribed locally, memory, confirmations and daily backups.
Result
Customers in production across several sectors and a full restore tested in minutes.

Engineering · Platform

From own servers to AWS without stopping the product

Situation
An advertising platform with a PHP monolith and servers that no longer kept up with growth.
What I did
I dockerised the environments, broke the monolith into services and, as Engineering Manager, led the migration to AWS EKS with infrastructure as code.
Result
Daily deployments, an event-driven architecture and teams with a clear owner for every part.

Leadership · Process

From fixed cycles to milestone flow

Situation
Several product teams starting on the same day, cycles padded with filler topics and stakeholders never knowing when anything would ship.
What I did
With product I designed the move to Continuous Alignment: shaped milestones, a backlog per cluster, managers pulling when capacity exists and asynchronous quality gates.
Result
A written, approved operating model in motion, with no filler topics.

AI · Hotels

AI in hotel marketing, with judgment

Situation
Independent hotels with healthy demand, too much dependence on intermediaries and a new question: how does AI describe them to their guests?
What I did
Alongside Cometa Web I prepared the direct-sales workshop for the Tourism Innovation Summit 2026 and joined the panel on AI in hotel marketing.
Result
A clear thesis for the sector: AI creates value when it improves one concrete decision. And a partnership that continues.

The proof

Zina, my own agent, already works for small businesses.

An AI virtual employee on a dedicated server in Europe, spoken to on Telegram. It runs calendar, tasks, documents and customers from day one. Not a demo: mine messages me every morning before coffee.

  • One server per customer, in Europe
  • Confirms before acting and cites its sources
  • Daily backups with tested restore
