"My experience with abZ and Marian have only exceeded my expectations. From the start he completely saw my vision with building my very specific website. I knew it was a hard task but he created it with ease it seemed. I got constant updates, smart suggestions, and honest professional feedback."

Products, not pages.
Five kinds of web app we build, each around the people who use it every day.
- 01
SaaS platforms
Subscription products with accounts, teams and the features your customers pay for.
- 02
Two-sided marketplaces
Two kinds of users, listings and search, each side with its own flows.
- 03
Community platforms
Members post, vote, comment and share; you keep control of what goes live.
- 04
Dashboards and admin panels
One place to see and act on your data: filters, tables, inline edits.
- 05
Internal tools
The spreadsheets and copy-paste your team runs on, replaced by one tool built for the job.
AI features go in where they earn their place, not as a demo. AI & integrations
Every build, the same standard.
We write code the next developer can work in: structured, tested and documented. It’s the standard we hold our own product to, 5,000 commits in.
- Agreed scope and milestones before any code is written
- The application: interface, backend and database
- Sign-in, user roles and permissions
- Integrations with the services and APIs it needs
- AI features where they make sense
- Testing, deployment and documentation
Built, launched, and still running.

SelfManager.ai, a date-based AI task & project manager.
A date-based AI task and project manager with real users. Designed, built and run by Marian since 2016, with 14 AI features in production and 5,000+ commits.
Handed a half-finished app? That’s familiar work.
Many projects reach us after another developer or agency stopped. We read the code before we promise anything, and you get a written verdict. Then we stabilise it and finish the build.
- Strong
- Fragile
- Fix first
- Leave alone
Built in phases, priced in phases.
- 01Discovery and scope.
What you’re building, who it’s for, what exists today. You get a written scope and the first milestone.
- 02A first working milestone.
An MVP or a first slice of the product in your hands early, so decisions are made on real software.
- 03Phase by phase.
Each phase is scoped, priced and reviewed before the next one starts.
- 04Launch, and after.
Deployment, documentation and handover, then ongoing development if you want it.
The minimum engagement is $2,000. Full products are scoped and priced in phases.
The stack, briefly.
We build on Angular, Firebase, Node.js and Google Cloud, the stack behind SelfManager.ai. AI features use Gemini, ChatGPT or Claude, whichever fits the job and the budget. If a different stack, or no custom app at all, suits your project better, we’ll tell you.
What clients say about the build.
"I’ve had Marian work on a couple of projects and he has delivered exactly what I needed. He’s very knowledgeable and skilled. His code is clean and concise. He communicates well and precisely."
Questions before you start.
What does a web app cost?
The minimum engagement is $2,000. Most products are built in phases, each scoped and priced before it starts, so you never commit to the whole thing blind.
How long does it take?
It depends on the scope. The plan you get before work starts lists the milestones and when each one lands.
Can you take over an app someone else started?
Yes. We review the code first and tell you plainly what’s worth keeping before we quote the rest.
Which technology do you use?
Usually Angular, Firebase, Node.js and Google Cloud. If another stack fits your project better, we’ll say so and explain why.
Who does the work?
Marian personally. When a project needs more hands, he leads the team, with one person responsible.
What happens after launch?
Ongoing development each month, or a documented handover to your own team.
Can you add AI to our app?
Yes, where it earns its place. SelfManager.ai has 14 AI features in production. See AI & integrations.
