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.
A date-based AI task and project manager with paying users. Designed, built and run by Marian since 2016, with 14 AI features, 400,000+ lines of code in production and 5,000+ git commits.
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.
Built it with AI? Lovable, Bolt, v0, Replit or Cursor get you to a working demo fast. We take it from there: sign-in and data rules locked down, keys out of the browser, tests on the paths that make money, real hosting and backups, and documentation, so you can keep building without breaking it. From $5,000, with larger rescues usually $15,000 – $40,000.
What you’re building, who it’s for, what exists today. You get a written scope and the first milestone.
An MVP or a first slice of the product in your hands early, so decisions are made on real software.
Each phase is scoped, priced and reviewed before the next one starts.
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.
We build on Angular, Firebase, Node.js and Google Cloud, the stack behind SelfManager.ai. AI features use OpenAI GPT, Anthropic Claude, Google Gemini or xAI Grok, 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.
"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."
"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."

The minimum engagement is $2,000, for a development sprint. A custom web app starts at $5,000, a SaaS MVP at $8,000 and a marketplace at $15,000. A full product is usually $50,000 – $150,000, platforms $150,000 – $500,000+, and anything larger is priced through Enterprise. Most products are built in phases, each scoped and priced before it starts, so you never commit to the whole thing blind.
A SaaS MVP takes 3–4 weeks, and a custom tool about 2 weeks. Larger products are built in phases, each with its own delivery time in the plan you get before work starts.
Yes. We start with a short audit, then lock down sign-in and data rules, move keys out of the browser, add tests on the paths that make money, and set up real hosting, backups and deploys. Rescue and modernization starts at $5,000; larger rescues are usually $15,000 – $40,000.
Yes. We review the code first and tell you plainly what’s worth keeping before we quote the rest.
Usually Angular, Firebase, Node.js and Google Cloud. If another stack fits your project better, we’ll say so and explain why.
