Custom software that gives you back the time lost to repetitive work.

We build solid software for companies that have outgrown spreadsheets, off-the-shelf tools and apps that don’t talk to each other. We start with a conversation — not an invoice.

// 01 — Philosophy

I believe in conversations more than in price packages.

Principle 01non-negotiable

Solid software, not duct-taped prototypes

Tested code, clean architecture, technical documentation. What we deliver must be something another developer can pick up — no surprises, no hidden architecture.

// mature stackopen by default
Principle 02non-negotiable

Conversation before numbers

Investment is discussed only once we understand the problem. Nobody gets back-of-the-envelope estimates by email. Two apps that look alike can differ 10x in effort.

// no vague estimatescontext first
Principle 03non-negotiable

You talk directly to the person who builds it

No middleman project managers, no “our team will look into it”. Owner, founder and developer in one person, with specialist subcontractors brought in only when the project calls for it.

// direct channelsnothing lost in translation
// 02 — What we build

Software that replaces work, not just interfaces that look good.

We don’t sell generic packages. Every project is built for your specific context. Below are the patterns we work to — the exact shape gets calibrated in the Strategy Session.

Type · Pilotfirst step

A focused pilot app

One critical process, delivered cleanly. For companies that want to test the collaboration before investing in something bigger. Ideal for an internal workflow, a client portal or a dashboard.

// small scope, big impactweb or mobile
Type · Completesweet spot

A complete end-to-end app

Our sweet spot. A solid backend, a modern frontend, a mobile companion when the case calls for it, integrations with your existing systems, and AI where it adds real value.

// core offeringweb + mobile + AI
Type · Enterpriselarge scale

An enterprise system or custom ERP

For companies that have outgrown generic SaaS and need a system shaped around their real processes. Multi-tier, with data migration and integrated modules.

// replaces SaaSserious architecture
// 03 — Where we start

A one-hour conversation. You leave with a written report.

/ Strategy Session · free, no strings attached

We talk about your business. We find what’s worth automating.

One hour, on video, in English. Open questions about your operations — not a sales call. In 60 minutes, clients often put into words what they’d been struggling to name for months. You leave with a document, not a pitch.

/// step 01 — before the call

Researching your context

We look at your company — website, industry, audience — and prepare 2–3 hypotheses so we don’t start from zero.

/// step 02 — the conversation

One hour, video, structured

We talk through your processes, frustrations and ambitions, and find together where technology can make the biggest difference.

/// step 03 — the report

Written recommendations

A diagnosis, your top 3 opportunities in priority order, and something concrete you can try on your own — without us.

  • Written report
  • No sales pitch
  • DIY recommendations
  • Informed decision

// 04 — Systems

Three systems. Three industries. A demo of each.

We don’t sell slides. Below are real systems, built for real companies and used every day. Details and demos are shown confidentially, in the Strategy Session.

Carpatia

A digital ecosystem for a hospitality destination with multi-cabin bookings, a restaurant and daily operations. One source of truth for everything that used to live in diaries, sheets, messages and emails.

A custom ERP for InstalGroup — an installation company with 50+ employees and many active projects. It replaces each department’s spreadsheets with a single app: a report takes one second, not a dig through 3–7 files. Plus integrations with the SaaS tools they already use.

// 05 — How we work

Rules we don’t negotiate.

Engineering quality
Tested code. Clean architecture. Documentation that doesn’t go stale. The apps we build must be something another developer can take over without pain.
Conversation > numbers
Investment is discussed only in context, once we understand the real problem. Nobody gets back-of-the-envelope estimates by email.
Iterative delivery
Short sprints, a demo after each one. You see real progress, not a “surprise at the end”. No endless “just two more weeks”.
Open by default
Open-source stack wherever possible. You’re not locked in — by licences or by us. The code is yours. The hosting is yours. Full independence at handover.
24h response
To every email, message and bug report. Within business hours, no exceptions. This isn’t a marketing promise — it’s a clause in the contract.
Clear scope, not open-ended
We don’t sell endless “time & materials” hours. We sell delivered applications with a start, an end and a definition of “done” agreed at kickoff.
Remote, in English
Calls, written reports, documentation and code — all in English. The booking calendar shows every slot in your own time zone.
// 06 — Who builds it

You talk to the person who writes the code.

// 07 — Tech stack

Technologies that won’t go out of fashion in the next hype cycle.

A mature stack, large communities, vendor-neutral. We choose tools you can keep for years — not the newest thing on Hacker News.

// Backend

  • Java 21 LTS, fast
  • Spring Boot 3 framework
  • PostgreSQL 17 database

// Web

  • Next.js 15 App Router + Server Actions
  • React 19 UI library
  • Tailwind 4 design system

// Mobile

  • React Native iOS & Android
  • Expo + EAS build & deploy
  • OTA updates no store re-release

// AI & Hosting

  • Claude preferred
  • OpenAI fallback
  • VPS own infrastructure
// 08 — Let’s talk

A conversation costs nothing. Your decision, though, matters a lot.

If you have a problem a system could solve — or you don’t yet know exactly what you need — that’s fine. The Strategy Session is built for exactly this moment.
