ARCHITECTURES

The right shape for your system.

Monolith

One deployable, fastest way to market. Usually the right call for an early product.

Microservices

Independent services, so teams can build, deploy and scale without stepping on each other.

Serverless

You pay per execution, it scales to zero, and there are no servers to maintain.

Event-Driven

Systems that react to what happens: asynchronous, resilient and close to real time.

Layered

Clear separation of concerns. Proven, readable and easy to maintain.

SOA

Shared services that the whole enterprise can reuse.

THE GALAXY

Every star is a technology we ship with.

OUR PRODUCTS

We build our own, too.

These are products we are building ourselves. We are happy to show them to you, and you can join in as a client, a partner or an investor.

AI doesn't do the work for us. We use it to apply our own experience and approach faster, so every delivery gets quicker without losing quality.

Employee AssistantIN DEVELOPMENTLOOKING FOR PARTNERS

An AI-assisted employee management platform that puts onboarding, training, equipment, shifts and leave in one HR portal. On the floor, employees tap an NFC card to wake Iris, a voice kiosk they use to clock in, request time off, book meetings, swap shifts and ask questions answered from a role-scoped knowledge base (RAG).

KaladontIN DEVELOPMENTMULTIPLAYER GAME

The classic Balkan word-chain party game, rebuilt as a real-time multiplayer platform with quick matches, custom rooms, Balkan-flavoured rank progression and a premium tier. Under the hood it runs on six Go microservices talking over gRPC, a Redis-cached dictionary of 1.58M Serbian words and a GPU NLP pipeline that classifies the words.

SELECTED WORK

Root4practice management for law offices.

Secure identity and RBAC, matter and client workflows, document storage and an Angular workspace, delivered as a Dockerized Go microservices platform.

CHALLENGE

Law firms want a single system for clients, matters, documents and staff access, and they want it without fragile authentication bolted onto a monolith.

SOLUTION

We built a modular platform of dedicated services on a clean-architecture Go foundation: identity and RBAC with gRPC authorization, an office domain API for clients, matters, tasks and search, S3-compatible document storage, and an Angular SPA on top.

OUTCOME

A legal practice stack shaped for production. Secure by default, it runs locally or in containers, and it can be extended without rewriting the platform core.
