Full-Stack Engineering
Production web apps and APIs, built with modern, maintainable foundations.
- React & Next.js + TypeScript frontends
- Node & Python APIs, GraphQL / REST
- PostgreSQL, Redis & event-driven data
- Design systems & accessibility (WCAG)
We build software that thinks and scales.
Just two senior engineers who build the whole thing themselves. We take your idea from a blank page to a live product — without the overhead (or the runaround) of an agency.

In-house expertise
What we do
Three disciplines, one team
We cover the full path from idea to scaled product — so you don't have to coordinate three separate vendors.
AI & Machine Learning
LLM features and ML systems that are useful in production — not just demos.
- LLM apps, RAG & semantic search
- AI agents & workflow automation
- Fine-tuning & model evaluation
- Guardrails, observability & cost control
DevOps & Cloud
Reliable infrastructure and pipelines so you can ship daily with confidence.
- AWS / GCP, infrastructure as code
- CI/CD with GitHub Actions
- Docker & Kubernetes orchestration
- Monitoring, scaling & cost optimization

Real Estate Platform
A large real-estate platform currently in active development — built to raise the bar above Romania's current market leaders. More to share soon.

How we work
From blank repo to production
A simple, transparent process with fixed milestones and weekly demos — so you always know exactly where things stand.
01
Discover
We pin down goals, scope, and architecture — then give you a clear plan, timeline, and fixed milestones.
02
Design
UX flows, a reusable design system, and clickable prototypes so we validate the experience before writing features.
03
Build
Iterative delivery with weekly demos. You always have a working build and a direct line to the engineers building it.
04
Ship & Scale
Automated deploys, monitoring, and performance tuning — plus ongoing support as the product grows.
The stack
Production-grade tooling across the whole stack — with security built in, not bolted on.

The team
Two founders, no middle layer
We kept the team deliberately small, so you work directly with the people building your product instead of an account manager.
Sebastian Constantin
Co-founder · Full-Stack & AI
Full-stack, but leans into AI — LLM and RAG features, plus the Next.js apps they plug into.
Full-StackAI/ML
Denis Mateescu
Co-founder · Full-Stack & AI
Mostly on the ML and data side: model integration, evaluation, and the APIs that serve the results.

FAQ
Questions you might have
No jargon — just honest answers about how we work and what it's like to build something together.
I'm not technical — can you still help?
Definitely. Most people we work with aren't developers. We handle the technical side and explain things in plain language, so you always know what's going on and why.
How do we get started?
We start with a quick, no-pressure chat about what you have in mind. If it feels like a fit, we send a simple plan with a timeline and a clear price — no surprises.
Can you work with what I already have?
Yep — an existing site, a half-finished project, or a specific tool you like. We'll pick up from where you are instead of making you start over.
Who will I actually be talking to?
Us — the people building it. No account managers, no call centers. You get a direct line to the engineers doing the work.
Do I own everything you build?
100%. The code, the design, the accounts — it's all yours. No lock-in, and we hand everything over whenever you want.
How much does it cost?
It depends on what you need, but we always agree on a clear price up front before any work starts. Send us a message and we'll give you a straight answer.
