What we do
Six disciplines. One standard: excellence.
We take full ownership of outcomes — from the first architecture diagram to the 3 a.m. incident that never happens. Every engagement is led by senior engineers who have shipped at scale.
Web Platforms & SaaS
Multi-tenant architectures, usage-based billing, role systems, real-time collaboration. We've taken 14 SaaS products from whiteboard to first enterprise contract.
14 products launched · ARR-provenE-commerce Engineering
Headless storefronts, sub-second Core Web Vitals, search and checkout that convert. Replatforming without a single hour of lost revenue is our speciality.
Avg. uplift · +31% conversionCloud & DevOps
Kubernetes platforms, IaC with Terraform, zero-downtime pipelines, cost engineering. Our SRE practice runs client workloads at 99.99% availability across AWS and Hetzner EU regions.
SLA record · 99.99% uptimeAI Integration & Automation
LLM-powered document pipelines, retrieval systems over proprietary data, ML-driven forecasting. Pragmatic AI that ships to production and pays for itself — measured, not demo-ware.
In production · 23 AI systemsUI/UX Design
Research-driven product design, design systems that engineers love, and interfaces that make complex workflows feel effortless. Design and engineering sit at the same table from day one.

Proof, not promises.
Three engagements our clients let us talk about. The other 117 are protected by NDAs we take as seriously as our SLAs.
Real-time risk dashboard for a German private bank
We replaced a nightly batch reporting stack with an event-streamed risk engine and trader-grade dashboard — React, Kafka and PostgreSQL on Kubernetes — passing BaFin-aligned audits on the first attempt.

Methodology
A process built for zero surprises.
Fixed rituals, transparent artefacts, weekly demos. You always know what's shipped, what's next and what it costs.
01
Discover
Stakeholder interviews, domain mapping and a technical audit of anything you already run. We leave this phase with a shared definition of "done" — and a risk register, not a sales deck.
1–2 weeks
02
Architect
System design, data models, ADRs and a clickable prototype. Every architectural decision is written down, argued and signed off before a single sprint begins.
2–3 weeks
03
Build
Two-week sprints, demo every Friday, trunk-based development with full CI/CD. Code review is mandatory, test coverage is contractual, and you can read our board any time.
6–20 weeks
04
Scale & Operate
We don't hand over a ZIP file and vanish. SRE runbooks, observability, on-call rotations and a quarterly architecture review keep your platform fast as it grows.
Ongoing SLATechnology
Boring where it matters, sharp where it counts.
We standardise on a battle-tested core and go deep instead of wide. No résumé-driven development — every tool below runs in production for our clients today.

What it's like to work with us.
“
ABAR rebuilt a system our previous vendor had declared 'unfixable'. Nine months later it clears three million requests a day and our regulator signed it off first pass. They argue with you when you're wrong — that alone is worth the invoice.
“
Fourteen weeks from kickoff to a live MVP planning routes for 2,400 trucks. Their weekly demos meant our board saw progress, not promises. We've since moved our entire product engineering to ABAR.
“
The replatform paid for itself in four months — conversion is up 38% and Black Friday didn't even wake anyone up. ABAR feels like an in-house team that happens to sit in Timișoara.
