Custom Software Development
Mission-critical systems built from a blank page: trading engines, risk platforms, internal tooling that runs entire departments. We own the hard 20% other vendors avoid.
SOFTWARE ENGINEERED TO ENDURE.
ABAR Service is an elite product engineering studio in Timișoara, Romania. Since 2015 we have designed, built and operated mission-critical platforms for enterprises in 12 countries — banks, freight networks, retail groups. EU-based. Senior-only. Zero-drama delivery.

What we do — and refuse to do badly
Six disciplines.
One standard.
Web Platforms & SaaS
Multi-tenant SaaS from MVP to Series-B scale. Billing, RBAC, audit logs and SSO done right on day one — not bolted on in year two, when it costs ten times more.
E-commerce Engineering
Headless storefronts and checkout flows engineered for conversion. Sub-second LCP at Black-Friday traffic — measured, load-tested and contractually guaranteed.
Cloud & DevOps
Kubernetes, Terraform and pipelines that deploy forty times a day without drama. FinOps included: our clients' AWS bills go down after we arrive, not up.
AI Integration & Automation
LLM features that survive contact with production: retrieval pipelines, evaluation harnesses, guardrails. Automation measured in saved FTE-hours, not conference demos.
UI/UX Design
Design systems and interfaces for dense, expert-facing products. We make complexity legible — dashboards that professionals stare at for eight hours a day.

Case 01Fintech / Frankfurt, DE2023—24
Kontowerk — real-time risk console for a German private bank
A decade of Excel-and-email, replaced by one screen.
We rebuilt portfolio risk reporting for 240 relationship managers as an event-sourced, real-time platform: sub-second aggregation across every position, a BaFin-grade immutable audit trail, and zero tolerance for stale numbers. Delivered in nine months, running untouched through three audit cycles since.

TransCargo OS — dispatch & routing SaaS for a pan-European freight network
1,400 vehicles. Nine countries. One dispatch brain.
From whiteboards and phone calls to ML-assisted load matching: we shipped a working MVP in eight weeks, then scaled it into the operating system of the whole network — route optimization, an offline-first driver app in six languages, and live ETAs customers actually trust.

Meridian Retail — headless replatforming for an 11-market fashion group
Monolith to headless in seven months. Zero downtime cutover.
Eleven storefronts moved off a straining monolith onto edge-rendered headless commerce, with checkout rebuilt from first principles. LCP fell from 2.1s to 0.6s; on the first Black Friday the platform absorbed 14,000 orders an hour without a single incident.

08Testimony
In their words, on the record
ABAR rebuilt in nine months what two previous vendors couldn't stabilise in three years. The regulator's audit went through without a single finding.
Markus Weidel
Chief Technology Officer
German private banking group
They think like owners. Every sprint demo shipped something our dispatchers were actually using the next morning. I've never seen that from an external team.
Ingrid Solheim
VP Operations
TransCargo Group, Rotterdam
The replatforming paid for itself before the project even closed. A 38% lift in conversion is not a rounding error — it changed our board's growth plan.
