Full-cycle engineering.
No hand-offs, no excuses.
One senior team owns your system from first whiteboard sketch to 3 a.m. pager duty. We take on fewer projects than we could — so every one ships at the standard we put our name on.
Web Platforms & SaaS
Multi-tenant SaaS from MVP to Series-B scale: subscription billing, role models, usage metering, admin tooling. Architected so tenant #1 and tenant #10,000 get the same latency.
E-commerce Engineering
Headless storefronts and replatforming for brands where every 100ms of latency is money. Search, checkout, and inventory pipelines tuned for Black Friday, not the demo.
Cloud & DevOps
Kubernetes platforms, infrastructure as code, zero-downtime pipelines, and observability that pages the right person before your customers notice. We cut one client's AWS bill by 41%.
AI Integration & Automation
LLM copilots, document intelligence, and workflow automation wired into real enterprise systems — with evaluation harnesses, guardrails, and EU-hosted inference. Production AI, not demos.
UI/UX Design
Interfaces for dense, high-stakes data: trading desks, logistics towers, clinical dashboards. Design systems your engineers can actually implement — pixel-specced, tokenized, tested.

Case studies with numbers,
not adjectives.

Real-time risk engine for a German private bank
Kranich Capital's legacy overnight batch left traders blind for hours. We built an event-driven risk and exposure platform on Kafka and Kubernetes: live P&L across 40k instruments, streaming margin alerts, and a React dashboard the trading floor keeps on its center screens. Audited under BaFin outsourcing rules; two years in production without a critical incident.

Fleet orchestration platform scaled to 14 markets
Helvetia Logistics ran 2,400 vehicles on spreadsheets and phone calls. We designed and built their multi-tenant dispatch SaaS: constraint-based route optimization, driver apps, customs document automation, and live telemetry ingestion at 40k events/minute. The platform expanded from Switzerland to 14 European markets without an architecture rewrite.

Headless replatforming for a fashion retailer
VELOCE's monolithic storefront collapsed under every drop campaign. In 26 weeks we replatformed to a headless architecture — Next.js edge-rendered storefront, Elasticsearch-powered search, rebuilt checkout, ERP-synced inventory. The first post-launch Black Friday ran at 11× normal traffic with zero downtime, and the numbers went to the board.

A process built for systems
that cannot fail.
Fixed phases, explicit deliverables, senior engineers only. You always know what ships next and why — from the first workshop to the first 3 a.m. alert we handle for you.

Discover
Deep-dive workshops with your domain experts. We map the business logic, failure modes, compliance constraints, and the numbers that define success — before anyone opens an editor.

Architect
System design, data modeling, and infrastructure planning — pressure-tested with throwaway prototypes on the riskiest assumptions, not slideware.

Build
Two-week sprints with weekly demos of running software. CI/CD from day one, code review on every merge, staging environments that mirror production exactly.
→ production-ready increments
→ 80%+ test coverage
→ live demo every Friday

Scale
Load testing, observability, SLAs, and 24/7 monitoring. Clean handover to your team — or a long-term partnership where we run what we built.

Boring where it should be,
sharp where it counts.
We standardize on proven, hiring-friendly technology — and reach for the exotic only when the problem genuinely demands it. Every choice is documented in an ADR you can read.

What CTOs say when
the system just runs.
ABAR replaced a team three times their size and still shipped faster. Their risk engine has processed every trading day for two years without a single critical incident. Our regulator asked who built it — that's the compliment.
Dr. Markus HellwegCTO · Kranich Capital · Frankfurt
They don't behave like a vendor. They argued us out of features we didn't need and into an architecture that scaled from Switzerland to fourteen markets without a rewrite. That saved us at least two years.
Sofia BrandtVP Product · Helvetia Logistics · Zürich
The replatform paid for itself in nineteen weeks. Numbers our board could actually see: +38% conversion, +52% mobile revenue, and a Black Friday at eleven times normal traffic with zero downtime.
