We Don't Build Software. We Engineer Impossible Solutions.
Lead/Principal+ engineers who thrive when projects get hardest. When complexity breaks other teams, we get started. When legacy systems seem impossible, we deliver.
When Projects Get Impossible, We Get Going
Most software teams walk away when complexity explodes. 20-year-old banking systems too tangled. 10,000+ TPS performance requirements impossible. Zero-downtime migrations of critical systems too risky. DRM systems without internet connectivity? Impossible. That's exactly when we excel.
In specific projects, we've replaced 20-year legacy banking platforms processing 2-4 million daily transactions with no customer-visible downtime during cutover. Architected big data systems handling 10,000+ peak TPS while cutting infrastructure costs by around €180k/year. Built PlayReady DRM streaming platforms working without internet on ships mid-Atlantic. Implemented TensorFlow ML automating about 70% of customer service. Deployed Kubernetes in production since 2014 - before it was mainstream.
We solve the problems others won't touch. Deliver results others can't achieve. Stay committed when complexity sends other teams running.
Technical Mastery
Production-proven expertise: Kubernetes (since 2014!), Big Data, PlayReady DRM, TensorFlow ML, Zero-Downtime Architecture
Unstoppable Under Pressure
Migrated core banking systems during €90M jackpot weekends with no customer-visible downtime and no known lost transactions in those projects.
Proven Performance
100x query performance. 50% cost reduction (€180k/year savings). 70% automation. 10,000+ TPS. Sub-200ms P99 latency.
We Never Quit
4-year aviation platform. Zero-downtime banking migrations. We stay until victory is complete and sustainable.
How We Engineer Success
- 1 Deep technical analysis: We understand your architecture, bottlenecks, and business constraints
- 2 Battle-tested architecture: Cloud-native, zero-downtime, cost-optimized from day one
- 3 Relentless execution: Measurable daily progress, transparent metrics, zero excuses
- 4 Long-term commitment: We stay through deployment, optimization, production hardening, and success
The Macstab Method
Four pillars proven across banking & finance, insurance & healthcare, energy & utilities, aviation & transport, lottery & gaming, logistics, retail & e-commerce, and enterprise platforms
Cloud-Native Excellence
Kubernetes since 2014. GKE, AWS, Azure, OpenShift. Auto-scaling architectures delivering 50% cost reductions while handling 10,000+ TPS. Elastic scaling from zero to peak instantly.
Zero-Downtime Mastery
Migrate 20-year banking systems. Replace monoliths with microservices. Deploy during peak traffic. All with zero seconds of downtime. Nginx failover, dual-write patterns, gradual extraction - we've done it all.
Extreme Cost Optimization
€180k/year infrastructure savings on one project alone. 50% cost reduction via elastic GCP scaling. 40% savings through PostgreSQL migration. We make systems faster AND cheaper.
Production-Grade Code
Clean, maintainable, documented code built for decades. PostgreSQL partitioning handling millions of transactions. JPA lazy-loading optimization. Distributed replication over satellite networks. Real engineering.
Technologies We've Mastered in Production
Not theory. Not courses. Production systems at scale serving millions of users with real business impact.
When Others Quit, We're Just Getting Started
What separates typical consultants from elite engineers who deliver impossible results
Typical Consultants
- ✗ Walk away when legacy systems get too complex
- ✗ Promise performance, deliver excuses
- ✗ Leave technical debt and poorly documented code
- ✗ Vanish after deployment when real challenges emerge
- ✗ Optimize for billable hours, not business outcomes
Macstab Engineering
- ✓ Specialize in impossible legacy modernizations - 20-year systems are our specialty
- ✓ Deliver proven results: 100x performance, 50% cost cuts, 10,000+ TPS, practically zero downtime in key projects
- ✓ Leave production-grade code: PostgreSQL optimization, sophisticated JPA, distributed replication
- ✓ Stay committed: 4-year projects, near-zero-downtime migrations in specific cases, production hardening until success
- ✓ Obsessed with measurable business impact: €180k savings, 70% automation, and a move from 2-week release trains to continuous delivery in our documented case studies
