Case Studies

Problems solved. Results measured.

Each engagement started with an expensive engineering problem. Here's what I did about it.

Problem

Engineering throughput was constrained by platform friction, fragmented delivery workflows, and high coordination overhead.

Intervention

Platform shift centered on standardized workflows, developer experience upgrades, and measurable operating baselines.

Result

€2M+ annual savings from one platform shift.

Problem

Legacy Angular CLI monolith with 45-min builds, 4-week onboarding, and cross-team friction across a 6M-user government portal.

Intervention

Migrated to Nx monorepo workflows with reusable tooling and clearer ownership boundaries.

Result

Lead time reduced from 20 to 8 minutes. 2–4 week onboarding reduction. 20% fewer bugs. 40% faster delivery.

Problem

Critical healthcare research platform stuck on AngularJS. Full rewrite too risky. Team couldn't ship new features.

Intervention

Incremental AngularJS to Angular migration plan with CI/CD automation and parallel feature delivery.

Result

75% codebase preserved. Zero-downtime migration. Automated CI/CD. Clinical data visualization rebuilt.

Problem

High-traffic e-commerce platform with poor conversion and no testing culture. 100k daily users, revenue left on the table.

Intervention

Introduced experimentation discipline, event instrumentation, and repeatable A/B test execution loops.

Result

3x conversion increase. 40% faster QA cycles. Systematic A/B testing framework built from scratch.

Problem

Global CRM deployed across 20+ countries with fragmented operations, slow resolution times, and enterprise integration complexity.

Intervention

Standardized global CRM operating model and integration workflows across regional teams.

Result

60% faster resolution. 80% user satisfaction increase. Standardized operations across all regions.
