Technical strategy with a business edge
Software architecture and system design for products that need to move fast.
How I help
MVP and technical direction
“I need a senior technical guide to design and deliver an MVP, including AI from pilot to production.”
Scale a system in production
“I need to know whether the system will hold under real load and what has to change before it breaks.”
Integration across different organizations
“I need a clear boundary between our systems, without creating a dependency we cannot get out of later.”
Selected work
Retail, backend modernization
Replacing a backend without stopping 2,600 stores
The constraint was to replace the backend in place while keeping 2,600 stores and 9,500 terminals running. The migration handled 150 million documents and 1 TB of data, delivering a 79% throughput gain and a 216x query-time reduction.
Luxury e-commerce
One architecture across three cities
The choice was one shared architecture for a luxury brand across Berlin, Geneva, and Shanghai, with local compliance and localization constraints built into the design. It kept teams aligned across time zones and preserved delivery momentum.
Mobility & traffic management
18 microservices on AWS
The constraint was multiple national traffic feeds, each with a different schema and update cycle. The platform absorbed HERE, TomTom, and Radio24 without imposing a single-source model, and has run in production since 2017 with more than 99.9% uptime.
Public sector
Architecture while requirements were still moving
Requirements were still forming, so the architecture had to move while the main bottlenecks were being identified. The system grew to 400,000 entities and handled peaks of 9 million calls per hour before a wider modular redesign.
Enterprise content
Headless CMS for Content as a Service
The choice was a single API contract for Crownpeak while hundreds of clients depended on the same content layer. The separation made the system reusable without forcing each client into bespoke integration.
Open source platform
Ten years of evolution without rewrite
RESTHeart evolved through major upstream changes while preserving a stable product and API. Unisys and Northrop Grumman were among the organizations using the open source platform as it grew into a hosted SaaS offering.
