Proof

Useful proof is not a polished screenshot. It's the path from chaos to software you can operate and change after launch.

Proof across domains

Pressure, delivery, result

Marketplace sync

Marketplace operations and product synchronization

Tens of thousands of products, large vendor feeds and category changes were crossing channels with too much manual cleanup.

Result

Operations can see what moved, what changed and what needs attention before customers notice drift.

What shipped: Structured feed parsing, delta sync, taxonomy and parameter mapping, adapter-based marketplace flows and visible failure handling.

Structured knowledge

CMS, content platforms and knowledge systems

Expert content needed stable identity, multilingual structure and machine-readable meaning across public product surfaces.

Result

Knowledge behaves like a maintained product surface, not a loose pile of pages.

What shipped: Public projects such as 555 EUCRiders with JSON-LD, Turtle, Pagefind search, stable entities and multilingual publishing checks.

Modernization

Modernization, infrastructure and rescue work

The system still worked, but Rails, frontend tooling, queues and infrastructure made every change harder to price.

Result

The system can change again without turning every request into rescue work.

What shipped: Rails 8 upgrade work, React/Vite migration, SolidQueue and Action Cable flows, PostgreSQL tuning and Linux/NGINX/Puma cleanup.
