When the catalog is huge and the cart still has to be fast.
Large-catalog commerce breaks in specific, expensive ways: slow storefronts, brittle checkout, shipping integrations that fail at the edges, and product data nobody trusts. Bonvo has spent years fixing exactly these.
The problem
Where retail platforms bleed revenue
A 100,000-plus-SKU catalog that has become slow to browse and painful to maintain.
Checkout and cart flows that leak conversions at every step.
Multi-carrier shipping that works — until a specific carrier, region, or edge case.
Product data that's dirty, duplicated, and eroding trust in search and merchandising.
What Bonvo brings
What Bonvo brings
Performance & scale
SEO and speed systems, landing-page optimisation, and architecture that keeps a six-figure-SKU catalog fast to browse and cheap to run.
Checkout & conversion
Complete checkout-page reworks and cart refactoring for UX and conversion — the flows where revenue is actually won or lost.
Integrations & data hygiene
Universal multi-carrier shipping (DPD, MPL, GLS, Gebrüder Weiss) and automated data-cleaning systems that keep the catalog trustworthy.
Track record
Grounded in large-scale commerce
Four years building and maintaining a Magento platform on a 130,000-product catalog: an automated data-cleaning system for the full SKU set, universal multi-carrier shipping integration, an SEO speed-improvement system, landing-page optimisation, and a total checkout-page rework with cart refactoring. Plus a cross-platform PWA newspaper with built-in subscriptions and payments.
What colleagues say
Gergely is a helpful and enthusiastic workmate who I liked to work with. He always provided details and scenarios for the manual testing so we always had enough information about the changes. Very communicative, could discuss about any issue effectively. He had ideas how to upgrade the work progress and implemented several methods which made our work easier. Fast and reliable person, demanding in his work, so easy to cooperate with him. Just some examples where he made outstanding work: checkin system refactoring, remaking Lucene/PyLucene and Celery based processes, frontend, design, logging fixes, setting up OpenReplay, PostgreSQL operations, admin interface modifications, SSO authentication, metadata handling and so on. I recommend him highly and hope to work with him again in the future.
The practice scales
One architect accountable. A team when the job needs it.
Bonvo is led hands-on by one senior architect. But you are never limited to one pair of hands: the practice scales a vetted senior team up to the size a job requires — and back down when it's done — without ever changing who owns the outcome.
One accountable owner
Every engagement is owned end to end by Gergely Kovács — the architect who does the work, commands the incident, and signs off on the result. That never changes.
A senior bench, on demand
When a build needs more hands, Bonvo assembles a vetted team of senior engineers scaled to the job — from a solo rescue to a full squad — and stands it down when the work is done.
No bench-warming, no dilution
You pay for the size the problem needs, not a fixed team. The standard stays senior; the outcome stays owned by one person.
