# odoo-dev.org - Oleg Zubak, independent Odoo architect and developer

> Odoo consulting, development and migrations for small teams. Free half-hour consultation: which modules you need and which you don't.

Independent Odoo architect and developer, registered as a sole proprietor in Ukraine. One engineer from the first call to production: the person who estimates the work writes it and ships it. Odoo versions 15 to 19, for small teams in the European Union, the USA and Asia.

Working languages: Ukrainian, Russian, English, Romanian.

## Services

- **Performance and audit**: Slow queries, heavy front end, Core Web Vitals. Measured first, changed second. Elasticsearch beside Odoo where PostgreSQL stops being enough.
- **Version migration**: Architecture review and migrations 15 → 19 with your own data and custom modules. What breaks is found on staging, not on the live system.
- **First implementation**: Data model, roles, reports and integrations - up to a system people actually work in.
- **Modules and customisation**: A new module or a change to an existing one, including third-party ones.
- **Integrations**: Payment services (Paddle), search (Elasticsearch), custom and third-party HTTP APIs.

## Writing

- [Odoo partner or independent developer: what the difference actually is](https://odoo-dev.org/blog/notes-on-odoo-1/odoo-partner-or-independent-developer-what-the-difference-actually-is-5): What an Odoo partner status certifies: ten, seventy-five or three hundred new Enterprise users a year, certified staff, retention.
- [Odoo in production: what holds, what breaks, what is not in the manual](https://odoo-dev.org/blog/notes-on-odoo-1/odoo-in-production-what-holds-what-breaks-what-is-not-in-the-manual-4): Experience with Odoo in production: 110,000 products in one catalogue, forty storefronts on one instance, search from eight seconds to one.
- [Odoo, Salesforce, HubSpot, SAP: what a team of ten actually pays](https://odoo-dev.org/blog/notes-on-odoo-1/odoo-salesforce-hubspot-sap-what-a-team-of-ten-actually-pays-3): German list prices for a team of ten: Odoo Custom €46.80 per user, HubSpot €90 plus €1,470 onboarding, Salesforce €195, SAP by quote only.
- [Forty websites in one Odoo instance](https://odoo-dev.org/blog/notes-on-odoo-1/forty-websites-in-one-odoo-instance-2): Forty shops on one Odoo: one catalog, one deploy, forty domains and themes. What each site keeps to itself, why the shared worker pool is the real limit.
- [Search on 110,000 products took eight seconds. Now it takes one.](https://odoo-dev.org/blog/notes-on-odoo-1/search-on-110000-products-took-eight-seconds-now-it-takes-one-1): Faceted catalog search in Odoo took eight seconds on 110,000+ products.
