Revamped Hybrismart: Engineering a Smoother E-Commerce Blog Experience | June 29 2026, 03:45

I completely redesigned and refreshed my hybrismart – an engineering blog about ecommerce. Yes, as you’ve gathered from this introduction, it’s in English. All 200+ articles have been revamped; no more style zoo, the font is easier on the eyes, illustrations are clickable, and there is now in-article navigation. It’s not perfect yet, but it’s enough to go public.

Search will be available. It’s already operational, but I temporarily hid it. Just need to finish it up.

A particular point of pride is the contextual article recommendation system. That is, next to a paragraph about drools, there will be a link to an article about drools explaining why it’s relevant in that context. On desktop, this will appear as a margin note, and on mobile, it will be an inset in the text.

The entire site is static and generated from markdown. Goodbye WordPress, you were very, very bad.

Migrating SAP Commerce Content with Graph Databases: A Neo4j and Memgraph Guide | June 10 2026, 03:12

Published a new article on Hybrismart after a long hiatus. It’s about how to migrate data from an old site to a new one using a graph db (specifically, I used neo4j and memgraph). The case is as follows: there is an old site and a new site, and you need to transfer CMS data – components, pages, layout from the old to the new, while along the way making various transformations – for example, in the new site the styles are different, the layout is different, some of the components are different. For this task, I used a graph db.

It’s been a while since I wrote on my blog about SAP Commerce Cloud. I worked at SAP for two years, and thought it inappropriate to write about their products while formally having access to internal documents. Currently, I am working on two projects simultaneously – one about migrating SAP Commerce Cloud, and the other significantly about graph databases. At the junction of these worlds, the article was born.

Tesla vs. Gasoline: Analyzing Fuel Costs in 2025 | February 26 2026, 04:07

We bought a Tesla in mid-2025 – comparing gasoline costs to electricity costs.

Looking just at charging the Tesla, the stats are separate. Since buying, we’ve used 5000 kWh costing $738 – covering 13,550 miles. Meaning, traveling 18 miles (28 km) costs one dollar. On a Toyota RAV4, one dollar spent at the gas station gets me 10 miles (16 km).

Hidden Costs in Restaurant Menus: The Reality of Operational Charges | November 23 2025, 23:33

The restaurant is very tasty, but I increasingly notice that establishments include a certain percentage on top of the menu prices in the bill. In this menu, the cost of a dish is listed as $30 per plate, plus a note like this. In this case, it’s a 4% operational charge. Then there are taxes on top of that, plus another 20% for tips. As a result, $30 from the menu turns into at least $40.
