November 2025: updated technology rating from TrueIndex

Project news
November rating analysis
Key takeaways
What is next?

It is already early November, and my parsers collected fresh data a while ago. Today I am sharing an analysis of the rating update and project news.

#Project news

#New technologies

This month we added several technologies:

Fortran, ClickHouse, RabbitMQ, Kafka

#Technology moves

Qt was moved from libraries to frameworks.

#Removed technologies

Ant Design was removed from the rating.

#Parser improvements

The main improvement this month is a complete parser rework. We significantly reduced the percentage of irrelevant vacancies that get into the analysis. The filtering algorithm became smarter:

It recognizes the context of a technology mention in a vacancy description better;
It reduces the impact of accidental matches by name;
It improves rating accuracy.

Expect even bigger parser improvements in the coming month.

#FAQ improvements

In the "Frequently Asked Questions" section, we described the rating methodology in more detail:

How data is collected (HeadHunter, Habr Career);
How statistical normalization is applied (Z-score);
How the final score is calculated (3-50 points).

#Programming languages

Go moved 3 points up. I heard your feedback about Go, and after updating the parser I changed the search term from golang to go.

JavaScript overtook C - JS took 4th place, pushing C down to 5th.

Top 10 languages:

SQL
Python
1C
JavaScript up

TypeScript up
C# down
Go up up up

#Libraries and packages

Jackson moved up by 16 points!

caret dropped by 24 points!

#Databases

PostgreSQL is the leader among relational databases;
MongoDB remains relevant for NoSQL tasks;
Redis has strong demand for caching and real-time applications;
ClickHouse (new) shows growing demand for analytical databases.

#DevOps and cloud

Docker remains the containerization standard;
Kubernetes keeps developing actively;
AWS is the leading cloud platform in Russia;
RabbitMQ (new addition) is a stable alternative to Kafka;
Kafka (new addition) shows growing demand for stream processing.

#Key takeaways

The parser became more accurate - this month's results are more reliable thanks to the improvements.

#What is next?

Parser optimization - further improvements to vacancy filtering;
More metrics - additional metrics are planned for a fuller picture.
