Structured programs for teams and companies that need their engineers to understand databases, APIs, and server architecture — not just follow tutorials.
Get in touch
A practical course for managers, product owners, and analysts who work with developers daily but struggle to follow technical conversations.
Hands-on training for non-developers who need to work with third-party APIs, configure integrations, and troubleshoot connection issues without calling a developer every time.
A course for product managers, analysts, and team leads who want to understand how database design affects what is possible in a product, and how to have smarter conversations about data architecture.
For engineering managers, CTOs at small companies, and senior product leaders who need to make infrastructure decisions without being hands-on developers themselves.
A focused course on web application security for product managers, compliance officers, and business owners who need to make informed decisions about data protection without writing code.
When companies send engineers to Certmat Rixia programs, the requests cluster around a few recurring gaps. REST API design comes first — most teams can write endpoints but struggle with versioning and error contracts. Database indexing and query planning follow closely. Security practices, particularly around authentication tokens and input validation, rank third. These aren't abstract subjects; they're the gaps that cause production incidents.
These are notes from engineers and team leads who went through Certmat Rixia programs. No percentages, no dramatic claims — just what changed in how they work.

Team lead
The database module was the most useful thing I'd done in a long time. I went back to a query I'd written six months earlier and rewrote it in about twenty minutes. It now runs in under 40ms instead of taking several seconds. The difference wasn't magic — I just finally understood what the query planner was doing.
Back-end engineer, Kharkiv
I enrolled two of my engineers in the API design program because we kept having arguments about how to structure endpoints. After the program, the arguments stopped — not because everyone agreed, but because we had a shared vocabulary. Code reviews got faster and less emotional.
Team lead, product company
I was skeptical about doing structured learning after years of just reading docs and Stack Overflow. What surprised me was how the quiz format forced me to articulate things I thought I already knew. Several times I got questions wrong on topics I assumed were solid. That was uncomfortable but genuinely useful.
