The Payzon certified 227 employees on Claude Code, then came back for a second cohort.
The Payzon, a micro-banking and payments platform, ran two cohorts of Sthuthi's Claude Code track at Practitioner level for engineers across its payment processing, fraud detection and API integration divisions. After the first cohort, Payzon reported faster code reviews and higher test coverage, and booked a second.

"Partnering with Sthuthi Tech to certify our engineering organization on Claude Code transformed our delivery pipeline faster than any tool rollout we’ve attempted before. The structured hands-on approach didn't just teach syntax—it reshaped how our teams architect, refactor, and review payment microservices daily. We saw immediate uplift in developer velocity and code quality right out of Batch 1, which made expanding the certification to our remaining core teams an easy decision."
Marcus Vance · Vice President of Engineering, Payzon
Who took part
- Mid to senior software engineers
- DevOps engineers
- QA automation leads
- Systems architects
From the core payment processing, fraud detection and API integration divisions, at the Claude Code Certified Practitioner — Sthuthi Technologies' independent credential.
Focus
- Repository-level implementation and architecture
- Refactoring and debugging
- Testing and code review
- Controlled use across production payment systems
When
- Cohort 1 · 125 people
- 14 March – 8 April 2026
- Cohort 2 · 102 people
- 12 May – 6 June 2026
Each cohort followed the track's standard format: instructor-led sessions on real code, then a proctored, task-based assessment reviewed by a human assessor before a credential was issued.
What changed, according to Payzon
A 35% reduction in code review turnaround times on active payment gateway microservices, within 30 days of the first cohort finishing.
A measurable rise in test coverage across the same services.
These results were reported to us by The Payzon, which authorised their publication. Sthuthi did not run the measurement, and results depend on each team's starting point.
Why they came back
Payzon expanded to a second cohort after the first delivered faster code reviews and higher test coverage across its payment gateway microservices.
