Awards, certifications, patents, technical publications and industry recognition from 15+ years of engineering by Yavuz Ayhan Önder and Didivor Teknoloji.
Concrete metrics from production: p99 latency, SLO attainment, MTTR and scale factor. Every number comes from a live system and is contractually verifiable.
Re-architected provisioning pipeline as cloud-native CNFs; cut activation time from seconds to milliseconds across 38M telecom subscribers.
Moved a convergent billing core from monolith to event-sourced microservices in 6 rolling waves with dual-stack reconciliation — zero data loss.
Established GitOps + policy-as-code pipeline; cut release lead time, dropped incident MTTR by 61% and brought change-failure rate into single digits.
Kept a multi-tenant platform processing 4.2B+ monthly events in production with caching, async pipelines and query tuning; p99 stays under 80 ms on critical APIs.
Designed a central orchestrator for 4,800+ stations; load-shaping algorithms shifted demand off-peak and reduced peak grid consumption by 18%.
Certified by the Turkish Standards Institute, ISO 27001 information security and CMMI Dev/3 maturity — documenting enterprise quality and compliance (KVKK, GDPR).
