At Nebeus / Money-4 Limited, I improved payout reliability across event-driven microservices with concurrency-safe locking, bounded retries, automated recovery, and alerting. This reduced payout-related support cases by ~90%.

I also owned onboarding and KYC flows across internal services, Sumsub, and Zoho CRM. Automated re-KYC, consistent user data, and antifraud blocking made operational workflows ~10× faster.

At DataArt, I designed and developed a Kotlin/Spring service for promotion invoicing, integrating aggregated purchase and promotion data into an existing distributed platform. I also configured AWS Lambda infrastructure and observability for music-usage data ingestion.

Earlier, at Wrike, I built real-time propagation of task and project changes across dependent entities. Across my backend work, I’ve contributed to production systems in fintech, payments, SaaS, and enterprise platforms, from technical design through implementation and production support.
