What I'm looking for

I'm open to relocation and travel, and I'm looking to build scalable backend and cloud systems where I can improve performance, reliability, and cost efficiency while mentoring engineers.

At VimblyGroup, I rebuilt the Inbox system to reduce response times by about 95% and redesigned OpenSearch ingestion to index 1M records in 6 minutes instead of 240.

I've led end-to-end AWS CDK migrations, built reusable IaC patterns and CI/CD guardrails, optimized databases with over 1B records, and reduced cloud spend by 25% while improving reliability and scalability. I also migrated a core service from PHP to Node.js and introduced New Relic monitoring for faster incident resolution.

Previously at Trufla and CodeCube, I built multi-tenant SaaS, BPMN workflows, serverless integrations, and backend systems for insurance and food-delivery products. I enjoy mentoring engineers, reviewing code, and building practical distributed systems that perform at scale.

Rebuilt the entire Inbox system, reducing response times by ~95% through architectural redesign and performance optimizations. Re-architected the OpenSearch ingestion pipeline from DMS+Kinesis to Debezium+MSK (Kafka), cutting indexing time for 1M records from 240 minutes to 6 minutes (40x faster), and eliminating the bottleneck where large runs previously blocked new indexing.
