At Guesty, I own backend features in the property-management domain, from design and development through deployment, monitoring, and global rollout. I’ve also led the decomposition of domain logic from a monolith into microservices.

I designed and developed a guest invoicing service for automated invoice generation, delivery, and compliance across international markets. I also delivered SAML 2.0 SSO integration for enterprise clients and integrated Airbnb, Booking.com, and HomeAway.

At eSign, I designed and built platform-layer APIs from the ground up, helping scale the product to 2M+ registered users, 10M+ file uploads, and 1M+ signed documents. I architected secure PDF-signing microservices using AWS CloudHSM and Sectigo certificates.

At eSign, I implemented distributed tracing and production visibility with OpenTelemetry and Grafana Cloud, and improved database performance through MongoDB aggregation pipeline optimization and Redis caching. Earlier at Kwebbl, I built backend APIs and Node.js authorization microservices for a VoIP platform.
