At Daktela, I develop backend APIs for omnichannel communication workflows and introduced automated OpenAPI specification generation for custom APIs. I also investigate production performance bottlenecks, including slow database queries and customer PBX deployments.
At IceWarp, I led backend development of a licensing and subscription management system, shaping activation, billing, and license validation workflows. I built REST APIs for internal systems and partner integrations, and developed Vue.js admin interfaces.
