I’m a backend engineer specializing in distributed systems and real-time infrastructure, with 4+ years building high-throughput, low-latency services using Kafka, Go, Node.js, and AWS. I’ve worked on systems handling 1 million+ daily events and 500K+ voice interactions.

At Acefone, I led the migration from monolith to microservices, cutting infrastructure costs by 55%. I architected Kafka-based event-driven processing for 1 million+ daily events and optimized critical Go and NestJS APIs, improving average response time by 40% under peak load.

I also configured AWS API Gateway for routing, authentication, and rate limiting across 15+ microservices, and refactored the React.js/Next.js build pipeline to reduce deployment time by 60%. On the Voice AI side, I developed a real-time system integrating STT, TTS, and LLM orchestration using Pipecat and LiveKit to deliver low-latency voice interactions over telephony and WebRTC, while maintaining Asterisk PBX call routing for 500K+ daily calls at 99.9% uptime.

Previously at Orufy Technologies, I consolidated 4+ projects into monorepos with Turborepo and Nx, reducing CI/CD build times by 35%. I built product tooling like a visual bot builder (React Flow) 70% faster and a drag-and-drop email builder that lowered design time by 40%, led a team of 5 delivering 5+ production applications, and implemented hybrid server/serverless on AWS Lambda to cut infrastructure costs by 30%.
