What I'm looking for

I seek roles where I can architect scalable cloud-native systems, lead backend or Web3 initiatives, mentor engineers, and deliver measurable reliability and performance improvements in collaborative, engineering-driven teams.

I am a Senior Software Engineer with 8+ years building scalable, high-performance web and cloud applications across SaaS, telecommunications, and Web3 ecosystems.

I design distributed systems, API architectures, and automated workflows that reduce latency, improve reliability, and increase developer productivity.

I have led cloud-native backend development, implemented AI-driven anomaly detection, and engineered microservices and data ingestion pipelines to handle large-scale telemetry and test results.

I champion automated testing, CI/CD, infrastructure-as-code, and mentoring engineering teams to deliver robust, production-grade software with measurable business impact.
