Backend-focused software engineer specializing in scalable systems, APIs, and cloud-native architecture.
What I'm looking for
I am a backend-focused software engineer experienced in building scalable, high-performance APIs and cloud-native systems. I specialize in Node.js and Go, and I design fault-tolerant architectures that support real-time processing and asynchronous workloads.
At Brain Station 23 I improved database performance by 55% through query optimization and implemented Azure-based solutions (Functions, Blob Storage, Service Bus, IoT Event Hub, Key Vault) that delivered measurable operational efficiency and business value. I collaborate closely with cross-functional teams to deliver production-quality features on agile sprints.
I enjoy mentoring and technical coaching, and I have a strong problem-solving track record demonstrated by extensive competitive programming practice and hands-on project work including tenant management platforms, distributed URL shorteners, and mobile games.
