About

Senior Software Engineer with hands-on experience designing and operating scalable, cloud-backed backend systems using Java, Go, and Node.js, primarily on AWS IaaS. I work closely with product, mobile, and compliance teams in Agile/Scrum environments, owning features end-to-end from design to production. Strong focus on debugging and troubleshooting production systems, performing root-cause analysis using logs, metrics, and distributed system behavior to resolve reliability, performance, and data-consistency issues. Experienced in building secure backend services, applying authentication, authorization (RBAC), API security, and multi-tenant access control patterns. Comfortable working with distributed architectures, including microservices, event-driven workflows, message queues, and both relational and NoSQL data stores. I value clean system design, operational simplicity, and continuous improvement through code reviews, iterative delivery, and post-incident learning. Open to Backend Engineer / SDE / SDE-2 roles. Happy to connect or discuss opportunities.
