About

Backend Software Engineer with ~3 years of experience, primarily focused on building reliable, scalable backend systems in Java and Python across fintech and security domains. I have worked on designing and maintaining backend services for retail payments, POS integrations, loyalty platforms, and cloud security systems, handling high-throughput APIs, event-driven pipelines, and data-intensive workflows. My experience includes building services around points accrual and redemption, analytics, IAM integrations, and backend orchestration using Kafka, PostgreSQL, MongoDB, Redis, and Neo4j. I’ve contributed to systems deployed on AWS and GCP, worked with containerized services (Kubernetes), and collaborated closely with platform and DevOps teams. I’ve also been involved in improving deployment and infrastructure workflows using Terraform, ArgoCD, and GitOps practices, with a focus on reliability and maintainability rather than speed at all costs. My core strength lies in backend service design, data modeling, and building predictable systems that scale over time. I value clear ownership, clean interfaces, and practical system design driven by real-world constraints. Open to backend engineering roles in structured, engineering-driven environments, and always happy to collaborate or help where my experience can add value.
