Cloud-Native Backend Engineer focused on building highly scalable, secure, and observable backend systems.

I engineer enterprise-grade backend APIs and manage the cloud infrastructure they run on. My core focus is on Java/Spring Boot architectures (Modular Monoliths & Microservices), zero-trust security using OAuth2/Keycloak, and automating everything from server provisioning to CI/CD deployments. I believe in "Day-2 Operations"—code isn't done just because it compiles; it needs to be containerized, securely deployed, and actively monitored in production.

A cloud-native, event-driven banking engine engineered from the ground up for zero-trust environments, ultra-low latency, and massive horizontal scale.

• Architecture: CQRS (Command Query Responsibility Segregation) with the Transactional Outbox Pattern to enforce strict double-entry bookkeeping constraints without distributed 2PC.
• Tech Stack: Java 26 (Project Loom), Spring Boot 4.1.0, Apache Kafka, PostgreSQL, Redis.
• DevOps & CI/CD: 100% automated GitOps pipeline using GitHub Actions to parallel-build hardened containers, pushed securely to GHCR, and deployed automatically via Argo CD onto a Kubernetes cluster.

An enterprise-grade, zero-trust e-commerce backend built with Java 26 and Spring Boot.

• Architecture: Scalable Modular Monolith using Domain-Driven Design (DDD) and Hexagonal Architecture.
• Security: Stateless security model leveraging Keycloak for custom OAuth2 JWT Role-Based Access Control (RBAC).
• DevSecOps: Hardened CI/CD pipeline via GitHub Actions deploying immutable, non-root containers with read-only filesystems.
• Observability: Fully instrumented with Micrometer, aggressively scraping metrics via Prometheus into dynamic Grafana dashboards (monitoring p95 latency & JVM memory).

A highly available 3-tier environment on AWS.

• Architected AWS infrastructure (EC2, RDS) via Terraform, reducing provisioning time by 90%.
• Containerized the application runtime using Docker and automated declarative security patching routines using Ansible.
