Software Engineer | Specialized in Scalable Distributed Systems & Full-Stack Development
- 🚀 System Design: Building Modular Monoliths and Microservices with a focus on domain-driven design.
- ☕ Modern Java: Leveraging Java 25 Virtual Threads and Spring Boot 4 for high-throughput backends.
- ⚙️ API Development: Designing robust RESTful APIs and asynchronous event-driven architectures.
- 🦀 Rust: Shipping single-binary services and apps with Axum, SQLx and Tauri (secrets vault, blog API, VPN clients).
- 🔐 Identity & Security: Building a self-hosted OAuth 2.1 / OIDC provider with PKCE, MFA, audit logs and envelope encryption.
🅰️ Frontend Engineering: Crafting reactive UIs using Angular, Signals, RxJS, SingleSPA, and Webpack.- ☁️ Cloud Infrastructure: Architecting scalable environments on AWS including EC2, S3, RDS, CloudWatch, and EKS.
- 🛠️ Ops: Running my own platform with Jenkins pipelines, Docker, encrypted per-environment config, and Prometheus / Loki / Grafana monitoring.
- 📦 Open Source: Contributing to Rust projects like notecraft and maintaining npm packages.
- Modular Monoliths: Designing encapsulated modules to ensure easy transitions to Microservices when needed.
- Microservices: Orchestrating services with Spring Cloud, Kafka for events, and Redis for state.
- Event-Driven Architecture: Implementing asynchronous communication, background processing, and robust messaging pipelines.
- DevOps: Automating deployments via Jenkins, Docker, and GitHub Actions: build → push → promote from DEV to QA, with secrets decrypted only while a pipeline runs.
- Observability: Logs and metrics with Prometheus, Loki, Promtail and Grafana, plus my own single-JAR telemetry platform.
