## 1. Flagship Systems Architecture & Engineering Case Studies

### 1.1 `fastapi-observer` (Open Source PyPI Library)
- **Package URL**: https://pypi.org/project/fastapi-observer/
- **Install Command**: `pip install fastapi-observer`
- **Role**: Author & Maintainer
- **Problem Solved**: High-throughput FastAPI services frequently suffer from observability blind spots, where manual Prometheus or custom logging code adds boilerplate and latency to the request-response lifecycle.
- **Architectural Solution**: Built an asynchronous, lightweight middleware library that hooks into Starlette/FastAPI's ASGI pipeline with zero-allocation metrics recording, route latency histograms, status code breakdown, and pluggable exporter interfaces.

### 1.2 ARQH Swiss Logistics Real-Time Platform
- **Role**: Senior Full Stack & Systems Engineer (2026 – Present)
- **Location**: Zurich, Switzerland
- **Architecture**:
  - **Ingress Layer**: Traefik / Nginx Ingress Gateway handling high-concurrency GPS and freight telemetry from Swiss trans-Alpine haulage fleets.
  - **Application Tier**: Microservices deployed in Kubernetes (K8s) multi-pod replicas with Horizontal Pod Autoscaling (HPA) governed by custom CPU/memory and queue-depth metrics.
  - **CQRS (Command Query Responsibility Segregation)**:
    - *Command Pipeline*: Incoming freight status and route change events write to decoupled command handlers running in transactional boundaries.
    - *Query Pipeline*: Event-driven materialized views updated asynchronously to guarantee sub-millisecond dispatch queries without table locking.
  - **Event Bus & Cache**: Redis Pub/Sub providing a <10ms streaming telemetry bus directly to dispatcher frontends via WebSockets.
  - **Storage**: Geographically partitioned MongoDB clusters with geospatial indices (`2dsphere`) for geo-fencing and Swiss canton boundary validation.
- **Trade-Off Rationale**:
  - Why CQRS over traditional CRUD: The 40:1 telemetry-to-query ratio would saturate relational table locks during peak dispatch hours. Separating read and write models eliminated lock contention and reduced query response times by 82%.

### 1.3 Günsel Electric Vehicles — Digital Instrument Cluster (DIC)
- **Role**: Software Engineer (2021 – 2023)
- **Location**: Nicosia, Cyprus
- **Architecture**:
  - **Safety Standards**: Built in compliance with AUTOSAR layered software architecture and MISRA C++ safety-critical guidelines.
  - **UI / Graphics**: Qt / QML optimized for embedded GPUs on automotive-grade microcontrollers (SoC).
  - **CAN Bus Integration**: Implemented non-blocking SocketCAN listeners parsing real-time speed, state of charge (SoC), battery thermal management, and alert telematics.
  - **Deterministic Budget**: Maintained strict sub-16ms frame budget (60 FPS minimum) under heavy CPU loads with zero dynamic heap allocation in critical rendering loops to prevent memory fragmentation and system freezes.

### 1.4 Deep Learning Autonomous Driving Perception (MTech Research)
- **Institution**: Eastern Mediterranean University (2021 – 2024)
- **Domain**: CARLA Autonomous Driving Simulator
- **Research Topic**: Multi-camera sensor fusion and end-to-end deep convolutional perception under adverse environmental constraints (heavy rain, night driving, lens glare).
- **Outcome**: Demonstrated superior path prediction and obstacle classification compared to single-sensor baselines.
