Software Engineer with 4 years of experience architecting scalable backend systems, B2B SaaS platforms, and low-level applications. Combining deep system knowledge (C++, Linux) with modern full-stack development (Java, Laravel, Vue/React) and applied Machine Learning (Computer Vision, OCR). Focused on clean OOP, containerized orchestration, and autonomous problem-solving.

Production-ready Full-Stack SaaS demonstrating scalable microservice patterns. Features real-time sync via WebSockets (Reverb), MFA (WebAuthn Passkeys, TOTP), and a dual Hybrid API (REST + GraphQL).

• Infrastructure: Architected 18 Kubernetes manifests with HPA auto-scaling, utilizing PostgreSQL, MongoDB, Redis, and RabbitMQ.
• Quality: CI/CD via GitHub Actions, k6 load testing (500 concurrent users), and comprehensive Pest testing with Codecov integration.

Comprehensive cross-platform personal finance and receipt management application combining budget tracking with AI OCR technology and German-compliant bookkeeping (GoBD/DATEV export).

• AI/ML: Multi-engine OCR pipeline (Google ML Kit, Tesseract) enhanced by YOLOv8 receipt boundary detection via TensorFlow Lite.
• Security: Hardware-backed encryption (Android Keystore/iOS Keychain) with PBKDF2 key derivation and tamper detection.
