TECHNICAL PROJECTS

Java Backend Architecture & Custom REST API
Stack: Java, JDBC, H2, JUnit, Mockito, SOLID Patterns
• System Architecture: Designed a modular MVC application adhering to SOLID principles and using
the Repository Pattern for clean separation of concerns.
• Engineering Deep-Dive: Implemented a raw REST API with manual JSON parsing (no frameworks) to
master core HTTP mechanics and status code handling.
• Quality Assurance: Achieved high test coverage using JUnit and Mockito to mock database layers and
validate business logic.

CI/CD Pipeline & Distributed Infrastructure
Stack: GitLab CI, Docker Compose, Nginx, Linux (Bash)
• Pipeline Automation: Built a multi-stage GitLab CI pipeline (Test → Build → Docker → Deploy)
enforcing separate workflows for Staging and Production environments.
• Infrastructure as Code: Configured Nginx as a reverse proxy with path-based routing to serve distinct
Go and Node.js microservices.
 • Deployment Strategy: Developed idempotent Bash scripts for zero-downtime releases using
timestamped versioning and symlink switching.

Secure Enterprise Network Infrastructure
Stack: OPNsense, OpenSSL (PKI), Wireshark, Linux
• Network Security: Configuration of OPNsense firewalls, DMZ segments, and Intrusion Detection
Systems (IDS).
• Cryptography: Established a private Certificate Authority (CA) using OpenSSL to secure internal
communication via mutual TLS.

Telegram Memorial Service Bot & Payment System
Stack: Python (AsyncIO), Aiogram, PostgreSQL, Docker
• Product Engineering: Developed a fully asynchronous bot handling complex user state machines and
payment processing.
• Database Performance: Engineered a non-blocking database layer using SQLAlchemy (Async) and
PostgreSQL.
• Containerization: Full Docker deployment to ensure environment consistency.
