Datall is a technology company delivering diverse software products, including real-time industrial monitoring, secure data transfer, and applied ML platforms. Over four years I owned backend architecture, API development, database design, and production deployment across multiple projects.

• Designed and maintained a production C++/Drogon backend serving real-time data from 100+ industrial sensors, handling millions of data points with REST APIs, WebSocket streaming, and PostgreSQL + TimescaleDB for persistent storage and time-series queries.
• Implemented a secure one-way data hub in Java using UDP networking and fiber-isolated channels, providing transparent service replication of OPC UA, Modbus, and S7 across physically separated networks with modular serialization and packet validation.
• Built a user-facing full-stack marketplace in Java with a Spring Boot REST API, SQLite database, token-based authentication, and a native Android client, covering account management, product listings, search, transactions, and admin controls.
• Redesigned the real-time streaming layer from Apache Kafka to topic-based WebSocket channels with per-client subscriptions, reducing latency and complexity while enabling efficient, targeted data delivery.
• Developed a RAG platform for legal consultation: fine-tuned embeddings, vector indexing, and retrieval-augmented query processing returning cited references.
