Re-architected and stabilized the main Apache Flink pipeline (UDE STR)

Senior Software Consultant Java Kafka Apache Flink ...
Senior Software Consultant
  • Re-architected and stabilized the main Apache Flink pipeline (GDC) in the Unified Data Ecosystem (UDE STR) to handle multi-GBps vehicle telemetry traffic.
  • Replaced an unstable Flink SQL implementation with a production-grade Flink Streaming API, rewriting 10k+ LOC.
  • Delivered end-to-end large message ingestion (up to 64 MB), cold storage integration, and package merging, enabling seamless data migration across pipelines.
  • Drove core architectural decisions, decoupled Flink configurations from the Kubernetes Flink Operator, added DFS support for Azure ADLS Gen2, and defined DevOps procedures for upgrading Flink in production. The pipeline has been rolled out globally (EU, US, CH), replacing legacy systems.
  • Major Java backend and REST API changes, including validation layers and integration endpoints, to support new streaming and migration workflows.

LEAD JAVA DEVELOPER
  • Internet of Things (IoT) platform for smart cars, where customers received an OBD adapter with an integrated SIM card.
  • Designed and implemented scalable streaming processing flows, payment systems, concurrent socket-level Point of Sale (POS) integrations (e.g., one-click mobile fueling), code quality standards, code organization processes, and application-wide health monitoring. Established the initial infrastructure for data collection and analytics.
  • Designed and implemented a production integration with a T500 fuel station network. Developed a white-label API for key partners, including Mercedes-Benz and bp, currently operating in production. The system demonstrated high scalability, handling 300+ clustered fuel stations on a single multithreaded daemon.
  • Developed the initial fleet management web application and a fuel station simulation web tool for business demonstrations and partner integration.
  • Proposed and led the transition from a Node.js-based architecture to Apache Flink for real-time stream processing with Apache Kafka. This migration delivered improved traceability, performance, scalability, and maintainability, supporting approximately 215% more devices on the same hardware compared to the previous Node.js infrastructure (which was limited to ~18,000 devices).
  • Since 2018, served as Lead Java Developer, managing a team of five engineers. Responsibilities included real-time trip processing (map matching, road classification, overspeed detection) and data classification and prediction (e.g., fuel consumption for vehicles with noisy or incomplete measurements).

Introduced a Single Sign-On (SSO) web-framework, significantly reducing integration time from a quarter to days. Following the backend refactoring phase, assumed the role of lead software engineer in the solutions department, overseeing a team of 7 developers. Successfully released the project on time in conjunction with the Travian 5 game, marking a major milestone for the entire company.
  • Implemented a transition of analytics and logs to Graylog, providing the BI team unlimited opportunities to collect valuable information. This transition dramatically simplified the process of adding new BI markers from Mellon's perspective.
  • For the Travian 5 game, developed the 'Achievement' system, integrating it with the in-game event system through a Java backend and web sockets.

20+ years of hands-on experience building, scaling, and rescuing large distributed systems (since 2004). Over the past several years, I have focused heavily on large-scale streaming and real-time platforms. I step into projects under pressure, stabilize critical systems, and help teams deliver secure, reliable, production-grade software.

Specialized in real-time data and streaming architectures: Java, Python, SQL/NoSQL, Node.js/TypeScript, Kafka, Flink, Kubernetes, and cloud-native platforms. Strong background in high-throughput pipelines, event-driven microservices, and API platforms in regulated and high-load environments.

Recent work includes global automotive telemetry pipelines, banking payment systems, and large-scale fintech data platforms handling complex, high-volume workloads.
